Why raspberries don't want to grow, what to do if they bloom but don't bear fruit

When growing raspberries, gardeners sometimes make mistakes. When this happens, yields can drop tenfold. To prevent this from happening, it's important to understand why raspberries aren't growing and take this into account. If this happens, analyze the mistakes made and correct them in future work.

The main reasons for the lack of fruit on raspberries

There are many such reasons. The main ones are listed below.

Agricultural technology errors

One of the important conditions for obtaining a good harvest is the correct choice of the cultivated variety. If the variety is old and traditionally produces a low yield, then you should consider using a more productive variety.

The following varieties are in demand:

• Peresvet;
• Lazarevskaya;
• Shosha;
• Patricia;
• Arbat.

They allow you to consistently grow a harvest of no less than 2-3 kg from each bush.

Another potential problem is the lack of trellis support when growing the plant. Using a trellis can increase yields by 6-8 times. The berries will also be juicier and larger.

It's recommended to grow raspberries in beds 30 cm wide, with some space between them. Some grow raspberries in wide strips, allowing them to become overgrown with weeds. This can be one reason for reduced yields.

Raspberries sprout easily. Excessive shoots should be controlled. For example, they can be used to propagate the bushes or removed. This ensures that the raspberry bushes receive adequate sunlight not only at the top but throughout their entire height. This will allow for more berries to be produced. Furthermore, the stems will be better exposed to wind, which can reduce their moisture content. Under these conditions, the likelihood of fungal growth is significantly reduced.

Removing the lower branches will help in the fight against the raspberry mosquito.

Remembering to thin the bush will help increase the yield. It's believed that this will produce 1.5-2 times more berries. Raspberries are a plant that requires constant nutrition. Insufficient nutrition immediately affects the plant's health.

An overgrown raspberry patch

Raspberries have a biological characteristic that they don't develop over time. However, some areas look neglected and are overgrown with barren flowers. When grown this way, the bushes become weakened and susceptible to disease. If you tidy up and maintain your raspberry patch, high yields are quite possible.

Weeds need to be removed, debris cleared, and bushes need to be staked or trellised. After this, you can expect the bush to return to normal fruiting.

Drought at the time of ovary formation

If the fruit doesn't set, there won't be any berries. Severe drought during this period can cause yields to drop. To prevent this, adequate watering is necessary during this time.

Deadwood

The plant's roots are located close to the soil surface. In the sun, the soil dries out quickly, which is detrimental to the plant. This situation can lead to the raspberry lacking moisture. It is believed that overdrying the soil can reduce yield by up to three times.

The soil has become very compacted.

Failure to loosen the soil after rain or watering will result in raspberries failing to produce a harvest. Therefore, after precipitation and watering, it is necessary to loosen the soil. Mulching will prevent this problem.

Ant invasion

If a shrub blooms but doesn't bear fruit, it's likely damaged by ants. They usually herd aphids. To get rid of them, use specialized pesticides, available at a specialist store.

How to restore fruiting

Some gardeners yield up to 8 kg of raspberries per bush. However, even if they only manage to harvest 3 kg of raspberries, this is considered normal. However, if the yield has decreased, it's most likely due to growing errors.

To restore fruiting, you need to do it as prescribed by the growing rules.
