When is the best time to plant northern kale?

1. Different varieties have different sowing dates. Early maturing varieties such as Hong Kong white kale and willow early kale were sown from mid-April to early August.

2. Sow mid-late mustard and other mid-late varieties from September to March next year, and ensure the supply of 1 1 month to May next year. It should be noted that it is hot in the north from July to September, so it is appropriate to choose a cool place for planting.
