1. Planting time for potherb mustard in northern China

When planting potherb mustard in northern China, it is generally sown from July to September, depending on local temperature changes. In many areas, the temperature is relatively low, so the question of whether the plants can survive must be considered.

2. Planting methods for potherb mustard

1. Land preparation

The soil for planting potherb mustard must be highly fertile. Level the land and form it into strips, and make sure drainage is good as well; the drainage ditch should preferably be one foot wide. The weeds that are cleared out should be taken away promptly.

2. Raising seedlings

Raising potherb mustard seedlings requires fertile soil. Generally, farmyard manure can be used for composting one month before raising seedlings. The soil texture should be fine, and the seeds do not need to be buried very deep, just 2 to 3 cm.

3. Transplanting

Potherb mustard should be transplanted early, with the time controlled to around 8 to 10 a.m. There should be some soil on the transplanted seedlings. When the potherb mustard seedlings grow to about 12 to 15 cm, transplant them. The spacing between transplanted seedlings should be controlled at 20 to 30 cm, and after transplanting, be sure to water well.

4. Fertilizer and water

Fertilizer and water are the decisive factors in the growth of potherb mustard. Fertilization is generally based on applying a mixed phosphorus and potassium fertilizer together with nitrogen fertilizer, with nitrogen fertilizer naturally making up the main component. A certain amount of urea can also be applied in the early stage, but only a small amount of fertilizer should be applied one week after transplanting. More can be applied in the middle stage. Do not apply fertilizer in the half month before harvesting.

Pest and disease control for potherb mustard must be done well, otherwise it can easily cause a reduction in yield.
