How to keep olive trees from fruiting
How to Spray an Olive Tree to Not Make Olives | Home Guides
By Vanessa Salvia Updated September 24, 2020
You may have planted an olive tree (Olea europaea) so that your yard could remind you of the stunning fields of Tuscany, but perhaps you would rather not have to deal with the dark stains left on your patio from the falling olives. An olive tree fruit suppression spray can allow the tree to grow but not produce fruit. An olive tree will survive when planted outdoors in U.S. Department of Agriculture plant hardiness zones 8 through 11.
Olive Tree Growth Cycle
The olive tree has one of the world's longest lifespans. According to Science Times, olive trees have an average lifespan of 500 years, with some living as long as 1,500 years. Olive oil and the fruit of the olive tree are staple foods around the world and have been cultivated by humans for thousands of years. Olive trees need full sun and a long, hot growing season. If they are in an environment where they thrive, they will begin to produce fruit once they are five or six years old. The trees will produce an increasingly large harvest each year, and will produce the most fruit between 40 and 50 years old.
In spring, the olive flower buds start to open. After the floral clusters are fully formed, the petals fall away to reveal the olive fruit. This is called fruit-set. The fruit is ready to be picked in the fall. Olive tree spraying is best done with two applications of spray, before fruit-set happens.
Olive Tree Fruit Suppression
You may wish to practice olive tree fruit suppression for a variety of reasons. For one, according to the University of California Statewide Integrated Pest Management Program, completely eliminating a crop may be desirable because you want to eliminate fruit drop, or due to a desire to increase the tree's yield the next year. If you want to harvest a crop, removing some of the fruit can prevent overloading. Overloaded trees produce smaller, lower-quality fruit, so removing some at the right time can increase the size of the fruit you want to keep.
To completely eliminate a crop, apply an olive tree growth regulator called naphthalene acetic acid, or NAA, at a solution of 150 parts per million in two sprays: Apply the first spray two to three days before full bloom and the second spray a week later.
Olive tree spraying may be done in a single spray applied at full bloom, but fruit may still develop. If your tree is quite large, use a power sprayer. A large tree may require five to 10 gallons of solution.
Applying Olive Tree Growth Regulator
Timing is critical when using NAA for olive tree spraying, according to the University of California. Timing the application can either be based on the fruit size or on full bloom date. Both methods work, but if the weather becomes unseasonably cold, use the fruit-size method.
When using the fruit size method, apply spray when the average size of young fruit is between 1/8 and 3/16 inch in diameter. Timing is 12 to 18 days after bloom generally, in normal weather conditions. Some NAA is mixed with an oil. Do not use NAA above temperatures of 90 degrees Fahrenheit or when it is extremely dry.
Full bloom time is defined as 80 percent of flowers are open, 10 percent of the flowers are not open and 10 percent of the flowers have petals falling. When this goal is reached, wait 12 to 18 days and then apply NAA. Use this method if there is no abnormal change in the weather between the bloom date and the spray date.

- If you don't want to take the chance that a blossom might turn into an olive, spray the tree at the end of winter, sometime before early March, with a growth retardant spray. This keeps the tree from blooming. It doesn't affect the leaf growth or stunt the tree's size, but you won't get to enjoy the tree in bloom.

Looking to keep your olive tree from blossoming to reduce your allergy symptoms, or stop the tree from fruiting? Prevent your olive trees from bearing fruit, and creating a mess in your yard, with our olive tree fruit suppression service. Services are performed from January to April depending on weather and tree condition.
When one thinks about the Olive Tree, it may be as an ancient symbol of peace, a delicious fruit used as a sandwich topping or in a salad, or as a versatile kitchen cooking oil.
Unless you live in an area populated by these specific trees, you may not think about copious amounts of wind-blown, sneeze-inducing pollen but this is what comes to mind for many residents of Arizona when they think of olive trees.
Each year, these trees are responsible for hundreds of cases of allergies and respiratory problems. Olive trees were first planted in Arizona because, not only do they do well in the hot desert climate, they add a luxurious feel to any landscape.
Allergic Reactions from Pollens
However, it did not take long for Arizonans to realize that the small, innocent looking flowers produce massive amounts of pollen capable of provoking severe allergic reactions in those who find themselves near or downwind of the trees. In addition to the large amounts of pollen, falling fruit covers the ground around the tree every year and will rot and cause unsightly stains if not efficiently cleaned up.
Arizona used to be known as a haven for those who suffered from seasonal allergies. The dry, warm dessert air offered temporary relief from pollen found in other areas of the United States. However, largely due to the import of these pollen producing exotic trees, this is no longer the case.
Olive Tree Planting Ban
When the officials of some counties realized what a problem these landscape accessories were becoming, they moved to introduce bans on further planting. The first ban was imposed in 1985, and since then several counties have joined the movement against the planting of new olive trees.
While this has certainly helped the pollen issues in Arizona, the ban is not state-wide, and it also does not require the removal of existing trees. While these implemented bans have certainly cut down on the problem, existing trees still create a copious amount of allergy laden pollen each year and have the potential to outlive several generations of Arizona residents.
The olive tree has rightfully earned its place on the list of the top ten longest living trees, with some estimated at being thousands of years old. Fortunately, there are ways to prevent the trees from producing fruit, which cuts down or even cuts out pollen production.
Olive Tree Fruit Suppression Techniques
Olive tree fruit suppression can be achieved by the trees being sprayed with a compound designed to lessen or even prevent them from bearing fruit. No fruit means no flowers, no flowers, no pollen. Depending on both the weather and the condition of the tree, spraying is done yearly between the months of January and April.
Reducing pollen means that Arizona can again become a haven for allergy relief. And, while yearly spraying can be costly, so is tree removal and treatments for allergies and other respiratory ailments. Also, spraying is a great compromise for those who still enjoy the aesthetic qualities of this knotty and exotic tree.

Olives are oily fruits that are used as food. In the open field, the olive grows in the southern regions and on the coast. Feels great in the Crimea.
[table of contents]
Olive trees can be grown in a greenhouse or at home. It is a symbol of longevity and prosperity. The olive branch is on the coat of arms of Italy. In Athens, a wreath of olive branches was put on the winner of competitions and competitions. The olive also symbolizes peace.
There are several ways to grow a crop. It all depends on the purpose for which the plant is planted. If you want to get fruits, then it is recommended to propagate the tree with cuttings from an already fruiting mother individual. Of course, olive trees are grown from seeds, but in this case, it will begin to bear fruit in 10-20 years. If you are not ready to wait that long, then you can graft a cutting to the tree that bears fruit.

How to grow an olive tree indoors 9002 :
The fastest way to get a fruit-bearing crop is by purchasing a seedling. So you can be sure of the origin of the plant and its ability to produce fruits of a certain size and variety.
There is a division of olive trees depending on the purpose of the fruit. They are table, oilseed or combined. Please note that dwarf varieties are grown at home, but in the garden you will need male and female individuals to harvest. A male or female individual will not produce a crop on its own. Under natural conditions, plant pollen is carried by the wind, and you will have to spread the pollen with a brush or put the pot in a place where there is a draft.
The olive tree thrives in short winters and long dry summers. At temperatures below -5 ° C, an olive family tree feels uncomfortable. With more severe frosts, it dies. Therefore, if you live in the northern regions, plant a crop in a winter garden or greenhouse. Alternatively, purchase a dwarf ornamental variety for growing indoors. What the plant looks like can be seen in the photo.
Growing an olive tree from seed
Purchase dry or fresh olives first, canned is not suitable. The shell of the olive seed is very hard, so to speed up the germination process of the seeds, soak them for 12 hours in a solution of sodium or potassium hydroxide. This is the usual 10% alkali solution. It will partially destroy the shell of the bone and make it possible for the sprout to hatch. Next, cut off the edge of the bone or file it.
There are two options for germinating seeds. This can be done directly in the soil or in compost. To get sprouts, place the stone in the compost and press it a little into the substrate. Next, daily moisten the mass from the sprayer. Please note that the pot must be placed in a warm and well-lit place. This will take a long time, about 3-12 months. Please note that seed germination is only 50%. Therefore, do not be very upset if the seed does not germinate.
After the sprouts have hatched, they are transferred to a separate pot. Little soil is needed. Choose breathable soils and light soils. A mixture of sand and peat will do. Plant transplantation is carried out only after its root system has braided the entire soil. During transplanting, do not clean off the soil from the roots, just transfer the lump into a larger pot. A young plant is transplanted once a year, this should be done in the spring. Once an ornamental olive tree is 5 years old, it should be repotted every three years.
Care of seedlings
Place olive trees in the brightest place in the apartment. Water them regularly during the summer. Remember that in order for the plant to take on the appearance of a tree, the top should not be cut off. Remove side branches and dead leaves. To get flowers and fruits, it is necessary to provide an olive tree with wintering. To this end, reduce watering and place the culture pot in a cool place. There is no need to fertilize the tree. In the summer, top dressing is carried out once every 7 days. It is best if these are complex nitrogenous fertilizers.
The olive has an excellent crown and can be used to make any kind of bonsai. During the dormant period, the temperature in the room should be 10-12 ° C, and in summer - 18-22 ° C. All dried leaves must be cut off, they interfere with the growth of the crown. If you do not move the olive tree to a cool place in winter, it will not bloom and bear fruit. In the summer, spray the branches with a spray bottle.
Growing an olive tree from cuttings
In order to grow a shrub or tree, a shoot 1-3 years old is separated from the mother plant. After that, the cut site is treated with a root stimulator. Please note that the substance must be dissolved exclusively in purified or boiled water. The olive tree is very sensitive to bacteria found in raw water. Next, the cutting is placed in a moist substrate. It can be soil or sand. Before planting, stick a pencil into the substrate, so you get a recess. Place the cutting in the hole and cover it with soil.
Now you have to water the plant all the time and wait. The room temperature must be at least 20°C. Please note that the cuttings really do not like waterlogging, so water infrequently, and try to spray the plants daily. To ensure adequate moisture levels, cover the sprout with a plastic bag and poke a few holes in it for ventilation.
To check if roots have formed or not, gently pull on the stem. If he resists, then the roots gradually grow back. Do not pull with force, as you will simply pull out the plant. The rooting process can take more than 3 months. If three months have already passed, and there are no roots, do not be discouraged. Pay attention to the stalk, if it is green and peppy, then everything is in order, continue to water the European olive.
Planting in a permanent place
Planting an olive tree is carried out after it has taken root. The soil should consist of river sand, garden and soddy soil. Add quicklime to this mixture. Do not forget to put a drainage layer on the bottom of the container with the olive tree. Water the olive tree often, but little by little. Spray the leaves during dry spells. Water for this take filtered or boiled. After about 3-4 years, you will receive flowers and fruits.
Reasons for lack of colors
- Wild plant grown from stone.
- No rest period.
- Insufficient lighting.
In winter, the olive tree may not get enough light. That is why it is illuminated using fluorescent lamps. Be sure to stop watering in winter and do not fertilize the plant. Fruit can be obtained by grafting an olive tree. To do this, a notch is made on the trunk, where a piece of a high-quality tree is inserted that bears fruit. It is usually necessary to graft an olive in the spring. This is done according to the instructions in the same way as a regular fruit tree. If you grow an indoor tree, then you do not need to graft it, since at home the culture rarely bears fruit. Grafting is carried out in a split or sprouting eye.
A mature tree, unlike a young plant, is unpretentious. It perfectly tolerates the lack of moisture and waterlogging. The olive tree that you planted in the garden does not need to be replanted. Just cut dry branches in time and shape the crown as you wish. From April to September, do not forget to water the olive tree with nitrogen fertilizers. So you will accelerate growth and prevent diseases.
European olive - a fruit-bearing tree in your home. How to care for an olive tree at home Olive tree as a houseplant
If my friends and relatives enthusiastically plant decorative flowers at home, then in my apartment you can see only useful plants: lemon (although it is lazy so far, that is, it has not yet given fruit), rosemary, mint. This year there is also an olive tree.
I really wanted to see live how olives grow! Well, of course, try them not from a store jar. And that's what I got...
Olive trees first appeared in the Mediterranean. Now they are grown (in gardens) in India and the Crimea, in Greece and Turkmenistan, in Georgia and Mexico.
By the way, in any country it is a cultivated tree grown by people. There are no wild olives anywhere - this culture "made friends" with man so long ago that there are no traces of its "separate", that is, wild existence.
In our latitudes, many have tried to “engraft” the olive in the garden (it works with heat-loving peaches, right?), but so far no one has succeeded. But to plant such a tree in the house, and even collect the fruits, is not a new thing.
This crop blooms every 2 years. The beginning of flowering is from late April to June.
The flowers look like clusters of forty small flowers, which eventually transform into small "knuckles" of deep purple, black or green. They ripen for a relatively long time - up to 5 months.
A tree (garden tree) can bear fruit for up to 20 years. When this period ends, it should be replaced with a younger one.
How to get a potted olive
It can be planted by rooting a cutting. You can buy it or get it as a gift (although this option is already many times more expensive - a good two-year-old tree with viable roots can cost up to 20 thousand, or even more).
How an olive tree propagates with the help of a cheap (or completely free) cutting, they will tell and show in the video:
You can also grow an olive from a stone. But not from a canned fruit (everything alive has been “nailed” in it for a long time), but from a purchased bone, in extreme cases - from fresh or dried olives.
True, there is a lot of trouble here, and such a tree will begin to bear fruit only at the age of 12, while the “cutting” tree will begin to bear fruit after 3 years.
Are there many types and varieties of olive trees?
Olive trees belong to the olive family, so their "cousins" can be called privet, ash, lilac, jasmine.
About thirty species of olive tree.
The most popular olives on our mainland are the Cape, golden-leaved, and European olives.
All trees can be conditionally divided into three groups:
- Oil olives. They are cultivated for the production of oil, so it is not worth growing one of these varieties at home - their fruits are not so good for snacks. What are these varieties called? Let's say Biancolilla, Caione, Tajasca, Frantogno.
- Universal (combined). Such olives can be both canned and pressed into oil.
- Table varieties. The most delicious, they are best prepared in jars. They are most recommended for indoor gardening. Varieties popular with farmers: Sabina, Lucca, Zinzala, Cerignola. As for growing at home, people really praise the varieties Razzo, Della Madonna, as well as the more “ours” Crimean, Nikitinsky, Urtinsky.
Remember: a tree growing on a windowsill will not overwhelm you with fruits. 15 pieces (600 g) - that's how many olives you can collect from such a plant. But how beautiful it will look!
How to grow an indoor olive tree
- Lighting. It needs as much as possible. A small tree can be kept on a windowsill (even a southern one), and if you put an adult in a corner, then only in the most illuminated one. Loggia, balcony - a great place for a room fruit tree.
- Temperature. In spring and summer (through September), you can keep the olive in any room, and in autumn and winter - in a cool room (where it stays no higher than 12 degrees Celsius).
- Watering. Maximum. Once the top of the soil in the pot is dry, water it well (so that the moisture reaches the bottom of the pot). On average, this is done 2 to 3 times a week.
- Spraying. They should be carried out in summer (in the heat), as well as in winter (if your olive winters not in a cold room, but in a living room, and a battery is working nearby).
- Nutrition. In the spring, the olive should be fed twice a month with preparations (or organic matter, because you have a fruit tree) with nitrogen. In summer, the tree is given a complex mineral fertilizer. Also, some people praise the spraying of olives with succinic acid. This drug can even be drunk by people (vitamin), so it certainly will not harm the fruit tree. The only thing is that succinic acid will not replace the rest of the diet, it can only serve as an addition to it.
- Cutting. We grow this plant only secondarily for the sake of fruits, and firstly, nevertheless, for the sake of beauty. Therefore, in the spring, you can pick up a pruner and boldly form an ideal ball from the crown. When choosing between two branches, always give preference to the stronger one.
It is needed, as the roots of the olive eventually abut against the walls of the pot and outgrow it. The tree is transshipped every 2 years.
- Pot. Best of all - from clay, a couple of centimeters more than the previous one.
- Ground. It can be anything, the main thing is not to be sour. Often "indoor gardeners" take a universal substrate containing compost (humus), sand, soddy and deciduous soil, peat. Also the presence of lime is the norm. Before planting a tree, mineral fertilizers are applied to the soil.
- Do not forget about drainage to the bottom of the pot (broken brick, expanded clay).
Another story - the transplantation of a diseased olive. Most often, these trees suffer from root rot (it starts from frequent overflows). The disease is easily recognized by wilting and falling leaves. The tree must be urgently dug up, cut off diseased roots, treated with activated charcoal.
The olive is transferred to fresh soil. The final touch - you need to remove some branches, because the diseased tree will not have the strength to feed them.
Important conditions without which the harvest cannot be harvested
- 1. 5 months before the start of flowering, strictly monitor the "diet" of your pet: he should receive plenty of watering and nutrition.
- Wintering in a cold room is reflected in the number of fruits. If you move the pot to an insulated loggia or closed veranda from November (or just keep the olive there all the time), the plant will rest and release the maximum number of buds. But remember: it should not be below 10 degrees here, the olive is still afraid of the cold.
- When pruning, remove old branches - it is the developing "young growth" (last year's shoots) that bears fruit.
- The tree can and should be sprayed, the flowers are not afraid of this procedure.
- Make sure the tree gets plenty of light. If the days are overcast (according to the law of meanness, this is always the case ...), you can even highlight the olive.
- Water the tree only when the top soil is dry and not before. Moreover, pour in a little less water than always - during this period, the olive is especially sensitive to overflow.
Olive tree , or olive, belongs to the olive genus. In the natural environment comes across in the form of shrubs and trees. European olive is especially famous . There are about sixty types of culture. The plant is native to Africa, Europe, Australia and Asia. Trees have different structures. They have long branches. The life span of a tree is about 300 years . Culture is considered to be long-livers.
The olive tree can be kept at home for up to 10 years. Next, you need to plant in open ground. It produces good fruit. The mass of the 1st is no more than 5 grams. The leaves of the tree are dark green. The vegetative organs of the plant contain a large concentration of starch. Thanks to this, the culture perfectly copes with a long drought. The bark of the olive is dark in color.
First of all, you should decide for what purpose you expect to grow it. The problem is that there are three types of olives:
- canteens - for use in food;
- oilseeds - for the manufacture of olive oil from them;
- combined - they are allowed to be used in food, and to squeeze oil out of them.
Therefore, based on these criteria, select the variety. Also, the variety must be selected depending on this, in which place you expect to grow (for example, for domestic conditions, select dwarf varieties). If you still decide to grow it to extract the crop, then do not forget that it is a dioecious plant. That is, for the appearance of flowers and fruits, male and female individuals are needed, therefore, representatives of both sexes are planted in one pit.
In addition, the olive tree is pollinated by the wind, therefore, in the absence of wind, the yield may be lower than usual. For the same reason, in domestic conditions, pollen is spread with a brush.
Olive is propagated by 2 methods :
- with seed
- from cuttings.
Olives grow best in climates with mild winters and dry summers. At a temperature of -5 degrees, the tree will already feel bad, a lower temperature will lead to death. In open ground and in climates with severe winters, it is allowed to grow it in heated greenhouses, winter gardens and at home. Buildings should be large and well lit.
Evergreen soil should have exactly neutral acidity, excellent drainage and not be waterlogged. Often it dies due to excessive moisture. Choose a soil rich in limestone. Land for an olive tree is best suited not very fertile, for example, loam or sandy. According to the structure - fine-grained. Certainly the earth must be loose.
Waterlogged substrate and poor soil carrying capacity are the main reasons for the withering of the olive tree . Avoid areas where water accumulates.
When planting, it is imperative to make a dense layer of drainage. You can protect the plant from excessive precipitation by planting it on a gentle slope. It is preferable not to use a fertile substrate. An excessive number of nutrients generates increased tree growth. As a result, the percentage of yield decreases. The ideal land for growing a tree should meet all the required conditions.
Lighting for wood
It usually prefers very warm conditions. In nature, this plant can be found on heavily lit shores. Does not tolerate shaded areas.
Temperature regime for wood
The olive tree is able to withstand temperature drops even down to -15 degrees. With severe prolonged cold weather, the plant will die. During the period of intensive vegetative formation, it is recommended to maintain the temperature from + 18 to + 20 degrees. At the turn of flowering, return frosts can affect high yields. Intense heat combined with dry air also harms the tree.
Watering the plant
The crop responds well to measured soil moisture. In the spring-summer season, it is preferable to water the substrate regularly. Prolonged exposure to dry soil leads to leaf fall. In winter, the number of waterings must be reduced. Moisten enough as the substrate dries out. For him, it is preferable to use warm soft water.
The plant does not require special conditions. In hot weather, it is recommended to increase the degree of presence of water in the air. To do this, you will need to sprinkle the plant with water at room temperature several times a day. In drought, it is preferable to spray warm water on the tree.
Features of transplanting a plant
The plant can experience a change in soil and substrate. It is not advisable to transplant adult olive representatives. The root system is often damaged. For transplantation, it is necessary to prepare a suitable place. Growing in heavily rotten and dry soil often results in wilting. In the natural environment, the plant can be found in the rock. Therefore, it is possible to add charcoal and pieces of brick to the soil during the planting period.
He needs to be sanitized in a timely manner. European olive is often damaged by various pests. In the open air in early spring, it is necessary to remove the affected areas. A houseplant can be given a beautiful compact shape. To do this, it is necessary to remove weakened processes and long branches. The plant is very tolerant of shearing.
In one vegetative stage, the crop will give excellent growth. If the plant is grown for harvesting, features should be considered. The fruits are usually formed in the shoots of the previous summer. Therefore, cardinal pruning can eliminate a huge number of olives.
A plant in a garden plot
In the open air, the European olive perfectly takes root and bears fruit well in the southern part of the Crimea and the Mediterranean. In more severe circumstances, the culture can be grown in a spacious room, conservatory, glass greenhouse or warm room. Frost at -5 degrees will ruin weakened branches. At -15 degrees, it will die. Even with a slight decrease in temperature, a sudden deterioration in the taste of fruits and oils was noticed. For harvesting, garden species should be purchased. Bred subspecies provide constant fruiting.
How to feed the plant?
Nutritional deficiencies can be compensated with nitrogen. The procedure must be carried out once a year. For 1 weave, no more than 1.2 kilograms will be required. It is allowed to plant near with olives natural producers of nitrogen (legumes). In addition, it is recommended to add fertilizer to the soil from time to time.
Container tree growing
To grow good olives indoors, you first need to prepare the right variety. It is preferable to buy a dwarf culture. The container must initially be selected large enough. The volume of the pot should be at least 60 cm deep and wide. Be sure to make several large holes in the bottom of the container. The most important enemy of olives is the high constant humidity of the earth. Therefore, in order to grow a good indoor tree, it is necessary to prepare a loamy or sandy base.
The soil must be at least 3 cm deep before the next watering. Container olive is more demanding. For its full formation, gentle pruning should be constantly carried out. It is not recommended to allow thickening of the main branches.
Major problems and pests
The evergreen olive tree is particularly susceptible to pest and disease attack. The biggest danger to an evergreen plant is dangerous black bugs. Excessive use of chemical protective preparations is not the best way to display on the yield of olives. Therefore, it is preferable to support immunity with organic and mineral preparations.
Tree often damaged:
- dangerous whitefly;
- olive moth.
In the open air, nibbled buds and leaves show a colony of caterpillars. Sudden drying of branches and leaves indicates infection with dangerous verticillium wilt. A fungal infection usually does not respond to treatment. If the evergreen tree is not protected in time from the affected areas, the plant will die. When infected in an open area, it is necessary to avoid a place for further landings.
Influence of the plant
With the right care growing olives at home does not bring difficulties. It is enough to guarantee the culture good lighting and timely nutrition. After some time, fragrant inflorescences and the necessary olives will appear on the tree. A container plant can produce about 2 kg of fruit.
Olive oil contains lecithin. The intolerance of the component generates an allergic reaction. The allergy that has appeared also has the ability to be of a cross nature. People who react to the flower, olives and shrubs of the Shrovetide family, most react to the oil. Often the formation of the reaction is associated with a hereditary predisposition. It is preferable to use refined oil to reduce the likely manifestations.
Propagation of the olive
Evergreen tree can also be propagated by seeds , and cuttings .
Seedlings must be treated with the correct alkali solution before sowing. The softened seed coat ensures the best germination.
For planting, it is necessary to prepare culvert substrate . The mixture should include leafy soil and coarse sand. In addition, crushed wood ash and broken bricks can be added to the soil.
European olive sowing depth should not exceed 3 cm. It is important to continuously maintain the moisture content of the substrate. Even freshly harvested olive seeds have less than 50% germination.
Olive tree from seeds late fruiting . The first olive blossoms may appear only after 10 years. The tree can be used for grafting. Cuttings ensure the preservation of all original varietal characteristics. Fruiting will come in 2 years. Seedlings must be placed in the soil under a slope. To form a greenhouse effect, it is preferable to prepare cellophane. It is necessary to constantly ventilate and spray the cuttings. After a good rooting of the European olive, you can transplant all plants into single pots.
Why doesn't the plant bear fruit?
The evergreen olive tree can begin to bear fruit a couple of years after planting. Time of first fruit development depends on the growing method. Suitable conditions promote accelerated flowering. There are species that, regardless of the method of reproduction and care conditions, produce fruits only 10 years after planting. It is always recommended to specify all the characteristics of the planting material before buying.
The olive tree belongs to the olive family. In the Mediterranean, in the south of the Crimea, in the southern regions of Russia and in other areas with a mild climate, this plant is grown in open ground. In more severe conditions, you can grow it in a winter garden or in a spacious, bright room, including an apartment. Trees of table varieties, with proper care, will regularly bear fruit.
The olive tree is a long-lived tree. It has been growing for over 500 years. In the Garden of Gethsemane (Jerusalem), olive trees grow, which, according to scientists, reach 2000 years old. Greece is considered the birthplace of the olive. According to an ancient legend, the goddess Athena sent an olive branch to this fertile land, from which the first tree grew.
Olives are a real treasure for the human body. They contain more than 100 useful substances. It seems that nature itself took care of the health, freshness and beauty of man, giving him these priceless fruits.
Olives are the simplest and most effective prevention of diseases of the heart, blood vessels, gastrointestinal tract and breast cancer. To achieve the desired effect, it is enough to eat only eight olives a day or season salads with olive oil.
Oliva is the personification of deep inner cultural ties. At least that's what Thomas Friedman thinks. He expressed his thoughts on globalization and cultural identity in his sensational book "The Lexus and the Olive Tree", published in 1999 year.
Ornamental olive tree
Usually the domestic olive tree is grown not for its fruit, but because of its ornamental, very attractive appearance. Today, there are many varieties of this wonderful culture that have characteristic features. For indoor cultivation, varieties that reach no more than 2 meters in height are suitable, which are suitable for growing in a container.
The olive tree at home is a miniature, evergreen plant with a spherical and compact crown. Young plants have a light gray bark, older ones have dark bark. The leaves are dense, narrow, lanceolate, dark green. They stay on the branches for a long time, do not fall off even in winter. They are updated every 2 years.
Flowers white, small, bisexual, with goblet calyx. The fruits are elongated-oval one-seeded drupes, about three centimeters long, which have a pointed or blunt end and a fleshy pericarp. The color of the fruit may be green or dark purple, depending on the variety. Its average weight is 15 g.
Olive tree at home
Many are concerned about the question of whether this plant will take root in our apartments? Under natural conditions, the olive tree grows in semi-deserts, on rocky mountain slopes, and on saline and poor soils. Sometimes where no other plant can survive.
The olive tree looks silvery from a distance, because its dark green narrow leaves on the underside are covered with a bluish bloom. It is even sometimes mistaken for some kind of willow.
Affects the drought resistance of the olive. In this, perhaps, the date palm can be compared with it. Both of these trees love when their crown is warm and their roots are cool. In search of moisture, they direct their roots very deep, reaching groundwater, sometimes at a depth of 5-7 meters.
Care for the olive tree
At home, this undemanding plant does not require much care. He needs a well-lit "place of residence", abundant watering during the period of active growth (March-August). In autumn, watering the olives is reduced, and in winter, when the plant seems to freeze, the soil in pots is moistened no more than twice a week.
Domestic olive tree, care of which is easy even for a beginner grower, propagated by seeds, grafts and cuttings. To grow a tree solely for decorative purposes, the plant is propagated by seeds.
Preparing the seeds
This method is quite lengthy, but it allows you to see the entire development cycle of the tree and guarantees its high survival rate. Before planting, they are soaked for 12 hours in a solution of caustic soda. Then they are rinsed with water and planted in a pot with a diameter of no more than nine centimeters to a depth of two centimeters. The soil should be moist and nutritious. In addition, you should pay attention to the fact that the earth is loose, light. Such a mixture consists of leaf and sod land, sand, peat in equal volumes. Large, oblong-shaped olive seeds are planted in small (5 cm in diameter) pots no deeper than 1 centimeter.
You will see the first sprouts in 2 months. At this time, you should carefully monitor the moisture content of the soil. It is recommended to water the crop as the clod of earth dries up and try not to allow it to become either waterlogged or dry out. Germination of seeds, as a rule, is 40-50%. Often the seeds do not germinate or produce non-viable, weak shoots that die after a short time. If we grow an olive tree from seeds, then the first fruits should not be expected until ten years later. If you want to speed up the timing of fruiting or flowering, grown seedlings must be grafted onto varietal plants.
Surprisingly, you can even grow an olive tree at home from a seed. True, to obtain a good result, it is necessary to carry out a long preparation process.
Propagation by cuttings
In this case, the olive tree retains all the maternal characteristics. The first fruits appear in the third, in rare cases in the second year. It is necessary to take two or three summer branches. Their sections are carefully treated with a growth stimulator, then planted in sand ten centimeters deep, the seedlings are covered with glass on top (polyethylene can also be used for this purpose).
The optimum temperature for rooting is 25-27 °C. It usually occurs within a month, after which shoots begin to appear. After 3-4 months, the root system will be fully formed, and the seedling can be transplanted to its permanent place in a large pot.
The olive tree, which is easy to care for at home, loves good lighting, so south window sills are suitable for young plants. Mature trees can be placed in a room in any well-lit place.
In the warm season, it is useful to take the plant out into the air - into the garden or onto the balcony. An abundance of light is especially necessary during the period of plant growth and bud formation. If it is not enough, the olive will slow down the growth. In winter, the tree needs additional lighting to prevent leaf fall.
The air should be warmed up to 18-22 °C - this is the most comfortable for this crop. During the dormant period (in winter), the temperature should not exceed 13 ° C. Such conditions will contribute to the laying of flower buds. Watering during this period is reduced, fertilizing the soil is not recommended.
Blossoming olive: care
During flowering, the plant needs more care. At this time, it is very important to monitor the condition of the soil. Watering is carried out as needed (when the top layer of the earth dries). If there is not enough moisture, the leaves of the plant fade, curl up, and then fall off. It can even lead to the death of the tree.
Slightly yellowish or completely white flowers with a delicate and refined aroma bloom in mid-June. At home, the tree is decorated with delicate flowers for several months. The plant is pollinated by wind and insects, but daily shaking of the branches is necessary for a home olive. With self-pollination, fruits can be tied in different sizes, and cross-pollination significantly improves their quality and yield
Despite the fact that the olive tolerates dry air well, we recommend spraying its crown in extreme heat. Until the age of four, the plant needs an annual transplant. This is usually done in early spring, and it is not necessary to change the entire contents of the pot, it is enough to replace only the topsoil with a more fertile and fresh one.
Regular pruning will help you to give the olive crown a neat and spherical shape. Carrying out this procedure, remove dry and weak branches, shorten long shoots, create the desired shape. If you decide to grow an olive tree for fruit, remember that the bulk of the crop comes from last year's growth. Therefore, pruning must be done very carefully so that you can enjoy the next year's harvest.
Despite the somewhat laborious growing process, the olive tree is unpretentious and not prone to diseases. With regular and proper care, two years after planting, you can admire the blooming olive and get a good harvest (up to 2 kg of fruit per year).
During the active growth and development of the olive tree (February-October), regular (once every fifteen days) top dressing should be carried out with solutions and infusions of organic and mineral fertilizers. For better fruit setting and development in the summer, double superphosphate is useful. For this, an aqueous solution of a substance is used at the rate of five grams per liter of water. In addition, it can be mullein - a two-week infusion, diluted 15-20 times before use.
From November to February, the olive tree, which is kept indoors, sharply slows down all metabolic processes, and it goes into a dormant state. In winter, top dressing is not carried out.
If you set out to grow a domestic olive tree, you must remember that insufficient light, excessive watering and very high air temperatures in winter will not allow you to "tame" such a tree in your home. If you manage to overcome these obstacles, then you need to be patient, because compared to most plants that experienced growers know about, the olive develops very slowly, and it does not bloom too quickly. But lovers of indoor plants are attracted by the fact that you can grow it all your life - this small tree lives, according to scientists, for at least three thousand years.
Olive tree (Olea europaea) - or the so-called "Olive Tree" belongs to the Olive family. Mostly there are olive trees and shrubs.
Olive grey. The most widespread species is the European olive. There are about 60 species. The native places of the plant are considered to be Southern Europe, Africa, South Asia as well as Australia.
The fruit is mostly green when harvested. After cooking, they turn black, come with and without bones. Trees that are uneven can be knotty. Branches are long and can hang down. The mass of the ripe fruit of the olive tree is 4-5 grams.
This plant can live up to 300 years. Many call him a long-liver. It is recommended to keep the Olive Tree in the room for up to 10 years. Then transplant into the ground. It grows rather slowly. The leaves of the tree are green-gray. In them, she can collect starch, which helps in very dry weather.
Olive tree care:
The olive tree is a very thermophilic plant. Grows in sunny areas. Doesn't tolerate shade. But it can still withstand light partial shade.
The olive tree is quite a thermophilic plant. But sometimes it can withstand low temperatures down to minus 11-15 ° C. But of course a short time. At lower levels, it dies. In warm seasons, the olive tree loves warmth. The average temperature for its good condition is 18-20 ° C. When it blooms, temperature conditions must be observed. At minus 3 - 5 ° C, flowers can be damaged. But still, if the temperatures are very high, this is also harmful.
The olive tree is well watered. In warm seasons, it is often necessary to water the plant. If the soil is dry, the leaves may fall off. In winter, you need to water much less, following the soil of the plant. For irrigation, it is good to take water that is not cold, standing at an average temperature.
Olive tree is neutral to high humidity. If the air humidity is high, then the air temperature should be high. When it is very hot, you can spray the leaves twice a day.
Olive tree is a plant that, like all others, must be fertilized with mineral fertilizer. In order for it to winter well, it is necessary to feed it with nitrogen in the spring, and in summer nitrogen fertilizer helps to prevent it from freezing out in winter. Approximately once every two weeks you can feed.
The olive tree is not very picky. It does not require special soil. But if the soil is rotten and dry, then it will still not grow. It is recommended that the soil contains a sufficient amount of lime, the soil is rocky and sandy. These plants have very strong roots. Sometimes they are even found in the rock. You can add pieces of brick or charcoal to the soil.
The olive tree mostly propagates vegetatively and also by seeds. But when it is hot, it is recommended to propagate by cuttings. Still, gardeners prefer to propagate the olive tree by seeds. This method is more suitable as it is demanding in reproduction. Seeds can germinate in 2 months. From seeds, the plant can bloom only after 10 years, from cuttings after 4 years.
The olive tree is very useful. Fruits are recommended to be eaten as it improves metabolism. This product is also very useful in cooking. Popular use in salads and soups. Rich in vitamins. The use of olives once a day leads to an improvement in the condition of the body and weight loss.
Olive tree - diseases and pests:
The olive tree is a plant that can be attacked by olive moth, whitefly or the so-called "butterfly". The caterpillar eats leaves and buds. If the inflorescences are infected, then they must be cut off immediately. When it does not help, you can use karbofos. The butterfly can infect the leaves, later they turn yellow and fall off. In this case, spray with soap and water or use a suspension of pyrethrum, decis.
European olive or European olive (Olea europaea) - is a beautiful tree, an adult specimen is often clumsy. The olive is widespread in the Mediterranean region, where it has been cultivated for centuries. The olive tree is a symbol of peace and new life. Greek legend says that the first olive tree grew on the Acropolis from the spear of Athena, its destruction was associated with severe punishment. Olives are primarily useful plants. Wood is used to create various household items, due to its slow growth it is quite expensive. The fruits are widely used in cuisine and cosmetics.
How to grow an olive tree
European olive grows as a tree or a large shrub, it can reach a maximum of 15 m in height. It has a highly branched but transparent crown. It grows slowly, long-liver - you can often find several hundred summer specimens. The trunk is not simple, gnarled, covered with gray bark, empty in the middle. The bark of young trees is greenish and smooth. Olive leaves are leathery, arranged oppositely, 3-8 cm long, dark green above, silvery below. Small flowers are rather inconspicuous, slightly fragrant, have a creamy yellow color. Appear in the spring on last year's shoots. For pollination, pollen from another tree is needed. The fruits are drupes called olives, in Europe they begin to be harvested when the fruits have not reached full maturity. The fruits can be green, white, reddish, purple or black. Thanks to their use, the fruits are divided into larger and fleshy - table olives, smaller and hard, intended for the production of olive oil.
European olive loves the sun. Should grow in the most sunny place. In summer, it is better to take the pot outside, gradually accustoming it to direct sunlight. First set for 10 days in partial shade, moving to a brighter place in the following days. If this is not done, there is a high risk of leaf burns (brown spots appear on the leaves).
Olive soil should be primarily permeable, in the case of large specimens, clay. The best are sandy soils. The substrate should be enriched with materials that improve permeability (gravel, expanded clay, perlite), pour a layer of drainage on the bottom of the pot.
The olive tree does not require much watering. The ground should not be too wet. Overwatering should be avoided as it can lead to root rot. True, olives tolerate short-term drought, but the earth should not dry out completely. In their natural environment, plants have to wait a long time for rainfall, so they are adapted to extract water from the ground with extremely wide branching roots. At home, this is not possible, so it is better to keep the ground always slightly damp.
Fertilize the tree regularly from March to September with a universal multi-component fertilizer.
During the growing season the temperature must be as high as possible. In winter, 10 °C is sufficient. In a bright conservatory, they can overwinter at a temperature of 15 ° C. Olives are not frost-resistant, adult specimens can withstand short-term temperature drops to -10 ° C. Young specimens are especially sensitive to frost, especially the roots are immediately damaged. Plants grown at home, exposed in the summer to the open air, must be removed in a timely manner.
Olives are pruned in early spring or autumn. It is worth regularly shortening the shoots to give a good shape.
