Cauliflower Seed Planting Information:

Cauliflower will not grow well where temperatures average above 75 F or where winter temperatures drop below 25 F. Poor cauliflower is usually a result of improper planting time, low moisture or low fertility. Plant your seeds indoors, 5 to 7 weeks before setting outside. Spring planting should occur as soon as soil can be worked, and fall planting done around July or August. Plants can grow 12" tall.

Soil Requirements:

Requires fertile soil with compost and some lime. Apply much and grass clippings, or straw around base of plant.

Water Requirements:

Water regularly to keep soil cool and moist. Keep watered during dry and hot spells.

Fertilizer Requirements:

Use RootBlast, Vegetable Alive, and Slow Release Fertilizer when transplanting outdoors. Periodically apply Miracle Gro.

Harvest Tips:

Cut heads below the inner leaves when the heads or about 8" in diameter.
