Regular watering is essential.
It is a big disappointment when, after cutting the kohlrabi, you see that the tuber is woody and fibrous and therefore hardly enjoyable. Woodiness is the result of cultivation errors and stress on the vegetable.
Possible stress factors include drought, too little space, compacted soil and too deep planting. Therefore, during the growing season, ensure the proper growing conditions and regular water supply. On the other hand, too much water given at the same time and large fluctuations in the moisture supply will cause the tubers to crack.
A regular and even water supply is also important because this vegetable has shallow roots. The growing time of kohlrabi will increase if it does not receive enough water and will become woody. The kohlrabi harvested too late will also be woody; the earlier you harvest, the tenderer and juicier it will be.
Woodiness begins in the lower part of the tuber, so you can check here with a knife: if it penetrates the tuber without resistance, the plant is not woody.
Regular, small doses of fertilization are more beneficial for kohlrabi during the growing season than a single large dose. If it is planted in a mixed culture, it is a good companion plant with bush beans, green peas, Swiss chard, lettuce, spinach, pot marigold (Calendula) and African marigold (Tagetes).
