Harvest in September

Nothing to harvest in September for Zone 11A.
Next window: November — 8 varieties, including Black Oil Sunflower Microgreens, Chervil, Dukat Dill.

Key Tasks for September in Zone 11A

  1. 1 Start 225 varieties indoors this month under grow lights or in a sunny south-facing window. Use a seed-starting mix and bottom heat (70–75°F) for best germination rates.
  2. 2 Harden off transplants before moving outdoors — set them outside in a sheltered spot for increasing hours over 7–10 days before planting in the ground.
  3. 3 Apply 2–3 inches of mulch around heat-sensitive crops to retain moisture and keep root zones cooler. Water deeply and less frequently rather than shallow daily watering.
  4. 4 Begin fall cool-season planting window this month. Direct sow lettuce, spinach, arugula, and radishes now for harvest before hard frost.
  5. 5 Check soil moisture before watering — stick a finger 2 inches into the soil. Water only when the soil is dry at that depth. Consistent moisture is more important than frequency.
