Why does cherry blossom but not fruit and what to do about it?
It is believed that the better the culture blooms, the more fruits it will bring.However, this is not quite true; abundant spring flowers on cherries do not always guarantee a good harvest of berries. The question arises: what is the cause of this trouble? Let's try to figure it out.
What is the reason?
Unfortunately, the reasons why cherry blossoms and does not bear fruit can be many. One of them - the wrong planting seedlings.
To avoid this error, you should pay attention to some points. First of all, it is necessary to take into account that for good growth of a cherry it is necessary to choose a suitable soil. The best option would be sandy neutral soil. Fertile soil as well as shady areas, as well as marshland will not work. Seedlings should be bought in proven places, so that there is confidence in their quality. During planting it is necessary to ensure that the root neck coincides with the ground level.
The landing site itself also plays an important role. The area on which the tree grows should be warm and sunny, and strong winds should be excluded. Soil drainage and neutral acidity are indispensable conditions for a good harvest.
You should also pay attention to proper watering and feeding. For a tree to develop well, it must be watered several times during the season. If nutrients are missed, this can lead to the formation of the ovary, but in this case there is no fruit to wait.
The problem can be solved by fertilizing with complex mineral fertilizers. Does not hurt and organics. Increased acidity of the soil must be normalized. This is done by adding wood ash.
Sometimes the cherry can bear fruit for several seasons, after which it suddenly ceases to give berries, while flowering, as before, does not portend trouble. In this situation, it is possible that unfavorable weather conditions are to blame. They affect the tree in several cases.
For example, flower buds may die if there were severe frosts, since pollen loses its quality at very high summer temperatures, and insects that pollinate flowers are less active in rain and high humidity conditions.
It is impossible not to pay attention to trimming plants. It is necessary for the cherry to develop properly.
However, here it is necessary to take into account all the subtleties and nuances of the work, since mistakes can lead to unpleasant consequences. If you cut the bouquet twigs, you can lose a sufficiently large number of berries, because each branch can bear fruit for up to 3 years.
If the branches are cut too hard, the tree will be injured, which will affect its general condition. You can also not remove the shoots of the same age, as they will turn into the next season in the bouquet. However, this does not mean that you need to abandon pruning or carry out it superficially, since this is fraught with thickening of the crown, as a result of which the berries will be much smaller, and their number will significantly decrease.
If the spring was cold, with occasional frosts, it can lead to freezing of fruit buds. The situation is unpleasant, as in previous cases: there are flowers, there are no fruits.
For the ovary, the temperatures below zero are destructive, it will freeze and crumble. However, this does not mean that there are no options for saving the harvest, because the wintering of cherries can be extended if desired. For a start, you should not get rid of snow, which is located at the trunk of a tree. If the cherry has reached a large size, a nearby fire will help, emitting a lot of smoke. A small plant is best wrapped with a cloth that helps to survive the cold.
In the autumn, you should stop watering the cherries; you should not feed the plant with nitrogen either. If this is not done, the root system may freeze in winter.
Lack of pollination
Inexperienced gardeners in the hope of a bountiful harvest can plant only one tree on their plot.
If the variety does not provide for self-pollination, the cherry will not please you with tasty berries. In order for the fruits to appear, besides the self-pollinating one needs to plant another variety, only this guarantees good fruiting. Also responsible for pollination bees. If there are not enough of them on the plot, the result will not be good. The number of bees depends on weather conditions and the impact of toxic chemicals on the plant.
An exit can be sprinkling the tree in color with sugar syrup, for its preparation you will need a glass of water and a tablespoon of sugar. If desired, sugar can be replaced with honey.
The distance between the trees also plays an important role. If they are located far from each other, effective pollination will not work. The distance between the seedlings should be no more than 40 meters, and flowering should occur at one time. Stimulant drugs are the "Ovary", "Bud" and "Pollen".
Diseases and pests
If the gardener could not wait for the harvest, fungi and various infections can be to blame. It is also possible that this happened due to the impact of harmful insects. Among the diseases of the cherry, coccomycosis and moniliosis are the most common problems. As soon as the first factors indicating their manifestation are noticed, measures should be taken immediately.
Kokkomikoz - a fungus, due to the impact of which the wood matures worse, shoots become more tender and can not always survive the winter. This leads to the fact that flower buds freeze slightly, and the cherry can not bloom and bear fruit. The disease manifests itself at the end of spring or at the very beginning of summer, and initially represents a small reddish spots on the leaves. Later the sheets turn yellow, curl up and fall off.
The most unpleasant thing in this disease is that it proceeds very quickly and can affect a large number of plants.
All cherry nearby is under threat. The beneficial effect is hot weather and high humidity, as a result of which the tree may soon remain completely naked. Therefore, it is very important to periodically carefully examine the cherry.
Moniliasis is a systemic disease, it affects cherry flowers, which can lead to a lack of fruit and the death of the plant.
On the leaves there are spots like burns, and the berries are covered with rot. A favorable factor for the development of the disease is coolness and high humidity at the moment when the tree has blossomed. The fungus begins its destructive effect from the shoots, gradually moving to the berries themselves. Also carriers are harmful insects, for example, weevil, aphid and moth.
Damaged areas of the cherry must be carefully processed, because it is in them that a collection of fungal spores appears. Circumcision of such an area should be done by capturing some healthy material, after which treatment with copper sulphate or Bordeaux mixture is necessary.
When the cherry recovers, you need to periodically carry out prevention. Besides the fact that pests can carry the infection, they themselves are quite capable of harming cherries.
Cherry aphid and mucous sawfly cause serious damage to the leaves of the plant. Weevils are especially dangerous for flowers; it is on the ovary that they lay eggs, from which the larvae later hatch, which leads to the fall of the fruit. Hawthorn feeds on buds and young foliage, while caterpillars of the cherry moth destroy fruit buds.
Nutrient Shortage
Care for cherries is quite difficult. For her, both nutritional and moisture deficiencies and their excess are equally bad. Any of these conditions may result in the tree shedding its ovary. As a consequence, it is impossible to prevent over-wetting of the soil, its drying, lack of minerals and excessive amounts of nitrogen.
As soon as problems begin with the ovary, it is necessary to normalize the number of fertilizing and properly organize watering. Excess nitrogen fertilizer will have a negative effect on the plant.
Also, if there are problems with the flowering and ripening of berries, it is necessary to refuse feeding with manure, as it stimulates the vegetative process, which can affect the normal maturation of the kidneys. Also, to eliminate nutrient deficiencies, use potash-phosphate fertilizers.
Corrective measures
So what to do if the cherry blossoms, but does not give the long-awaited fruit? First of all, you need to ensure the proper care of the tree and closely monitor all its changes.
If there are concerns that flower buds may freeze, you need to try to delay their flowering. This is done in the following way: the trunk circle is covered with snow, and the tree should be covered from above with a special material. In the case when the flowers have already opened, and the weather forecast predicts the onset of frosts, you need to process the cherry with the Epin-extra.
In order for the disease not to develop, it is necessary to periodically inspect the cherry to see if pests and fungus have not settled on it. If a problem is identified, it should be resolved immediately.
As for coccomycosis, gardeners recommend treating the affected tree with a solution based on wood ash and soap. To prepare it, you need to mix 1 kilogram of ash, a bit of grated laundry soap and dilute it all in 5 liters of cool water. The treatment should be done once a week; procedures should begin at the end of May.
With proper care, it is necessary to conduct 4 treatments per season. They are made after the plant has faded, the second time in June and July, and then after the tree ceases to bear fruit. To prevent the disease from returning next year, it is necessary to process the cherry again in the fall.
The treatment of the fungus should be carried out in 4 stages:
- before swelling of the kidneys;
- before flowering;
- upon completion of the fruiting tree;
- before the fall of the foliage.
Well helps to cope with an infection of iron or copper sulfate, as well as Bordeaux mixture. Also should be in time to whiten the trunk. Pest control is carried out by loosening the soil, removing parasites from the tree and spraying it with chemicals.
Prevention
Any problem is easier to prevent than to get rid of trouble later. This concerns the absence of fruits from cherries. Therefore, special attention should be paid to preventive measures that combat the root causes.
If we talk about preventive measures, springtime cannot be overlooked. During this period, it is necessary to prune the cherry and process it using copper sulfate. On the damage remaining after pruning, be sure to apply a garden var. Also, do not forget about whitewashing the trunk and the main branches.
In addition, the tree and its trunk circles can be sprayed with urea, a pound of water will require almost a kilogram of money. This will help get rid of spores of fungi and harmful insects, in addition, the composition includes nitrogen, which is necessary for the development of greenery. However, it should be borne in mind that after swelling of the kidneys to carry out such processing late.
In this situation, store drugs such as Fitoverm and Nitrafen will come to the rescue. To make the tree more easily tolerate adverse climatic influences, and to increase its immunity, it is necessary to use the preparations "Fitoverm" and "Akarin".
In the autumn, it is very important to carry out sanitary pruning using copper sulfate and garden pitch. Deleted elements, like all plant residues, must be burned. Also, copper sulphate must be treated as a cherry, and the earth around it after the first frost hit. Anyway, the main preventive measure is a careful and regular inspection of the tree and the timely identification of possible problems.
Tips
Experienced gardeners say that a good harvest is only among those who properly and, most importantly, regularly cares for the plant.Preventive measures are imperative. What you need to pay attention with proper care?
First of all, we must not forget about loosening the soil and its mulching. Throughout the summer you need to follow the watering, it should be quite abundant. However, in late August, watering the cherries is no longer necessary.
Organic and mineral fertilizers are also good for culture, they give the tree the necessary nutrients that promote growth and fruiting.
In addition, cherries need to thin out and cut the crown. It is recommended to choose the crops that will grow next to the cherry. The tree does not tolerate the proximity of the conifer, honeysuckle and apple. Among the flowers should not be placed near tulips, daffodils, irises and pansies. A good relationship with cherry grapes, raspberries, roses and lilacs.
