Why the leaves of the apple tree turn yellow: reasons, what to do and how to treat

During growth, fruit trees are often exposed to negative external influences and die. In unstable weather, frosts and the development of infections, it is possible to damage the trunk, leaves and crown of green spaces. When wondering why the leaves of an apple tree turn yellow, it is necessary to understand the causes of the problem and take measures to restore it.

Common causes of yellowing leaves and their solutions

In practice, gardeners are faced with a number of standard reasons due to which the leaves of apple trees change color, after which they dry out and fall off. Having found out the exact cause, based on certain symptoms, it will be possible to find a solution and save the plant.

Why do leaves turn yellow?

In most situations, yellowing of vegetation provokes improper care or the presence of an external irritant. Methods of healing plants depend on the specific cause of the disease.

Diseases

A common apple disease is fruit rot. A pronounced sign of the disease is yellowing of the leaves in early June with the onset of the first heat.

For the prevention of diseases, it is necessary to treat seedlings with fungicidal products.

Pests

Leaves and buds of trees are most often affected by the hawthorn mite, which can suck out the nutrients necessary for proper growth and intensive fruiting. Weakened leaves fall, and the yield is significantly reduced. To repel pests, spraying with insecticidal preparations is required.

Feeding

Lack of nutrients in the soil slows down the development of new shoots and negatively affects the growth of foliage. It is recommended to fertilize the soil on which apple trees are grown with the addition of iron and phosphorus.

Fertilizers

It is necessary to fertilize the land with fruit plantations several times during the season. Suitable fertilizers:

• ammonium nitrate;
• humus;
• chicken manure infusion.

Groundwater

The accumulation of groundwater in excess leads to rotting of the roots. As a result, the disease passes to the upper part of the trees, and the bulk of the leaves turn yellow. To prevent a problem, you should choose the right landing site.

Problems arising on a young apple tree

On young seedlings, the problem of yellowing foliage occurs more often than on rooted trees. Newly planted apple trees should be carefully cared for so that the plants adapt to the environment.

Yellowing of seedlings

Change in the color of the leaves on the seedlings is due to the wrong place or deepening. In the wrong place, the roots will not have enough oxygen due to the increased soil moisture. Exceeding the planting depth by 10-15 cm also interferes with root development.

Seasonal yellowing of leaves

Deal with damage to foliage on apple trees should be based on the current season. Inexperienced gardeners often find leaf growth declined in early spring and hot weather.

Spring

The appearance of yellow leaves in spring is due to the defeat of brown spot or scab. Fallen leaves must be raked and destroyed, and the tree must be treated with a Bordeaux mixture.

Summer

With the onset of heat, the rapid yellowing of vegetation provokes an excess or severe shortage of trace elements. Also, the disease can be associated with physiological disorders of the life of trees.

Other causes of yellowing

There are special cases when apple trees wither and fruits fall from them. Each case has individual symptoms.

On specific branches

Partial discoloration of vegetation indicates aphids infestation of individual branches or freezing of roots. Nutritional deficiencies may also be the cause.

Yellowing and drying

The reason why the leaves dry is due to the formation of a fungus or damage by pests that suck out nutrients. Periodic maintenance is recommended to prevent the problem.

Twisting and falling off

Sucking aphids juice from the green part of the crown leads to twisting and death of shoots. To destroy pests, treatment with specialized preparations or folk remedies is required.

Pale Leaves

The acquisition of a pale color occurs as a result of the disease of the plant with chlorosis. If chlorosis appears at the initial stage, copper sulfate is sprayed to eliminate the disease.

Solving problems on different varieties and rootstocks

It is necessary to decide what to do if problems are found in the development of an apple tree, taking into account the variety grown and the type of rootstock.

The way to deal with the problem and the choice of how to treat the plant depends on the variety of trees.

Yellowing of the columnar apple tree

Columnar varieties of apple trees are more likely to be attacked by rodents.To stimulate the growth of adventitious roots, hilling is required. This method is effective on dwarf plants, since the short roots of young seedlings do not need much nutrition.

Yellowing of the apple tree Krasa Sverdlovsk

When growing the Krasa Sverdlovsk variety, there is a high probability of development of powdery mildew. The disease is characterized not only by a change in the color of the foliage, but also by the appearance of a pronounced white coating. As the infection progresses, the green part of the culture deforms and dries up. To eliminate the effects of powdery mildew damage, colloidal sulfur treatment is carried out.

Useful tips for caring for an apple tree

To reduce the risk of wilting trees, you need to regularly care for them. Apple trees require periodic watering, visual inspection to detect disease symptoms, fertilization and preventive treatments.Proper and timely care contributes to the intensive development and increase in the yield.
