Gardener’s To-Do List for May

Here’s a zone-by-zone to-do list for the month of May.



May To-Do List for Zone 9

  • Plant last runs of lettuce, choosing heat-tolerant varieties that are slow to go to seed.
  • Start new plantings of melons, squash, dried beans, okra, and southern peas that thrive in heat.
  • Set out heat-loving petunias, moss rose (Portulaca grandiflora), amaranth, vinca (Catharanthus roseus), nicotiana, marigolds, and sunflowers.
  • Pull out and compost primula, viola, calendula, and pansy plants that are no longer flowering well.
  • Use drip irrigation to provide a constant supply of moisture to beds; also mulch with organic materials, such as dried grass clippings, pine needles, or leaves.
