Check out the nursery, online websites and garden books for new plant varieties that use less water.

In a drought year, consider native plants suitable for our area.

Tasks

  • Remove thatch and aerate warm-season lawns (Bermuda, zoysia, St. Augustine) to allow better water penetration.
  • Water citrus, being careful not to overwater.
  • Hand pick snails and slugs daily or use bait. Avoid baits that contain metaldehyde, as they are toxic to all vertebrates.

Pruning

  • Azaleas and camellias as they finish blooming.
  • Finish pruning deciduous trees.

Fertilizing

  • Acid-loving plants (such as azaleas and camellias) after bloom, also annuals.
  • Cool season turf, if fall fertilization was missed.

Planting

  • Plant annual summer herbs and vegetables at two-week intervals for successive crops.
  • Annuals: Begonia (fibrous or wax), sunflower (Helianthus), marigold (Tagetes).
  • Bulbs, corms, tubers: Sternbergia.
  • Fruits and vegetables: onions (green), parsnips, potatoes (white).
  • Trees, shrubs, vines: Toyon (Heteromeles), Rose of Sharon (Hibiscus), citrus, Euonymus.
  • Perennials: alstroemeria, columbine (Aquilegia), false spiraea (Astilbe), deer fern (Blechnum spicant), dianthus.

  • Annuals and perennials: Armeria, snapdragon (antirrhinum), columbine (Aquilegia), fibrous begonia (Semperflorens).

Things to ponder

  • Pull weeds as they begin to emerge to prevent having to spray later.
  • When choosing plants in cell packs from the nursery, be sure roots are not protruding from the bottom of the container.
  • Consider composting to cut down on green waste.
