Growing berries on the backyard has long become a habit. But the cultivation of unusual, rare species causes, first of all, interest or even excitement. After all, who does not want to admire a beautiful bush with rare, tasty and healthy berries. But such shrubs are a risk. After all, even after the maximum effort, they do not please with the harvest. Why blueberry plantings do not bear fruit and what to do so that the plant begins to produce a crop.

Why blueberries do not bear fruit and bloom: causes and solutions to the problem

Situations arise when, with all efforts to care for blueberries, flowering and fruiting does not occur. To understand why garden blueberries do not bloom, you need to observe the plant. Mistakes may have been made when landing or leaving. And there are enough factors affecting the fruiting of a bush.

Violation of agricultural technology

An important factor in the appearance of flowers and the fruiting of a plant is the observance of the rules of agricultural technology. This shrub grows poorly in the beds where there were previously potatoes or other vegetables. Herbs, moreover, perennial ones, are recognized as the best predecessors. The plant does not like organic matter, so soils are suitable, in which organic matter has not been introduced for the last five seasons.

Failure to comply with the rules for planting a plant is also an important factor. When buying, you must choose a copy that is in a large capacity. In small pots, the roots of the plant are densely intertwined, rolled inward.

Shrub planting rules:

  1. Soak the container with blueberries for a quarter of an hour.
  2. Remove the pot, straighten the roots of the plant, since they themselves will not straighten. If planted as it is, then after a while, when digging up, it will be found that the root system has remained in the same form. Blueberries planted in this way will not only not bear fruit, but will die over time.

The root system of the shrub is shallow, practically in the surface layer, not deeper than 0.25 m. Accordingly, a hoe or similar equipment is not used in the process of weeding the plant. The damaged root system will not heal. The earth is not loosened deeply, by 30-35 mm.

Planting bushes in the shade

The shrub does not bloom if planted in a shaded area. Although this is a familiar environment for him and he takes root well in the shade, the plant needs light for fruiting. In this case, the place should be illuminated by the rays of the sun, protected from the through wind.

Unsuitable soil acidity

The acidity level should be up to 3.5-4.5. To obtain such a soil, it is recommended to use sulfur or sulfuric acid. And to acidify the soil, you can use 9% acetic or malic acid at a rate of 120 ml per 10 liters of liquid.

No mulch

Mulching with sawdust, bark and needles of trees contributes to the enrichment of the soil, creates an air-water balance for the development of the root system of the plant, helps maintain the required level of acidity, and prevents the appearance of weeds. The recommended layer thickness is 5-8 cm.

Mulching has been proven to promote plant growth and yield. One of the advantages of mulch is the ability to retain moisture, coolness of the soil in hot weather and warmth during winter (the roots are preserved from frostbite).

Insufficient drainage

If the ground is heavy and the groundwater is not far away, it is necessary to plant blueberries on the ridge. It is required to extract a part of the soil 50-80 mm deep. Spread it out in a circle of the landing hole. Fill the pit with peat or peat-sand mixture. You can add sawdust, needles. You should get a hump, on the top of which place a blueberry bush, sprinkle with soil, and mulch the soil.

As a result, excess liquid will flow down the surface of the slide, and the plant's root system will receive air and water in a balanced manner.

Planting only one bush

To improve yield indicators, it is recommended to plant at least two varieties of blueberries, then there will be a lot of berries.

Bacterial and infectious diseases

A diseased plant weakened by infectious or bacterial diseases will not bear fruit. For prophylaxis, it is recommended to treat it with fungicides in the spring and autumn.

At the beginning of spring, it is treated with "Polycarbacin" 1%, Bordeaux liquid, "Rovral" 1%. When the foliage blooms, treat it with a fungicide (Topsin M, Euparen, Kuprozan, Benomil, Rovral). Processing is carried out three times in 7-10 days.

After removing the berries from the bush, three times are treated with fungicides, the last after the foliage has fallen.

Double leaf spot

Appears exclusively on sheet plates. At the end of March, a small number of small light, brown, gray, dark spots with a diameter of 2-3 mm are formed, but soon there are more of them. In summer, the formations begin to expand, reaching a diameter of 6 to 13 mm. The spot becomes, as it were, double: the previous and the new, much darker. In rainy weather, the disease spreads much faster.

Topsin and Euparen are recognized as an effective drug for treatment. In spring and autumn, it can be processed with "Rovral".

Stem cancer

The most harmful disease of this nature. The disease has the following symptoms. First, red spots are formed on the scars of the leaf plates, on the shoots. Over time, they get larger, take on the shape of an oval and darken. Further, the spots grow, connect with each other, cover the entire surface of the shoot, and its dying off occurs. Young shrubs are more quickly affected by this disease. On old shoots, ulcers appear with cracked and falling off the bark.

First of all, prevention is important. It is not recommended to plant in beds where there is high humidity, not to apply a large amount of nitrogen-containing fertilizers. Timely cut off the branches damaged by the disease and destroy them.

For treatment, it is recommended to use Topsin (0.2%), Euparen. Carry out the processing three times, every 7 days. The first treatment is before flowering, the second after harvest. Treat with Bordeaux liquid after foliage bloom, in autumn - twice after falling off.

Parasitizing the fungus phomopsis

The symptoms are similar to stem cancer. New shoots begin to dry out and curl up. The length of the lesion varies from 3 to 35 cm. The foliage becomes brown, dries up, falls off, and red spots 10 mm in diameter are formed on it.

To fight, it is necessary to destroy the affected shoots, the plant is treated with drugs used in the treatment of stem cancer.

Gray rot

The disease is characterized by lesions with brown, sometimes red spots on branches, leaves, and fruits. Subsequently, the spots become gray. The spread of the disease begins from the top of the shoot and moves to the base. The berries suffer greatly. Especially dangerous in prolonged wet weather. When the spores of the fungus get on the flowers, the yield decreases.

Plants overfed with nitrogen, as well as thickened plantings with poor ventilation, are susceptible to this disease..

The fungus hibernates on fallen leaves. All foliage and fallen fruits must be collected and burned. The preventive methods used for the diseases mentioned above are important. It is also recommended to plant the bushes at a sufficient distance to allow air circulation.

Moniliosis of fetuses

Visually, this disease looks as if all parts of the plant: branches, leaf plates, flowers and fruits, are beaten by frost. The fungus hibernates in dried berries. First, the affected branch tip withers, turns yellow, after which it acquires a brown tint, blackens and dies. At this stage, it is called "monilial burn". Flowers also turn brown and die. The berries acquire a brown hue and lose their taste.

Gradually, the fungus covers the wood, the bark cracks, gum deposits appear, gradually the branches of the plant die off.

For prevention and treatment, it is necessary to collect all the fallen debris under the bush and burn it. It is recommended to spray with Bordeaux liquid or other fungicides.

Viral lesions

Fungal diseases are not the only ailments that plague the plant. Some of them are viral. When affected by a similar disease, treatment is useless. It remains only to remove and burn the affected plant. It is important to learn to identify the nature of the disease.


Yellowish patterns are formed on the leaf plates of the plant. They are yellow near the cuttings, greenish closer to the tops. The disease is carried by ticks.

Filamentous branches

The complexity and danger of this disease lies in the fact that in a latent state it can last for about four years. When damaged, the growth rate of the plant decreases, the leaf plates turn red, then wrinkle, curling gradually begins. Stripes similar to laces are visible on the sprouts.

Red ring spot

By the middle of summer, reddish spots form on the leaf plates of the plant, often on old ones. The defeat begins with the leaves and gradually spreads to the entire plant, completely destroying it.


This disease is caused by mycoplasma. A diseased plant grows poorly, hence the name. Small, tasteless berries are tied on the branches, or there are none at all. Gradually, the leaves become small, then turn yellow, and at the end of summer, the yellowed leaves turn red.

Necrotic spotting

With this disease, red spots of a ring shape are visible on the leaves of the plant. First, the lesion spreads to old leaves. After that, the plant is completely affected.

There are a lot of reasons for the slow development of the bush and the lack of berries. If this is a violation of the rules of planting or care agrotechnology, this can be corrected in a fairly short time. If the plant is affected by an ailment, you will have to spend a lot of time and effort to save it. If the disease is viral, the plant cannot be saved. The main thing is to correctly and in time to determine the cause of the current situation and, without delay, try to save the plant. Only then can the desired results be expected.
