Why do grapes crack and burst?

The saddest sight in the vineyards is a spoiled harvest of ripe, cracked berries. This problem affects both novice and experienced gardeners. And everyone asks: why do grapes burst?

The main reasons for grape cracking include:

Humidity level

In nature, everything is cyclical: the period of drought gives way to the rainy season. Due to a lack of moisture, grape bushes actively absorb water, and the berries quickly fill out. Such an abundance of moisture negatively impacts the taste of the fruit. The skin cells don't have time to form quickly, causing the grapes to burst.

The easiest way to solve this problem is to properly water the berries throughout the growing season. Regularly moistening the soil will prevent the plants from absorbing moisture as readily after rainfall. Consequently, the berries will not crack.

Feature of the variety

Are you following all the gardening guidelines, but your grapes are still cracking? Please note that certain grape varieties (including Izyuminka, Laura, Krasotka, Kishmish Zaporizhzhya, Prozrachny, Snegir, and others) are prone to cracking during ripening. Proper watering, fertilizing, loosening the soil, and insect control are all ineffective. The only solution, according to farmers, is to harvest the grapes earlier.

Incorrect feeding

During flowering and vegetation, plants need fertilizers.

However, don't overdo it, as too much fertilizer is just as harmful as too little. Excess nitrogen causes fruit spoilage, and the skins crack, unable to keep up with the rapidly growing berries. At this time, you can add a little potassium and phosphorus, which help increase the elasticity of the skins. This will preserve your harvest and prevent the grapes from bursting.

Diseases

According to gardeners, ripe berries will crack due to disease. The most common diseases affecting this plant include chlorosis, vascular necrosis, powdery mildew, and oidium.

To prevent fruit from cracking, remember to inspect your bushes for signs of disease or insect pests. Timely garden maintenance is the key to a bountiful harvest.
