September Gardening Tips

  • Trees and shrubs can be planted for fall now through November. Be sure to adequately water new plantings. 
     
  • Perennials, especially spring bloomers like peonies, can be divided now.
     
  • Begin fall seeding or sodding of cool-season grasses. Seedbeds should be raked, dethatched, or core-aerated, followed by fertilizing and seeding. Keep newly planted lawns moist but not wet. 
     
  • Fairy rings and mushrooms may appear in lawns after rain, no control is needed as little to no damage is done to grass. Manually remove mushrooms and treat them as yard waste.
     
  • Clean up any fallen or spoiled fruits. 
     
  • Finish planting cool-season seeds like leafy greens and radishes by mid-September. Sow seeds of these crops in a cold frame or low tunnel to prolong fall harvest.  
     
  • Damage from scorch, sunburn, and heat stress from the summer may be noticeable. In subsequent years, be sure to provide enough water to plants early in the day on hot days.
