September Gardening Tips

  • Trees and shrubs can be planted for fall now through November. Be sure to adequately water new plantings.
  • Seasonal loss of inner needles on conifers is normal at this time. It may be especially noticeable on pines and arborvitae.
  • Perennials, especially spring bloomers like peonies, can be divided now. When planting peonies plant only 1-2 inches deep, as planting too deep can cause flowers to not form. 
  • Reseed dead spots in the lawn as needed.
  • 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. 
  • Harvest summer herbs now and process them for winter use. 
  • 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. 
  • Whitefly populations are often the highest at the end of summer.
