Plan a rewarding cool-season harvest with cauliflower seeds from David's Garden Seeds®. Cauliflower grows best in cool or mild conditions and brings a tender texture and versatile flavor to roasted vegetables, steamed sides and hearty soups. Compare the varieties below for maturity and growing requirements that fit your garden.

Match Your Planting to the Season

In our zone 9b growing area, cauliflower can be grown during late fall and winter. Your ideal planting dates will depend on local weather and the variety you choose. Plan for heads to develop in mild conditions rather than prolonged heat, and follow the seed packet's sowing and transplanting guidance.

Start with healthy transplants: Give seedlings adequate light and gradually harden off indoor-grown plants before transplanting. Avoid keeping seedlings in cramped containers for too long.
Prepare a fertile bed: Choose a sunny location with well-drained soil and follow the variety's spacing recommendations.
Keep growth steady: Water consistently and use mulch to conserve moisture. Drought, temperature stress and interrupted growth can affect head development.
Watch for pests: Check leaf undersides and growing centers for caterpillars and aphids, addressing problems before they damage developing plants.

Protect and Harvest Developing Heads

Some white cauliflower varieties benefit from having their leaves loosely gathered over the developing head to protect it from sunlight, while self-blanching types need less assistance. Follow the variety's directions and avoid trapping excessive moisture. Harvest while heads are compact and firm, before the curds begin to separate, and refrigerate promptly.

From Garden to Kitchen

Enjoy cauliflower roasted in florets, steamed until just tender or simmered in soups. Its mild flavor works well with herbs, spices and savory sauces. Use each variety's listing for specific head color and size rather than assuming every cauliflower grows or harvests alike.
