Why does not the flowering and plum blossom?
So, the reasons why your plum is not flowering and not fructifying:
- physiological decadence;
- fruitlessness of a tree species;
- presence of infectious diseases in the tree;
- insects - pests;
- features of climate;
- conditions in which the tree is planted.
Physiological downfall, this is a defect, as a result of which the plum ceases to bear fruit. Outwardly, this can be seen when several trees start to bloom simultaneously, while at the same time ovaries appear on them.
But one tree can not provide proper nutrition to all new fruits, and as a result, some of the ovaries fall off. The reason for this is weak roots.
In this case, the fight or prevention with a defect effect will not have. There are cases when the owners of trees form the crown of the plum in such a way that only a part of the ovaries fall apart, but this happens very, very rarely.
Fruitlessness of variety, the very name of the defect speaks for itself. When buying seedlings, the variety was improperly selected, as a result, gardeners for several years unsuccessfully expect from plum fruit.
With the help of insects, by way of cross pollination, the plum can be fertilized. But also this method does not give any guarantee, because insects are active only in good weather. In rain, flowers can not be pollinated.
Therefore it is betterto choose in favor of fruit-bearing varieties that self-pollinate. Among them are:
- Niagara;
- Stanley;
- The Italian Hungarian;
- Anna Shpet;
- Monarch;
- Herman.
Some infectious diseasescan prevent plum trees from bearing fruit. The most common types of infections are:
- Klyasterosporiosis. It is a fungus that affects the tissues of newly-born leaves. The fungus looks like a small spot of a reddish hue, which gradually dies leaving leaves in the holes. The pathogenic fungus, in addition to the leaves, infects branches, trunk and even fruits.
- Gray Fruit Rot. This disease looks like a small gray speck on the fetus. With this disease the flesh of the fetus rot, outwardly noticeable small specks of ash-gray color. The embryo of this disease tolerates winter time on diseased parts of the tree.
Diseases can be avoided if preventive measures are taken. You can burn leaves, rip off infected fruits, and also spray trees with special preparations several times a season.
Plum can stop bearing fruitbecause of the invasion of insect pests. These can be larvae of plumfish sawflies, caterpillars of the stalk-foot plum, caterpillars of plum moth.
These insects eat fruit seeds and fruits. The affected fruits fall from the tree.
It is possible to fight pests by treating trees with chemical compounds, applying fishing belts, digging the earth around the tree.
Plodozhorku can be destroyed with the help of microbial preparations. Inksticitsidy good help from the calf.
Why does not the plum bear fruit? Plum Dumper:
Weather is another factor, because of which the plum can stop bearing fruits. Kidneys after spring thaw may freeze. With temperature jumps and strong wind, pollen sterilization can occur. In severe conditions, the sink is very uncomfortable, but in the heat the plum can dry up.
The conditions for planting trees directly affect their ability to bear fruit.Plums very capricious trees. The ground under the plum should not contain a large concentration of acids.
For neutralization, it is possible to pour ash or slaked lime into the ground. Plum can not be planted in a shade or next to a large tree. Plum feels great in the sun. If she does not have enough light, she will cease to bear fruit.
It also happens thatspring plum trees bloom, but the fruit does not bringand even their ovaries fall to the ground. There may be several reasons for this.
Freezing. When flowering plum, you need to consider not only the flower itself, but also its pestle. Pay attention to its color. If the pestle is frozen in winter, it will be black.
A healthy pestle is always green. The tree can freeze during the flowering period, if in the spring there is a drop in temperature below zero degrees. If the pestle has suffered, then after flowering, the fruits will not become tied.
.Insufficient pollination. Most plum trees self-pollinate, but if a single tree or several varieties are planted on the garden plot, the trees can bloom, but the ovaries do not appear. It is better to plant a few trees of different varieties.
Non-grafted grades. A variety of 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 not wait.
Lack of food. A very common reason that after the flowering the ovaries do not form is that the soil is poor in useful substances. Basically, there is very little potassium in the earth.
And this is the most important element for the formation of ovaries. Therefore, when the plum is three years old, in autumn it is necessary to feed the soil with potassium. A lot of potassium is contained in the ashes.
.Grades and their correct landing
After planting the seedlings, do not expect that the first fruits will immediately appear.There is a certain period, through which plum trees will begin to bear fruit.
It depends on the genetic characteristics of the variety and the pollinating variety, as well as on the conditions in which trees grow.
To understand,through how much the tree will give its first fruits, it is necessary to take into account the distinctive features of the variety, which can be grouped into three large groups:
- Trees that bear fruit on an annual growth. This group includes varieties of Canadian, Chinese, Ussuri and American plum. These varieties form powerful shoots, on which a large number of new buds are born. For these varieties, it is necessary to ensure a continuous growth of shoots. The stronger the shoots grow, the faster the tree will bear fruit.
- Trees yielding fruit on perennial overgrown branches. To this type are the varieties that have occurred in Western Europe and the South. This variety: Peach, Anna Shpet, Hungarian Home. It is important for these varieties that their crown is permanently cut.
- With an intermediate type of fruiting. The principle here is the following: on an annual growth and on perennial branches. This type includes varieties: Volga Beauty, Memory of Timiryazev, Mirny and others. It is important when leaving to slit the crown and maintain the growth of shoots.
The first fruits appear when shoots reacha certain number of internodes on the kidneys. To ensure that these processes go faster you can independently attach the crown shape, carving out skeletal branches.
Required good recharge and timely soil moisture.
.For what year does the plum begin to bear fruit
If you grow seedlings by the rules, thenPlum will begin to bear fruit in 4-5 years after planting. Therefore, when the seedlings are selected, they must know what sort they are: self-fertilizing or self-fertile.
Starting from this, other seedlings of other varieties are purchased and selected for each other. Betterstop your choice on the self-fertilized plum varieties.
Seedlings of each of the varieties are studied before purchase. They should by the qualities correspond to the area of their landing and in a group with each other give a good harvest.

When planting a tree, and after receiving the first fruits, many gardeners begin to wonder about how many years the plum tree can bear fruit. Ahow many years it can live at all?
To drain out as long as possible, the seedlings are planted on lighted patches of land, so that a number of varieties of plums coexist side by side. If you create favorable conditions for the growth of the plum and maintain them all the time, then the harvest can be collected every year.
But in some varieties, the harvest years alternate with poor yields. At all,Plum tree can bear fruit for up to 20 years. After this age, the tree begins to age, very much dries up, and soon just dies.
.What to do?
There are several simple actions, which you can get a good harvest of plums every year. Here are some of them:
- Transplanting trees, planting new trees is carried out only in the spring.
- About 15 kg of rotted manure or compost, kg of superphosphate, a little potassium salt or, kg of sifted ash, are pre-covered in a dug hole for tree planting.
- In the first three years of life in the soil near the tree, you can add "vitamins in the spring to bring urea or nitrate, manure, ashes.
- If the weather is dry, then plum trees need a lot of watering.
- In order to prevent frost and sun from affecting the trees too much, it is necessary to whiten and tie the stems.
- Cracks on the bark are better to clean and rinse with 2% solution of ferrous sulfate.
The answer to these simple actions will bestable annual yield of plums.
