The planting time of Brussels sprouts depends on the planting method and variety. If planted in the open field, early-maturing varieties should be selected, and sowing should be carried out from late July to early August. If planted in protected areas, early-maturing and middle-maturing varieties should be selected and sown in late July to early September. It is best to sow late-maturing varieties early, and early-maturing varieties should be sown late.

Second, how to grow Brussels sprouts

1. Prepare seedbed: When sowing, select the plot where cruciferous vegetables have not been planted for nearly three years, first fertilize and prepare the soil to ensure that the plot is loose and fertile, and apply decomposed fertilizer and compound fertilizer.

2. Seeding method: After the seedbed is treated, you can sprinkle the prepared seeds on it and sow directly. Pay attention to the planting density. Use 25 grams of seeds per mu.

3. Post-planting management: After the seeds are planted, a layer of soil should be covered in time, and the bed surface should be covered with a sunshade net and watered once to ensure that the border surface is moist. When the seedlings begin to appear, take off the sunshade net.

4. Seedling management: When the seedlings grow two true leaves, divide the seedlings in time, and the area of the transplanted seedbed should be large enough, which is 10 times that of the existing seedbed. When raising seedlings, apply nitrogen fertilizer in time, water regularly and keep moisture. After the rainy day, drain the accumulated water. In addition, attention should be paid to the prevention and control of pests and diseases.
