What is the best time to plant kohlrabi and how long is its growth cycle?

When to plant kohlrabi

Kohlrabi is usually grown in most parts of the north and can be cultivated in both spring and autumn. In spring, it is generally sown in early to mid-February, transplanted in mid-April, and harvested in May to June. If you choose to sow in autumn, it is sown in late July, transplanted in mid-to-late August, and harvested in mid-to-late October.

The growth cycle of kohlrabi

The growth period of kohlrabi is about two years, and the cycle can be divided into two stages: the vegetative growth period and the reproductive growth period. The vegetative growth period can be divided into five growth periods, namely, the germination period, the seedling period, the rosette period, the heading period and the dormancy period.

How to grow kohlrabi

1. Variety selection

Early-maturing kohlrabi varieties should be selected for spring cultivation, and kohlrabi varieties with strong adaptability and good quality should be selected for autumn cultivation. Selecting the corresponding varieties according to the conditions of the planting site and the planting time can greatly increase the yield.

2. Cultivate strong seedlings

You can grow seedlings in a greenhouse with sunlight, mix the fertilized soil evenly, sieve it, put it into nutrient pots, arrange the nutrient pots in the seedbed, water them sufficiently before sowing, wait for the water to seep in before sowing, cover them with plastic film after sowing to keep warm and moist, and remove the plastic film after the seedlings emerge.
