August Gardening Tips

  • Panicle hydrangeas may flop over with the weight of flower heads. This is normal and removal is optional. 
     
  • Deadhead annuals and perennials. Fertilize some annuals for the last time to encourage a new flush of blooms for the fall. 
     
  • Iris borer moths emerge from the soil to lay eggs on iris leaves in late August. 
     
  • Brown patch of cool-season lawns and summer patch may be present. 
     
  • High heat (90oF+) can cause pollination issues in cucurbits, tomatoes, peppers, and eggplants. 
     
  • Squash vine borer damage may be prominent now; plants suddenly wilt and sawdust-like debris can be found near the base of the plant.  
     
  • Be sure to give plants adequate water, especially during times of high heat. This will help defend the plants against drought and heat stress.
