Gardening Tips for May for Owensboro, KY

Midwest Region

  • Mow your lawn when the grass is dry. To keep a healthy lawn, never cut more than one-third off the total grass height.
  • Start cucumber, cantaloupe, summer squash, and watermelon seeds indoors.
  • Sow more cool-season vegetables outside: beets, carrots, lettuce, chard, and radishes.
  • Sow green beans, sweet corn, pumpkin, and melons.
  • Start hardening-off tomatoes.
  • Plant sweet potato slips.
  • Harvest rhubarb. Pull off leaf stalks instead of cutting them.
  • Protect beets from leaf miners by placing row covers over them.
  • Finish pruning spring-flowering shrubs that are done blooming.
  • Finish cutting back the dead branches on perennial flowers and other shrubs.

  • Apply fertilizer to give the vegetable garden a good start.
  • Control weeds before they seed!
  • Begin planting warm-season annuals and summer bulbs, such as dahlias and cannas.
