Garden Checklist for the week of April 9, 2021

There is much beauty in the late spring gardens of the central San Joaquin Valley.


  • Sometimes gardeners need to accept a small amount of pest damage to plants.
  • Instead of trying to kill insects, learn which ones are beneficial and protect them by avoiding use of synthetic insecticides.
  • Water and mow lawn. Set mower blades higher to shade out weeds and keep roots cool.


  • Pinch new growth on flowers and shrubs to encourage a compact shape.
  • Prune azaleas, lilac, camellias, deciduous magnolia, dogwood, Indian hawthorn, spirea, forsythia and flowering quince as they finish blooming.


  • Fertilize, fall planted shrubs and ground cover, remembering that a little used more often is better than a lot at one time.
  • Do not over fertilize. Excessive fertilization leads to contamination of waterways and excessive plant growth that requires more water.


  • Plant annuals and perennials for spots of seasonal color.
  • Perennials: yarrow (Achillea), dianthus, plant from seed.
  • Bulbs, corms, tubers:  gladiolus.
  • Fruits and vegetables: beans, snap beans, potatoes, corn.
  • Tree, shrubs, vines: Toyon (Heteromeles).
  • Annuals: floss flower (Ageratum), Artemisia, strawflower (Helichrysum).

Consult the California Garden Web for more information.
