The composition of the Non-Black Earth Drain is only 7%. Why is that? Yes because
that this breed bears fruit irregularly and often does not even

Most often this occurs in early spring or late winter.

Why does the plum bloom but not bear fruit?
Pollination
One of the reasons is the lack of pollination. Plum – cross
pollinated culture. To set fruit need pollinator – tree
another variety blooming simultaneously with the first. At different times
flowering pollination may not occur.
To prevent fertilization of flowers can weather conditions: cold,
rain or strong wind. Bees pollinate plums, and in bad weather they
do not fly.
For stable fruiting it is good to have at least
one tree of a self-fruited variety. Self-bearing plants can
tie fruit from pollination with its own pollen.
They are good pollinators for other plums.

Scattering fruits
Physiological shedding of fruits is observed after abundant
flowering and setting a large number of fruits. Tree just doesn’t
able to “feed” such a crop and part of it drops.
Another thing – pests and diseases. It so happens that faded
plum, and the fruit fastened. But then the ovary falls, carpeted
the ground under the tree. And for some reason, again, the plum does not bear fruit.

Black plum sawfly.
Females lay eggs in the flowers of plum crops: thorns, cherry plums,
plums. The larvae gnaw pulp and bone. Ovary damaged
sawfly, showered. Each larva damages about five
fruits. Then goes into the ground for pupation. There winters on
depth of ten centimeters.

To combat the pest, trees are treated before flowering and
after it with inta-vir or spark preparations (1 tablet per 10 l
water). Damaged fruits destroy.
Plum cobweed.

continues to do this for another two weeks, attaching
eggs to the green ovary. Tolstonazhka is multifaceted and harms many
stone fruit cultures. The larva, having come into the world, gnaws
bone. By July, the fruits begin to fall. Larvae winter in the fallen
fruit inside the bone. Since spring, the pest life cycle
repeats.

Damaged pest fruit collect and dispose of: burn
or drowned in water. It is not recommended to bury them.

Plum moth
Также может вызвать осыпание fruits. Butterflies lay eggs on
fruit. In about a week, the caterpillars hatch. Several hours
they crawl on the leaves and fruits. AT этот период они уязвимы для
treatments with pesticides. Then the caterpillar bites into the fruit and
moves to the stalk, eating the flesh. Fruit опадают. AT одном
