When to sow: Feb – Aug
Spacing: 30 x 15-30cm
Kohlrabi tips: Direct sow in 1cm deep drills 30cm apart from the end of February right through till August, thin to final spacing. Early sowings should be protected with fleece or cloches.
Alternatively sow in modules and plant out to final spacing.
Sow every two weeks for a continuous supply.
Purple varieties are generally hardier and better suited to very early crops.
