In winter, due to the cold weather and temperature characteristics, there are certain requirements for the growth environment of vegetables. Some vegetables are not suitable for planting in winter if they are not cold-tolerant, and planting vegetables in the wrong season in winter will be more challenging.
Growing vegetables in any season has advantages and disadvantages, and so does winter. As we all know, the weather is getting colder and colder in winter, and the temperature in some places will be very low. It is very important to know the matters needing attention in winter planting, so as to carry out effective prevention in the planting process and ensure the quality and yield of vegetables, especially for people who are full-time vegetable maintenance.
Pay attention to prevent freezing injury when planting in winter. It snows in many places at the end of winter, and it is common for the outdoor temperature to reach several degrees below zero. Vegetables are easily frostbitten in such temperature conditions.
In order to prevent the occurrence of dead seedlings, appropriate heat preservation measures should be taken when the temperature is low in winter, but it is not good to have a high temperature in the greenhouse, and the temperature in the greenhouse is high and the ventilation is poor.
Cold-tolerant vegetables:
1, broccoli
Broccoli can tolerate the low temperature of MINUS 2 to 3 degrees. If you raise seedlings indoors, you can raise seedlings as early as 10 ~ 12 weeks before the end of frost period, and then transplant them into the garden about 4 ~ 6 weeks before the end of frost period, which can increase the vegetable planting time by about 2 months every year.
2. Brussels sprouts.
Its cold tolerance is also very strong. Generally speaking, the tolerable temperature is around zero.
3. Vegetable cabbage.
Cabbage can tolerate the lowest temperature of MINUS three degrees.
4. kale.
Kale can withstand the lowest temperature of -7 to 10 degrees, and it is a very cold-resistant vegetable. Kale is not only resistant to low temperature, but also not as easy to get sick as other vegetables.
5. Bulb cabbage.
Bulb cabbage likes this cool climate very much. Generally speaking, it is transplanted about four to six weeks before the end of the middle frost, so its seedling raising time is similar to that of Brussels sprouts and broccoli mentioned above, about 10 to 12 weeks.
