What to do if hazelnuts do not bear fruit?
In nature, hazel grows in the forest more often and bears fruit well. At the same time, for many gardeners, hazelnuts serve as a wonderful decoration of the site, grows to large sizes, blooms, but does not bear fruit. To solve this problem, it is necessary, first of all, to determine the reasons that can provoke the absence of nuts on hazel.
Why doesn’t the fruit bear the nut, and what should I do?
The absence of fruiting of hazel is caused by such factors:
- low fertility of seedlings;
- wrong choice of seedling variety;
- poorly selected landing site;
- the use of nitrogen as a fertilizer;
- overgrown basal shoots;
- return frosts;
- drought, especially during flowering.
To fix problems with fruiting hazelnuts, there are such methods:
- picking or pinching shoots up to 15 cm long;
- blinding of the kidneys in places where the growth of shoulder straps is undesirable;
- control the orientation of the branches in space;
- anti-aging pruning;
- shelter for the winter.
Incorrect landing of hazel
In order for hazelnuts to bear fruit well, for each region you need to choose your own kind of hazel, which will perfectly tolerate climatic conditions. Most often, the plant suffers during flowering from return frosts that cause the flowers to freeze completely.
Therefore, for regions with a cold climate, it is worth choosing varieties that bloom at a later date. For the southern regions, it is better to choose plants with an early flowering period, which will allow hazel to grow nuts before the onset of a dry period.
Important! Healthy hazel bushes, which are planted vegetatively, should bear fruit in the 4th year of life, and grown from seedlings in the 8th year.
Improper hazel care
Hazel fertilizer should not contain a lot of nitrogen. This substance accelerates the growth of the green mass of the bush, inhibiting its bearing. The growth of hazel, not related to fertilizer, also negatively affects the formation of nuts, so it is important to trim the hazelnuts in time, supporting the inside of the bush. Young branches should not be pruned, because the nut bears fruit on them. A huge amount of root growth greatly depletes the shrub, so you need to get rid of it.

Winter hazel freezing
Negative frosts negatively affect hazel.The fruits die if the air temperature drops to –3 ° C during flowering. At the same time, significant frosts down to –30 ° C do not negatively affect the plant. Pollution is prevented by prolonged rains during flowering, which prevent pollen from spreading.
Such measures will help prevent freezing of hazel during flowering in early spring:
- Conducting small drip sprinkling at night in the event of a drop in air temperature to –4 ° С.
- Creating a curtain of smoke over the bush, which will help in the absence of wind to raise the temperature by an average of 2 ° C.
- Spraying the crown with fertilizers 2 hours before the onset of frost.
- Winding the bush with covering material.
Rejuvenating pruning of the shrub, which is the elimination of all old branches, will help prevent poor fruiting. In their place, after a while, new ones grow. This procedure must be performed every 5 years.It is important that the branches of the plant are correctly oriented in space and not obscure each other. To do this, in the early spring before lignification of young shoots, they are bent to the ground and tied with a rope to stakes driven into the ground.
Another way to increase the yield of hazelnuts is to mulch the trunk circle to retain moisture and increase soil fertility. The absence of fruiting of hazelnuts can be due to various reasons associated with improper planting, care or freezing of the plant. In this case, the shrub can look healthy and have a well-developed crown. For the appearance of fruits, it is necessary to identify and eliminate the cause that prevents the plant from bearing fruit.
