Key Tasks for August in Zone 5B

  1. 1 Direct sow seeds at the recommended depth and spacing. Keep the seedbed consistently moist until germination is complete.
  2. 2 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.
  3. 3 Begin fall cool-season planting window this month. Direct sow lettuce, spinach, arugula, and radishes now for harvest before hard frost.
  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.
