Cauliflower Succession Planting & Season Extension

Johnny's Planting Programs are designed to take the guesswork out of succession planting, allowing you to easily extend your harvest throughout the growing season.

Successive plantings of different cauliflower varieties in the appropriate seasonal slots and sequence will allow you to maximize your yield, quality, and harvest window. Choose from a dozen cauliflower varieties by type, days-to-maturity, heat and cold tolerance, color, and optimal sowing/harvesting periods.

Exposure to the sun can cause the heads of white cauliflower varieties to turn yellow or light purple. Blanching is a simple technique that results in the creamy-white heads many people look for in cauliflower. Follow these simple tips for uniformly white heads.

  • The time to begin blanching is when the developing heads are just visible through the leaves, about 1–2" in diameter.
  • Gather the outer wrapper leaves and pull them over the heads, securing them together with twine, clothespins, or a rubber band.
  • Another method is to crack the midribs of the leaves and fold them over the head until it is completely covered. Do not break the leaves, or they may blow away.
  • Check the heads as they develop. Tied or covered heads may be exposed to increased humidity levels, increasing their susceptibility to Alternaria.
  • Blanching becomes less important in the cooler, shorter days of fall.
  • Note: No need to tie the leaves around the heads of colored cauliflower varieties — they require exposure to light to achieve their rich coloration.
