Post category: Lettuce
Greenhouse-grown lettuce is of better quality than outdoor crops and it is available from November to May when they are not. Sow the variety ‘Kwiek’ in late August for winter lettuce, and ‘Emerald’ and ‘Kloek’ in September/ October for late winter and spring supplies.
These varieties tolerate cold weather, but without frost protection at least, there can be some losses and the plants will not ‘heart’ up. Watch for greenflies. Do not splash water about or grey mould will attack some of the plants at soil level. Lettuce can also be grown in frames or in low tunnels.
