Garden Checklist for the week of July 23, 2021

  Forget the guilt about what’s going on outside. It’s not your fault that it’s hot!


   Check sprinklers and adjust timers weekly if necessary.
   Pre-irrigate to soften the ground for tilling in preparation for fall gardens.

   When the lawn needs mowing, mow cool-season grasses, such as tall fescue, to 3 inches and bermudagrass to 1 inch. Mowing shorter than these levels will encourage weeds and a shallow, less drought tolerant root structure.

   Prune apricot, oleander and olive trees during dry weather to reduce future disease problems.



  Cut back on fertilizer when water is limited and landscape plants remain in drought survival mode.

   Avoid planting annuals and perennials unless it is absolutely necessary.
   Bulbs, corms, tubers: autumn crocus.

     Fruits and vegetables: eggplant, fig, garlic, grapes, onion.

Things to ponder

   Keep water away from trunks of trees and crowns of plants.
     Drought tip:  Preserve the largest climate appropriate plants in the landscape. Mature trees and large shrubs may take many years or even decades to replace, while groundcovers, lawns, flower beds and vegetable gardens can be re-established in a season or two.

Seasonal IPM Information

Foliage feed caterpillars

Most flowers are susceptible to damage from caterpillars of one or more species. Caterpillars are the immature or larval stage of moths and butterflies. Only the larval stage chews plants. Although adults consume only liquids, such as nectar and water, they are important because they choose which plants to lay eggs on. Larvae have three pairs of legs on the thorax (the area immediately behind the head) and leglike appendages on some, but not all, segments of the abdomen.

Identification of species
