Gardening Tips for September for Thayne, WY

Midwest Region

  • Prune those trees that are susceptible to disease if pruned in the spring, such as maple, birch, oak, and mountain ash.
  • This is a great time to plant new trees and shrubs because the new roots will have plenty of time to become established before the spring.
  • Fall is the best time to start lawn grasses from seed. Till the soil before sowing and provide several light waterings each week.
  • Dig the herbs from your garden and plant them in pots to bring indoors for the winter; such herbs include rosemary, parsley, chives, and thyme.
  • Begin moving houseplants inside.
  • Perennials can be divided and replanted.
  • Watch for frost forecasts. Harvest tomatoes before the first killing frost. Ripen indoors away from sunlight.
  • Harvest Brussels sprouts and parsnips once they've been exposed to frost.
  • If you want to prolong your fall crops, sow radish, lettuce, spinach, and other greens in cold frames.
  • Be sure to bury or throw away any fallen fruit to help keep away any unwanted pests from your yard.
  • Compost garden debris and kitchen scraps.
  • Take root cuttings from annuals, such as begonias, geraniums, and impatiens; plant them in a container and keep them in a sunny place indoors.
  • Save the seeds from your favorite self-pollinating flowers. Dry the seeds and store them in sealed containers for the winter.
  • Improve your garden soil by adding manure, compost, and leaves to provide it with more organic matter.
  • Aerate your lawn if the soil is compacted. Have your soil tested to see if you need lawn fertilizer.
