Key Tasks for March in Zone 7B

  1. 1 Start 92 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 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.
