What you need to know to Plant & Grow
Suntastic F1 is simple to cultivate, whether direct-sown into warm spring soil or started early in plantable pots.
-
Outdoor Direct Sowing (Recommended): Direct sow seeds outdoors in late May once soil has warmed thoroughly. Select a full-sun 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 plants ample room to branch and flower.
-
Indoor Sowing: For an earlier display, start seeds indoors 2 to 3 weeks before your last expected spring frost using plantable peat pots or Jiffy 7s to prevent root shock during transplanting. Maintain a temperature of 21°C for the 5 to 10 day germination period. Harden off seedlings carefully before transplanting into full sun outdoors or into patio containers.
-
Garden & Container Care: Keep soil evenly moist throughout the season. Fertilize twice during the growing season with a granular or water-soluble 15-5-15 fertilizer (or equivalent balanced formula) to support its three successive waves of heavy flowering.
