What you need to know to Plant & Grow
Kong Sunflower is straightforward 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, shelter-protected location with rich, 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 massive stalks room to develop properly.
-
Indoor Sowing: For a head start on height, start seeds indoors 2 to 3 weeks before the last expected frost using plantable peat pots or Jiffy 7s to prevent root disturbance. Maintain a temperature of 21°C throughout the 5 to 10 day germination period. Harden off seedlings before transplanting out into full sun.
-
Garden Care & Nutrition: Keep soil evenly watered during dry periods to support rapid vertical growth. Feed twice during the season with a granular 15-5-15 fertilizer (or equivalent balanced formula) to build strong, wind-resistant stalks.
