Starting Indoors Sunflowers possess a highly sensitive taproot. Better to direct sow, but you can start indoors in biodegradable peat pots 3-4 weeks before your last frost. 2. Germination Maintain consistent moisture and a warm temperature of 70-80°F. Seeds usually germinate rapidly in 7-10 days. 3. Hardening Off Gradually introduce seedlings to outdoor conditions over 7 days after the danger of frost has entirely passed. 4. Transplanting Direct sow or plant outdoors in full sun, spacing them 24-36 inches apart to allow room for enormous growth. Bury the seedling correctly to avoid root disturbance. 5. Care Water deeply at the base. Though incredibly sturdy, their towering height may require support or staking in areas prone to very high winds.
