Falling off of fruits of plum - quite widespread phenomenon, the factors influencing it, weight. It is necessary to fight against dropping by the culture of unripe fruits as soon as possible, in certain cases trees for a short time can ""throw off"" practically all harvest.
If plum has begun to dump fruits, then first of all it is worth reviewing the care for culture, is the main reasons of the events:
- lack of moisture;
- lack of nutrients;
- attack of wreckers;
Exhaustion of the soil and lack of moisture are the main reasons of falling off of fruits. The fact is that plum has the special structure of roots - they do not leave deep into, most often their depth does not exceed 60 centimeters. That plants received enough power supply and moisture, it is better to carry out watering and introduction of fertilizer by small portions, but is more often. And after the procedures it is necessary to loosen the soil that moisture did not evaporate too quickly. About the shortage of nutrients it is possible to judge by condition of tree: if fall down medium-sized fruits and massively leaves turn yellow - the plant lacks nitrogen if fall down quite created berries, single leaves - potassium turn yellow. And in that and other case culture it is possible to feed up mullein or chicken dung, having parted them with water 1:4 and 1:8 respectively.
The settlement on tree of wreckers, namely plum fruit stem and sawfly can become the reason of falling off of fruits of plum also. Both the insect is quite dangerous to plant, for short term they can deprive of impressive part of harvest. To fight against plum fruit stem quite difficult, during the season it gives three generations of posterity. With sawfly the situation is slightly more simply, several processings usually are enough that insects have left the oblyublenny place.
As for processing, at tree infection with plum fruit stem it is necessary to carry out processing of culture by Sumitiona solution (20 ml on water bucket), however It should be noted that medicine quite toxic, and it is necessary to apply it only at absolute confidence of defeat of plum by this wrecker. It is much simpler to fight against sawfly. It is enough to lay around tree cover, film or other and to shake culture. Adult insects will fall to the laid-out cover then they can be destroyed. The tree at detection of bugs is desirable to spray each 10-12 days with 1 percent Bordeaux liquid.
