    Growing Instructions:

    Broccoli seeds can be sown directly into the garden but perform best transplanted. Start broccoli seeds indoors 6 weeks before the last frost in your area. Follow the seed depth and spacing guidelines indicated below. Once all danger of frost has passed, seedlings should be hardened off before planting in their growing location. Seedlings should be transplanted according to the plant and row spacing directions below. Regularly monitor your plants and ensure that the soil remains moist, but not soggy while they establish themselves in their new environment.

  • Plant Spacing: 30 cm (12")
  • Row Spacing: 30-35 cm (12-14")

  • Instructions for Nutrient Care: Feed plants SUPERthrive once per week. Mix 1.2 ml (1/4 tsp) per 4L (1 gallon) of water in a watering can and apply solution to the base of the plants.
Suggestions Chevron Down Chevron Forward
Growing Suggestions:
  • Broccoli grows best in temperatures from 18-24°C (65-75° F).
  • Broccoli has a shallow root system. Be careful when cultivating the ground near the plants to not disturb the roots.
  • High temperatures and increased day length can cause broccoli plants to bolt. Bolting refers to premature seed or flower stalk production before the harvest of the vegetable and typically renders the crop unusable.
  • Cut the main head and you will likely harvest a good-sized secondary head a little later.
  • Plant brassicas together so they can all be covered with netting to protect them from pests such as cabbage worms.
