As high temperatures continue in the desert in August, higher humidity may also play a role, and rains may or may not appear. Below are just a few items to check during the month:

  • Remove dead basal foliage of perennials.
  • Trim away dead flowering stems of Autumn sage (Salvia greggii). This stimulates creation of new flowering stems for fall and winter season. Likewise, lightly cut back old, tired stems of blue salvia (Salvia forinacea) to encourage new basal growth.
  • Rebuild basins on plants, especially on slopes, to hold in irrigation water.
  • Check drip irrigation systems to see that they are operating correctly.
  • Hold off on shearing or pruning for another month. Pruning now may expose formerly shaded stems and foliage to sunburn.
  • Make plans for fall planting of annuals and perennials. Order seeds of adapted wildflowers for planting in September and October. Pick a cooler, cloudy day to prepare fall planting beds by digging organic materials into the top 8–10 inches of soil.
