Why do the leaves on the apple tree turn brown and what to do?
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, it 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.

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, do an excellent job with diseases.

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.
