Have you been growing cabbage for years, but instead of delicious heads of cabbage you get “torn” heads that look like burst balls?
It's all about a mistake that almost everyone makes, but no one notices.
Cabbage cracks not because of pests or diseases, but because of your "care". Yes, it is excessive watering at the end of the season that turns heads of cabbage into rotten rags.

The plant actively absorbs water, and the inner leaves grow faster than the outer ones. The outer layer cannot withstand the pressure - a crack is ready.
But how to avoid this? Reduce watering to a minimum 3 weeks before harvesting. If it rains, cover the bed with film on arches.
You can't save already cracked heads of cabbage, but you can slow down the process: take a shovel and slightly trim the roots on one side. This will disrupt the moisture supply and stop growth.
Never feed cabbage with nitrogen after the head has formed - this provokes “explosive” growth.
Instead of manure, use an infusion of wood ash (2 cups per 10 liters of water) - potassium will strengthen the leaves.
If the cabbage grows in the sun, shade it with a net: stress from the heat increases thirst.
Varieties with dense heads (for example, "Agressor" or "Menza") crack less often, but require strict watering control.
After harvesting, store the cabbage in the basement, wrapped in newspapers - this way it will remain juicy until spring.
Now you know that the secret to perfect heads of cabbage is not in fertilizers, but in knowing when to stop.
