WeedingNo published guide covers this for the North-east hills and valleys, so this is an AI suggestion. Check it with local advice before you rely on it.

Weed by hand two or three times in the first month after transplanting. A mulch of dry grass or leaves keeps weeds down and the soil moist.

    • Cover young plants with fine net

  • Disease

    Black rot

    Signs

    V-shaped yellow patches from the leaf edges, with dark veins.

    Prevention

    • Use seed from healthy plants
    • Rotate with crops outside the cabbage family
    • Destroy crop debris after the last picking

  • Disease

    Damping off

    Signs

    Seedlings in the nursery fall over and die at soil level.

    Prevention

    • Do not overwater the nursery

Seed and the season's end

Saving seedNo published guide covers this for the North-east hills and valleys, so this is an AI suggestion. Check it with local advice before you rely on it.

Keep a few healthy, true-to-type plants over winter and let them flower in spring. Keep them well away from other cabbage-family crops in flower, or they will cross.

When the seed is ready

Pods turn yellow-brown and dry, and the seed inside turns dark.

Cleaning the seed

Cut the seed stalks as the pods dry, dry them in shade for a few days, then thresh and clean the seed.

Store dry seed in a sealed container in a cool, dark place. It keeps well for about three years.

After the last pickingNo published guide covers this for the North-east hills and valleys, so this is an AI suggestion. Check it with local advice before you rely on it.

Pull the plants when they bolt in spring, compost them, and follow with a crop outside the cabbage family.

Pull the old plants once they bolt and compost them. Burn or bury plants that showed black rot rather than composting them.

Rotation

Do not follow with another cabbage-family crop for two to three years. Peas, beans, onion or a summer cucurbit are good next crops.
