Ornamentals

  • Week 1: Deadhead bulbs and spring flowering perennials as blossoms fade.
  • Week 1: Early detection is essential for good control of vegetable pests. Learn to identify and distinguish between pests and beneficial predators.
  • Week 1: Watch for bagworms feeding on many garden plants, but especially juniper and arborvitae.
  • Week 1: Thin seedlings to proper spacings before plants crowd each other.
  • Weeks 2-4: Plant tropical water lilies when water temperatures rise above 70 degrees.
  • Weeks 2-3: When night temperatures stay above 50 degrees, bring houseplants outdoors for the summer.
  • Weeks 2-3: Apply a balanced rose fertilizer after the first show of blooms is past.
  • Weeks 2-3: Rhizomatous begonias are not just for shade. Many varieties, especially those with bronze foliage do well in full sun if given plenty of water and a well-drained site.

Lawns

  • Weeks 1-4: Water turf as needed to prevent drought stress.
  • Weeks 1-4: Mow lawns frequently enough to remove no more than one-third the total height per mowing. There is no need to remove clippings unless excessive.
  • Weeks 1-4: Gradually increase the mowing height of zoysia lawns throughout the summer. By September, the mowing height should be 2 to 2.5 inches.

Vegetables

  • Weeks 1-2: Plant pumpkins now to have Jack-o-lanterns for Halloween.
  • Weeks 1-2: As soon as cucumber and squash vines start to 'run,' begin spray treatments to control cucumber beetles and squash vine borers.
  • Weeks 2-4: Set out transplants of Brussels sprouts started last month. These will mature for a fall harvest.
  • Weeks 2-4: To minimize diseases, water with overhead irrigation early enough in the day to allow the foliage to dry before nightfall.
  • Weeks 2-3: Start seedlings of broccoli, cabbage and cauliflower. These will provide transplants for the fall garden.
  • Weeks 3-4: Control corn earworms. Apply several drops of mineral oil every 3 to 7 days once silks appear. Sprays of B.T. are also effective.

Fruits

  • Week 1: Oriental fruit moths emerge. Most serious on peaches where first generation attacks growing tips. Shoots will wilt. These should be pruned out.
  • Week 1: Thinning overloaded fruit trees will result in larger and healthier fruits at harvest time. Thinned fruits should be a hands-width apart.
  • Week 1: Enjoy the strawberry harvest.
  • Week 2-3: Renovate strawberries after harvest. Mow the rows; thin out excess plants; remove weeds; fertilize and apply a mulch for weed control.

Miscellaneous

  • Weeks 3-4: When using any gas powered equipment, be sure to allow the engine a few minutes to cool before refilling empty fuel tanks.
  • Weeks 3-4: A mailbox mounted on a nearby post makes a handy place to store and keep dry any small tools, seeds, labels, etc. frequently used in the garden.
