In spring and summer, the pear tree needs to be periodically carefully examined in order to help the plant overcome the disease in a timely manner.
Inspection is also necessary to determine when the tree needs to be fed.
There are three main macroelements that a pear needs: nitrogen, potassium, and phosphorus. You can determine which specific component is missing by the appearance of the plant.
The green mass develops slowly, the tree stands "naked" for a long time. The trunk and branches are pale in color, young leaves almost never appear.
The green mass may be all right. Young foliage appears, but the tree does not bloom. Or small buds appear, which soon fall off.
When there is a shortage of macronutrients, the leaves curl and fall off. If this is not the work of aphids, then most likely the problem is a deficiency of potassium.
Experienced gardeners inspect the pear throughout the season to apply fertilizer in a timely manner. Often, summer residents do not wait until the tree "asks" for it, but apply a complex fertilizer themselves, which contains nitrogen, phosphorus, and potassium.
