Key Tasks for March in Zone 8A

  1. 1 Start 34 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 Direct sow seeds at the recommended depth and spacing. Keep the seedbed consistently moist until germination is complete.
  4. 4 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.
