What you need to know to Plant & Grow
The Joker Sunflower is easy to cultivate, whether direct-sown into warm spring soil or started early indoors.
-
Outdoor Direct Sowing (Recommended): Direct sow seeds outdoors in late May once soil has warmed thoroughly. Select a full-sun location with well-draining soil. Sow seeds 6 to 12 mm (1/4 to 1/2″) deep and 7.5 to 10 cm (3 to 4″) apart. Thin or transplant seedlings to 30 to 45 cm (12 to 18″) apart to ensure sturdy stem development.
-
Indoor Sowing: For an earlier start, sow seeds indoors 2 to 3 weeks before your last expected spring frost using plantable peat pots or Jiffy 7s to prevent root disturbance during transplanting. Maintain a temperature of 21°C (70°F) for the 5 to 10 day germination period. Harden off seedlings carefully before transplanting out to a full-sun site.
-
Garden Care & Nutrition: Keep soil evenly moist throughout the growing season. Feed plants twice during the season with a granular 15-5-15 fertilizer (or equivalent balanced formula) to support tall growth and heavy double-flower production.
