There is nothing surprising in the fact that the tree sheds its ripe harvest, but why do the fruits fall off if the time has not yet come.
This question is asked by many summer residents who grow pears. But the problem is not always related to a lack of moisture.
Often the reason is a lack of nutrients. In this case, not only pears but also apple trees shed their fruit. To save the harvest and avoid the problem in the future, you need to feed the plants.
How to feed a pear and apple tree so that they don’t drop fruit
1. At the end of April or beginning of May, add 3 glasses of urea per 1 tree. Sprinkle the product in the trunk circle.
2. The next feeding is done when the trees are in bloom. For 200 liters of water (1 barrel), take 5 glasses of superphosphate and 3 glasses of potassium sulfate. Stir and leave for a week. The resulting infusion is watered at the roots of the trees (4-5 buckets per adult plant and 1 per young plant).
3. At the initial stage of fruit ripening, the following top dressing is applied. For 200 l of water, 20 g of dry sodium humate and 5 glasses of nitrophoska are used. Consumption: 3 buckets per tree.
4. After harvesting, care for the pear and apple trees is not interrupted. To prevent the plants from shedding their fruit next year, you need to add 1 cup of potassium sulfate and 1.5 cups of superphosphate. Fertilizers are scattered in the trunk circle, and then watered.
5. To keep the trees in good shape, every 3-4 years add 5 buckets of rotted manure under the plants. Fresh manure cannot be used.
Auxin deficiency
There are certain varieties of apple trees (Antonovka, Idared, Jonared) that often drop fruit for no apparent reason. In this case, we are talking about a lack of growth stimulants called auxins.
A clear sign of deficiency is deformed, "bruised" fruits. To replenish the supply of auxins, the tree crown should be sprayed with "Heteroauxin" (50 mg per 10 l of water).
