Growing cabbage is a real art that requires attention and knowledge.
One of the main problems that gardeners face is the cracking of cabbage heads.
Causes of Cabbage Cracking
Cabbage heads crack for several reasons. The main factor is uneven watering.
When, after a long drought, a plant receives excess moisture, it begins to actively absorb water.
The inner layers of the head of cabbage grow faster than the outer ones, which leads to the formation of cracks.
Another reason is improper fertilization. Excess nitrogen stimulates rapid growth, which is why the outer leaves do not keep up with the inner ones.
Cracking is also influenced by sudden temperature changes and mechanical damage.
Prevention of cracking
Regular watering is the key to success. It is necessary to maintain constant soil moisture, especially during the period of head formation.
It is recommended to water the cabbage once every 3-4 days, preventing the soil from drying out.
Mulching helps to retain moisture and prevent the soil from overheating. Straw, mown grass or special materials can be used as mulch.
Proper fertilization also plays an important role. At the beginning of the season, cabbage needs nitrogen, but as the head grows, you should switch to potassium-phosphorus fertilizers. This will slow down growth and strengthen the plant tissue.
Selection of resistant varieties
There are varieties of cabbage that are less prone to cracking. When choosing seeds, it is worth paying attention to such characteristics as resistance to cracking and shelf life.
Popular resistant varieties include 'Atria', 'Valentina' and 'Megaton'.
Measures to take when the first signs appear
If small cracks appear on the head of cabbage, you can take emergency measures. Lift the plant slightly by digging under it on one side.
This will limit the supply of water and nutrients, slowing growth.
Another method is root cutting. Use a shovel to make a shallow cut into the root system on both sides of the plant. This will also slow growth and prevent further cracking.
Timely harvesting
It is important not to miss the moment of technical ripeness of cabbage. Overripe heads of cabbage are more prone to cracking.
Signs of readiness for harvesting: density of the head, characteristic crunch when pressed and slight whitening of the upper leaves.
Proper storage
After harvesting, it is important to ensure proper storage conditions. The optimum temperature is from 0 to +1°C with air humidity of 90-95%.
It is better to store cabbage in boxes or on shelves, avoiding contact between heads of cabbage.
