Thuja yellowed after winter, what to do - the main causes and methods of recovery


Going to the site in early spring, the summer resident expects to see signs of nature awakening and fresh needles of evergreen crops, but sometimes disappointment awaits him. Why did the thuja turn yellow after winter, what to do in a similar situation? How to return the plant beauty?

Needles can change their color for many reasons. Therefore, during the inspection of the thuja you need to pay attention not only to the unnatural color, but also to the condition of the conifer.

If the needles are alive, but they have changed their color to gold or bronze, or yellowing has affected only a small part of the branches inside the crown, it is possible that the thuja will recover without human intervention. And the reason for yellowing is the natural processes of renewal of the needles and changes in its color when the seasons change. But what to do in the spring, if the thuja is yellowed, its shoots have a depressed appearance, and the needles have lost elasticity, become fragile, dry?

Mass russeting, yellowing and dying off of greens on large areas is a reason to sound the alarm and take serious measures to save the plant.

Natural causes of thuja yellowing

Evergreen Thuja is called not because of the endless life of their greenery, but because of its inconspicuous turnover. The time allotted to the needles depends on the species and plant variety and is measured in 3–6 years. Then the needles lose their strength, elasticity and color, and then they fall off, giving the place to a new one.

In this case, the yellowing of the thuja goes from the trunk and skeletal branches to the outer part of the crown, it is unobtrusive and never is widespread.

Many species and varieties of thuja for the winter, though they do not lose their needles, change their color to golden, reddish-copper, bronze, and brown. The only exception is the Smaragd thuja, which, even in the most severe climatic conditions, remains emerald green.

If the thuja is yellow for natural reasons, no special measures are taken. With the advent of heat, the plant will wake up and return itself to an attractive appearance, and light sanitary pruning and nitrogen fertilizer will help it.

Why thuja turned yellow after winter: care errors

The most common cause of yellowing and deadliness of the needles in the spring is sunburn, which is not dangerous for a limited number of species. To protect the plant, to complete thawing of the crown loosely, leaving the access of air, cover non-woven material.

In regions with severe, especially snowless winters, and also a lingering spring, accompanied by thaws and sharp frosts, Tui need additional protection at this time, which will save not only from the needles burning down the decorative effect, but also from frost breeders that affect the bark and wood of the trunk and skeletal branches.

What to do if the thuja turned yellow after winter and noticeably dried up even with proper shelter?

A common cause of color change of needles experienced gardeners consider insufficient autumn-spring watering.

Left without moisture in the autumn, the hodgepipe went into the winter poorly prepared, and with the arrival of heat it is difficult for him to immediately go to growth. You can return tue beauty:

  • adjusting the mode of watering, in parallel watching, so as not to pour evergreen culture,
  • by pruning damaged branches,
  • feeding the shrub with a spring mixture of fertilizers for conifers.

An additional portion of nitrogen fertilizer and a haircut will help plants that are planted as a living wall or curb along the route, footpath, or in an area where pets are walked. Although Tui are very resistant, and they can suffer from exposure:

  • reagents designed to accelerate the melting of snow and ice
  • from intense exhaust of cars and aggressive compounds falling into the soil with melt water and heavy metal salts,
  • from systematic bowel movements and marks of cats and dogs.

Care errors can be corrected, but what if the thuja turned yellow soon after planting?

What to do when the thuja turned yellow after landing

Planted in the autumn bushes in the first spring may be covered with unsightly brown and yellow spots. What happens to the plant, and how to help it?

The most likely cause of yellowing of the thuja in the first year of life in the open field is considered an improperly planted landing.

Novice gardeners do not take into account that conifers are very negative:

  • to the proximity of groundwater, the stagnation of which causes rotting of the root system, yellowing of the needles and drying of the branches,
  • to root or neck root, which leads to growth inhibition, the risk of stem rot at the base of the stem,
  • too frequent planting of single plants, which provokes the contact of the branches, the violation of their growth, shrinkage and falling off of the needles,
  • to improperly selected, too dense, poor or saturated with water soil.

Unfortunately, if these mistakes are made, it is better to transplant, providing the plant with everything necessary for growth, including drainage, a distance of not less than a meter from the nearest neighbors and the soil consisting of turfy land with added sand and lowland peat.

Thuja turned yellow after winter, what to do, and how to determine the enemy that you have to fight?

After thawing of snow, especially on young bushes, it is possible to detect the symptoms of reproduction of harmful fungi, which parasitize not only on the surface, but also inside the tissues. Spreading in a thick crown, they cause a change in the color of the needles, drying up thin and then main shoots. In addition to microscopic fungi, tinder fungi and all kinds of rot cause damage to plants.

As a prevention of wilting and necrosis, thuja in the spring and before winter are sprayed with Bordeaux mixture or other copper-containing fungicides. In the risk zone, the treatment is repeated in summer.

Spraying is carried out after sanitary pruning and sanitation of all damages left in winter:

  • cracks on the bark
  • frost,
  • saw cuts large branches.

If there are dead, old or badly damaged plants or fungi on the site, they are removed, and the stumps uprooted and burned.

Along with pathogens, dangerous sucking insects can settle on the thuja, causing yellowing of the needles and the death of individual parts of the plant. Identify enemies will help careful study of the crown and infected areas. And to get rid of them will help systemic insecticides, which are used both for medicinal purposes and for prevention.

Why did the thuja turn yellow after winter?

There are various reasons that can trigger the loss of a beautiful appearance and the appearance of yellowed branches. In most cases, it’s all about these factors:

  1. Spring burn. If the thuja is young, then it is very sensitive to the change of season. Spring sun can cause burns.
  2. Excess moisture. When the thuja has a yellowed top after winter, this may be due to a large amount of moisture, which not only leads to yellowing, but also to the appearance of mold.
  3. A lot of fertilizer. With the introduction of a large number of additives is the burning of the roots, which causes the yellowing of the plant. Use feed is important according to the rules.
  4. Pests and diseases. With the defeat of the root system by the fungus Fusarium, the trunk and the needles become dark brown. After winter, an infection with a tuyeva spatula can occur, at which the amount of yellowness is constantly increasing.

Why do thuys turn black after winter?

On the plant after the cold you can find dark spots. There are two main reasons for this problem:

  1. If there are domestic animals on the street, yellowing may be caused by the feces of domestic animals. In this case, the spots will be in a chaotic position on the lower level. With an extensive defeat, saving Tui is practically unreal.
  2. If thuis are blackened after winter, then everything can be associated with fungal diseases. If the damage is minor, then treatment with a fungicide should be carried out. The procedure is best done twice with a break of 1-2 weeks. The affected areas must be cut off. If most of the branches have blackened, it is better to remove the thuja so that it does not become a source of infection for other plantings.

Toui turned yellow after winter - what to do?

If the plant looks unhealthy after the end of the cold, no need to rush and remove it, because the recovery process takes a long time to 2-3 years. When the thuja turned yellow after winter, but everything is on it, there are green areas, then all is not lost, and a tree can be saved. It will be important to adjust care, and also to hold special measures for recovery.

Thuja care after winter

There are certain rules concerning the care of such plants, which all gardeners should know:

  1. In February, it is recommended to cover with light material, for example, you can take a mosquito net or gauze. If burns could not be avoided, and the thuja is yellowed, then water the trees with warm water or use biostimulants.
  2. In case of stagnation of water, it is recommended to loosen the soil. If the groundwater is too high, a transplant is required.
  3. Thuis need additional feeding in the spring after winter, otherwise they will turn yellow, so it is better to choose rotted manure for this, and in the fall it should be fresh and diluted in water in a ratio of 1: 5.
  4. It is recommended to make a test for acidity, because thuja loves slightly acidic soil. If this parameter is reduced, it is better to add peat.

How to reanimate thuja after winter?

First you need to determine the cause and exclude it, otherwise any funds will be ineffective. There are simple secrets about if the thuja turned yellow after winter, what to do to save it:

  1. With the help of pruners, remove the dry ends of the branches, as the yellow needles themselves will not fall off.
  2. For treatment of infections, you can use "Fundazol", and the procedure should be done 2-3 times a week.
  3. To support the plant, cut the growth point, for example, by 3-5 cm with a small height, and if the height is from 80 cm, then by 10-15 cm.
  4. Take sour peat, which has a pH of 3-4, and mix it with the top layer of soil. It should be poured under the bushes with a thick layer.
  5. Resuscitation of a thuja after winter may include spraying after snowing with diluted “Epin”, and after ten days - “Zircon”. Another 10 days later, the treatment will be useful infusion of dry manure, for which 5 liters of water, put 0.5 st.
  6. Under adverse weather conditions, thuja is under stress, so it needs help. For example, it is possible to treat the crown with an anti-stress preparation, for example, “Zircon” mixed with the “Tsitovit” tablet. It is better to perform the procedure three times a week.

How to prepare thuja for winter?

To make the tree happy with its greenery, it is important to plant it properly and take care of it in the future. The soil must be carefully loosened, and even treated from pests and weeds. An important rule concerns the fact that the land should be suitable for acidity, and do not forget about fertilizing, which should be on time, but this is not done in winter. In addition, in order for the branches not to turn yellow, you have to cover for the winter, so the roots are covered with foliage, and the crown is closed with sacking. If the tree is tall, then it should be twisted with bundles that will protect the branches from breaking.

Tui pests

  1. Some species of ticks that settle on the needles of a tree can only be seen with a magnifying glass. If the shoots show small red insects of small size, then it can be said with confidence that the plant is affected by ticks. To get rid of pests by spraying needles "Fufanon" or "Aktellikom."
  2. The needles in the spring season may acquire a reddish-brown hue and even become covered with a grayish bloom when sucking insects, such as tuevaya aphid, tuevaya pryashnitovka, mealy worm, moth, speckle, and juniper scale attack.

In order to rid the plant of these pests, it is necessary to treat tui with Carbofos in the spring.

After that, in the summer, as a preventive measure, spray with “Rogor” or “Aktellik”. Abiga-Peak is also suitable for this purpose.

  1. Also, the plant may be subject to attacks by the larvae of a deciduous leafworm, which provoke yellowing of the needles due to the fact that they form cocoons on the shoots.
  2. Caterpillars of burlap bagworms eat greens.
  3. Weevil beetles also cause significant damage to the plant, because they gnaw and damage the bark and conifer needles.
  4. Tuva beetle, similar to fir-tree beetle, makes holes in tree trunks, which causes significant damage to the tree.

In order to get rid of these pests, should be spraying conifer in late spring - early summer. For the procedure will require drugs: "Fufanon", "Aktellik", "Confidor".

To carry out the treatment, which will allow to destroy pests, should be 2-3 times a month, observing an interval of 1 week. Spraying is best in the morning or evening. You should also be attentive to safety measures during spraying. Carry out this operation should be in a special protective suit and mask with a carbon filter.

As a feed you can use both home and commercial fertilizers. As an organic fertilizer, manure from cattle or bird droppings is used.

From the manure, you can prepare a solution for processing, it is necessary to dissolve 2 kg of manure in 10 liters of water, and then remove the resulting composition in a dark and warm place for 14 days. After that, the solution must be diluted with water again. The resulting liquid is recommended to water each tree, pouring the tool at the root


Yellowing of thuja needles can be due to several of the most serious reasons, such as: improper care of the plant, attacks of viruses and insects, natural age-related reactions. The tips presented in the article will help to cope with all the ailments from which the tree suffers.

Watch the video! Why does yellow thuja and how to save it?

Natural yellowing thuja

Sometimes the thuja becomes yellow inside. If you push the branches of pine needles, you can see this yellowing. We can say that this is the norm, because the needles change every season. Old branches, which are located inside the crown, are aging. Do not touch the dried twigs before winter, and in the spring you must manually clear the thuja from such branches. It is better not to use the tool, otherwise you can damage the plant. And any microtrauma will lead to infection.

In autumn, some types of thuja can change the color of the crown of the plant to yellow-green, and sometimes to brown-green. Therefore, if your thuja has changed color, do not panic right away. Perhaps thuja foliage or western thuja grows in your garden. In spring, when the snow melts, the soil will thaw, and in the trunk and branches of the tree sap flow will begin, the needles will again turn green. Many conifers prefer to change color, this is a kind of protective reaction of trees from the spring sun. For needles, spring burns can be devastating.

Severe frost can lead to yellowing of the needles. If the winter is not snowy and the frosts reach 30 degrees, cracks form on the trunks, on this side the needles turn yellow. It is difficult to insure against this. In regions with harsh winters, it is best to harbor thuja every year, and not only in the first year.

Other causes of yellowing of the crown

Thuja needles may turn yellow for the following reasons:

  • Over or under fertilizer.
  • Sunburn in the spring. Young thuja is very sensitive to the sun and changing weather.
  • Much or little moisture in the soil. With a lot of moisture, the top of the thuja turns yellow.
  • Diseases and pests. Yellowing can be caused by spurious shield, as well as fusarium disease.

Causes of thuja blackening after winter

After frost sometimes dark, almost black spots can be found on the thuja. There are two reasons for the problem:

  1. This may be due to infection with a fungus. If the spots are small and small, you can limit the processing of the fungicide. It is carried out twice, making a break in two weeks. The areas that the fungus had time to hit, must be removed. With the defeat of a large part of the thuja, the tree should be removed, otherwise it will infect the rest of the landing.
  2. If black spots are concentrated on the lower level of the tree, then pets that defecate on thuja are most likely to blame. If large parts of the tree are affected, the thuja will die; it must be removed.

Improper fit

Why does thuja turn yellow after planting? Novice gardeners often make mistakes when planting thuja seedlings. It is necessary not to deeply deepen the seedling, the root neck should remain at the level of the soil. When planting, it must be remembered that after several rains, the soil will settle, and the tree will sink a little more.

If the thuja suddenly began to turn yellow, you need to check how the landing site is selected correctly. Perhaps thuja grows in a damp place, or it is too dry. Drying, as well as excessive moisture, can destroy the plant.

With a lack of moisture, it is necessary to immediately water the plant, in addition to spraying. In that case, if the sun constantly falls on thuja, it needs a little shade. After that, you need the right watering, it is recommended to spray with Epin-extra.

What to do if on a site of stagnation of water? You can dig drainage grooves to drain water from the landing pit. But this is possible if the slope of the plot allows it. If it is not possible to arrange drainage grooves, arrange raised beds, which are transplanted thuja.

Fertilizer shortage

  • Для правильного развития туи нужно соблюдать баланс микро и макроэлементов. Желтизну может вызвать недостаток марганца, меди, калия или азота. When detecting yellow areas on the needles, it is necessary to make an analysis of all the additional fertilizers in order to determine whether all the elements are sufficient in these fertilizers.
  • The leaves become pale green, the shoots cease to grow, which means that the thuja lacks nitrogen. Violation of nitrogen metabolism can cause potassium deficiency. Ammonia accumulates in the crown, which causes yellowing and further death of the shoots.
  • With a lack of copper and iron, the process of photosynthesis is disturbed, the needles of the thuja lose their green color.
  • The leaves may turn yellow due to chlorosis caused by a lack of manganese.

Diseases and pests

Many pests can cause thuja shoots to turn yellow. Especially annoying plants tuevaya aphid and motley moths. When detecting the first signs of damage to thuja, it is necessary to apply insecticides.

Schutte and tracheomycous wilting sometimes lead to the death of trees. And it all begins with the yellowing of pine needles. Then it becomes gray and brown. It is necessary to destroy the plant, otherwise the spores of the fungus spread to other plants. The soil should be treated with a fungicide.

For the prevention of fungal diseases, it is necessary to spray a Bordeaux liquid in the spring. When signs of the disease are sprayed the whole garden with a frequency of 15-20 days.


If there is a spring burning, the needles turn brown. Beginning gardeners do not even immediately notice it. First, the tops of the shoots just dry out a bit. But in May, the seedlings become pronounced brown. It becomes clear that the thuja is burned. The spring sun is too bright, it begins to shine and heat when the roots of the thuja are still in frozen soil. The plant does not receive a sufficient amount of nutrient juices, as a result there is a burn.

Even shelter with spandbond and lutrasil cannot always help. Sometimes this kind of shelter only hurts, because of the lack of air, shoots start to sting up. As a preventive measure, should be thoroughly shed thuja in the fall. In the spring it is recommended to water the plant with slightly warm water, not above 40 ° C, this will help to wake up the roots of the plant.

Beautiful thuja is easy

To understand what to do, you need to know what are the rules for caring for thujas. Light, moisture, nutrition and soil structure - all of this is of paramount importance. As well as timely fight against diseases and pests. This is what you need to know and comply with in order to admire the beautiful large trees.

Light mode

  • One of the possible causes of failures in the cultivation of Tui is the decimation of the needles. This phenomenon is possible if plants are too close to each other or to the wall of a building, to the fence. This not only violates the natural ventilation, but also reduces the amount of light required for the needles.
  • The opposite reason is possible in early spring - a surplus of ultraviolet radiation and sunburns of greenery.

If there is a first reason, then it is necessary to transplant the plants, eliminating the thickening of the plantings and providing them with good natural ventilation (ventilation) and access of light.. In the second case, cover the plants. from direct sunlight or transplant in a shaded area. By the way, tui themselves feel better in places with diffused sunlight.

Thus, do not thicken the planting of conifers and avoid burns from direct sunlight, which is especially important for young plants.

Watering and nutrition

The optimum level of soil moisture is a necessary condition for the beautiful shape and color of the thuja. Why can the needles turn yellow if the watering is not followed? Both deficiency and excess moisture harm the plant. In the early spring, the stagnation of moisture entails the freezing of the root system; in the later growing season, this same phenomenon can cause the roots to rot. In cases of earthy clod blocking, it is better to transfer the thuja to another place. And continue to prevent excessive watering.

Excess fertilizer can also cause yellowing of the needles. Do not be very zealous in this matter. However, it is also necessary to know that the lack of iron in the soil causes yellowing of individual shoots. It is important to choose the optimal composition and amount of fertilizer, depending on the type of soil in your area. It will be ideal to use for planting thuja special mixtures for conifers.

Conclusion: make sure the ground is suitable enough for the thuja. on the supply of nutrients and moisture regime, and then the tree will not dry and turn yellow, and will delight you with a beautiful crown.

How to overwinter?

  • In order to avoid damage by minus temperatures, the soil under the trees is covered with leaves for the winter and the crown with sacking.
  • In the late fall, tall thuja should be twisted with bundles, which will help to protect fragile branches from breaking off into clods of snow.
  • From time to time it is necessary to shake off sticking snow, since during thaws and subsequent frosts, it can cause the formation of ice on the branches, which will lead to freezing and death of needles, which in the spring you will also see brown and ugly.

Slight yellowing of the needles is possible during the onset of winter cold. This is a seasonal and normal phenomenon and with the onset of a warmer and longer daylight day passes naturally. It is also normal to brown the needles inside the plant, from the trunk. This is caused by the natural dying off of the needles due to the outcome of their lifetime of approximately five years. At the same time, new needles are growing, hiding dead areas, so that the appearance of the plant remains quite presentable. If you don’t like individual branches, you can simply cut them off.

Compliance with agricultural machinery "care for the winter" will not worry about plants until spring. And the needles will not turn yellow from freezing.

Correct fit

Improper planting agrotechnology is another significant cause of problems with thujas. The root neck should not be either too deep or bare. It should be level with the ground. The problem of transplanting is eliminated. If the plant is planted in sandy soil, the position will also have to be changed by changing the location. For in this case, the thuja will not get enough moisture: the water will go into the deep layers of the soil. That is why in this case the plant will suffer, and you will see an ugly picture of the drying out of your pet.

Why thuja turns yellow

This is a very unpleasant problem - yellowing of the needles on the thuja. Almost all gardeners face it. The needles become brown or brown, with a yellowish tinge. Then crumble and, in the end, the tree itself may die.

But do not confuse a diseased plant from the usual change in the color of the needles. This happens in the late fall, with the onset of cold weather. Then the Tui change their color, and turn dark brown. This is a common reaction to temperature changes, colder.

There are several reasons for the needles to die off on the tui:

  • Most often, the needles change their color, getting burns under the rays of the spring sun. This happens in the first days of spring. When the snow and does not think to melt and walk along the ground even cover. The sun, at this time, is shining more and more brightly. Rays, fighting off the snow, are getting much hotter. And still not frosted from needles the needles are very tender and vulnerable. Therefore, especially at noon, there is the greatest likelihood of spring burns.
  • The second reason, no less important, is the wrongly planted tree. That is, the depth of the pit, when planting a tree was made inaccurately. Very often, without sufficient experience, the root is either too deeply buried in the ground. Or vice versa, the root neck is all above, above the ground level. This is a common mistake that everyone should be aware of and take into account when planting a thuja. Otherwise, the tree will hurt, develop poorly, and ultimately completely abyss.
  • Another reason why the thuja turns yellow is the defeat of the tree aphids. This harmful, microscopic insect sucks all the juices from it, and conifer needles as well. As a result, the needles lose their color and crumble. In some cases, the thuja dries completely.
  • Almost all coniferous plants are subject to such a disease as a fungal. And thuja is no exception. The affected leaves and twigs immediately lose their color and abundantly crumble.

What to do if the thuja turned yellow

First of all, planting this tree, you need to make sure that the hole for it dug the desired depth. The neck of the root should be located strictly on the ground level. And the root system itself when laid comfortably stowed, not wrinkled and not bent.

When disembarking a thuja from the south side, experienced growers strongly recommend pritenyat. It can be either some kind of construction, households. construction You can make your own canopy for the tree, until it is strengthened.

Secondly, thuis, especially young ones, need to be prepared for wintering. To do this, they wrap a special material. It must be bright and breathable.

Adult and strong trees withstand all the whims of the weather. But we must take into account that factor as heavy snowfall. Snow hat can break already mature branches. To avoid such injury, gardeners, armed with twine, simply tie them closer to the trunk.

Some practice, covering the spring too sunny side with spruce branches. Either construct structures that make Tenek for tuika.

If the cause is in sunburns, then in the spring and summer period, correctly watering and caring for the tree, the needles will grow new.

You can escape from fungal diseases with a base solution. It is diluted in the ratio of one bucket of water (10 liters) - add 10 grams. drug. Immediately after planting the tree is processed for the first time. Then, as a preventive measure, the procedure is regularly repeated.

If the fungus has struck the entire branch, cut it into three, see above the infected place. The section is treated with copper sulphate, 5% solution.

Early in the spring and before the onset of the first frost, thuja sprayed Bordeaux liquid. This method of treatment will help prevent the appearance of fungus.

Only wood treatment with special purchased preparations is able to escape from aphids.

How to prevent thuja diseases

Only planted tree pritenyatsya as long as it does not take root and get stronger. The soil around the thuja must be mulched. To do this, use sawdust, compost or peat. Everything is poured in a circle to the height of a matchbox, no need above. In cold weather, the root will be protected from frost. In the summer, moisture is retained longer at the roots.

Proper watering is an important procedure when growing thuja so that it does not turn yellow. Only a planted tree is watered once every seven days. Water enough 10 liters per sapling. If it is too hot outside, then it is worth watering twice a week. And so for one month.

In the summer, hot months, the tree regularly, from morning or evening, bathe, sprinkling it with a hose. But do not do this during the day, otherwise burns are guaranteed.

In dry regions, the following method is used to preserve moisture in the soil. It is necessary to take (in the ratio 1: 1) moss and earth, carefully chop everything up with a shovel and sprinkle the resulting mass around the tree.

Do not forget about dressing. After all, the lack of minerals necessarily lead to disease. The needles will fade and eventually completely crumble.

It is important to know that thuja is fed only from early spring until the end of summer. Autumn and winter can not do this. A tree begins a phase of rest, which does not need to be broken.

For dressing use purchased and domestic fertilizers. As organics used manure from cattle or bird droppings.

You need to take 10 liters of water and add 2 kg to them. manure. All this is stirred and cleaned in a dark and warm place for 14 days. After, once again diluted with water and watered at the very root, each tree. The ground around the thuja is also fertilized, and the larger the tree, the larger the diameter is treated.

Mineral fertilizers can be purchased at any specialty store. They fertilize trees three times during the spring and summer season. Often use "Idol-universal", "Appina", "Biooud".

Now you know what to do if suddenly the thuja turned yellow after winter. Be attentive to your seedlings, and they, in gratitude, will decorate your site.

Spring sunshine

One of the main causes of yellowing of thuja needles may be the spring sun, whose rays are reflected from the snow that has not yet melted, thereby increasing its intensity. Not surprisingly, the thuja, just waking from the winter cold, in the spring often gets a sunburn.

It can be saved only with the help of a covering material that will protect it from sunlight. As a covering material, you can use any burlap, spruce branches or Kraft paper.

It is advisable to cover it at the end of winter, if the covering material is not enough for the whole shrub, then the thuja can be covered only from the sunny side. But do not close it completely, it must have access to the air.

If she has already received a burn, then in this case it should be hidden in the shade and watered more often. Over time, it will necessarily increase the needles and return the original green color.

Fungal diseases

Like many plants, conifers also suffer from fungal diseases, from which their needles may turn yellow and fall off. Therefore, first of all, after planting the thuja in the soil, it must be treated with antifungal solution from the foundationol.

Ten grams of the drug is poured into a ten-liter bucket of water and mixed well. It is advisable to periodically water this solution. But it can be replaced by Bordeaux liquid.

Brown shoots

So called fungus that causes brown shoots. When a thuja is affected by this fungus, it becomes brown very quickly. In this case, it is important to notice the disease in time and immediately remove the infected branches.

Then add fertilizer at the root and sprinkle with limestone on top. After every two weeks from June to November, the entire crown of thuja should be sprayed with 0.2% “Fundazol”.

She often affects young needles, only recently planted. The needles acquire a dark brown color and the whole is covered with red dots. In this case, the affected branches need to be cut and burned. And process the plant copper-containing drugs.

In order to avoid rust in the future, it is advisable to periodically treat it with this preparation. Do not interfere with additional watering under the root "Fundazol."

This is the most dangerous fungus that completely destroys a coniferous plant. During this disease, the needles become gray, noticeably fade, and the trunk, which is most affected, becomes soft to the touch and covered with bloom.

If an unpleasant smell has appeared from the bush, then this is a signal that the fungus has already penetrated into the roots. In this case, the plant must be pulled out and destroyed. After that, the ground must be carefully treated from the disputes of the fungus, so that neighboring plants do not get sick.

Therefore, during the planting of the thuja at the bottom of the pit there must be drainage, which does not allow moisture to stagnate in the soil. To prevent thuja from being affected by this fungus, periodically it is necessary to spray it with Fundazole.

In addition to fungal diseases, tuyu, if you do not take care of it, can be attacked by insect pests, from which it can die.

In this case, you need to carefully inspect the branches and needles of the thuja with a magnifying glass, as the insects are often very small and difficult to see with the naked eye.

If several holes were found in the trunk, which become larger every day, it means that a bark beetle lives there, devouring the bark of the tree, thereby stopping the growth of the thuja. To get rid of this parasite insect, you need to carefully treat the holes with insecticidal injections.


If you find yellow-brown small insects on the underside of the needles, not more than three millimeters in length, then this is a false guard, the most dangerous pest that can destroy an entire shrub in a short time.

If they are few, then it is simply brushed off from the branches and bark with a brush. And if there are so many of them, only insecticide spraying will help. In order for the frayer in the early spring, as soon as the snow melts, do not attack the thuja, the trunk is wrapped with sacking.

Moth motley

The thuja does not feed on the mole itself, but its larvae, which it deposits in the needles. The larvae themselves are very small, do not exceed four millimeters.

It usually lays its eggs in June, so this month and July, the shrub must be sprayed with preparations containing pyrethroids, so that the motley mole does not settle on the thuja. But if the thuja has already managed to attack thuja and damage the top of the bush, then all that remains is to cut it off, and to treat the rest of the crown with the preparation.

Spider mite

If the needles were entangled in cobwebs, and small red insects run along branches and needles, it means that it was attacked by a spider mite, an incredibly prolific pest that is difficult to get rid of.

It appears on plants suffering from drought in the hot summer and sucks the last juices out of them.

Therefore, in order not to visit the spider mite, it must be watered during the hot summer. Чтобы избавиться от клеща, растение нужно опрыскать настойкой из чеснока. Но если клещ уже успел воспроизвести огромное потомство, но в этом случае помогут уже только акарициды.


If you noticed that the thuja began to hurt often and stopped growing, its branches began to dry up, look at its roots, it is likely that you will see small golden worms there. It is a wireworm that harms the roots of a bush, destroying its immunity.

To get rid of the wireworm, in late autumn you need to dig the soil around the plant, drain and deoxidize the ground. If there is a lot of wireworm, then it is mixed into the soil with products containing diazinon.

If numerous small gray-brown insects have been found on the shoots, then this is an aphid that loves to eat the sap of the tree, bringing it to a state of drying.

If the aphids are not very much, then you can get rid of it by washing the needles with soap. This should be done weekly, covering the soil with a waterproof film so that the soap solution does not penetrate the roots.

If there are a lot of pests that even washing does not help, then spraying the shrub with any insecticide will help get rid of them.

So that no pests want to settle on your tui, in the end of spring, as soon as the snow has come down, it is advisable to spray the hvoynik with “Fufanon”.

Repeat spraying should be twice a month until late autumn. In the hot summer it is better to spray early in the morning or late in the evening. And do not forget during the spraying to don a protective suit and cover your face with a protective mask.

Planting and care

Many novice gardeners make the same mistake in planting a thuja, placing its basal neck too deep in the ground or leaving it in the fresh air. And they even forget about the drainage at the bottom of the pit. Because of this, the immunity of the coniferous bush falls, and its roots are affected by rot.

And it is also undesirable to plant thuja near groundwater, as its roots will rot, this will lead to shrinkage and the extinction of the branches. Thuja is not a moisture-loving plant.

Tuyu is not recommended to plant too close to each other, as they will touch the branches and feel cramped, and therefore can stop their own growth and throw off the needles. The distance between them must be at least a meter.

The soil for planting should not be too dense, acidic, moist, poor in minerals. The soil should consist of turf land with the addition of peat.

If the above errors were made, then it is better to transplant a coniferous plant to a better place and do not forget about drainage. The first time after transplanting it is better to shelter it from the scorching sun, in order to allow the plant to quietly adapt to a new place.

And be sure to ground around her zamulchirovat sawdust or peat. It is watered once a week during the first month, and then less frequently.
