How to take care of a hamlin orange tree


The Popular Hamlin Orange Tree

If you’re looking for a super juicy sweet orange to grow, you can’t go wrong with the Hamlin orange tree. Although these trees can be difficult to find, it’s time well spent if you can buy them online or at a local nursery

Hamlin Orange

A favorite for snacking and juicing, Hamlin oranges are a popular orange in the U.S. Here’s another reason to love the Hamlin orange tree: The fruit ripens in the earlier part of the citrus season, so you can enjoy oranges as early as October and on through March in some areas.

Let’s dive in and learn all about the amazing Hamlin orange tree.

History of the Hamlin Orange Tree

The true origin of oranges is a bit of a mystery, but it’s widely believed that the first cultivation of oranges started thousands of years ago in eastern Asia.

The Hamlin Orange, otherwise known as the sweet orange, was an accidental creation in 1879. A farmer based in Glenwood, Florida by the name of A. G. Hamlin (makes sense, right?) crossed a pomelo, a Southeastern Asian citrus fruit, with a mandarin. This is the more modern version, however.

The Hamlin orange tree became a popular variety with enthusiasts who wanted an early fruit while they waited for the popular California Valencia crop to become ripe in the spring. Hamlin oranges filled the void for people who were looking for another good juicing orange.

Hamlin orange trees are one of the top juice oranges grown commercially in the United States. Moreover, in Florida, these beautiful trees are the most widely grown early harvest sweet oranges, making up about 50% of Florida’s orange crop.

Fruit Tree / Fruit Characteristics

The Hamlin orange tree produces a nice-sized heavy crop with high yields in the early part of the citrus harvest season. Hamlin orange trees have broadleaf leaves and white flowers.

The Hamlin orange tree is also a cold resisting powerhouse. It’s even considered to be the strongest sweet orange tree that’s cold tolerant. One account proved the tree withstood twenty-degree weather with a twenty-five mile an hour wind. A bed sheet over the leaves paired with a thick blanket near the base of the tree protected it from the elements. 

Hamlin oranges are known for being deliciously juicy and their low-acid content makes them favorites for snacking and making orange juice. They are round with smooth skin, and their color is dull orange to dark yellow. The ripened fruit has very few seeds.

The Hamlin orange tree grows to approximately 2 ½ inches in diameter. Some Hamlin oranges may be about the size of a baseball. They’re slightly larger than some other oranges.

Note that Hamlin oranges aren’t grown to be beautiful additions to your fruit bowl. They may actually be quite unattractive. However, people grow these incredible oranges for their sweet juice.

Large Orange Plantation

Planting Zones

The Hamlin orange tree grows best in USDA Hardiness Zones 9-11.

If you happen to live in Zone 9, you have an advantage over many other fruit growers in the country because you can grow several types of citrus trees, including the Hamlin orange tree.

Zone 9 is the thermal belt, where the weather is affected by both interior and coastal weather patterns. Though it was mentioned before that this is the strongest of the orange trees when it comes to cold weather, subzero temperatures and multiple feet of snow in some of the worst winters would be damaging to the tree.

Like most citrus trees, the Hamlin orange tree can be grown in a pot so that it can be moved indoors during the colder months. For those who are in the northern states and parts of Canada, keeping your Hamlin orange tree in a container may be the best option for you.

A container allows for easy relocation to a greenhouse or garage for those harsher elements, and then back outside when the sun is shining bright. Be sure to plant your tree in the biggest pot you can easily move with a dolly.

Size and Spacing

Mature full-sized Hamlin orange trees will grow to be between 20-25 feet tall. Dwarf varieties are 8-10 feet tall.

The width of a mature tree is between 6-8 feet.

Pollination

Hamlin orange trees are self-pollinating. However, if you want to get better yield from your orange trees, check out this video that will show you how to help your tree pollinate.

Tree Care

In heavy crop years, small fruit size can sometimes be a problem when it comes to the market for fresh fruit. Inadequate soil potassium levels can contribute to the size of the fruit, so be sure to test your soil.

The good news is that even small Hamlin oranges yield a high ration of flesh to peel.

If you want to fertilize your Hamlin orange tree, fertilize it in early spring or late winter.

Hamlin orange trees need soil with a neutral pH (6.6-7.3pH), good drainage, and can benefit from airing the soil so they can breathe. Being sure to not over mulch trees will also help with healthy growth.

Sunlight

Citrus trees, including the Hamlin orange tree, enjoy full sun from eight to 12 hours per day.

Technically, Hamlin orange trees will grow in partial sunlight, but you’ll maximize your harvest if your trees receive a full day of sunlight every day.

If you’re growing your trees inside, place them beside a window that faces south. The area should have good airflow. During darker winter months, you can supplement the sunlight with grow lights.

Hamlin Orange Trees Soaking Up The Sun

Watering

If you grow your Hamlin orange tree in a container, it will need more water than those planted in the ground outside. You will need to water your tree two to three times per week in the spring.

When temperatures rise in the summer, you will need to water your Hamlin orange tree every day, keeping the soil moist. However, don’t let your soil get soggy and limit the amount of water that the tree receives. Otherwise, the tree will contract root rot.

One good way to check to see if your tree needs water is to put your finger in the soil to the depth of two to three inches. If it feels dry to the touch, your Hamlin orange tree needs to be watered.

Misting Your Hamlin Orange Tree

Equally important, if you’re growing your Hamlin orange tree inside, remember that most homes don’t have the humidity that citrus trees need. Because of this, you need to mist your Hamlin orange tree several times every week.

Pruning

The Hamlin orange tree needs regular pruning to encourage the trees to grow outward. Doing this will increase your tree’s fruit production. A common trade practice is to reduce the amount of orange buds that grow. Reducing the tree’s orange buds to roughly twenty percent will help the tree put more energy into the remaining oranges and will then produce larger and even sweeter Hamlin oranges.

Before pruning, disinfect your pruning tools with a 10% bleach solution. This is nine parts water and one part bleach. Rinse your pruning tools after using the solution.

Cut back broken, diseased, or dead branches as they develop over the course of the year. Be sure to eliminate any crossing or rubbing branchings so that you can encourage the outward growing habit. This will ensure that sunlight reaches every branch.

Diseases & Care

Hamlin orange trees may be vulnerable to sooty mold, white flies, and leaf miners.

For more information about diseases that affect this tree, see “Hamlin Orange Tree Diseases and Care.”

Harvesting Hamlin Oranges

The Hamlin orange tree is high-yielding; so, a good collection of the trees will provide you with a great stock of oranges to juice and eat. The harvesting season for these oranges is October to December.

In the off-season fruit is still produced; however, at a smaller level. If you’re running a large-scale orchard, having other commercial-grade fruit that grows in its off-season is ideal, but for personal use, this tree is perfect.

Common Uses for the Hamlin Orange Tree

The secret to the sweetest and most delicious Hamlin oranges is to leave them on your trees until they’re fully ripened. Once ripened, you can eat these tasty little oranges straight off the trees or juice them.

You can store Hamlin oranges for up to three days at room temperature or in the refrigerator for up to two weeks. Note that if you do store them in the refrigerator, the flesh may break down.

If possible, try to store your Hamlin oranges at around 50 degrees. If you have an attached garage, that can be the ideal place to store them.

What Do Hamlin Oranges Taste Like?

Hamlin oranges are incredibly juicy, and they’re not too acidic. This makes them perfect for easy and quick snacking. Hamlin oranges also make delicious orange juice.

Orange cake with dried apricots and powdered sugar.

Cooking

The best and juiciest Hamlin oranges will feel heavy for their size. Later in the season, these oranges will also be soft and that’s fine as long as the skin is still elastic.

These oranges are perfect for eating and juicing, and they’re not as beautiful in the fruit bowl as some other varieties.

Of course, you can use Hamlin oranges for any other recipe that calls for oranges, orange peel, or orange juice.

Eating Raw

Like all oranges, you can enjoy Hamlin oranges raw right off the trees if you allow them to fully ripen.

Enthusiasts say that Hamlin oranges lack the “zing” of Valencia oranges. If you want to jazz your Hamlin orange juice up a bit, consider mixing it with some tangerine juice. Tangerines ripen at about the same time as the Hamlin orange tree.

Adding tangerine juice to your Hamlin orange juice will add not just some spicy zest, but it will also brighten up the color. We recommend using the juice of one tangerine for every four Hamlin oranges.

Another recommendation we’ve seen is to mix your Hamlin orange juice with grapefruit juice for an interesting option.

Canning / Freezing / Drying

There are countless ways to preserve oranges. If you’re lucky enough to have a bumper harvest, you can find plenty of ideas online for how to can, dry, and even freeze your excess fruit.

Canning

Canning oranges is a popular way to preserve this tangy fruit. You can use the canned oranges in fruit salads, and you have the option to can them whole or in segments.

Freezing

Our favorite tip for freezing oranges is to juice them and freeze the juice in ice cubes. Once frozen, pop the juice cubes into a large freezer bag.

Alternatively, if you’re using your oranges for juice only, you can pop the whole oranges right into the freezer.

Drying

Dried orange slices are beautiful and fragrant in potpourri or as decoration. The dried slices can also be added to a pitcher of iced tea or homemade lemonade to give it a wonderful flavor.

Another way to dry oranges is to preserve the zest, which can be delicious in recipes. To dry your orange zest, zest your oranges and place the zest on a baking tray in a thin layer.

Once it’s completely dry, put the zest in a jar with an airtight lid. If it’s stored in a dry, cool, dark place, it will keep for a long time. However, after a few months, it will start to lose its potent flavor.

Recipes for Hamlin Oranges

Whether you’re eating your oranges straight off the tree, juicing them, or using them in recipes, there are endless ways to enjoy this delicious citrus fruit. Here are some of our favorite recipes.

  • Orange Marmalade
  • Orange Jam with Warm Spices
  • Sunny Southern Preserved Oranges
  • Whole Orange Almond Cake
  • Orange Sweet Rolls
  • Cranberry Orange Walnut Bread
  • Classic Orange Beef
  • Gingered Orange Gratin
  • Citrus and Avocado Salad with Orange Water

Another interesting use for Hamlin oranges is to make candied citrus peel out of the peels. There’s no need to waste even one bit of this delicious orange.

Basic Hamlin Orange Juice

Here are the steps to making juice out of your Hamlin oranges.

  1. Since the Hamlin orange is cultivated for juicing, cut it in half and squeeze out the juice with an electric or manual juicer.
  2. The skin is thin, so it’s harder to peel the Hamlin orange by hand. We recommend peeling it with a thin-bladed knife. Cut off a ÂԚ½-inch disk from the bottom of the orange, then insert the knife between the orange peel and the flesh to cut the peel away.
  3. When you’ve removed the peel, squeeze all the remaining membranes to extract your juice.

Health Benefits of Hamlin Oranges

The health benefits of oranges are well documented. With only 47 calories for half of a large orange, this fruit packs a powerful nutritional punch that’s full of vitamin C, fiber, folate, thiamine, and rich antioxidants.

Here are some of the ways oranges can help us be healthier.

  • Heart health
  • Kidney stone prevention
  • Anemia prevention

Where To Buy This Fruit Tree?

It’s very difficult to find Hamlin orange trees in stock, so if you find them, grab them as quickly as you can. In some areas, you may get lucky and find them at local nurseries.

Another thing to keep in mind is that certain states don’t allow the Hamlin orange tree to be shipped into the state. For instance, we found a Hamlin orange tree on Amazon, but the tree can’t be shipped to California, Texas, Louisiana, or Arizona.

  • Detailed Care Instructions

Features

This variety is popular for its early-season, high yields of sweet, nearly seedless fruit and its improved cold tolerance compared to other Oranges. The fruits are excellent for making fresh squeezed juice. To make orange juice, lightly smack each fruit on the counter before cutting it in half. The orange may be squeezed directly into a drinking glass or strained to remove the pulp. Oranges and their juices are a good source of vitamin C.

Uses

Utilize citrus trees in the landscape just like any ornamental tree. Give enough space that light is available from all sides, away from the shade of larger trees or buildings. A great plant for large patio containers where the fragrant flowers can be enjoyed and the fruit easily picked. Can also be grown indoors if space and ample sunlight can be provided.

Plant Feed

Apply a complete fertilizer formulated for fruit bearing varieties.

Watering

Water 2 - 3 times per week until established.

Soil

Organic-rich, well-drained soil.

Basic Care Summary

Plant where tree is accessible from all sides so that fruit can be easily harvested as it matures. Apply fertilizer formulated for citrus trees in late winter into early spring. Prepare fruit by peeling away the outer skin, slicing, or squeezing for juice.

Planting Instructions

Plant in spring or early fall to give plants the best start.

Choose a location that will allow roots to spread and branches to grow freely. Space plants far enough from building foundations, walls, and decks so that the growing foliage won't crowd the structure. Consider whether tall trees or shrubs will block windows or interfere with the roof or power lines.

To prepare the planting area dig a hole as deep as the root ball and three times as wide. After removing the soil, mix it with some compost or peat moss. This enriches the soil and loosens the existing dirt so that new roots can spread easily.

To remove the plant from the container, gently brace the base of the plant, tip it sideways and tap the outside of the pot to loosen. Rotate the container and continue to tap, loosening the soil until the plant pulls smoothly from the pot. The container can also be removed by carefully cutting it down the side.

Set the plant in the hole. If the root ball is wrapped in burlap fabric this must now be removed along with any string or wire securing the burlap. If roots are tightly packed gently rake them apart with your fingers.

Return the soil to the planting area packing it firmly around the root ball. Fill the hole until the soil line is just at the base of the plant, where the roots begin to flare out from the main stem.

Water the plant well then add a 2” (5cm) layer of mulch, such as shredded bark, around the planting area. Keep the mulch at least 4” (10cm) away from the trunk of the plant as this can keep the bark too moist and cause it to decay.

Watering Instructions

Depending on rainfall, new plants need to be watered weekly through the first growing season. A slow, one-hour trickle of water should do the job. During hot spells thoroughly soaking the ground up to 8” (20 cm) every few days is better than watering a little bit daily. Deep watering encourages roots to grow further into the ground resulting in a sturdier plant with more drought tolerance.

To check for soil moisture use your finger or a hand trowel to dig a small hole and examine the soil. If the first 2-4” (5-10cm) of soil is dry, it is time to water.

Monitor new plants through the first two years to make sure they are getting the moisture they need. After that they should be sturdy enough to survive on their own.

Fertilizing Instructions

Established trees should be fertilized every 2-3 years. Feed in early spring when plants start growing.

Fertilizers are available in many forms: granulated, slow-release, liquid feeds, organic or synthetic. Determine which application method is best for the situation and select a product designed for trees and shrubs, or go with a nutritionally balanced, general-purpose formula such as 10-10-10.

Always follow the fertilizer package directions for application rates and scheduling. Over-fertilizing plants or applying at the wrong time during the growing season can result in plant injury.

Pruning Instructions

Pruning may be needed to remove dead branches, encourage bushier growth, promote more flowers, or maintain a specific size or shape.

Dead branches should be removed close to the trunk, flush with the bark. When pruning to control a plant's size or shape, cuts should be made just above a leaf bud and at a slight angle. This bud will be where the new growth sprouts.

Many shrubs can be regularly sheared to keep them shaped as a hedge, edging or formal foundation planting.

Always use sharp, clean tools when pruning. There are many tools available depending on the job. Hand shears, pruners, and loppers are ideal for most shrubs. Pole pruners and tree saws are better for large, mature shrubs or trees. If a tree is so large that it can't be safely pruned with a pole pruner, it is best to call in a professional tree service.

The technique of growing oranges in Russia in open ground conditions has not yet received due distribution, although their successful cultivation in greenhouses or at home, the so-called room conditions for obtaining fruits, is practiced by many gardeners. In this article you will find several recommendations for planting and caring for orange trees, several successful varieties that, subject to agricultural practices, will successfully bear fruit. Given the global warming of the climate, the cultivation of oranges in a country house or plot also becomes possible in a number of regions of the Russian Federation, especially if the conditions are met and the use of zoned, cold- and frost-resistant varieties.

Let's start with a little history.


EVERYTHING YOU NEED FOR THIS ARTICLE IS HERE >>>

Common sweet orange - Citrus sinensis Osb. (C. aurantium sinensis L, Aurantium sinensis Mill., C aurantium Lour) - belongs to the subfamily of orange (Aurantioideae) of the rue family (Rutaceae). The word "orange" comes from the German "anfelsin" - Chinese apple. The English, French and Spanish names are related to the Arabic "nareng".

According to F.H. Bakhteev, the question of the birthplace of the orange among researchers is not sufficiently clarified. N.I. Vavilov (1935, 1958), the Tanakh considered India as the main place of origin, and China as the secondary one. Not known in the wild. Came to Europe by the end of the 15th century, and soon after that - to Africa and America.

In Transcaucasia as early as 1197, it is mentioned in a poem by Nizami, a well-known Azerbaijani poet (MA Kaptsinel, 1950). According to M.A. Kapcinel, in the notes of the Georgian geographer Vakhushti (early 18th century), it is noted that oranges grow in Batumi and Gonio. Orange came to the Sochi region in the 19th century.

Useful properties of oranges

According to P.M. Zhukovsky (1971), the orange is the best and healthiest fruit in the world.

The oil helps with hand tremors and toothache. The sour juice of orange stops the secretion of bile and vomiting, it flushes the stomach, stimulates appetite and removes small and large worms from the intestines. Helps with bone pain. And the oil from the peels, together with the gum, cures lichen. In this case, the orange is harmful to the chest and nerves. Its harmful effect is eliminated by honey and dates (healer of antiquity, Armenian doctor of the 15th century Hamasnatsi).

Empress Catherine's personal physician Ambodik pointed out that the use of orange leaves ground into a fine powder or boiled in water in a sealed container completely relieves epilepsy. Flowers give fragrant water, which helps with headaches, coughs, worms and fevers.

Vitamin C (up to 70 mg%) provides immune protection and stabilizes the psyche, converts fat into a digestible form, reduces obesity (A. Artemova, 2000).

Biological features of the orange tree and fruits.

Orange is a perennial evergreen tree 4-12 meters high with a dense compact crown. Branches and young shoots have thorns. Leaves of medium size, pointed to the top, green, petiolate, wings are poorly developed. The leaves have glands filled with essential oil with an odor reminiscent of orange blossoms. The size of the leaves is up to 10 × 15 cm. The edges of the leaves are wavy or serrated.

Strongly scented flowers up to 5 cm in cross section. They grow singly or in clusters of 6 from the leaf axils. Their green calyces consist of 5 short lobes, 5 elongated ovoid petals, are white in color (B.Novak, B.Schultz, 2002).

Orange fruits are round or broad oval in shape. The peel is covered with dots of glands, in a ripe state yellow, green or orange, up to 5 mm thick. The white layer (albedo) is thin.

The flesh has 10-14 segments, which are firmly attached to each other and to the peel. The taste is fragrant-sweet or sour-sweet. Seeds are white, have from 2 to 12 embryos, one of them is zygote.

Orange on the Black Sea coast of the Caucasus blooms in April-May. Sometimes, during summer drought and rainy autumn, it blooms a second time (M.A. Kaptsinel, 19fifty). In the greenhouses of Krasnodar, flowering takes place in February-March. Vegetation begins at the end of January and ends in November.

Three waves of shoot growth and two waves of root growth were detected; the strongest are in May and September.

When grafted on trifoliate, the root system is placed superficially, at a depth of 10-20 cm from the soil surface. Deepening when processing more than 20 cm leads to significant damage to the root system, since 25.1-28.4% of the roots are located in the 20-30 cm layer.

Ectotrophic mycorrhiza of fungi of the class Basidio mycetes of the genus Boletud was found in greenhouse conditions. There are more actinomycetes in autumn than in spring.

There is a relationship between the number of shoots on a tree and the number of roots, that is, the better the root system is developed, the more shoots are formed on the trees.

Planting and caring for an orange tree to produce fruit.

The survival rate and development of seedlings are affected by their quality, timing and planting technique. In the open ground with a rounded crown shape, they are planted according to the scheme of 3 × 3 and 4 × 2 m. It was revealed that with a dense planting, the trees enter the fruiting season earlier, give a higher yield per unit area and better protect each other from adverse climatic conditions. When placing trees in the bush form, they give 2.5 × 2 m, and in the dwarf form - 1.5 × 2 m, or up to 3000 plants per hectare.

Standard seedlings must be well developed and free from pests and diseases. Sections must be healed.

The root system is best preserved in containers or plastic bags.

It is best to plant seedlings in open ground in spring. In protected ground, planting can continue throughout the year.

Deep tillage is carried out before planting. The root neck of the seedling after planting should be 2-4 cm below the soil level. After sedimentation of the soil, the root neck will be, as it should be, at the level of the soil. A hole is made around the seedling for watering. After abundant watering, the hole is mulched (preferably with rotted manure).

After about 15 days, when the earth in the hole has settled, check that the root collar is at the level of the soil surface.

Plants are watered every week until they are fully rooted, and when the oranges begin to grow, after 10-12 days. Watering is best done in the evening or in the morning. After watering, the soil is loosened so that there is no crust. In the fall, watering is reduced to halt growth and better prepare the plants for winter. In summer, mulching is effective, protecting the roots from strong heating.

Shading from direct sunlight promotes good growth. They use reeds, matting, burlap and other materials.

Soil care.

Care consists in its processing with the incorporation of fertilizers and green manure. When tilling the soil near the trunk, as it approaches the trunk, its depth is reduced. Surface loosening is carried out 4-5 times after watering or rains to a depth of 5-6 cm. Beans, soybeans of early ripening varieties or other green manure can be sown between rows.

How to fertilize an orange tree?

Orange most of all needs nitrogen, phosphorus, calcium and potassium.

Nitrogen plays an important role in vegetative growth, in the formation and formation of fruits. With a lack of nitrogen, the leaves lighten, and then turn yellow, the growth is weak, the fruits become smaller.

Phosphorus affects yield and fruit quality. The lack of phosphorus disrupts the metabolism - the leaves from the ends and edges are brown, dulling and bronze of old leaves are observed. The fruits are rough, have a thick peel, often ugly.

Potassium improves the frost resistance of plants and improves the quality of fruits. With a lack of potassium, the size of the leaves increases, they turn brown, the growth points die off, the fruits become smaller.

The best results are obtained by the combined application of organic (manure, compost, green manure) and mineral fertilizers. The average rate of fertilizer application is 12-35 kg per tree, with a larger amount applied under old plants. Nitrogen, phosphorus and potassium contribute 100-200 g per tree, organics - 35-40 kg each.

Formation of plants.

Crown shaping technique varies according to climate and cultivation method. In open ground conditions, with the advancement to the north, the number of trees per hectare should be increased, and the size of the crown should be reduced.

When forming a semi-bush form - in the open ground, 3-4 skeletal branches are laid in the nursery. For branches of the second order, the branches are shortened at a height of 35-40 cm. The number of shoots of the third order is not limited. Root shoots and fatty shoots are removed. Tops, if necessary, their use is shortened by half or a third of their length.

Fruit bearing trees are pruned before growth begins. Part of the branches should be shortened by a third in order to obtain increments and ramifications of higher orders.

Strongly developed trees with a height of 4 m or more are grown in areas where the absolute minimum temperature is not lower than +8°C. Here, trees do not protect against frost and up to 800 plants per hectare are planted.

At frosts down to -10 degrees, up to 1000 plants per hectare are planted, crown height is reduced to 2. 5 m. Alexandrov, 1949).

A bush crown is formed with a bole 25 cm high and 3-4 branches of the first order 30 cm long. The second order is cut to 25 cm, and the third and fourth - to 20 cm. their appearance. When tweezing, the tip of the growing shoot with 2-3 underdeveloped leaves is removed. Pinching accelerates the maturation of wood and leaves, prevents a large loss of wood during subsequent pruning and eliminates the formation of fatty shoots.

Propagation of the orange tree.

Orange reproduces by generative (seed) and vegetative means.

With seed propagation, fruiting begins only in the 7th-12th year. In addition, the signs of parental plants are poorly transmitted and individuals appear strongly prickly, with small, ugly fruits, and also vigorous. Therefore, this method is used for growing rootstocks or when breeding new varieties.

Vegetative reproduction (budding, grafting, rooting of cuttings, aerial layering) preserves the varietal characteristics of the mother plant (except for cases of bud mutation), fruiting occurs in the 2nd-3rd year of life.

Seedlings of trifoliates are used as a rootstock, and any citrus fruits are used for room culture: oranges, lemons, grapefruits, etc.

Seeds are selected immediately before sowing, since they lose their germination capacity outside the fruits. To improve germination, the seeds are subjected to stratification, for which 1 part of the seeds is taken for 3-4 parts of clean moistened sand and stored at a temperature of + 4-7 degrees.

At home and indoors, oranges are planted as follows: they are sown in any container 10-15 cm high. Holes are made in the bottom of the container to drain excess irrigation water.

Sow in a mixture of earth, manure, peat, sand in a ratio of 2:1:1:1 or in the absence of peat and manure, the amount of leaf and sod or garden soil rich in humus is increased.

Water well the day before sowing. Sow to a depth of 1-1.5 cm. The temperature of the substrate is not less than + 18 ° C. Shoots appear in 30-40 days. When the seedlings reach a height of 15 cm, they are planted according to the 5 × 5 cm scheme or one by one in milk bags, etc.

When budding, the thickness of the bole should be equal to the thickness of the pencil. A bud with a small layer of bark and wood is taken as a scion. Butt budding is the main method of propagation of all citrus crops. When grafted with a cutting, a cutting with 2-3 eyes serves as a scion.

Orange varieties for indoor and outdoor cultivation.

Now about 400 varieties of orange are cultivated, of which 20-30 are of industrial importance (T. V. Larina, 2002).

Varieties are divided into four groups (according to P.M. Zhukovsky, 1971).

Ordinary cultigen populations - fruits are spherical or oval, different sizes, multi-seeded, sweet-sour, fruitful.

  • Variety Hamlin produces small and medium-sized fruits with a round, slightly flattened shape. The skin is thin and smooth. The pulp is juicy, sweet. Cultivated in Florida, Brazil and other Latin American countries. The grade is transportable and lying.
  • Variety Salustiana - fruits are slightly flattened, with a thin skin that easily separates. The pulp is very juicy, tender, oily, melts in the mouth, sweet. Most of the time there are no seeds. The most important variety of Spain, Morocco.
  • Variety Verna (Verna) - fruits are small or medium, oval in shape. The pulp is sweet, low-seeded, fibrous, with a sweet aroma. Late variety, cultivated in Spain.
  • Navel oranges are characterized by large fruit sizes (up to 600 g, usually 200 g). The fruits have a mastoid outgrowth at the top ("navel"), formed by the overgrown base of the ovary column. The fruits are early, very tasty.
  • The Washington Navel variety has been known since 1650 and has been cultivated on an industrial scale since the 19th century in Australia and the USA, and since 1930 in the Mediterranean. The main variety in the world. Fruits weighing 170-300 g, large, often protruding navel. The peel is medium, easily separated from the pulp, orange. The pulp is dense, fragrant, sweet-sour. Fruits differ in keeping quality and transportability. The yield in greenhouses is more than 16 kg per tree, or more than 4 kg/mg.
  • Thomson Navel fruits are medium in size (150-200 g), rounded, with a small navel. The skin is thin. The fruits are inferior in taste to the Washington Navel variety - the pulp of the fruits is more fibrous and less juicy.
  • Navel Late is a late-maturing variety with softer flesh, better preservation and the same appearance as Washington Navel.
  • Spanish kinglets are distinguished by small size of trees and fruits, bright red color of the flesh and unusual taste, as well as late ripening.

Note:

Citrus against aphids and caterpillars - preparation of the solution

I collect peels from the fruits of oranges, tangerines, lemons, grapefruits. When the crusts are about 1 kg, I pass them through a meat grinder, pour the resulting mass with 3 liters of water (preferably warm). I tightly close the bottle with this mixture with a cork and put it in a warm place for 5 days.

After that, I shake the mixture well, filter it through cheesecloth and immediately bottle the liquid, cork it well again (if it is necessary to store this mixture from winter to spring, then I fill the corks with wax, or with sealing wax). I put the bottles in a cool place before use.

How do I deal with pests? For example, to kill aphids, I take 100 g of citrus infusion, dilute it in ten liters of warm water and spray the plants. Be sure to ensure that the solution gets to the bottom of the sheet.
I spray three times with a break of 5-7 days.
By the way, the solution also affects small caterpillars. I use this method regularly and it has never let me down. (A.Ivleva)

For each of us, the smell of orange and tangerine evokes a sense of celebration. Believe it or not, you can create this holiday for yourself all year round if you grow an orange tree on your windowsill.

Merkheulsky variety is most often grown in apartments: its height rarely exceeds one meter. If you try hard and be patient, you can collect from 2 to 40 fruits from one plant.

Orange tree: care at home

Orange is a tropical guest with great whims. He loves heat, so it is best to grow it in southern warm rooms.

In winter, it is desirable to place in special greenhouses for citrus fruits, but it is unlikely that a simple amateur grower has such an opportunity.

Orange is picky about the neighborhood. It is better if the following representatives of the flora are not next to him:

  • monstera;
  • hibiscus;
  • large-leaved ficuses;
  • cucumber seedlings

Lighting

The orange tree loves light. The owner must not only put it in a well-lit place, but also provide additional lighting. At the same time, it is better not to keep the plant in the open sun for a long time. There is a risk of leaf scorch.

Temperature regime

The ideal temperature is:

  • +25 degrees in summer;
  • in winter - no higher than +13 degrees, tolerates short-term drops to zero degrees.

In order for an orange to bear fruit, it must be in a room with a temperature of 15-18 degrees.

In the heat and unbearable heat above +30 buds fall, and the plant itself slows down growth.

The peculiarity of the orange tree is that in the apartment it practically does not have a period of rest. You continue to take care of him the same way you took care of him. If you send it to a balcony or a special greenhouse in winter, the plant will go into a state of deep sleep, and care for it will be reduced to a minimum.

Watering

All citrus fruits love moisture. Because of this, in no case should the soil be allowed to dry out. As soon as the earth that was scooped up at a depth of 5-10 cm does not roll into a ball, start watering. In summer, an orange is watered daily, in winter the volume and frequency are slightly reduced: once every five or ten days. It all depends on the temperature of the content.

Irrigation is carried out exclusively with well-settled water. Be sure to warm -25-30 degrees.

Oranges may not show signs of water shortage for a long time. Only in case of critical dehydration, its leaves lose their former elasticity and fall. A plant in this state can no longer be saved.

Sprays

Orange, as a representative of citrus fruits, prefers the climate of the "bath". In a word, the air humidity should be as close to 90% as possible. You need to spray the plant every day and more than once. In addition, additional water containers should be placed next to the flower pot.

If the air in the room remains dry, a special humidifier can be used.

Top dressing

When feeding an orange tree, it is important not to overdo it with nutrients. There must be balance in everything. Experienced flower growers recommend using ready-made fertilizers like Humisola.
