While cold hardy palms can tolerate freezing temperatures, tropical palms may suffer from the cold damage. Usually, palm tree owners, that live in the warm climates, don’t need to worry about cold weather.

But, with unpredictable winters in the last couple of years, freezing temperatures don’t come as a surprise. Here is what you can do to protect your palm trees from freezing cold by applying:

  1. Palm fertilization
  2. Palm heavy mulching
  3. Palm heavy watering
  4. Antitranspirant spraying
  5. Copper fungicide spraying
  6. Palm warm cover
  7. Palm trunk and foliage wrapping
  8. Heater and light-bulbs
  9. Heat cables
  10. Temporary greenhouse

How Does Cold Affect Palm Trees

Cold weather can affect palm trees in different ways. Cold temperatures will slow down the root activity and growth rate of the palm.

Freeze or frost can damage the palm tissue in the trunk, which may limit the ability of the palm to provide leaves with enough water. Unfortunately, palm trees can’t regenerate conducting tissue and will likely die after a while. If the bud, also called “palm heart”, gets damaged, the palm will not survive.

How Cold Is Too Cold For Palm Trees

Palm species very greatly in their sensitivity to cold. Some types of palms can tolerate cold temperatures down to 10 – 15F for a short period of time, while others gets damaged when the temperatures drop below 45F.

Cold tolerance of the palm also depends on summer care, plant age, and time of establishment. If you are trying to figure out what is the lowest temperature your palm can survive at, start by checking cold tolerant for this particular species.

You can find it in my palm tree catalog under ‘Cold Hardiness’ section in the palm profile. Keep in mind, that by providing winter protection, you can push a palm’s tolerance by one-half or full USDA zones which means a range of 20 – 30F (12-18C) for subtropical and temperate plants.

10 Ways To Protect Palm Trees From Winter Freeze, Cold, or Frost

Before we talk about different cold protection options, it’s important to understand that a little bit of cold weather is actually good for the palms, because it promotes dormancy and also makes palms more cold tolerant (cold hardy). So, don’t start winterizing your palms too soon.

If there is no sudden temperature drop, let the palms acclimatize a little to the colder conditions. The goal is to protect the most important part of the palm which is the bud and to minimize the damage to the leaves and stems in case of an unexpected freeze.

Thankfully, there are number of things you can do to prepare and protect your palm tree during winter. Some of them are very simple while others are more complex. It’s good to know that even the simplest measures can add one-half to a full USDA zone to your garden.

1. Palm Fertilization

Palm tissue deficient in nutrients is less cold tolerant. Thus, it is important for the palm tree to receive right amount of fertilizer in the months leading up to the period of cold weather.

According to recent studies from University of Florida, fertilization improves cold hardiness of palms. Of course, the fertilization schedule will depend on where you live and the length of your growing season.

If you live in a climate with cold winters, the key is not to apply fertilizer late in the growing season, since the palms will continue to grow into the early winter. That will delay the dormancy and open them to more cold damage.

I recommend using a slow-release good quality fertilizer that has the same amount or close of Nitrogen (N) and Potassium (K). You will know the ratio by looking at the three numbers on the label (NPK): 15-5-15 or 20-15-15. Avoid using lawn fertilizer with ratio of 27-2-2 because it will promote foliar growth instead of root and flower development.

You can see what top 10 fertilizers I recommend in my palm tree fertilization post.

2. Palm Heavy Mulching

Heavy mulching is the most effective way to minimize leaf damage and maximizing tree survival.

You are probably already applying mulch all year round, but during winter mulch your palm more heavily. Adding 4-6 inches of mulch will protect ground from freezing deeply, thus protecting roots and lower trunk of the tree.

Since a lot of cold tolerant palms have their buds underground, mulch will keep the temperatures relatively constant protecting it from cold damage caused by rapid temperature fluctuations.

Also, unfrozen roots will be able to replenish the moister lost during winter transpiration. I recommend using organic mulch like course wood chips, maple or oak leaves, wheat straw or pine straw because they don’t compact too much over winter and moderate soil temperatures, suppress weeds, conserves moisture, and add nutrients to the soil as they decompose.

Another benefit of using whole deciduous tree leaves with the mulch, is that they release considerable amount of heat while decomposing. To keep the mulch from blowing away you can use a wire netting enclosure. Put the mulch 1-2 ft away from the trunk of a small palm and about 3-4 ft away from a large tree.

You should leave the mulch until your area is done with the frost and then gradually remove it over a period of a 3-4 days. Removing it slowly will provide your palm with more time to get used to increasingly stronger sunlight and also provide some protection against a late frost.

3. Palm Heavy Watering

While mulching will prevent roots from freezing, it won’t help with the water uptake that gets dramatically reduced once the temperatures falls below 40°F (5°C). Adding to the stress, cold winter winds in combination with the afternoon sun cause winterburn and defoliation of the palm.

To maximize water availability to the leaves, make sure the palm is well-watered entering winter season and the soil is saturated throughout the winter.

Since moist soil loses heat less rapidly than dry soil, water heavily the soil around the palm prior to a cold snap. I recommend using lukewarm water instead of a cold one because it will somewhat warm up the ground increasing the water uptake of the palm.

4. Antitranspirant Spray

Another way to reduce water loss from the leaves is to use antitranspirant spray. It forms a soft, clear, flexible film on the plant’s foliage which holds moisture reducing water loss during plant stress. I like spray called ‘Wilt Stop’ by Bonide.

I use it for winter protection or to minimize a transplant shock if I am transplanting a palm during growing season. It protects plants from drought, wind burn, sunscald, winter kill, transplant shock, and salt damage while at the same time allowing them to grow naturally.

You will only need to spray it once per season. BTW, it will also extend the life of Christmas tree by preventing it from drying out too quickly.

5. Copper Fungicide Spray

Stressed by cold temperatures, palm trees can become vulnerable to bacterial and fungal infections. The low levels of bacteria present on healthy palm tissue are harmless but becomes a problem once the palm has been damaged by cold.

That is why it is a good idea to spray the tree with fungicidal copper before the freezing temperatures in order to reduced the amount of bacteria to the lowest levels possible.

Spray the stem and foliage with a broad-spectrum fungicide/bactericide like Liquid Copper Fungicide by Southern Ag a few days in advance when you are expecting cold weather. It has a unique formula that helps fight both bacteria and fungi.

You should also spray open-crowned palms, because water collected in those crowns might freeze and thaw causing the damage to the tissues and providing perfect conditions for bacteria and fungi.

6. Warm Cover

During cold days, it is a good idea to cover your palm. If your palm tree is small, you can cover it with a weighted down box or a blanket. On sunny days, partially open a box to avoid air heating up to damaging temperatures inside.

This can happen even with the outside temperatures being below freezing. Don’t let the tree sit under the cover for more than 3 days in a row. After 3 days, uncover your palm during the day to provide it with some light.

For a larger palm, use a blanket, burlap or other warm material. Avoid using water-absorben cotton type of materials since they trap moisture resulting in the trunk rot.

When placing the blanket over the tree, allow for the cover to drape loosely so that warm air rising from the soil will be trapped under the cover. This will keep your palm 4-5 degrees warmer than the outside air.

You should remove all the covers once the weather is warm again. Avoid using a plastic for covering, as it may traps moisture underneath that will freeze and cause more damage.

7. Palm Trunk and Foliage Wrapping

Trunk and foliage wrapping is another great palm winterizing technique if you have a palm with a central trunk. Again, it’s best to use a material that does NOT absorb moister like synthetic blanket, burlap or a landscape fabric.

Before wrapping the tree, spray the area being wrapped with fungicide/bactericide spray like Liquid Copper Fungicide by Southern Ag.

Next, wrap the material around the trunk and secure it with a duck tape. Continue to wrap up around the lower leaves while gathering the leaves closer and closer into a bunch. Wrap as high as the stiffness of the leaves will allow it. Don’t worry, the foliage is not going to be damaged.

You can usually wrap the whole foliage mass of a smaller palm tree covering it completely. At this point, your palm might look like a mummy. During extreme weather, you can easily drape a cover over the open foliage on the larger palms removing it once the cold has passed.

While you can apply multiple layers, even one layer adds 2°-3°F (1-2C). Multiple layers of synthetic blanket can even add a full USDA zone of protection keeping the temperatures under the wrap 6°-8°F (4°-5°C) degrees warmer than the outside.

Some gardeners use bubble wrap, but I don’t like it because it might cause condensation that will lead to some problems.

Expert Advice: To minimize the fungal and bacterial problems, place sticks around the trunk before wrapping it so that the wrap does not touch the trunk.

It is safe to leave the wrap on until early spring.

8. Heater and Light Bulbs

Another way to warm up your palm, is to place a small propane heater near the palm and use a fan to blow the warm air towards it. Keep the heater far enough from the tree to prevent overheating or burning.

Perhaps even more effective way, is to winterize your palm tree with Christmas lights. Simply wrap them around trunk a little denser than normal. As long as there is no wind, the lights will add 2°-3°F (1-2C) during cold winter night. In windy conditions the heat disappears too quickly to provide any warmth.

Using holiday lights underneath a loose landscape fabric, can add another 2°-3°F (1°-2°C) of heat. Some palm enthusiasts use the holiday lights underneath the wrap easily adding 10°-15°F (6°-9°C). While this sound like the best solution, it might dry up the tender leaves.

Expert Advice: Be careful with the light bulbs if you are relying on snow as your cover. The lights can melt the snow around the palm leaving it fully exposed to freezing air and cold winds.

9. Heat Cables

Another popular palm winterizing technique is the usage of the low-wattage heat cables. Typically used to wrap water pipes to prevent freeze damage, heat cables can be found in any of the hardware stores. Just like the holiday lights, they can be used around the trunk and the foliage of the palm.

The cool thing about heat cables is that they are extremely safe and reliable and most of them come with a built-in thermostat that automatically turns the heating cable on below 40°F and off above 55°F.

Some gardeners also use heating cables to wrap around the root ball when planting a palm. Then, they can active it during a cold winter to heat the root zone and prevent the roots from freezing.

Additionally, this warms up the water and as a result provides supplementary heating to the above ground plant tissues when the water moves up the roots system.

10. Temporary Greenhouse

If you have a lot of time and energy, you can build a temporary greenhouse around your palm. Adding a supplementary heat to the greenhouse will add two or even more full USDA zones to your garden.

This is the most involved method that will allow you to grow palm trees almost anywhere. Of course, the greenhouse structure has to be strong enough to withstand strong winds, freezing rain and heavy snow.

Built a wooden frame above the tree and cover it with double plastic sheet nailing it to the frame. Wet snow is very heavy, so make sure to built a slanted roof.

Conclusion

If I see a cold weather coming my way, I usually use heavy mulching, saturate root area with water, spray tree with broad-spectrum fungicide/bactericide and apply Christmas lights.

If the cold weather is going to last for a few days, I use antitranspirant spray and a wrap under Christmas lights. That’s usually enough. Since I live in a warm climate, I really don’t need more advanced winterization techniques.

I hope my tips will help you prepare your palm trees for cold weather. Let me know if you have any questions.

What to Do About Palm Freeze Damage (and How to Protect Palms) | Davey Blog

We’re used to seeing palm trees flowing carefree in a breeze with a golden sun and blue skies as their backdrop.

But in some areas, palms don’t get to soak up paradise all year round. Take Florida, for example. Allison, a Davey blog reader from the northern half of the state, reached out for help with her freeze damaged palm trees. She said, “we had a hard freeze in Florida and our medium palms took quite a hit. I don't know if I should prune them down to nothing or let them be. I also don't know if they are still alive.”

Harsh winter weather can be tough on these tropical trees. Read on to learn how to help them bounce back.

How to Help Freeze Damaged Palms and Protect Palms from Freezes

With careful prep before and lots of patience after, some palm trees can survive a wicked-cold winter.

A cold freeze looks like it damaged my palm (areca, sabal, pindo, pygmy date, and coconut). What happened?

A visit from Jack Frost will have palm trees switch from leafy green to rusty brown before your eyes. Why is that?

Well, unlike hardwood trees that sprout new growth from multiple spots, palm trees only grow new leaves from one spot—the heart. The palm heart sits right in the center of the tree’s canopy, and if it’s hit with harsh cold, the damage trickles down to all the future palm leaves growing from it.

Plus, if a palm is planted outside of its growing zone, it’ll be extra vulnerable to cold damage. For example, pygmy date palms are meant for planting zones 9-11, areas that get almost no frost. That means they wouldn’t do so well in Allison’s neck of the woods in Northern Florida. The same goes for areca and coconut palms—frost can be fatal for these quintessential tropical trees.

But even if palm trees are tolerant to the cold (like pindo and sabal palms, which can bear 15- and 20-degree temperatures) a hard freeze can still spell trouble. No matter the type, always err on the side of caution with your palm trees. It’s really important to protect all palm trees whenever harsh winter weather is expected.

How can I tell if my cold damaged palm trees are alive?

By far, the best way to determine the health of your tree is to get an arborist’s opinion. In the meantime, here are a few things to consider:

  • Your tree needs time. It’s really hard to predict the future of a freeze damaged palm. Most palms won’t show any new growth for months after the damage was done, so patience is the best gift you can give your recovering tree.
  • Green is good. Even if leaves are mostly brown, any sign of green could mean the tree has a chance at survival.
  • Let nature take its course. Let your palm tree handle the healing process on its own. You may remove fronds that are completely brown to improve aesthetics.

How can I protect palm trees from freezes in the future?

Palms have a much better chance at surviving a winter freeze with these preventative steps:

  • Always plant palms that are suitable for your area. Find out what your planting zone is here!
  • Carefully cover short palm trees with a blanket or sheet before an expected freeze. For taller palms, contact an arborist to wrap the fronds together to protect the heart. Remove the sheet and unwrap the fronds after the threat of freeze.
  • Before a freeze, water your palm tree deeply, and seal in the moisture with mulch.
  • Keep your tree on a regular fertilization schedule. The nutrients in fertilizer may help support cold tolerance by improving tree vitality.

Frost not afraid? How a Krasnodar citizen grows palm trees in the open air | LEISURE AND REST

Alexander Vlasenko

Estimated reading time: 10 minutes

Palm trees feel great in the summer under the Kuban sun, but, as it turns out, they can withstand frost. / Anatoly Marchenko / From the personal archive

Anatoly Marchenko became interested in palm trees about seven years ago. He was very impressed by a beautiful photograph he saw on the Internet of someone's yard planted with these exotic plants. Although that picture was taken in warmer climes, the man got the idea to grow something similar at his home in Krasnodar. He was encouraged that by that time palm trees had been successfully growing in the ground at the entrance to one of the city's shopping and entertainment centers for several years. And the World Wide Web has confirmed that if you want to create the same beauty in your garden, anyone can, and not only a resident of the south of Russia.

Cold is not a hindrance

“There is a lot of information on this topic on the Internet, especially in English,” says Anatoly Marchenko. - It turned out that even in a cold climate, many types of palm trees can be grown outdoors. For example, they grow outdoors in the northern US state of Utah and in Stockholm, where it is much colder than Krasnodar. I started reading forums, delving into different nuances, and eventually did the same for myself.”

He started by planting five different kinds of subtropical palm trees in his dacha. Such a scatter was required primarily for the experiment. The goal was to check how each of the plants will show itself, because in any business there are difficulties in the transition from theory to practice. Anatoly Marchenko does not hide the fact that only one of those five palm trees has survived to this day, while the rest died for various reasons. But now he knows exactly what to do and how to do it. Now exotic beauties grow without problems not only in his country house, but also at work. The man admits that he planted three palm trees near the gas station in Khadyzhensk in order to attract the attention of motorists.

Choice in favor of locals

Ideally, it is better to take up this business following the example of Anatoly Marchenko, that is, having previously studied the issue. But for the first steps, the basics that he shared should be enough.

Start by choosing plants. According to the man, most palms that grow in the subtropics (not to be confused with the tropics) are suitable for central and southern Russia. For example, he himself grew species such as trachycarpus fortune, small sabal, squat chamerops, butia, washingtonia. Their advantage is the ability to withstand frost for a short time. The record holder for this indicator is the porcupine palm, which tolerates up to minus 30 degrees. But still, it’s better not to risk it, because hypothermia can spoil the appearance of even a “hardened” palm tree. In addition, much depends on the condition of a particular plant.

“It is important where it came from,” explains Anatoly Marchenko. - For example, palm trees from Europe are weaker than those grown in Sochi. We still have quite an extreme climate for them, so they are more hardened and adapted. I mainly bought local palms, although I also have one Italian that also fits. She spent the winter in Sochi and withstood minus 13 degrees. At the same time, she had normal leaves, while other similar palms had all of them burnt. That is, there are many nuances and you always need to look, choose.

He also emphasizes that the age of the plant is of great importance. If the palm tree is very young, then one should not expect special frost resistance from it, no matter what species it belongs to. Therefore, given the fact that they do not grow quickly, it is better to take larger and older specimens.

Agrofibre - the key to success

According to Anatoly Marchenko, in Krasnodar adult palm trees of the most frost-resistant species are able to survive some winters without protection at all, because severe frosts do not happen often in the city. But it is unlikely that with this approach, these plants will retain a beautiful appearance for a long time, for which they are needed. That is, in order for a street palm tree to please the eye, you must always cover it for the winter. To do this, first of all, you need a special material that works on the principle of sportswear.

“There is no ready-made recipe for this,” continues Anatoly Marchenko. - For example, in one place you need to take into account the wind, in another - the rain. But in any case, ninety percent of success is the material. It is necessary to use agrofibre with a density of at least sixty. It removes moisture so that the plant does not rot, and at the same time retains heat. But the use of cellophane is a 100% way to death. Under it, on warm sunny days, the plant fades, as if under a magnifying glass. And if frost hits later, then everything that is rotten will freeze. Cellophane is definitely not suitable.

Before wintering, the leaves of the plant must be tied together and wrapped at least twice with agrofibre. You will also need to make a tent from this material to the size of a palm tree, the base of which can be knocked down from boards. Since the agrofibre gradually passes water, the structure must be covered from above with oilcloth from rain. For a greater insulating effect, the box is dug in with earth from below, and it is recommended to pour sawdust, straw or leaves higher around it. There are various other little tricks that make the wintering of the plant much easier.

Anatoly Marchenko recommends filling the winter "houses" of palm trees with five-liter bottles of water. Their number is selected depending on the size of the plant, but in principle, the more the better. Water helps create a more even microclimate inside the box. When it freezes, it gives off a lot of heat, and when it melts, on the contrary, it takes away its excess. If you paint the container black, the effect will be even stronger. But you don’t need to put everything directly on the ground, so as not to interfere with the rise of heat from it. The ideal option is to hang the bottles inside the box.

"Stove" from a light bulb

For Krasnodar, the described methods of insulation in most cases are enough. But even in the south, they may not be enough when the plant is young or if it is not among the very frost-resistant, like the same date palm. In this scenario, you will need to make a heating system. Anatoly Marchenko uses an old-fashioned luminous ribbon made on the basis of ordinary light bulbs for this. It fits perfectly, but it's no longer being made, so other people will have to look for alternatives.

“An American who grows palm trees in an almost arctic climate uses ordinary 100-watt light bulbs for heating,” says Anatoly Marchenko. - I think one lamp per plant is enough. And it needs a regulator to prevent overheating. For this, a thermostat of underfloor heating is suitable, which is set to a temperature of 7-10 degrees. It's not very convenient with light bulbs, but so far I don't see any other alternative, because everything else will overheat. To anyone who wants to make such heating, I want to remind you of the safety measures. In humid conditions, you have to be very careful with electricity.”

He himself now grows six palms: three are in his dacha and the same number at work. Plus, for several years he has been voluntarily helping to save palm trees in the Aurora cinema from death, which are in danger due to the repair of the building. Moreover, a man easily copes with such a number of "wards". Since everything has already been debugged for him (in addition to automatic heating, there is also automatic watering), then you need to make efforts only twice a year: to cover the plants in winter and open them in spring. Anatoly Marchenko hopes that the dissemination of this information will help make not only people's backyards more beautiful, but cities as well. At least, in his opinion, it would be quite possible to plant a whole palm alley in Krasnodar.

how to save her? Why do palm leaves dry.

If suddenly the leaves of a palm tree growing in the house begin to turn yellow and dry, there is no need to panic - you just need to think about how to revive the palm tree. To do this is quite simple. Such a symptom of "illness" can appear with a lack of moisture, or with very dry air. Therefore, you need to cut the leaves, a little higher than the dry part of the leaf, then wash each leaf with water (if it is winter) or spray with water (if it is summer). And yet do not forget about the regular watering of the plant.

Even children know what a date palm looks like. This is the best among ornamental plants because of the evergreen sprawling crown at the top. Under natural conditions, it reaches a height of 10 to 30 m. Its straight trunk is distinguished by “shaggyness”. However, at home, the height of the palm tree is 2-2.5 m. Do not forget that the palm tree is a southern plant, which means it loves heat, light and moisture. Providing all this at home is troublesome, but possible (although, of course, a greenhouse will be an ideal place for a palm tree).

If you don't know how to prune a palm tree, you can ruin it. The fact is that at the “home” palm tree you cannot cut its beautiful spreading leaves. Then she will lose her luxurious decorative appearance, and in the places of the incision, the plant may begin to “sick”. The only thing that can be pruned is the roots of the plant during its transplantation, which must be done annually until the palm tree reaches its five years of age. When a palm tree is older than five years, all its roots need is space, so the tub must be large enough.

If you wish, you can plant a date palm in your home. How to grow a date palm at home? Remembering that the palm plant is large, you need to take care of a high pot in advance. When transplanting a palm tree to the bottom of the pot, it is advisable to lay a layer of drainage for gradual replenishment with moisture. The roots themselves must be planted exactly at the depth to which it was planted before transplantation, otherwise the roots will rot. Although the date palm loves warmth, at home it is not picky, and it has enough temperature from +18 to +220C.

Fans of exotic plants should remember that, for example, a mixed palm tree is very capricious - how to care for it, so it will grow. Abundantly, but rarely it needs to be watered in spring and summer. In winter, the “golden mean” should be observed, that is, not often, but do not forget about watering. As with other types of palms, you need to remember that the leaves cannot be cut, since this is where the growing point of the palm is located. Growing a palm tree at home, you can get positive emotions not only for yourself, but also to please your friends and relatives.

The brown ends of the leaves of a palm tree are the result of excessive dryness of the air and improper watering (overdrying or waterlogging) earthy coma. In summer, the palm tree is watered abundantly, avoiding stagnation. moisture (it is impossible for water to get into the "heart" of the plant - it will rot and the palm tree will die), wash the leaves with water from pests and drying, sprayed. If the room temperature is higher 16-18 degrees, palm spraying should be done daily. In winter, watering palm trees is reduced, so how they need a period of relative rest (from November to February) and slow down (or completely stop) growth.
Now regularly spray the palm tree alternately: with water with the addition of "Epin" and horsetail decoction. Sometimes use horsetail broth also for watering palm trees, adding it to the watering water - it is rich in silicic acid, which palm trees love. If there are no leaves on the palm tree, build a "mini-greenhouse" in a pot to create microclimate for its roots and onion-shaped thickened shoot with a vegetative cone, from which new leaves develop; ventilate the greenhouse regularly.
In winter, protect the palm roots from the cold. At the end of the dormant period, transplant the palm into a new one. deep (since the roots of palm trees are long) pot with drainage, preparing the substrate from equal parts turf, leaf, peat land, humus and sand (for adult palms, add to this mixture clay). When transplanting, remove dead roots by sprinkling cuts with charcoal; healthy roots are not cut - put them in a pot "ring". After the appearance of new leaves, start fertilizer, feeding palm trees in spring, summer and half of autumn (from March to October), alternating mineral and organic fertilizers.
Keep the palm in the light (but keep out of the sun) or in partial shade. Loosen the top layer regularly soil without touching the roots; protect from drafts. Dried or damaged palm leaves can be removed only when the petiole of the leaf dries up - otherwise the nearby ones will begin to dry out leaves.

Horsetail tea concentrate recipe : 30 g dried horsetail (buy at the pharmacy) pour 1 liter water and leave for a day, then cook for half an hour and strain after cooling; before use dilute 1:5. This decoction is also effective for spraying indoor plants against mealy dew.

Why do the tips of the date palm dry out? Why do spots appear? Date palm ailments can be associated with both diseases and illiterate care .

Fungal and viral diseases

Various pathogens are responsible for date palm diseases :

  1. Fungi.
  2. Viruses.
  3. Bacteria.

Among fungal diseases, the most common gray spot . Signs of the disease are gray spots on the leaves, more on older ones. As the disease develops, black blotches appear - these are spores of the fungus.

For treatment it is necessary to remove all infected parts until the disease has affected the entire plant. Next, the palm is treated with fungicides - special antifungal drugs. The same remedies are applicable for another, no less common fungal disease - pink rot.

Bacteria lead to putrefactive processes. They are characterized by the softness of the stem and leaves, which also discolor and fall off. The appearance of bacteria is facilitated by increased soil moisture and keeping in a cold room.

If a mosaic type pattern appears on the leaves, this indicates a viral infection. Most often, plant is infected by insects. , which must be destroyed indoors in time. They can be:

  • flies;
  • mosquitoes;
  • moths.

And other insects that can enter the premises. Mosquito nets should be placed on windows for protection.

Every six months it is necessary to carry out preventive treatment of plants with special chemicals.

Causes of loss of decorative appearance

Soil oversaturated with moisture can lead to brown spots on leaves . Watering with cold water leads to the same result.

Barrel softening , in combination with a putrid smell, also signals an excess of moisture that threatens the life of the plant.

To check, take it out of the pot and inspect it. If dead roots are found, separate them from the living ones and clean them thoroughly. Transplant into another pot and into drier soil.

Date palm leaves are drying, what should I do? If watering is insufficient, the leaves begin to wither and turn yellow. . It may also be due to poor-quality water - too hard or low in essential trace elements.

But the same symptoms can also indicate too dense soil, and associated moisture stagnation. The best solution in such a situation would be to transplant into looser soil.

Brown discoloration of leaf tips - the result of insufficient air humidity. The same symptom is characteristic of hypothermia.

Red spider mite is one of the main enemies not only of the date palm, but also of many other indoor plants.

The size of the insect is only half a millimeter. It is bred in rooms with extremely low humidity and high temperature. Starts first in the stem, gradually spreading to the leaves.

Symptoms are gray or yellow spots and cracks. If you do not take action, the green pet will die, completely covered with cobwebs. Particular attention should be paid to the spring, this is the time of the most likely infection.

Shield also feeds on plant sap and spreads very quickly. Insects gradually cover the entire palm tree, its surface becomes like the smallest scales. As a result of the loss of juice, the foliage withers and turns yellow, the shoots may dry out.

  • phosphamide;
  • fitoverm;
  • actellik;
  • pyrethrum.

The proportion of the chemical solution is 2 g per 1 liter. water. Spraying is advisable to carry out once a week.

Traditional disinfection is also suitable: wipe the infected areas with a cotton swab dipped in alcohol and spray the rest of the plant.

For health and freshness

How to rejuvenate the date palm? The renewal of the date palm consists in the constant renewal of leaves that appear from above and die from below. Need to delete withering or withered lower branches .

Top branches cannot be cut ! This can lead to the death of the plant. The drying of the upper branch is an unnatural process and signals a disease.

Proper care is a panacea for many diseases

Weakened plants deprived of competent care are most susceptible to diseases. Compliance with all rules :

  • irrigation;
  • top dressing;
  • temperature;
  • light mode;

can prevent many diseases.

The plant should be inspected regularly, and if pests are found, they should be destroyed immediately.

Many growers wonder. Why do palm leaves dry? Let's try to figure it out.

Drying of the tips of the leaves in palm trees most often occurs from too dry air, insufficient watering. And they die entirely, if they are very old, from rotting of the roots during overflows or from damage by various pests and pathogens.

Yellowed leaf tips should be cut off. However, this should be done without affecting the living green tissue of the leaf and leaving a thin strip of dry tissue, otherwise the drying will go even faster and the leaf can be lost. Only completely dry leaves are removed, otherwise others will begin to dry.

Much depends on what light and temperature conditions your plants are in, how you care for them, because some fan palms need coolness in winter.

  • Warm room palm trees - areca, coconut, cariota, hamedorea, acanthophenix, phoenix Robelini - require high room temperature and air humidity.
  • temperate indoor palms - hovei (Belmora, Forstera), Bonneti coconut, geonoma, clinostigma, rapalostylis, rapis, sabal, etc.
  • Cool room palms - chamerops, brachea, washingtonia, trachycarpus, etc.

Palm tree in a pot

In room conditions, palm trees need regular spraying, proper watering, in which the earthen ball should be evenly moistened, which is determined by tapping the pot with clicks from the bottom up. A dull sound appears when the soil is wet, sharp when it is dry. After watering, water should be poured into the pan, which will soak into the ground within an hour. It must be drained or picked up with a clean rag. It should be watered with settled water after the soil on top of the pot dries.

Tropical palms require moderate to warm rooms during the winter. Palm trees, whose homeland is subtropics, are best kept in cool rooms in winter. All palm trees do not tolerate drafts, especially you need to be wary of cold air when ventilating a room in winter through a window. Palm roots are very sensitive to cold, so do not place palm pots on a cold window sill or marble floor slabs.

Plants need regular (twice a month in summer and once in winter) feeding with a special liquid palm fertilizer. Examine the bottom of your palm trees: have their roots come out and are the roots pushing the soil out of the pot from above? Then they need to be transplanted into larger flowerpots with a fresh potting mix recommended specifically for palm trees.

Ventilation
  • On a frosty day, keep the windows wide open in the plant room. Note also that in most cases, frosty air is dry. Therefore, ventilation does not increase the humidity in the room. It is best to ventilate more often, but little by little.
    • Tip : At approx. 0 °C, it is enough to open windows for 10 minutes every 2-3 hours.
  • Optimal temperatures: 20°C in the living room, 16-18°C in the kitchen and bedroom.
    • Tip : If possible, regulate the temperature in the house not by ventilation, but by using a thermostat.
Natural moisture evaporation
  • Hang wet towels on radiators or place bowls and other open containers filled with water next to them. Tropical aquatic plants in miniature vases and bowls will additionally humidify the air.
    • Tip : Wash glass vases frequently to prevent algae from growing on the walls.
  • Indoor fountain - more than just a decorative piece of furniture. The sound of gently splashing water calms the nervous system and relieves stress. At the same time, moving, slowly evaporating water has a positive effect on the state of the air. The smallest dust particles are moistened, become heavier and gradually fall to the floor.
    • Tip : Fountains with containers for planting are available for sale. Essential oil can be added to the fountain water.
  • Give pleasure to plants that need high humidity, such as arrowroot: put it on constantly moistened claydite or small pebbles. Evaporating moisture will rise directly to the leaves.
    • Tip : Place a water level indicator in the pot, then the roots will not suffer from dampness, and the aerial part of the plant from dryness.
Green Humidifiers
  • Cyperus is unrivaled among indoor plants: depending on its size, it releases from 500 ml to 2 liters of moisture into the air per day. For such records, place a bowl filled with water next to it and spray its leaves daily.
    • Tip : Even better, put several plants side by side.
  • Delicate, like velvet, light green leaves of room sticky, or Sparmannia, which grows to the ceiling in suitable conditions, evaporate moisture all year round. Spray the top and bottom of the sparmania daily with settled water. In winter, water very moderately, after making sure that the plant needs watering.
    • Tip : Be careful if you have allergies. In this case, try not to touch the Sparmannia leaves.
Electric humidifier
  • A variety of models are available with a wide range of prices. They evaporate, atomize and spray moisture or distribute it evenly throughout the room by ventilating.
Plant spraying
  • In a heated room, spray the leaves of green plants every morning. It does not take much time, but brings wonderful results. A gentle shower refreshes the plants, allowing their cells to work at full strength, and in addition increases the humidity in the room.
    • Tip : For spraying, boil water in a large pot and reserve it in large plastic bottles.
Humidity measurement
  • A hygrometer installed in every room of the house will let you know exactly how humid or dry the air is. Digital thermo-hygrometers also show air temperature and time (see photo on the left).
    • Tip : It's very easy to check the humidity level with a pine cone. With excessively dry air, its scales open, with excessively moist air, they close.
