Hi, my kohl rabi have failed to form the swollen tuber. They are 30cm tall and long stems, have been in the ground for 10 weeks, planted out from seedlings I raised myself and look really healthy. In raised garden bed, full sun, new soil and surrounded by successful snow peas, lettuce, broad beans and radish crops. What have I done wrong ?
