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.
