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

General Garden & Lawn Care: ladybug_life_cycle.JPG

  • To control aphids, start with Lady Bugs and a hose. (See life cycle of lady bugs so that you don't inadvertently kill off their eggs, larvae or pupae.) If infestation is great, use Organocide 3 In 1 Garden Spray, Bon Neem II, or Bonide Tomato & Vegetable Spray.  Bonide Rose Rx Systemic Drench can also be used on all ornamentals.
  • Plant warm-season flowering annuals, vines, herbs and vegetables with G&B Organics Starter Fertilizer.  Pinch back 1/3 of new growth to encourage stocky habit (except vines and vegetables).  Wait two weeks before feeding newly planted annuals with anything other than starter fertilizer.
  • Treat broadleaf weeds in lawn and garden now with pre-emergent Bonide Maize Weed Preventer or Weed Beater Complete.
  • Water at optimum time – when winds are calm and temperatures are cool and only when needed -- saturate root zones and let the soil dry.
  • Feed perennials, shrubs & trees if you have not done so this year.
  • Clean ponds and add Pond Perfect or an Eco Sock to keep pond balanced and algae-free.
  • Activate compost pile with garden soil, G&B Organics All Purpose Fertilizer and water.
  • Mow lawn at a height of 3 to 3-1/2 inches, removing no more than one-third of the leaf blade.
  • Fertilize lawn with G&B Organics Lawn Fertilizer. Monitor for weeds and hand pull or spot treat accordingly with Bonide Weed Beater Ultra.
  • Provide water for migrating birds.  Many insect-eating songbirds are attracted to shallow pools & the sound of dripping water.
  • Put your Rescue yellow jacket traps out now.

Tree and Shrub Care:

  • Very important:  remove tree stakes and ties from trees & shrubs planted a year ago or longer.
  • Gently pull off dried flowers of azaleas and rhododendrons, taking care not to break sticky new shoots located at the base of the flowers.  This is a great time to fertilize with G&B Organics Rhododendron, Azalea & Camellia Fertilizer and mulch with G&B Organics Acid Planting Mix.
  • Apply a 3 inch layer of mulch – G&B Organics Soil Building Conditioner or Purely Compost -- around plants to insulate from dryness and temperature swings; be sure to keep compost 3 “ away from trunk/stems of plants.
  • Continue to inspect trees and shrubs for insect and disease problems; treat immediately with appropriate product.
  • Prune spring-flowering shrubs (forsythia, lilacs, quince, almond, viburnum, magnolias, rhododendrons, azaleas) immediately after they bloom.
  • Pinch off long buds’ candles” on mugo pines to maintain compact form.

Perennial & Annual Care:

  • Treat emerging lily shoots and other plants with Plantskydd if rabbits and deer have been a problem.
  • Monitor all annual plantings in containers and window boxes.  On windy days, hanging baskets will require water every day.
  • Continue planting new perennials, ornamental grasses & roses.
  • Stake tall perennials before they reach 6 inches.
  • Continue pinching back fall-blooming perennials – mums, asters & tall sedums; pinch weekly until mid-July to promote stocky growth.
  • Continue to direct perennial vines on their supports.  Encourage climbing roses to develop lateral, flower-bearing canes.
  • Deadhead spring bulbs once they’ve finished flowering but allow foliage to wither completely before removing.
  • Stake peonies to support blooms when they reach 10” in height.
  • Plant summer bulbs with G&B Organics Bud and Bloom Booster – Moana Nursery has a large selection of gladiola, dahlias and lilies.
  • If earwigs have shown themselves, get ahead of them with Bonide Bug & Slug Killer

Indoor Plant Care:

  • Begin to harden off warm-season transplants, moving them into a cold frame or protected area.
  • Gradually move houseplants outside to protected areas.  Place large houseplants potted in plastic into larger, heavier pots to keep them from falling over in wind.  Do not expose to afternoon sun.  Carefully monitor for insects.
  • Prune and fertilize overwintered tender plants like hibiscus, gardenia & geranium with G&B Organics High Bloome Fertilizer or Grow More Sea Grow; take outside once night temps reach 40 degrees.

Herb, Fruit & Vegetable Care:

  • Place codling moth traps in apple trees now – 1 per tree in an easily accessible location.  When trap reveals several moths, spray tree with Captain Jack’s Dead Bug Brew. Since codling moths produce up to 4 generations (one every 6 weeks), it’s important to install a new trap and repeat spraying every 6 weeks for continued fruit protection.
  • Plant corn, tomatoes, snap beans, summer squash and herbs with G&B Organics Starter Fertilizer.
  • Spread several inches of G&B Organics Soil Building Conditioner or Harvest Supreme on vegetable and herb beds and mix in well, if not yet done.

Bird Tips:

  • Clean all bird feeders with hot soapy water and a bleach solution of 1-part bleach to 10 parts water.  Rinse and thoroughly dry before refilling.  Feeders should be cleaned and bleached every 2-3 months to prevent disease from spreading and to keep feeders in good condition.  .
  • Install a birdhouse; many birds are now building their nests.
  • Hummingbirds & orioles have shown up in various parts of town.  Put out oranges, grape jelly for orioles and WBU Hummingbird and Oriole Nectar for both hummingbirds and orioles.   Be sure to change the nectar every few days so it doesn’t spoil.
  • Continue to supply fresh water and change it every 3-5 days to keep it clean.  To prevent the chance of disease, clean birdbath weekly with a weak bleach solution and rinse well.
  • 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.
  • Offer WBU Bark Butter Bits, Peanut Butter n’ Jelly Suet Dough or Jim’s Birdacious Bark Butter to provide the extra calcium needed during nesting season.
