Kohl Rabi Plants FAQs

Take a look at some of the frequently asked questions we receive from those looking to buy Kohl Rabi Plants in the UK. You can  contact our Customer Service Team or browse our general FAQs for further advice.

When to plant Kohl Rabi Plants

The best time to plant kohl rabi plants in the UK is in early spring, from March to April, or in late summer for a late autumn harvest (around August to September). Kohl rabi prefers cooler temperatures, so spring planting will allow the plants to grow before the summer heat sets in. If you’re planting for an autumn harvest, sow seeds indoors in late summer, then transplant them outdoors once the risk of frost has passed.

How to Plant Kohl Rabi Plants

To plant kohl rabi plants, choose a sunny spot with well-drained, fertile soil that is rich in organic matter. Sow seeds directly into the soil in early spring or late summer, about 1 cm deep and 15–20 cm apart in rows. If starting seeds indoors, sow them 6–8 weeks before the last frost and transplant them outside once they are around 8–10 cm tall and the weather is consistently warm. Space the plants about 30 cm apart to allow enough room for their bulbs to develop. Keep the soil consistently moist but not waterlogged, and consider mulching to retain moisture and prevent weeds. Kohl rabi grows best in cooler weather, so avoid planting too late in the season to prevent bolting.

How long do Kohl Rabi Plants take to grow

Kohl rabi plants typically take around 8 to 10 weeks to grow from planting to harvest, depending on the variety and growing conditions. If starting from seeds, you can expect the plants to be ready for harvest about 2 to 3 months after sowing. For best results, harvest the bulbs when they are 7 to 10 cm in diameter, as they are tender and flavourful at this size. Harvesting too late can result in tough, woody bulbs.
