Juniper turns yellow, what to do?
There are many varieties of juniper. All of them were created specifically for decorating the garden. Juniper is always green. It never fades and remains beautiful for many years, which greatly adorns the territory. He also does not require special care and rarely gets sick. Only sometimes the juniper turns yellow. And the beauty of the site is not the same as it was before. Juniper turns yellow: what to do and why is this happening? There are several reasons for this process, which we will analyze.
Is it normal for juniper to turn yellow in autumn?
Green is the natural color of the plant. Each variety can have its own shade, someone is dark green, someone is light green. With normal development, the absence of pathologies and diseases in the autumn, the juniper does not change color, and it remains green.
The only thing that can change is the hue. This is due to the fact that the foliage of a given plant produces a certain compound that protects the trunk and foliage from ultraviolet rays.
This connection can be of different colors, for example, burgundy or blue. Mixing with the main color of the foliage, the result is a burgundy green or yellow-green color.
These compounds are released by the plant not only in autumn, but also during changes in the environment. For example, when it gets cold, when the weather is too hot and dry, during rainy periods.
If the juniper turns yellow in the autumn, this can also be explained by the fact that the plant renews its needles. But in such cases, the needles should crumble and be replaced by new and young needles. Typically, this process occurs once every 5 years.
Why juniper turns yellow: reasons
There are only a few main reasons why the juniper began to turn yellow:
- The plant grows in the wrong place for it.
- Improper and insufficient care of the juniper is carried out.
- The plant is sick.
- The plant was attacked by pests.
To determine the reliable reason why the plant turned yellow, it is necessary to conduct a thorough examination of it, which will help determine. If the inspection did not reveal any pests and diseases, it is necessary to check the composition of the soil.
The first reason. Juniper turns yellow after planting and transplanting
The first reason is landing in the wrong place. This is a common reason why junipers turn yellow and dry. In such a situation, after a while, the yellowing of the juniper begins after planting or transplanting. In the place where the plant grows, there may be an unsuitable soil for it.
The landing site must be carefully selected and meet certain criteria. Usually the plant grows in places that are well lit by the sun's rays. In a pine or deciduous forest, on the edge or near a road.
An ideal landing site would be a semi-shaded area. That is, it is half well lit. And half darkened by some other tree. The soil should not be alkaline or acidic, but medium in acidity.
This plant reacts poorly to excess moisture. Therefore, it should not be planted near a swamp or in a place where groundwater is nearby.
Juniper is planted only in open ground. This is usually done in mid-spring. In the second half of April or early September. This weather is perfect for landing.In no case should there be heat and strong wind on this day.
If the juniper was not purchased, but taken from the forest, then it requires even more care. This is because he is used to the place where he grew up. And the gardener may, out of inexperience, put him in an uncomfortable place. In this case, the plant takes root very poorly, or does not take root at all. Very often, in such situations, the plant begins to wither, becomes lethargic and dies.
That is why experienced gardeners recommend purchasing plants in specialty stores. Since there will be less problems and worries.
The juniper turns yellow and dries. The second reason
The second reason is insufficient or improper care of the juniper. Although it belongs to unpretentious plants, care still affects the yellow crown.
Yellowing can be caused by insufficient watering... This is often found in crops that grow at home or under some kind of shelter. This is very simple to explain: when growing outdoors, the plant has enough rainy days.
The only exception can be a fairly long period of dry and hot weather. On such days, you need to water the juniper better. It is even recommended to use foliar watering when the plant is also sprayed.
But spraying should not be carried out in the presence of the sun. Since the juniper will get burns and begin to turn yellow and wither. Therefore, it is necessary to spray the plant in the evening, when the sun is gone, and during the night the moisture is completely absorbed into the plant.
The foliage of the plant has a small layer of plaque that resembles wax. That is why moisture does not quickly penetrate inside, but remains on the surface for a long time. And in the presence of sunlight, the drops that are on the foliage strongly attract them. They become the lens through which the plant is irradiated.
Soil composition refers to an important criterion that must be met. The acidity should be in approximately the same position and be neutral. The acidity of the soil can fluctuate due to improper feeding. Therefore, this must be done correctly and carefully so as not to disturb the plant.
It is worth noting that the plant should not be touched by pets. They don't have to make their own toilet out of a bush. For this, it is recommended to use a net and fence the plant.
Why juniper needles turn yellow. Third reason
The weather can also affect the yellowing of the crown. Under changeable weather conditions, the plant experiences a little stress, which shows in the form of yellow foliage. This often happens when the weather is dry and hot for a long time, and then gives way to a long period of rains.
With prolonged rains, drainage can be built, which will remove excess moisture from the root system of the juniper.
The next reason that the needles turn yellow in juniper are various diseases and pests that affect the plant and prevent it from developing.
First, let's deal with pests. They often attack the juniper, starting to feed on its juice. Due to the lack of beneficial trace elements, the plant begins to stress. It manifests itself through a yellowing crown and a sluggish appearance.
Common garden pests:
Description: This pest is very popular. Therefore, almost all gardeners know that aphids, settling on a plant, begin to suck out nutritious juices. Thus, interfering with the development and growth of the juniper. Due to the lack of these substances, the plant begins to turn yellow.
Control: When infested with aphids, it is necessary to get rid of all painful shoots and foliage. Then rinse the plant with a strong pressure of water and treat it with Fitoverm or Karbofos. From folk remedies, an infusion of garlic, onion or tobacco will help. To prevent the plant from attacking aphids, you can plant feverfew or a regular onion with garlic next to it.
Description: She appears on the shoot, parasitizing it. Then it moves to the needles. She, like aphids, begins to suck out the nutritious juice. If you do not catch it in time, the plant may die due to the rapid spread of the pest.
Fighting: With this pest, the crown of the plant should be treated with Aktara, Aktellik, Karbofos. If the plant is severely affected, these parts are cut out and burned. And the places where the branches were cut off are sprayed with a solution of water and grated soap.
- Needle mite
Description: The mite begins to suck the sap from the foliage of the plant. The plant withers and turns yellow due to lack of juice.
Struggle: It is necessary to carry out the treatment with Acarin or infusion with garlic, onions or tobacco. Laundry soap dissolved in warm water will help well.
Description: It is a small pest butterfly. Being in the state of a caterpillar, it begins to feed on the trunk and foliage of the juniper. Most often, it eats everything inside the needles.
Fighting: Fighting moths is easy enough. It is necessary to carry out two treatments with Decis with an interval of 1 month. When autumn comes, you need to dig up the soil around the juniper and add fungicides to the soil.
Description: Just like a moth, it looks like a butterfly and its caterpillars eat away needles.
Fighting: Infected shoots should be removed and burned, and the plant should be treated with Decis or Fufanon.
Having dealt with pests, you need to deal with the most common diseases.
Description: Juniper needles begin to turn yellow and dry. Yellowing starts from the top and extends throughout the plant. This disease belongs to fungal. Therefore, it occurs due to the onset of rotting of the root system, which was caused by fungi.
Treatment: The fungus begins to attack the root system of the juniper at the wrong planting site. Or due to weather conditions, for example, when there was no sun for a long time. To cure a plant, it must be cleaned of infected parts and treated with Vitarox or Baktofit. If possible, it is recommended to transplant the culture to another more suitable location.
- Dry shoots
Description: Drying of the shoots of the plant can be caused by an infection that lives on the bark. With such a disease, the yellow needles begin to fall off.
Struggle: First you need to cleanse the plant of shoots, leaves that have been infected. After - you need to take copper sulfate and prepare a 0.75% solution, which you need to process the plant.
- Varieties of mold
Description: Mold can start to appear due to the influence of some kind of fungus. The defeat begins with weak and young shoots. A distinctive feature is that the branches that have been infected turn brown or gray in color.
Struggle: To prevent this disease from infecting the juniper, it must be cleared of weeds and loosened the soil after watering. Also, the plant must be treated with a weak solution of Bordeaux liquid. This disease is not cured, so the plant is completely burned.
Description: It is one of the most popular diseases of the juniper. It belongs to the category of Fungal. Distinctive features are growths on the tree trunk. They are usually orange, yellow, or red in color.
Struggle: Infected branches are pruned and burned. And the remaining bush must be processed using Bordeaux liquid.
- Biotorellic cancer
Description: This disease appears only when the bark of the culture is cracked and settles in places where there are small chips. The disease is characterized by yellowing of the needles and redness of the bark.
Struggle: For treatment, it is necessary to treat the surface of the plant with Hom. As in all cases, the infected parts of the plant are cut off and burned.
Description: This disease affects the bark of the culture. It begins its manifestation with pads on the shoot, which are red in color. After some time, the plant becomes lethargic and dries up.
Struggle: It is necessary to treat the plant with Fundazol and shed the area around the trunk with Phytosporin. Infected areas of the crop are cut and burned.
How does the season affect the fact that the juniper turns yellow?
This plant is considered to be an evergreen plant, but despite this, the color can change. This change may be influenced by the season.
Why does juniper turn yellow in summer and what to do?
Juniper needles turn yellow in summer due to lack of water in the root system. This is usually due to dry weather. Yellowing due to lack of water can be recognized by the following signs: the needles have become pale and begin to turn yellow throughout the bush.
With spotty yellowing, that is, when only the top, center or bottom of a juniper, it is recommended to inspect the culture, as it may be pests.
Why does juniper turn yellow in autumn?
With a uniform change in the color of the foliage, the plant does not have to worry too much. Since the color may change due to a decrease in air temperature and the onset of the first frost.
Due to the fact that the plant begins to secrete a special compound, the color changes and this is natural and safe. Therefore, it does not require excitement and any measures of struggle.
In the earliest fall, juniper can turn yellow on the inside. What if the juniper turns yellow inside? The fact is that this is a natural process of withering away of old needles, which will later be replaced by young needles.
Yellowing in winter
If the foliage of the plant turns yellow in winter, then this can happen due to the same reasons as in the autumn. But one more joins them. This can be caused by damage to the plant.
Due to severe frosts and cold weather, the crown may begin to break because of this. Branches that have been broken will begin to change in color. In winter, they should never be touched. But with the onset of spring, you need to remove them. Because of these wounds, the plant can become infected with some kind of virus.
Why does juniper turn yellow after winter?
In springtime, the sun's rays gain their strength and frequency. Unaccustomed, the juniper can poorly perceive these rays and burn. As a result, the juniper turns yellow in the spring.
Due to the strong sun, the needles heat up. And on them there is still unmelted snow, which, turning into water, provokes burns. During this period, the needles become pale, as if they are fading. In order to prevent this from happening, it is necessary to protect the culture using a bandage or gauze.
Why do juniper needles turn yellow and dry?
In order to determine the cause of yellowing to gardeners and gardeners, a thorough examination of the juniper will certainly help. This must be done very carefully in order to determine the problem as accurately as possible. This is necessary because many crop-eating pests are very well camouflaged and difficult to recognize.
Note: After a thorough examination, you did not reveal any signs of disease or finding pests, then the problem is in ordinary care and it should be changed.
Juniper turns yellow from below, how to treat?
With a slight yellowing, it is necessary to treat the plant with Epin. This product is a water-based solution to which natural growth biostimulants have been added. Zircon can be added to this solution, which will have a beneficial effect on the plant, since it will disinfect it a little. This mixture eliminates slight yellowing.
To prepare the mixture correctly, you need to take 5 milliliters of each substance and stir them in 4-6 liters of water, depending on the scale of yellowing. The larger the scale, the higher the concentration of the solution. This solution is used in the processing of the crown 2-4 times with breaks of 3-7 days.
Due to the polluted atmosphere, the plant can also turn yellow. This usually happens if the juniper is located next to roads or some kind of factories. A terrible ecology will greatly affect the plant.And it will feel bad and show it in the form of yellow areas.
This situation is considered incorrigible. Since it is impossible to change the ecological situation. Transplanting to a greener location might be the only way. But it is not a fact that the plant will take root well on it.
Juniper loves moist soil, but not excessively moist soil. It is just such a soil that he does not treat well. Watering the crop depends only on the condition of the soil. If it starts to dry out a little, you need to water it immediately. Watering is not carried out in moderately moist soil.
Experts recommend mulching the soil after each watering. Since this will keep moisture in the soil for the maximum possible time. At times, you should check the soil for acidity. This test will not hurt, especially since it is done very simply. Such tests are sold in shops associated with the garden and vegetable garden.
Caring for juniper in the country, if it turns yellow
Preventive measures are great for avoiding yellowing of the plant. Prevention consists in treatment with antifungal agents. Also, regular check-ups will reduce the risk that the juniper will contract any disease.
At the initial stage of the disease, it is much easier to get rid of it than to treat a severe stage.
Juniper care is also some form of prevention. Cleaning of weeds and debris in the soil should be carried out. It is necessary to loosen the soil around the culture and mulch it. It is good to use drugs that fight against the appearance of pests of the root system in the winter. The trunk of the juniper should be cleaned of old layers of bark and branches.
When spring comes, you need to think about how to limit the flow of sunlight. As they will leave burns. To do this, you can use gauze, bandage, and burlap is perfect. You can also put up a small fence. The made screen will restrict the flow of the sun.
Note: When protecting junipers in spring from sunlight, in no case should they be covered with a film, as it does not allow water to evaporate.
If the culture turns yellow, it is necessary to find out the reason by immediately examining it. Early treatment will help the plant return to its former appearance faster. Juniper is a wonderful plant that also needs care and should not be forgotten. Indeed, due to improper, careless care, he can suffer and therefore turns yellow.
