September 16th thru September 30th, 2018

Moana Nursery Teammates say, "For successful high desert gardening, NOW is the time to ..........."

Apply pre-emergent now to control cheat grass next spring; cheat grass has been a major contributor to wildfires this year.  We recommend Bonide Crabgrass & Weed Preventer for small areas, Weed Impede for large areas, Amaze for medium areas and Concern & Bonide Maize made of corn gluten for pet friendly areas. 

General Garden & Lawn Care:

  • Get started on your landscape design for a fall installation – the best time to plant.
  • Reinvigorate your lawn with fertilizer and, if needed, top dressing and overseeding.
  • Fertilize lawn with G&B Organics Lawn Fertilizer or Bonide Winterizer, if you haven’t done so yet.
  • Install a new lawn or repair bare spots with Bonide Dura-Turf Premium Grass Seed and Lawn Seed Starter Fertilizer, then cover with G&B Organics SBC.
  • Core aerate lawn if you didn’t do so in spring or if you have heavy clay soils or areas of compaction.
  • Start a compost pile.
  • Plant trees, shrubs and perennials – fall is the best time to plant.
  • Spraying or pulling weeds before they go to seed will reduce weeds next spring

Tree and Shrub Care:

  • Continue to deadhead roses by cutting flowers back to the first set of five leaflets.
  • Apply one year Bonide Annual Tree & Shrub Insect Control to trees and shrubs to prevent early spring infestations of aphids and other troublesome insects.
  • Treat chlorotic (washed out green/yellowish color) trees and shrubs with Encap Iron.  Perform a pH test or full soil analysis in chronic problem soils.
  • Do not fertilize trees and shrubs with fast-acting fertilizer between September 1 and March 15th.  Consider mulching with G&B Organics Compost or fertilizing with G&B Organics All Purpose Fertilizer or Paradise slow release fertilizer if your landscape is nutrient deficient.
  • From August thru fall, it is natural for evergreens to drop their needles on the inside of the branches, closest to the trunk.  However, if needles on the outer ends of branches begin to turn yellow, brown or drop, there is likely a problem that should be treated immediately.  To determine the exact cause and treatment plan, visit one of our plant doctors.

Perennial & Annual Care:

  • Refresh flower beds and containers with cool-season favorites such as pansies, ornamental cabbage & kale, chrysanthemums or fall-blooming asters.
  • Purchase spring blooming bulbs now for best selection, but don’t plant any until later in October and November.
  • Allow certain dried flowerheads to remain standing for fall and winter interest and food source for birds; these include astilbe, coneflower and globe thistle.
  • Divide daylilies, peonies & iris.
  • Continue deadheading annuals and perennials to encourage more flowering.
  • Gather your canning supplies and food dehydrator and start researching pickling recipes to prepare for your harvest. 

Herb, Fruit & Vegetable Care:

  • Plant cool-season vegetables – lettuce, spinach, onions, garlic and endive at two week intervals to keep a supply coming into cooler weather.  If they bolt, remove seed heads.
  • Continue to harvest warm-season vegetables as they ripen.  Warm-season crops like peppers and tomatoes must be picked as soon as possible.  If an early frost threatens, cover these plants with Dalen Harvest Guard
  • Begin to harvest late-season squash and early pumpkins. 
  • Allow collards, kale and Brussels sprouts to be hit with frost before harvesting to improve their flavor.
  • 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.


  • Put out quail blocks to feed those large recently hatched families of quail and other ground feeding birds.
  • Rufous hummingbirds will stay until October, if not longer, so continue to keep feeders full of nectar until then.  (Hummingbird nectar:  4 parts water to 1 part granulated sugar – do not use honey, organic sugar or red dye.)  Be sure to change every few days to avoid spoilage.  Consider adding Nectar Defender to extend life of nectar in feeders.
  • Many birds continue their main molt (replacement of their feathers) which requires extra protein to grow strong feathers for proper flight and effective insulation.  Continue to offer high-protein bird foods, such as nyjer, peanuts, black oil sunflower, sunflower chips, Jim's Birdacious Bark Butter® and mealworms, to ensure they have a reliable source of protein to help them with molting.
  • Put out suet or no-melt suet dough (if feeder is in the sun) and mealworms to attract insect-eating birds which are beginning their migration south.
  • Add movement to birdbaths with water wigglers to attract more birds.
  • Continue to supply fresh water.  To prevent the chance of disease, change the water daily during the hot weather and 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.
  • 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.
