There may be several reasons for rotting.
For example, as gardeners note, this happens if the balance of nutrients is disturbed or there is excessive watering.
Also important is the incorrect planting of the tree, when the groundwater is too close to the roots.
The problem can be avoided if you follow the rules of agricultural technology and remember about mulching, sanitary pruning and whitewashing the trunk of the fruit tree so that fungi do not get to the trunk.
It is also necessary to remember about preventive treatments. You can use a weak solution of Bordeaux mixture for this before the buds open.
However, that's not all.
There is one more rule that should be followed in order to get a high-quality plum harvest.
The thing is that every autumn the garden needs to be cleared of leaves, dry grass and fallen branches. After all, pests that can harm the fruits can hide in such garbage.
