Gardeners often face various problems that require immediate solutions. And if a lot of brown leaves have appeared on the apple tree, there may be several reasons for this. The article will discuss not only how to determine what happened to the tree, but also how to prevent this from happening in the future.
Main reasons
The apple tree can be called one of the most common fruit trees. And if you love gardening, you probably have several varieties of delicious apples on your site. Nobody is immune from problems. If the leaves turn brown on the tree, and often this process affects the edges first, you need to find the cause of the problem. Despite the fact that the apple tree is considered a very unpretentious tree, it can also be attacked by pests and various diseases, for example, fruit rot or scab . Some of the causes of foliage discoloration are aphids and powdery mildew. And if you do not start to deal with the problem in time, then the tree will soon be destroyed, and the pathogen will spread to the entire garden.
With a lack of nutrients, any apple tree will begin to fade . The leaves will soon dry up and turn brown if you do not tackle the selection of suitable fertilizers. Often this indicates a lack of phosphorus and potassium, so they should be used primarily at the beginning of the flowering period. If the plant receives an excessive amount of nitrogen, then soon it will suffer from a lack of copper, which is designed to ensure yields. If the edges of the foliage are curled, this means that the tree is affected by a fire blight. Brown spots appear from scab, which captures not only leaves, but also branches, and then fruits. Even the smallest insects, for example, apple sucker, can cause harm and lead to the death of the entire garden.
The main indicator of a fruit tree disease is the leaves, from which you can determine the state of the plant . If brown spots began to appear in the center, this means that there are not enough nutrients in the soil. It can also be affected by unfavorable weather, for example, the cold season.
The land must be carefully cultivated, fertilized, which will have a positive effect on the garden and future harvest.
Treatment
When the leaves turn brown, action is urgently needed. If you find that the cause lies in pests, they need to be destroyed, for which insecticides are intended . And you will also need to check the soil - if there are not enough useful elements in it, you will need to use fertilizers. Fungicides, which are presented in a wide variety, perfectly cope with diseases. If you do not solve the problem at the initial stage, the leaves will begin to deform, and the tree will gradually fade.
With a lack of calcium, experts recommend using fertilizers based on calcium sulfate, but this is only suitable for soil with normal acidity. If the indicator exceeds the norm, it needs to be normalized. To solve the problem of boron deficiency, it is enough to dilute 15 g of boric acid in a bucket of water and treat the entire garden with this solution.
As for the fight against fungal diseases, fungicides will be needed to eliminate them . Powdery mildew will be destroyed by such drugs as Fitosporin, Topaz or Topsin, which have already proved their effectiveness in practice. When it comes to severe infection, choose products with penconazole.
In cold weather, copper preparations can be used to prevent burns on the plant . There are several varieties of remedies that are used by many gardeners when leaves dry on trees. Experts recommend choosing biologicals that are excellent alternatives to chemicals, especially when spraying young trees. This procedure will help strengthen the immunity of the entire garden, and he will be able to fight diseases.
Prevention measures
If there is no problem with brown leaves in your garden, this does not mean that you do not need to prevent the development of various diseases. Prevention plays an important role in horticulture, so it is necessary to heed the recommendations and do what the experienced professionals say . Special care is required for fruit trees, therefore it is important to conduct a thorough inspection of the site, thin out the crowns so that there are not too many branches, as they prevent the ingress of sunlight. During pruning, it is important to properly process the cut points, and then apply organic matter as fertilizer. If the season is dry, you will not be able to do without high-quality watering.
If you initially process garden trees using biologically active preparations, you will save yourself many problems . Akarin copes well with insects, and fungicidal agents should be used against microorganisms. For processing, you will need a special sprayer, and the active substance must be diluted in the amount of water specified by the manufacturer. To stimulate growth, you can mix drugs that have different properties, but it is better to study the issue in advance.
In order for the trees to be strong and stable, it is necessary to feed the soil, it is better to choose organic fertilizers . In order for the leaves to grow green next year, and not brown, the procedure must be carried out at the end of autumn, so the garden will stock up on strength before winter. Top dressing with watering is introduced not only under the trunk, but also around the whole circle, you can navigate by the size of the crown.
In order to avoid the development of putrefactive fungi, which can also cause stains on the plant, the fallen leaves should be removed and burned, and the ashes should be used as fertilizer . Another stage of prophylaxis is the processing of cut sites with pitch.
It is forbidden to use any chemicals during the ripening of the fruit if you want to get a healthy natural product.
