Key Tasks for June in Zone 4A
- 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 Direct sow seeds at the recommended depth and spacing. Keep the seedbed consistently moist until germination is complete.
- 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.
