How to Grow Organic Snowball Cauliflower Seeds (Y Improved Self-Balancing):
Snowball Cauliflower is a cool-season brassica that forms smooth white heads, and the “Y Improved Self-Balancing” type is bred for reliable head development. Start seeds indoors 4–6 weeks before your last frost for spring crops, or sow in late summer for a fall crop (best flavor comes from cool finishing weather). Use seed-starting mix, sow 0.5 cm (¼ in) deep, keep evenly moist, and germination usually takes 5–10 days in cool-to-mild temps. Give strong light once sprouted. Transplant seedlings outdoors when they have 3–4 true leaves and weather is mild, spacing 45–60 cm (18–24 in) apart in rows 60–75 cm (24–30 in) apart. Plant in full sun (light shade in hot areas) and rich, well-drained soil with plenty of compost. Keep soil cool and moist; cauliflower hates heat stress and drought swings.
How to Care for Organic Snowball Cauliflower:
Water consistently—aim for steady moisture, not soggy soil—because uneven watering causes small or ricey heads. Mulch helps keep roots cool and reduces stress. Cauliflower is a heavier feeder than many veggies, so side-dress with compost or a balanced vegetable fertilizer every 2–3 weeks until heads begin forming; avoid excess nitrogen late, which delays heading. When the head reaches about egg to tennis-ball size, “self-blanching” varieties often wrap leaves naturally, but if the curd is exposed to sun, tie a few outer leaves loosely over the head to keep it bright white. Watch for common brassica pests like cabbage worms, aphids, and flea beetles—use insect netting early, hand-pick caterpillars, or treat with gentle soap/neem as needed. Harvest when heads are firm, tight, and about 15–20 cm (6–8 in) across (or your desired size), cutting with a short stem and a few wrapper leaves. Don’t wait too long—overmature heads loosen and yellow.
