It so happens that a pear blossoms and forms many ovaries, but later they fall off. The phenomenon upsets gardeners, since the falling of the ovaries on the tree leads to the loss of the crop.

There may be several reasons, so regular inspection of the plantings is important in order to notice and fix the problem at an early stage. If this is not done, then you can lose not part, but completely of the entire crop, and in some cases the plantings themselves.
To take effective action, it is necessary to correctly identify the cause of the problem. Let's figure out why the pear sheds fruit ovaries and what to do in this case.
What can cause the shedding of the ovaries
According to experts, the cause is rarely one. Most often it is a combination of factors. The most common ones are presented below.
Opens the watering irregularities list. Lack of water, like its excess, negatively affects the condition of the tree. Focus on the optimal pear watering regime. It is equal to five to six times per season. In this case, it is advisable to adhere to an equal time interval between waterings, and the soil should be moistened to a depth of about 40-60 cm.
Gardeners are not always able to predict precipitation, it so happens that after heavy watering, a downpour begins. This is fraught with waterlogging, therefore, as they say, "it is better to under- than over-". With a lack of moisture, it is easier if you see that the ground has dried up quickly after abundant watering, then you should water the trees again the next day.
Another factor that can be difficult to predict is also related to the weather. This is a strong wind, especially when combined with rain. The stronger the wind and rain, the more difficult it is for the ovaries to stay on the branch. We all saw that after a strong wind, the trees look badly shabby, it simply blows off the leaves and ovaries.
The list of negative factors leading to the loss of crops and fertilizers continues. Lack, insufficient amount or wrong choice of fertilizer can also lead to the fall of the ovaries. Fruit trees, including pears, need a lot of nutrients. If you do not apply fertilizer in autumn or spring, you can not count on a good harvest. A tree that does not have the resources to develop all the ovaries will get rid of some of them.
Insufficient connection of the stalk and the branch is not common, but this reason cannot be ignored, because it also leads to the fall of the ovaries. This is a genetic defect and, unfortunately, there is no way to eliminate it. We will have to replace the existing diseased tree with another planting material, which, by the way, can also have the same pathology.
Freezing or freezing of the soil are also factors that increase the likelihood that pear ovaries or flowers will be damaged. A sharp drop in day and night temperatures (10-12 degrees) often leaves gardeners without pear harvest.
The composition of the soil has a significant impact on the condition of the tree. A pear growing on depleted soil will not yield as much fruit as growing on a fertile one. The increased level of soil acidity also adversely affects.
Mechanical damage to the tree provokes the fall of the ovaries. If the skeletal branches of the tree are damaged, then the ovaries will automatically fall off the shoots extending from them. Incorrect pruning of the pear will produce the same result.
Diseases and pests are among the most common causes of ovary problems in pears. Of the diseases, these are usually scab, rust and rosette, and the most dangerous pests in this sense are the peduncle, the flower beetle, the sawfly and the copperhead.
Prevention and elimination of problems with the ovary
Correct and timely measures taken are the key to preventing or minimizing crop loss. But, unfortunately, it will not always be possible to save the tree on which the ovaries began to fall off.
Maintain the optimum soil moisture level. Fluid retention is facilitated by mulch with a layer thickness of at least ten centimeters. The watering norm for trees from 3-5 years old is 5-8 ten-liter buckets. Planting 6-9 years old needs 10-12 ten-liter buckets of water. In addition to watering, systematic loosening of the soil is necessary, at least twice a season.
Urea solution helps to reduce the percentage of ovary shedding. For a ten-liter bucket of water, you need two tablespoons of the drug. The whole tree should be sprayed, in dry and calm weather. And here is a popular recipe. Cover a bucket with weeds, 10 grams of superphosphate and a glass of ash and leave for a week or two. Each tree (4-5 buckets) is watered with the resulting infusion, diluted with water before use (a liter of infusion per 10 liters of water).
The increased level of soil acidity is corrected by the introduction of dolomite flour - 300-500 grams per square meter. The substance is not added near the trunk of the pear, you should retreat by about a meter. You can also bring several machines of high-quality soil to the site.
It is impossible to give unequivocal advice regarding pests and diseases. Gardeners recommend two relatively universal remedies: Skor (2.5 mg per 10 L) and Horus (10 mg per 10 L). A mustard solution (10 g per liter of water) in an amount of 2.5 liters at one time several times a month is also effective.
