Cauliflower | Early Snowball

Grow classic, dense, and snow-white heads of Early Snowball Cauliflower in your home garden. This exceptional heirloom variety is a gardener’s favorite, prized for its self-blanching habit where heavy inner leaves naturally wrap over the head to protect its crisp texture, sweet, mild flavor, and bright white appearance.

These vigorous plants produce heavy yields of uniform 6- to 8-inch curds throughout the cool growing season, making them a productive and rewarding addition to any brassica patch. Start seeds indoors in early spring or midsummer for Canada's cool shoulder seasons, as cauliflower thrives in moderate, cool temperatures for optimal head development.

How to Grow 'Early Snowball' Cauliflower from Seed

Start cauliflower seeds indoors 4–6 weeks before your last spring frost date for a spring crop, or in midsummer for a fall harvest. Sow seeds approximately 6 mm (1/4 inch) deep in trays filled with a sterile, well-draining seed-starting mix.

Keep the soil moist and maintain temperatures around 18–21°C (65–70°F) for rapid germination. Provide bright, continuous light once seedlings emerge to maintain sturdy stem development.

Harden off seedlings over 7–10 days before transplanting outdoors. Space plants approximately 45–60 cm (18–24 inches) apart in rows spaced 60–75 cm (24–30 inches) apart in rich, compost-amended soil.

Water consistently and deeply, ensuring soil stays evenly moist throughout head development. Harvest when curds are firm, compact, and reach 15–20 cm (6–8 inches) in diameter before the curd sections begin to separate.
