Detailed Planting Instructions

Follow these steps for bumper crops:

  1. Timing: Start seeds indoors 8-12 weeks before your last spring frost (e.g., February-March in zones 5-7).
  2. Soil Prep: Choose well-drained, fertile soil with pH 6.0-7.0. Amend with compost; full sun (6-8+ hours/day).
  3. Sowing: Sow seeds ¼-½" deep in trays/cells. Keep at 70-75°F; thin to strongest seedlings. Harden off transplants.
  4. Transplanting: Plant pencil-thick seedlings 4-6" apart in rows 12-18" apart after frost risk (soil 45°F+). Firm soil around roots.
  5. Care: Water consistently (1"/week); mulch to retain moisture. Fertilize lightly with balanced organic (e.g., 5-10-10) every 4 weeks. Weed diligently.
  6. Harvest: 105-115 days; pull when 50-75% tops yellow/fall over. Cure in shade 1-2 weeks, then store cool/dry.
