How to grow kohl rabi

Regularly sow kohl rabi seed 1cm deep in rows then thin or transplant seedlings to 15-30cm apart. Choose fertile soil and a sunny site.

Water your kohl rabi plants regularly in dry weather for steady growth - too little water produces woody flesh.

Boost with a general organic fertiliser if needed.

Harvesting kohl rabi

Dig up swollen base stems when still small (golf ball to tennis ball size) and grate into salads or saute. You can also harvest as baby veg and eat the leaves.
