Garden Calendar






It’s time to get your garden ready for the burst of spring growth.

Plant color annuals such as pansies, petunias, larkspur, and primrose. Plant warm-season flowering bulbs such as canna, dahlia, daylily, and gladiolus. Set out warm-season annuals such as cosmos, four o’clock, globe amaranth, gloriosa daisy, lisianthus, marigold, portulaca, vinca, zinnia, celosia, salvia, sunflower, gaillardia, beans, okra, cucumber, peanut, pumpkin, melon, and squash. Plant seedlings of pepper, tomatoes, squash, eggplant and green onion. Sow seeds for warm-season flowers such as hollyhock, salvia, sunflowers, tithonia and zinnia in garden beds.

Look for new growth on native and desert-adapted plants. Prune winter-damaged plant parts. Allow flower stalks on spring bulbs to brown and die back naturally. When spent, clip off at the base.

Watch for the iron deficiency on citrus, pyracantha, gardenia, nandina, and bottlebrush. Look for yellow leaves with green veins, which signal gardeners to apply chelated iron according to package directions. Always water before and after applying any fertilizer. Feed Bermuda grass with a high-nitrogen fertilizer. Feed roses every two weeks or use a slow-release fertilizer for longer season intervals during spring’s peak bloom.  

Reap flower seeds. Allow wildflowers and cool-season annual flowers to dry and scatter seed, or collect dry seed and store to sow next fall.

Adjust drip-irrigation systems to accommodate new plants and the warming temperatures

Plant red bird of paradise, ageratum, eupatorium, passion vine, desert hackberry and datura to attract butterflies.
Plant container-grown roses.
Plant new citrus and protect trunks from sunburn. Don’t fertilize when
Plant desert landscape shrubs, cacti and succulents so that the roots re-establish before the summer heat.
