The reasons why plum does not bear fruit may be several. Most often, there are six reasons. By eliminating them, you can ensure that the tree is constantly bearing fruit.
Why does not plum bloom and fruit?
So, the reasons why your plum is not flowering and not fruiting:
- physiological windfall;
- fruitlessness of a tree;
- the presence of infectious diseases in a tree;
- insects - pests;
- climate features;
- conditions in which the tree is planted.
Physiological windfallThis is a defect, as a result of which the plum ceases to bear fruit. Outwardly, this can be seen when several trees simultaneously begin to bloom, and ovaries appear simultaneously on them.
But one tree cannot provide adequate nutrition to all new fruits, and as a result, part of the ovaries fall. The reason for this - weak roots.
In this case, a struggle or prevention with a defect will have no effect. There are cases when the owners of the trees form the crown of the plum in such a way that only part of the ovaries fall off, but this happens very, very rarely.Physiological windfall, this is a defect, as a result of which the plum ceases to bear fruit
Variety barrenness, the name of the defect speaks for itself. When buying seedlings, the variety was picked up incorrectly; as a result, gardeners have been unsuccessfully waiting for plums for several years.
With the help of insects, the method of cross-pollination, plum can bear fruit. But this method does not give any guarantee, because insects are active only in good weather. In the rain the flowers can not pollinate.
Therefore it is better choose fruitful varieties that are self-pollinated. Among those can be identified:
- Italian Hungarian;
- Anna Shpet;
Some infectious diseases can prevent plum trees from bearing fruit. The most common infections are:
- Klesterosporiosis. It is a fungus that affects the tissues of the newly born leaves. The mushroom looks like a small spot of reddish hue, which gradually dies, leaving holes in the leaves. The pathogenic fungus, besides the leaves, infects the branches, the trunk and even the fruits.
- Gray Fruit Rot. This disease looks like a small gray spot on the fetus. With this disease, the pulp of the fetus is rotting; externally visible small specks of ash-gray color. The germ of this disease tolerates winter time on the diseased parts of the tree.
Disease can be avoided if prophylaxis is carried out. You can burn the leaves, pluck infected fruit, and also several times per season to spray trees with special preparations.
Plum can no longer bear fruit because of the invasion of pests. This may be the larvae of plum sawflies, caterpillars of the plumpox of the plum, caterpillars of the plum moth moth.
These insects eat the seeds of the fruit and the fruits themselves. Affected fruits fall from the tree.
It is possible to fight pests by treating trees with chemical compounds, using trapping belts, digging up the earth around the tree.
The moth can be destroyed with the help of microbial preparations. Insecticides are good for tolstonozhek.
Why not fruit plum? Plum Sawer:
Weather is another factor., because of which the plum can stop to bear fruit. Kidneys after spring thaws can freeze. With temperature fluctuations and strong winds, pollen sterilization can occur. In harsh conditions, the sink is very uncomfortable, but in the heat of the drain can dry out.
Planting conditions directly affect their ability to bear fruit. Plums are very capricious trees. The ground under the drain should not contain a large concentration of acids.
To neutralize, it is possible to pour ash or slaked lime into the ground. Plum can not be planted in the shade or near a large tree. Plum feels great in the sun. If she does not have enough light, then she will no longer bear the fruits.
It also happens that in spring, plum trees bloom, but they do not bear fruit and even their ovaries fall to the ground. There may be several reasons for this.
Freezing. When plum blossoms, it is necessary to consider not only the flower itself, but also its pistil. Pay attention to its color. If the pistil is frozen in winter, it will be black.
A healthy pestle is always green. A tree can freeze during flowering, if in the spring there is a decrease in temperature below zero degrees. If the pestle has suffered, then after flowering the fruit will not be tied.Frozen and insufficient pollination can be the cause of poor fruiting plum
Insufficient pollination. Most plum trees are self-pollinated, but if a single tree or several single varieties are planted on the garden plot, the trees may bloom, but the ovaries will not appear. It is better to plant several trees of different varieties.
Unregistered varieties. Variety plums must necessarily fit the natural conditions of the area in which it will be grown. Having bought an exotic variety, the fruit on it can never be waited.
Lack of power. A very common reason that after the flowering does not form the ovary is that the soil is poor in nutrients. Basically in the land is very low in potassium.
And this is the most important element for the formation of ovaries. Therefore, when the plum is three years old, in the fall you need to feed the soil with potassium. A lot of potassium is contained in the ashes.
Varieties and their proper fit
After planting the seedlings do not need to expect that the first fruits will appear immediately. There is a certain termthrough which the plum trees begin to produce fruit.
It depends on the genetic characteristics of the variety and the pollinating variety, as well as on the conditions in which the trees grow.
To understand through how much the tree will give its first fruits, you need to take into account the distinctive features of the variety, which can be combined into three large groups:
- Trees bearing fruit on annual growth. This group includes Canadian, Chinese, Ussuri and American plum varieties. These varieties form powerful shoots, where a large number of new buds are born. For these varieties need to ensure continuous growth of shoots. The stronger the shoots will grow, the faster the tree will give fruit.
- Trees that produce fruit on perennial branches. This type includes varieties that occurred in Western Europe and the south. These are: Peach, Anna Shpet, Hungarian Home. These varieties are important to their crown constantly thinned.
- With an intermediate type of fruiting. The principle here is the following: on one-year growth and on perennial branches. This type includes varieties: Volga Beauty, Memory of Timiryazev, Mirnaya and others. It is important to care for thinning the crown and maintain the growth of shoots.
The first fruits appear when shoots reach a certain number of internodes on the kidneys. To these processes go faster, you can independently shape the crown, cutting out skeletal branches.
Good feeding and timely soil smoothing are required.
What year does the plum begin to bear fruit
If you grow seedlings according to the rules, then plum will begin to bear fruit after 4-5 years after planting. Therefore, when choosing seedlings, they will surely find out what sort they are: self-bearing or self-fruitful.
Starting from this, other saplings of other varieties are bought and matched to each other. It is better opt for self-fruited plum varieties.
Seedlings of each of the varieties are studied before purchase. In terms of their quality, they must correspond to the area of their disembarkation and give a good harvest in group with each other.

When planting a tree, and after receiving the first fruits, many gardeners are beginning to wonder about how many years the plum tree can bear fruit. BUT how many years can it live?
To drain lived as long as possible, seedlings are planted on lighted plots of land in order to get along with several varieties of plums. If for the growth of plum to create favorable conditions and all the time to support them, the harvest can be collected every year.
But in some varieties, productive years alternate with lean. At all, plum tree can produce fruit for up to 20 years. After this age, the tree begins to age, dries out very strongly, and soon simply dies.
What to do?
There are some simple actions, which you can make a good harvest of plums every year. Here are some of them:
- Treating trees, planting new ones is carried out only in the spring.
- About 15 kg of rotted manure or compost, 0.5 kg of superphosphate, some potassium salt, or 1.5 kg of sifted ash are poured into a dug pit for planting a tree.
- In the first three years of life, “vitamins” can be added to the soil near the tree: in the spring, you can add urea or saltpeter, manure, ash.
- If the weather is dry, then plum trees need a lot of water.
- In order for the frosts and the sun not to be too negatively influenced by the trees, you need to whiten and tie the trunks.
- Cracks on the bark are best cleaned and washed with a 2% solution of iron sulphate.
The answer to these simple actions will be stable annual yield of plums.
