Brassica oleracea var. botrytis
How to Grow: Culture of cauliflower is similar to broccoli and cabbage. (See Cabbage Cultural Notes.)
Blanching the Curd: When the white head or curd begins to form, tie the top leaves together over it to protect the curd from sunlight that causes the curd to yellow.
Harvest: Harvest while the curd is in the tight bud stage. Don't harvest when heads are wet, or the curds will mold in storage.
Maturity Dates: Days to maturity are from transplant date. Add 25 days if direct seeded.
Seed Savers: Cauliflower will cross with broccoli, brussels sprouts, cabbage, collards, kale, and kohlrabi. Isolate by 1/8 mile for home use. For pure seed of small plantings isolate by 1/4 to 1/2 mile.
Packet: 2 g (average 600 seeds) sows 72' direct-seeded or 360' as transplants.
