Experienced gardeners always put a stone in the planting hole when planting stone fruit trees.
What this gives is explained by the expert of the online publication Belnovosti, agronomist, landscape designer Anastasia Kovrizhnykh .
This is an old but very effective method of improving the fruiting of stone fruit trees (cherry, plum, peach, apricot, walnut).
A large stone (or several small ones) should be placed directly into the planting hole.
In spring, the stone will maintain a low temperature in the soil, thereby preventing the tree from blooming early and protecting it from recurrent frosts.
Yes, such a tree will bloom later than usual, but the flowers will not fall off due to frost, and there will be a good harvest every year.
