Why cherries don’t bear fruit on Supersadovnik.ru

Reason 1 Acidic soils on the site

Cherries do not grow well in highly acidic soils. It should be noted that in the middle zone almost all soils have low pH values, however, in wetlands and former clearings of coniferous forests, soil acidity is much more pronounced. In such places, without additional agrotechnical measures, cherries do not take root well and, accordingly, may not bear fruit.

In the described situation, it is necessary to regularly add alkaline components to the soil. The most effective are limestone and dolomite flour. It must be added not only to the planting hole when planting a seedling, but also regularly incorporated into the soil around the perimeter of the tree trunk circle. To do this, a groove is made approximately 1/2 the depth of a shovel, dolomite flour is placed in it and covered with earth.

Distance Rule

One of the reasons for the decrease in cherry fruiting is thickened planting. There must be at least one meter of air drainage between individual trees. When planting young seedlings, they are placed at a distance of 3 - 5 meters from each other.

As you can see, growing a strong and fruit-bearing tree requires minimal care and timely sanitary pruning and treatment. Mechanical damage to the tree must not be allowed. Dry branches, shoots, old, dead bark on the trunk, and nests of pests must be removed regularly. If these conditions are met, cherries can bear fruit for decades.

Reason 2 Lack of pollinator varieties for cherries

Today, a large number of cherry varieties have been bred, among which there are even large-fruited hybrids of common cherries and sweet cherries - duki. Some varieties are self-fertile, but most require cross-pollination. In this regard, at least 2 different varieties of cherries should grow on the site.

In this case, it is desirable that one of them be a universal pollinator. Such varieties are Lyubskaya, Vladimirka, Shubinka and some others. These varieties are old varieties, and in many ways are inferior in taste to the new ones. However, they can help produce bountiful harvests.

Reason 3 Fungal diseases in cherries

Almost all stone fruit crops are to one degree or another susceptible to infection with coccomycosis and moniliosis. Cherry trees are especially affected by them.

Moniliosis poses the greatest threat to the harvest. The fungal spores ripen and are carried by the wind during the cherry blossom period. Infection occurs through the flower. After the end of flowering and the appearance of the ovaries, the gardener notices that the branch with the fruits set suddenly withers, as if it had been scorched by fire. This is a manifestation of the activity of the fungus, the so-called monilial burn.

To reduce diseases to a minimum, it is necessary to carry out preventive spraying in the spring. The first treatment is carried out along the green cone, the second - after flowering. It can be treated with any drug aimed at destroying fungal infections, for example, Horus or Skor. As a rule, the garden is also treated for pests at the same time.

The treatment will prevent widespread disease of the plantings, but individual branches may still be infected. In this case, the infected branches are cut out and burned.

Close proximity of unsuitable crops

Every year, when planning plantings in the garden, we take into account the rules of crop rotation: the previous crop determines the next one, not all of them can grow next to each other, giving a good harvest. But trees grow in one place all their lives, so we need to find suitable “neighbors” for them so that everyone feels comfortable. Cherry is very capricious in choosing neighbors; there are a number of crops that will negate all your efforts and deprive you of a cherry harvest: it is better not to plant any coniferous plants, honeysuckle, pears and apple trees in close proximity to cherries (or cherries from them, depending on who appeared on the site first).

Flowers are often planted in the tree trunks of fruit trees; this is very beautiful, but for cherries it will be very unfavorable to be in the vicinity of pansies, lilies, daffodils, irises and tulips. But possible and even desirable neighbors include barberry, any grape varieties, lilac or jasmine. You can place raspberries and garden strawberries, vegetable crops (beets, lettuce, onions, cucumbers or pumpkin), as well as some flowers: gladioli, calendula, lupine and marigolds next to the cherries.

Reason 4 Incorrect use of fertilizers when feeding the garden

All gardeners strive to obtain environmentally friendly products at their dacha. In this regard, they try not to use chemical fertilizers, but use only ash and manure or compost. It must be said that this is, in a sense, self-deception (not only grass is fed to cows).

Manure and compost are the main suppliers of nitrogen to the soil. Ash is a source of microelements. At the same time, the plant requires macrocomponents such as potassium and phosphorus. And if there is enough potassium in the soil, then phosphorus is less abundant. But it is he who is responsible for the timely ripening of flower buds in fruit plants.

Gardeners who use manure to feed cherries add a significant amount of nitrogen to the soil and at the same time increase the acidity of the soil. Nitrogen stimulates vegetation. If its source remains unused until mid-summer, then vegetative processes do not stop and interfere with the ripening of flower buds and young shoots. This leads to the fact that the plant does not have time to prepare for winter. As a result, in the spring, gardeners find frost holes on the trees, and vigorous flowering does not lead to a bountiful harvest.

To avoid such a result, after the start of fruiting, cherry trees stop feeding with organic fertilizers. Mineral fertilizers are chosen in such a way that phosphorus and potassium predominate in them.

Why the cherry tree does not bear fruit and drops green fruits

Often, novice gardeners notice cherries that bear fruit poorly and the dropping of fruits that have not reached the ripening period. This phenomenon occurs when the tree is busy surviving, and it simply does not have the strength to bear fruit.

Here are the most common reasons for the lack of berries:

self-sterility and other characteristics of the variety;
improper tree pruning;
choosing the wrong location;
lack of fertilizers;
age of the tree;
unsuitable neighboring crops;
the result of the influence of pests and diseases.

Let's take a closer look at each reason and try to find ways to solve the problem.

Self-sterility of the plant

Cherry is a cross-pollinated plant. Requires another pollinator for fruiting. Its absence prevents the formation of ovaries and ripening of berries.

Too thick crown

Fruit formation is complicated by the dense crown. The thickened tree directs nutrients to the growth and development of numerous shoots. He does not have the strength to form full-fledged ovaries.

Timely pruning ensures free access of sunlight to the most shaded corners, regulates the growth and development of the tree, increases productivity and accelerates the ripening of berries.

Features of the variety

For planting, zoned varieties are selected taking into account their ripening period. It is possible to obtain large yields after planting winter-hardy, high-yielding varieties. The grafted varieties are resistant to various diseases and are distinguished by large fruits.

Proximity of groundwater

The timely development of cherries and voluminous harvests are influenced by the level of groundwater. Their permissible depth when growing cherries in a summer cottage is from 2.5 meters.

Adverse climatic conditions

The formation of ovaries and the ripening of fruits are influenced by weather conditions. In a cold year with a rainy summer, the activity of bees is significantly reduced, and the pollination process is delayed or does not occur at all.

Hot weather with dry summers contribute to the drying of pollen. The cherry remains unpollinated. As a result, non-viable ovaries are formed, and the fruits fall immature.

Heat-loving varieties in regions with cold climates often freeze slightly during late frosts.

Lack of nutrients, unbalanced feeding

With meager yields, cherries respond to a lack of nutrients. The lack of nitrogen and potassium is immediately reflected in the level of fruiting.

In spring, the tree is fed with complex fertilizers. When ovaries begin to form on the cherry, apply humus and mineral fertilizers.

Moisture deficiency

Lack of moisture during the formation of ovaries often provokes the dropping of green fruits. Abundant watering during this period makes it possible to preserve the harvest.

Incorrect pruning

Cherries do not tolerate mass pruning well - it causes severe stress in the tree and weakens it. Pruning annual shoots on which fruits could form threatens the lack of harvest next year.

Treatment with chemicals

Violation of the composition and doses during treatment against pests and diseases often causes the absence of fruits. An excess of chemical elements causes leaf burns, disrupts the movement of nutrients and causes a decrease in yield.

Too young or old tree

Young cherries begin to bear fruit at 3-4 years. Lack of berries after four years of age requires intervention. Trees older than 16-20 years require complete replacement or rejuvenation procedures.

Neighborhood with other cultures

Proper organization of the orchard contributes to the full development of cherries. Neighborhood with certain cultures causes her oppression. The following crops growing nearby have a negative impact on the growth of cherries:

apple trees;
apricot;
currant;
honeysuckle;
coniferous trees.

Cherries develop well when planted together with stone fruits: plums or cherries.

Lack of pollinators

Lack of suitable pollinators nearby is the main reason for the lack of ovaries. To prevent such a situation and abundant flowering in one area, it is necessary to plant at least three different types of cherries or choose self-pollinating varieties. These are Molodezhnaya, Lyubskaya, and Generous Cherry.

Unsuitable soil

The acidity of the soil affects fruiting. Excellent yields are obtained on soils with neutral or weak acidity. Its optimal value is 6.7-7.1.

Impact of diseases and pests

Fungal diseases often cause early shedding of fruits, and sometimes their absence. Already in the first year from the moment of infection with coccomycosis, the cherry yield decreases, and after a few years, without outside intervention, the tree dies. Moniliosis can be easily identified by dried berries with a gray coating. Scab damages ripening berries and causes a decrease in yield.

Reason 5 Excessive moisture

May cherry blossoms

Overmoistening can also cause a lack of harvest in cherries. In areas with close groundwater, cherries may not take root at all. However, once established, its yield may be highly dependent on changes in soil moisture. To minimize this factor, it is necessary to organize a network of drainage channels throughout the entire site.

Freezing of fruits

Early frosts pose a great danger to cherry buds. To protect plants in the fall, it is necessary to exclude nitrogen fertilizing, which contributes to the freezing of fruits. You also need to stop watering in the fall. If the trees bloom early in the spring, and the night temperature is near or below zero, then you need to water the tree generously and throw covering material over it.

To improve resistance to weather conditions, in the spring cherries can be sprayed with Epin-Extra or Novosil.
