Succession Planting: Essential for single-stem crops like ProCut Sunflowers to ensure you have fresh flowers every Sunday.
Cut-and-Come-Again: Crops like Zinnias, Cosmos, Basil, and Gomphrena produce more stems the more you harvest.
Phase 1: The "One-and-Done" Schedule (Sunflowers & Stock)
Sunflowers (ProCut & Starburst): To have blooms every Sunday, you must plant these in batches (successions).
Batch 1 (Plant Mar 1): Ready ~April 20 (Sunday Market).
Batch 2 (Plant Mar 15): Ready ~May 4.
Batch 3 (Plant Mar 29): Ready ~May 18.
Continue planting every 10–14 days through August.
Stock (Iron Purple): Plant all on March 1. They need cool weather to set buds. If planted later, the Texas heat (May/June) will prevent flowering. Harvest likely mid-to-late May.
Phase 2: The "Cut-and-Come-Again" Schedule (Volume Producers)
Plant on March 1 (Hardy Annuals):
Nigella, Orlaya, Cerinthe, Calendula, Godetia: These tolerate cooler March nights. They will bloom late April through May. Note: As Texas heats up in June, these will fade.
Plant on March 15 (After Frost Risk - Tender Annuals):
Zinnias, Cosmos, Celosia, Gomphrena, Basil, Amaranth, Marigolds:
Harvest Start: Late May to Early June.
Maintenance: Pinch the central stem when plants are 8-12" tall (approx. mid-April) to encourage branching. This sacrifices the first bloom but doubles/triples the flower count for June/July markets.
Long Season Set (March 1):
Eucalyptus, Yarrow, Statice, Salvia (Victoria & Oxford), Aster: Plant immediately. These take 3-4 months to mature. Expect harvest starting late June or July.
