  • Keep spraying your tree fruits and bunch grapes with a pest control program.
  • Watch for dark brown spots on your tomato leaves. If observed, spray with a fungicide for early blight.
  • Spray herbicides on the following woody weeds: poison ivy, honeysuckle and kudzu. Use pesticides sparingly. Spray only when needed.

Lawn Care

  • Continue fertilizing zoysia this month. Do NOT fertilize tall fescue and bluegrass now.
  • Start zoysia in June.


  • 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 

  • 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.
  • Vegetable gardens need 1 inch of water per week. Harvest crops on a regular basis to keep plants producing.
