May Checklist

Gardening is really getting started this month. Here’s a list for your monthly job jar.

  • Mow the lawn at a height of 2 1/2 to 3 inches while never removing more than 1/3 of the leaf blade. Leave the clippings on the ground.
  • Remove flowers from newly established strawberry plantings. Let them become established this year and form fruit next year.
  • Remove seed stalks from rhubarb as soon as you see them.
  • Harvest rhubarb through early June.
  • Harvest mature asparagus beds for 6 to 8 weeks only.
  • Lift and divide old chrysanthemum plants or set out new plants purchased or grown from cuttings. Pinch back mums when they are about six inches tall for bushier plants.
  • Continue to pinch back the mums until mid-July.
  • Plant gladiolus corms every two weeks for continuous bloom.
  • Remove daffodil and tulip flowers as they fade. Leave the foliage in place until it turns brown and dies. Dig bulbs for storage after the leaves die.
  • Plant dahlia and canna tubers mid- to late May.
  • Prune spring-flowering shrubs after the flowers fade.
  • Have a magnificent May!
