What to Do When Cabbage Bolts? Detailed Explanation of Causes and Prevention Methods
Cabbage is one of the important vegetables in China and is widely grown across the country, and spring is the best time to plant cabbage, but during planting, cabbage bolting can occur, leading to reduced cabbage yields and affecting profits. So what causes cabbage bolting? How should it be prevented? Let's find out together.
1. Improper variety selection
There are many cabbage varieties, and different varieties have different characteristics. Some varieties are strongly winter-hardy, while others are weakly winter-hardy, so their bolting rates also differ. Generally, varieties with weak winter hardiness bolt very easily, while varieties with strong winter hardiness have a low bolting rate.
Prevention method: Therefore, when selecting varieties, choose those with strong winter hardiness to reduce the early bolting rate and increase yield.
2. Improper sowing time
The sowing time of cabbage can also affect its bolting rate to a certain extent. If sowing is too early, the seeds remain in a low-temperature environment for a long time, and once the temperature rises, bolting is very likely to occur.
Prevention method: Strictly control the sowing time. Cabbage is a low-temperature vernalization plant, and in a prolonged low-temperature environment, it will bolt very easily. Many people sow blindly in order to increase yield, which instead has the opposite effect. When sowing, choose October to November as the most suitable period according to local climatic conditions.
3. Unsuitable temperature
During the cabbage seedling stage, if the temperature is too high, even if it is applied at the right time, it will cause the seedlings to grow rapidly, and when transplanting is done, the accumulated temperature will also be completed, resulting in bolting.
Prevention method: Temperature must be well controlled. When the temperature is too high and the seedlings are growing vigorously, the development of the seedlings can be controlled to inhibit their growth, so as to prevent the seedlings from growing too large during overwintering and bolting after spring.
4. Improper transplanting time
If the plants are too large when the seedlings are transplanted, bolting is likely to occur during overwintering. At the same time, the transplanting time is also extremely important. If transplanting is too early, the seedlings are exposed to low temperatures for a long time and bolting may occur; if transplanting is too late, the low-temperature duration required by the seedlings cannot be met, and bolting will also occur.
Prevention method: When transplanting, be sure to control the transplanting time and the size of the seedlings well. After transplanting, reasonably regulate fertilizer and water according to seedling size, so that they can overwinter smoothly without bolting.
