Moana Nursery Teammates say, "For successful high

desert gardening, NOW is the time to ..........."   

Pest Alert:

Root Weevils are having a field day on numerous shrubs & peonies – you’ll know you have them by their tell-tale notching of the leaves.  To control, treat with a combination of Bonide Systemic Granule Insect Control with Bonide Eight.  Make a note to apply Beneficial Nematodes next spring to control the weevils in their larval stage.

Ants have been reported by many as being a huge nuisance inside) and outside – especially on patios & walkways.  Treat with Bonide Ant, Roach, & Spider Killer Spray or Bonide Revenge Ant Killer according to directions.

General Garden & Lawn Care:

  • Heat stressed trees will drop some leaves to conserve moisture.  Additional watering and mulching will help somewhat in this situation.
  • Mulch, mulch, mulch with G&B Organics Soil Building Conditioner, Compost or Planting Mixes.
  • Inspect your irrigation system for leaks, clogged emitters, broken/clogged heads and other problems.  Remember to adjust emitters out from the trunk or base of your plants as they grow.
  • Brown spots in lawn could be a sign of insects, fungus or lack of water from an improperly designed or malfunctioning irrigation system.  Check with one of our plant doctors to determine the cause(s) of your brown spots.  
  • Check all plants weekly to be sure they are getting adequate water; established trees, shrubs, perennials & roses require 1 inch of water per week throughout their root zones.  Water newly planted trees, shrubs and perennials 3-4 times per week. 
  • Water infrequently and deeply – not frequently and lightly.  Early morning is always the best time to water.  Nighttime watering can cause fungus on grass.  Click here for How to Water Wisely for Healthy Plants.
  • Inspect irrigation system regularly for leaks, clogged emitters, broken/clogged head and other problems.  Remember to adjust emitters out from the trunk or base of your plants as they grow.
  • Fertilize lawns with a sustained release fertilizer like G&B Organics Lawn Fertilizer.
  • Control insect pests, including aphids, mealybugs, scale, spider mites, thrips, whitefly and others with lady bugs or use Captain Jack’s Dead Bug Brew, an organic insecticide for chewing insects, and Bonide Insecticidal Soap for sucking insects, or ask us for best controls on significant infestations.
  • Bonide Tomato & Vegetable 3 in 1 may be used as an insecticide, fungicide & miticide up to the day of harvest.
  • Continue to cultivate and weed. 

Tree and Shrub Care:

  • Watch closely for signs of scorch on tender new foliage – the margins of leaves turn brown and crispy – indicating lack of water and/or exposure to hot drying winds.
  • Monitor newly planted trees and shrubs for insects or disease.  Succulent new growth is often the first area to be attacked by insects.
  • Pruning is generally not advised this month, with the exception of shrubs that have just flowered; prune immediately following their flowering.
  • Feed roses for third and final time early in August with G&B Organics Rose and Flower Fertilizer. Do not fertilize after August 15th.
  • Continue to deadhead roses by cutting flowers back to the first set of five leaflets.  
  • Monitor roses closely for mildew.  If detected, spray with Bonide Rose Rx immediately.  Dispose of infected leaves in the trash; do not compost. 
  • Continue checking shrubs and trees for spider mites; hose off affected plants daily and, if necessary, treat with Bonide Rose Rx. Use according to the label.

Perennial & Annual Care:

  • Remove yellowing daylily foliage or leaves that are browned and spotted.  Green leaves must remain on the plant to continue to manufacture food.  Deadhead individual flowers to keep plants looking tidy.
  • Continue deadheading annuals and perennials to encourage more flowering. 
  • Fertilize container plants up to twice per week with G&B Organics High Bloome liquid fertilizer and G&B Organics Bud and Bloom fertilizer every month, but avoid applying in the heat of the day.  Always water plants before adding liquid fertilizer and avoid fertilizing drought-stressed plants.
  • Continue planting new perennials, ornamental grasses & roses.

Herb, Fruit & Vegetable Care:

  • Plant cool season fall crops in succession now. 
  • Remember that deep root watering your apple trees throughout the season will ensure maximum fruit production.  Remove fruit infested with coddling moths from tree and pick up any that has dropped on the ground promptly and discard in trash to reduce coddling moth population. 
  • Keep vegetables picked so the plants will keep producing.
  • Monitor tomatoes and ensure that they receive an even supply of moisture instead of heavy soaking and then a drought. 
  • Keep records of harvest dates to help plan next year’s garden.
  • Monitor vegetables for symptoms of fungus or blight: soft, darkened areas, yellow and dropping leaves, sunken dark spots on otherwise green foliage.
  • Monitor all plants for insects.  Hand-remove large insects such as tomato hornworms, cicadas and other caterpillars.
  • Continue to harvest herbs to use fresh, dry, or freeze in small batches in ice cube tray.  Pinch off developing flowers to retain essential oils and flavor in the plant’s foliage.
  • Continue fertilizing vegetables with G&B Organics Tomato, Vegetable & Herb fertilizer every 2 months and G&B Organics High Bloome liquid fertilizer up to twice per week.


  • Rufous hummingbirds have arrived and will stay until fall, so keep feeders full of fresh sugar water until then.  Be sure to change every few days to avoid spoilage -- more frequently if in full sun all day.  For great family entertainment, consider adding a few extra feeders – one on a window for close up birdwatching and another in a different part of your yard that is a good viewing spot.  Because Rufous are so feisty and territorial, be sure that no feeder is in the sightline of the others.
  • Many birds continue their main molt (replacement of their feathers) which requires extra protein to grow strong feathers for proper flight and effective insulation. For the next few months, offer high-protein bird foods, such as nyjer, peanuts, Jim's Birdacious Bark Butter® and mealworms, to ensure that your birds have a reliable source of protein to help them with molting.
  • Add movement to birdbaths with water wigglers to attract more birds.  A mister is also an attractant – especially for hummingbirds.
  • Continue offering WBU Suet Dough to warblers, nuthatches, wrens & woodpeckers.
  • Continue to supply fresh water and change it every 3 days to keep it clean.  To prevent the chance of disease, clean birdbath weekly with a weak bleach solution (1 part bleach to 9 parts water) and rinse well.
  • Store bird food in a sealed container and keep in a cool dry place to prevent spoilage.
  • To ensure that bird seed is eaten quickly and stays fresh, keep feeders filled with a one or two day supply of seed.  This makes your birdfeeding less wasteful and more economical.
  • Install a customized Wild Birds Unlimited bird feeding station where you can easily watch the birds it attracts.  It can be installed in the ground or on a deck.
