Growing Brassicas From Seeds

Cabbages, kale, kohlrabi, cauliflower, broccoli and Brussel Sprouts are all varieties of the same species of Brassica oleracea which is native to the Mediterranean. Brassicas thrive on transplanting and some gardeners even swear by transplanting them twice.

  • For Brussel Sprouts sow the seeds in March early April
  • For 'Spring Cabbage' make two sowings 4 weeks apart in February
  • For Summer Cabbage sow in March
  • For Winter Cabbage sow in May
  • For Summer Cauliflower sow in March
  • For Broccoli sow in April

Deep Rootrainers make an excellent start when growing from seed, just fill with compost (preferrably peat free) and cover with a clear propagating lid and leave to germinate in a warm place.

Haxnicks Plant House

Once plants start emerging use as a drip tray under the tray and grow on in a good strong light place, A Haxnicks Hardwood Plant House situated on a sunny wall is an excellent place.

When plants are ready plant out into a deep, rich well composted and moist soil. Make 15cm deep holes with a garden stake and place the seedling into the hole. Don’t close the hole with soil but rather water the plant which will close the hole with the right amount of soil.

Watering of the young plants is vital until they are well established and weeding is just as essential.

If pests are a problem or you want to bring on growth a little quicker then we do recommend our Victorian Cloches, these provide instant weather protection and additional warmth for faster growth.
