Fall in central Oklahoma can be a bit turbulent for our plants. That’s why it’s good to keep on schedule with regular maintenance. Oklahoma Cooperative Extension Service has many resources to assist you in developing and maintaining the landscape you desire. I hope that you find these timely tips helpful.

Bermudagrass Lawn

  • Once turf goes dormant you may begin controlling broadleaf weeds with a post-emergence herbicide.
  • If you have an irrigation system, continue watering a half an inch a week. 

Cool Season Lawn

  • Mow turf at a height of two and a half inches.
  • Fertilize with a complete fertilizer at a rate of one to one and a half pounds of nitrogen per 1,000 square feet. For example, if you are using a 15-5-10, you would need to apply 6.7-10 pounds of material per 1,000 square feet.
  • Irrigate with 1 inch of water per week.
  • Control broadleaf weeds with post-emergence herbicide.

Trees & Ornamentals

  • Plant spring flowering bulbs, pansies, and “cole” crops.
  • Scale insects can be controlled on deciduous trees with dormant oil: spray when the temperature is above 40 degrees.
  • Plant ball and burlap and containerized trees.
  • Prune trees for safety purposes only. The best time is after November 15 if the tree has gone dormant.
  • Wrap trunks of young trees to prevent sun and wind scald.
  • Control pecan predators.

Everything Else

  • If you haven’t picked up the twigs from your yard, do that now and burn or otherwise dispose of them. Twig girdlers lay their eggs in the end of the twig and overwinter.
  • Incorporate fallen leaves into garden spots for added organic material.
  • Discard any diseased plant material from the garden and landscape to ensure it does not get added to a compost pile.
  • Drain fluids from mowers before storage.
  • Cover faucets.
  • Drain and hang hoses.
  • Clean and oil garden tools.
