Key Tasks for March in Zone 8B

  1. 1 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.
  2. 2 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.
