Kohi Rabi

Kohl Rabi Seeds

Kohl rabi is one of the quickest and easiest brassicas to grow, producing crisp, succulent swollen stems with a deliciously sweet, mild flavour somewhere between broccoli, cabbage and turnip. Often overlooked, it is a highly rewarding crop for gardens and allotments, maturing in as little as eight to twelve weeks. The tender bulbs are excellent eaten raw in salads and coleslaws, lightly steamed, roasted or added to stir-fries, while the young leaves can also be cooked like kale. With green and purple varieties available, kohl rabi is both an attractive and productive addition to the vegetable garden.

For the best results, kohl rabi seeds can be started indoors during early spring or sown directly outdoors once the soil has warmed. Starting plants in quality Propagation Equipment provides an excellent head start, particularly in cooler parts of the UK. A ROOT!T Heat Mat supplies gentle bottom warmth for rapid, reliable germination, while the ROOT!T 42W LED Grow Light encourages sturdy, compact seedlings with strong root systems before transplanting. Healthy young plants establish quickly and produce uniform, high-quality bulbs.

Once seedlings have developed several true leaves, transplant them into individual pots using premium Growing Mediasuch as Jiffy PRO7 Coco 70/30 or These professional growing media provide excellent drainage, moisture retention and root aeration, encouraging vigorous root development before plants are transferred into fertile vegetable beds, raised beds or containers.

Kohl rabi thrives in fertile, moisture-retentive soil in a sunny position, although it will also tolerate light shade during the warmer months. Regular watering encourages rapid, uninterrupted growth, producing tender, juicy bulbs with outstanding flavour. Most varieties are harvested when they reach golf ball to tennis ball size for the finest eating quality, but successional sowings from spring through summer will provide fresh harvests over many months. Protecting young plants with insect-proof mesh will also help prevent damage from common brassica pests.
