When a gardener notices that a cherry ovary is falling off his plot, he immediately seeks to correct the situation. To help trees competently, you should know the main reasons for what is happening and the most effective ways to avoid it.
Why does cherry shed fruit?
Dropping ovaries leads to the loss of a significant part of the crop. Sometimes the cherry falls off after flowering. This can happen for various reasons, so it will not be possible to do without analyzing the situation. There are several opinions on this issue. Some believe that this is the natural process of getting rid of a tree overloading it. Others urge you to thin out flowers and ovaries yourself to avoid such a nuisance. Still others are convinced that the problem is caused by the characteristics of the tree or by irregularities in maintenance. If we adhere to the latter point of view, then there are several reasons that lead to shedding of ovaries on cherries. This will allow the grower to preserve the crop and prevent this from happening again.
The most common reasons why cherry fruits fall
Depending on the cause, dropping the ovaries results in varying degrees of damage. Consequently, the actions to eliminate it will also be different.
The main reasons, their action and remedies are presented below.
An overestimated indicator of soil acidity
If such a parameter is found, the soil should be deoxidized. Lime deficiency leads to excessive overgrowth of the leaf cover. The fruits do not have enough nutrition, they do not set. If ovaries are formed, the cherries will be small. More often than not, they do not ripen, and the green cherry still crumbles. The introduction of dolomite flour (400 g per 1 sq. M.), Infusion of wood ash or chalk (1 tablespoon of the substance per 10 l of water) within a radius of 1 m from the cherry trunk works well.
Unbalanced diet
A very important reason. Most often, it is she who causes the ovaries to fall off on the cherry tree. Nutrient deficiencies result in little or no flowering. The tree may stop growing altogether and shed the ovaries. To fix this, you will need to feed with a complex mineral fertilizer (50 g per 1 sq. M). Alternate the composition with the infusion of bird droppings or mullein, the consumption of the working solution is at least 30 liters per tree. Another option is a special preparation "Ovyaz" for cherries, saltpeter, urea in combination with superphosphate and potassium sulfate. The number of dressings should be at least 2-3 times during the season. The most important period is spring before bud awakening and after flowering. It should be remembered that you cannot apply lime and manure at the same time. Also, when planting seedlings, nitrogen fertilizers are not added.
Thickened crown of a tree
This fact leads to a lack of lighting for the ovaries, and they fall off. The situation can be corrected by competent spring pruning of the tree before bud break. Especially those branches that grow inward or thicken the middle of the crown. After harvesting the fruits, sanitary pruning of young shoots should be carried out again.
Moisture deficiency
When the cherry blossoms and sets fruit, it needs water very much. As soon as the soil moisture decreases, it sheds the ovary. It is necessary to monitor the weather conditions in spring, making up for the shortage with watering in time. It is better to do this in the evening along the ring canals at the border of the crown. It is good to combine watering with top dressing.
Variety characteristics
This point refers to sterility. Even popular varieties can be self-fertile. Therefore, the absence of pollinating neighbors will lead to the absence of ovaries. It is best to buy self-fertile seedlings that guarantee an annual harvest. To navigate, you need to remember that there are three types of crop varieties - self-fertile with 5% of the ovaries, partially self-fertile with 20% of the formation of ovaries and self-fertile with 40% of the ovaries.
Overload with last year's harvest
After a fertile year, cherries need to recover. Therefore, it sheds a significant part of the ovaries. Such varieties require special care. It must be regular and of high quality. Autumn dressings play a special role. Along the border of the suction roots per 1 sq. m of soil, lay humus (15 kg), superphosphate (300 g), a mixture of potassium with magnesium (100 g). Deepen the nutrient composition by 20 cm.
Groundwater height
Cherry belongs to crops that are very sensitive to the parameter. It grows well if the depth is at least 2 m. The close location of water to the surface of the soil oppresses the plant. It is optimal to plant a cherry orchard on a natural or formed hill.
Weather conditions at the time of flowering
Pollen is capable of fertilization for 3-5 days. If at this time there is a heat, then it crumbles. If it rains, insects do not fly and do not pollinate the cherry. To attract bees, honey water is used (100 g of honey per 1 liter of water).
Growing non-zoned varieties
The reason is commonplace, but also common. The inconsistency of the conditions and characteristics of the tree leads to the absence of an ovary.
Diseases
The falling off of the ovary is considered one of the symptoms of clasterosporia, as well as cocomycosis. With the latter ailment, the cherry sheds its green fruits. Trees need proper care and treatment.
Pests
The most common cause is cherry fly or cherry weevil. Planting of early varieties, preventive measures, adherence to agricultural techniques helps.
What to do to prevent the cherry from dropping the ovary
There are several activities that save the cherry harvest:
- Reducing the acidity of the soil by introducing appropriate preparations.
- Timely and correct pruning of the tree in early spring and after fruiting.
- Regular and competent feeding of cherries.
- Watering taking into account weather conditions and plant condition.
- Regulation of the position of groundwater by means of measures for their diversion.
- Attracting bees and other insects to the garden to pollinate varieties.
- Selection of inter-pollinated varieties.
- Fulfillment of the schedule for preventive treatments of cherries against diseases and pests.
- Regular inspection of trees and removal of damaged parts.
- Weeding the site, loosening the soil, enrichment with organic matter.
- Cleaning of fallen leaves and fruits.
A very important step in the care is the correct choice of spray products.
How to process cherries so that the ovary does not crumble
If berries fall on the cherry, spraying the tree will help. Gardeners recognize Bordeaux liquid as the optimal composition.This operation is often referred to as “blue spraying”. The substance protects cherries from infection with fungal infections. Spraying should be carried out in early spring, when the buds are just bursting.
This period is called "along the green cone". It will need 3% Bordeaux liquid. The second spraying should be done at the time of active growth of the cherry, when new branches and leaves appear. For this purpose, a 1% solution is prepared. The effect is enhanced if you treat not only the crown, but also the trunk and the peri-stem circle.
When diseases appear, fungicide treatments are needed, pests are destroyed with insecticides.
Prevention measures
Preventive actions consist in careful adherence to the agrotechnics of cherry trees. Every year, plants are treated with solutions from the appearance of pests and diseases in the garden.
Do not forget to fertilize the soil, especially in the autumn after fruiting.
Young trees must be covered for the winter so that the buds do not freeze.
Timely removal of fallen fruits does not allow pests to multiply and diseases spread. You also need to pick ripe fruits in a timely manner so as not to overload the cherries.
Experienced gardening tips
If a cherry tree blooms very profusely, then this does not guarantee a rich harvest. Before flowering, it is necessary to add a urea solution (25 g per 10 l of water) to the near-stem circle. And after the flowers open - an organic infusion of mullein or bird droppings. After flowering, you need a mineral complex (50 g per 1 sq. M). This alternation of nutrients is good for strengthening the vitality of the cherry.
Another subtlety: you cannot take root shoots of a tree for planting. If it is grafted, then you can get a game, not a variety.
Gardeners need to know that proper care and careful adherence to agrotechnical recommendations will save cherries from dropping ovaries. Therefore, you should once again recall the possible reasons presented in the video:
Conclusion
The reasons why the cherry ovary falls off can not only be removed, but also prevented. Caring for the tree will definitely give the desired result.
The cherry tree is about 10 years old and we just can't wait for the fruits ... It blooms profusely, the fruits are tied in large quantities. but ... Some moment comes and she drops the green fruit !!! all! However, foliage is not. Kamedetechi - no. for all the time - not once. Outwardly, it is impossible to determine any disease. things are good. The foliage is dense. No visible signs of any disease. The trunk is clean. What is we do not understand. Help me please.
