Summer residents note that over time, apple and pear trees produce weaker harvests, which is why they start thinking about planting new trees.
However, to understand exactly why yields are falling, you need to take into account several nuances.
Thus, if an apple or pear tree is grafted onto seed rootstocks of pome crops, their lifespan can reach 70 years, and in some cases exceed 100 years. This is especially true for pears.
If we are talking about clonal rootstocks, then the lifespan of the trees is shorter. However, not by much. On dwarf rootstocks, apple trees live at least 30-35 years.
Thus, most often the yield falls due to improper care. For example, when the crown is very dense.
What to do
Formative pruning is carried out in February-March. This way the tree will save resources and direct them to the development of fruiting points.
The list of gardening chores also includes fertilizing, treating for diseases and pests. Trees often suffer from aphids, scab and powdery mildew. As a result, the fruits are small and sour.
When the tree is at the stage of flowering and formation of ovaries, complex fertilizers with microelements (boron, zinc, molybdenum, sulfur) are added.
