8 reasons why pears have red leaves and what to do

Red leaves of a pear in the summer indicate violations. This phenomenon can be caused by various reasons, for example, climatic changes, improper care or illness. There are many ways to deal with red leaves - these are folk recipes and chemical preparations. The choice of treatment depends on the cause.

Causes

For a successful fight with red leaves, it is important for the gardener to find out the source of the problem. The reasons may be different:

• a sharp temperature drop, atypical for the region of heat (the leaves not only turn red, but also curl);
• phosphorus deficiency (first manifested in small specks that quickly increase in size);
• excessive irrigation or close proximity of groundwater (the roots do not have enough air);
• too deep roots (improper planting);
• illnesses;
• harmful insects;
• excess lime in the soil or in fertilizers;
• incompatibility of stock and scion.

Symptoms

Depending on the cause, the symptoms appear in different ways. Long before the onset of autumn, red leaves may appear on the pear. The surface either changes color completely, or spots appear on it. In addition, the leaf loses its shape and begins to curl or dry. Having noticed one of these symptoms, an experienced gardener immediately begins to understand the causes and take measures to save the tree.

Treatment

Ways to deal with red leaves vary. If the plant was originally improperly grafted (incompatible stock and graft), the tree is doomed to death. In other situations, timely treatment, or changes in care, helps save the tree.

Replenishing phosphorus deficiency

If the leaves change color unevenly, from the bottom (from the petiole), most likely the reason is a lack of phosphorus. Next spring, you need to make mineral fertilizers, as well as spray trees every 15 days with a solution of ammophos.

Excess moisture removal

If water regularly accumulates at the landing site (melt, rain, ground), it is important to organize drainage grooves. It is also necessary to monitor the amount of watering, not exceeding the norm. If the tree is young, it is better to transplant it to a higher section.

Folk methods against insects

Often the cause of redness is aphids. To combat it, use the following algorithm:

5. Dilute 200 ml of infusion in 10 l of water.
6. Spray the plants several times with a break of 4-5 days.

To cope with the attack of ticks, the drug "Masai" or "Omight" helps. Treatment against these parasites is carried out twice per season.

Disease control

One of the serious diseases of the pear is black cancer. Trees often also suffer from fungal diseases. A common symptom of disease is reddened leaves. Plant treatment algorithm:

1. Remove the damaged bark.
2. Tear off red leaves.
3. Trim off diseased branches.
4. Burn all affected parts.
5. Carry out treatment according to the instructions.

Resistant varieties

The more resistant the pear is to diseases and pests, the less often you can observe such an unpleasant symptom as red leaves in the summer. "Strong" varieties:

• August dew;
• Spiritual;
• Wizard;
• Northerner;
• In memory of Yakovlev;
• Tikhonovka;
• Chizhevsky.

Prevention

You need to plant a pear in a high place, without deepening the roots too much in the soil. To prevent phosphorus deficiency, as well as to protect plantings from diseases, you can treat the trees with chemicals:

1. "Azofos" - the prevention of diseases and insects. Dilute immediately before use - 100 ml per 1 bucket of water.
2. "Speed" - use before flowering, so as not to harm the ovaries. 5 ml diluted in 10 l of water. One tree requires 1 liter of solution.
3. "Delan" - from pests, it is better to use after flowering. Consumption - 1 kg / ha.

Advice

Novice gardeners are better off choosing sustainable varieties.

When buying a pear seedling, you need to make sure the manufacturer is professional. If the stock and scion are incompatible, the tree will not only bear fruit badly, but may also die (the first signal is the redness of the leaves).

It is better to carry out preventive treatment of diseases and pests than to treat plants later and deal with the consequences.

Conclusion

Pear damage by pests or diseases is often manifested by the appearance of red spots on the leaves. If even a small speck is found, treatment should be started immediately. Another cause of leaf redness may be improper planting or care. In this case, emergency measures must also be taken.
