Succession Planting, Summer - Fall

  • Early Spring (Indoor Sowing):

    • Planting: Start seeds indoors in late February to early March. Sow seeds in soil blocks and keep them under grow lights. Germination typically takes 10-14 days.

    • Harvesting: Begin harvesting when flowers are fully open, about 60-70 days after sowing. This will generally be in late May to early June.

  • Mid to Late Spring (Greenhouse Transplanting):

    • Planting: Transplant seedlings from indoors to an unheated greenhouse in late April to early May. Space seedlings 8-12 inches apart.

    • Harvesting: Harvest starts around late July to early August, 60-70 days after transplanting.

  • Late Spring (Direct Sowing Outdoors):

    • Planting: Direct sow seeds outdoors in late May after the last frost. Plant seeds ¼ inch deep and space them 12-18 inches apart. Germination takes 10-14 days.

    • Harvesting: Expect to harvest flowers in mid to late August, 60-70 days after sowing.

  • Mid Summer (Additional Outdoor Sowing):

    • Planting: Sow a second batch of seeds directly outdoors in mid to late July. Follow the same depth and spacing as earlier sowings.

    • Harvesting: These flowers will be ready to harvest in early to mid-fall, approximately 60-70 days after sowing.
