Four Reasons Why Grapes Dry Instead of Ripening 0 2233

Let’s consider four reasons why grapes may dry instead of ripening.

1. Overloading the Harvest

When a large number of clusters form on the grapevine, gardeners hope for an excellent harvest. However, this is not always so simple.

If there are many set fruits on the bushes, the grapes may not have enough nutrients for full development.

As a result, some clusters begin to dry out, and excess berries drop off. Usually, the set fruits dry before ripening, but there are exceptions. This process can be considered natural, as the bushes self-regulate the amount of harvest.

This problem most often occurs in young bushes, which have not yet developed a strong root system. To avoid this situation, it is recommended to remove excess set fruits and shoots in advance, although this may be difficult for the gardener.

2. Violations of Care Rules

For the proper development of grapes, three conditions must be met:

1. Regular and proper watering.

2. Application of nutrients.

3. Moderate sunlight exposure.

During prolonged drought, grapes may reduce the amount of harvest. It is especially important to pay attention to watering young bushes, which have a poorly developed root system, as a lack of moisture can be critical.

Sunburns are also possible. If the grapes lack green mass, the likelihood of sunburn increases, which can lead to the complete drying of the cluster.

3. Lack of Nutrients

The absence of spring, summer, and autumn fertilization can cause the aforementioned problems.

Grapes require regular fertilization, and even the lack of fertilizers for just one season can lead to negative consequences.

4. Damage from Diseases and Pests

Grapes can be susceptible to the following diseases:

1. Downy mildew.

2. Drying disease.

3. Anthracnose.

4. Verticillium wilt.

These diseases develop quickly and can spread throughout the plantation in a season. To avoid diseases, it is necessary to regularly inspect the bushes and carry out preventive treatments.

Dangerous pests of grapes include:

• spider mite;

• wasps;

• underground phylloxera.

The fight should begin with wasps, which can cause serious damage. For this, traps can be set up and nests located on the site can be destroyed.
