Fertilizing


  • Fertilize or side-dress your vegetables as needed


Planting


  • Start brussel sprouts and collards for transplanting into the garden in mid-July
  • Plant beans, lima beans, southern peas, pepper, sweet potato, pumpkin, and tomato 

Pruning


  • Prune narrow leaf evergreens like juniper and arborvitae
  • Prune the bigleaf or florist hydrangea when the flowers fade
  • Trim hedges as needed
  • Remove water sprouts or suckers on any fruit trees, crape myrtles, etc.
  • Dead-head faded flowers of phlox, shasta daisy, and daylily to promote a second flowering
  • Trim foliage of your spring flowering bulbs (once they turn yellow/brown and wilt)
  • Prune out dieback on hybrid rhododendron, azalea, mountain laurel, and blueberry
  • Pinch chrysanthemums 1-2 inches every month to encourage branching – last pinch around July 4th

 Spraying


(Use pesticides sparingly and spray only when needed! Always read and follow ALL label directions!)
  • Monitor landscape plants for pests: arborvitae (bagworm), boxwood (leaf miner), crape myrtle (aphids), hemlock (spider mites), and pyracantha (lace bugs).
  • Spray for Japanese beetles as needed
  • Monitor vegetables for pests: cucumber (cucumber beetle), squash (squash borers and aphids), tomato and eggplant (flea beetle), broccoli, cabbage and cauliflower (worms).
  • Keep spraying your tree fruits and bunch grapes with a pest control program.
  • Check your asparagus plants for the asparagus beetle and spray with the recommended insecticide if beetles are observed
  • Continue with rose spray program

 Lawn Care


  • Start zoysia this month or continue fertilizing established zoysia lawn this month
  • Do NOT fertilize tall fescue and bluegrass now

 Propagation


  • Late June is the ideal time to take semi-hardwood cuttings
  • Azaleas, cotoneaster, camellia, holly, pieris, red-tip photinia and rhododendron cuttings should be taken in June or July

 Specific Chores


  • Build a cold frame for rooting your shrub cuttings
  • Renovate your strawberry bed after the berry harvest is completed
  • Water your favorite plants during periods of dry weather
  • Water early in the morning
  • Watering late in the day encourages plant disease growth BUT if you need to water, WATER! Just try not to get the leaves wet!
  • Vegetable gardens need 1 inch of water per week
  • Harvest crops on a regular basis to keep plants producing
