What you need to know to Plant & Grow
Lemon Queen Sunflower is simple to establish by direct sowing in late spring or starting early in peat pots.
-
Outdoor Direct Sowing (Recommended): Direct sow seeds outdoors in late May once soil has warmed thoroughly. Choose a sunny site with well-draining soil. Sow seeds 6 to 12 mm deep and 7.5 to 10 cm apart. Thin or transplant seedlings to 30 to 45 cm apart to give the branching stems plenty of room to spread.
-
Indoor Sowing: For earlier blooms, start seeds indoors 2 to 3 weeks before your last expected frost using plantable peat pots or Jiffy 7s to minimize root disturbance. Maintain a temperature of 21°C for the 5 to 10 day germination period. Harden off seedlings carefully before transplanting outside to a full-sun location.
-
Garden Care & Nutrition: Keep soil evenly moist throughout the season. Fertilize twice during the growing season with a granular 15-5-15 fertilizer (or equivalent balanced formula) to support strong, wind-resistant branching and continuous flower production.
