CBMGA September Gardening Tips

North East Texas Hardiness Zone Map
Use browser back arrow to return to this page

Planting

• Divide and re-plant spring blooming perennials such as Iris, yarrow, daisies, daffodils and daylilies (late September to
early October).
• Plant chrysanthemums, asters, petunias, marigolds and other fall color plants.
• Sow wildflower seeds and press into soil surface to improve germination.
• Plant cool season fescue grass (Sept. 1 to Oct. 15), or overseed established fescue lawns, if needed. If desired,
overseed Bermuda with winter rye, before mid October.
• Plant beets, broccoli, cabbage, carrots, cauliflower, cilantro, collards, bush English and snap peas, leaf lettuce, bush
lima beans, onion seeds, parsley, radishes, spinach, and turnips for fall harvest. If you don’t plant a fall vegetable garden,
sew Elbon rye as a winter cover crop.
• Now is the time to start looking for that new tree you would like to plant this fall.

Fertilizing and Pruning

• Avoid pruning spring-flowering trees and shrubs during the fall, as pruning now will reduce spring flowers.
• Continue to cut back spent flowers of annuals and perennials to encourage fall blooming until first frost.
• Trim dead or damaged wood from trees and shrubs but avoid drastic pruning.

Garden Watch

• Fertilize warm season turf grasses for the last time this year if soil test advises to do so.
• Apply a pre-emergent herbicide for cool season grassy weed control. It is also time to apply a pre-emergent for
broadleaf winter weeds. Apply both by the end of the month, but do not try to mix products. Then water normally. Do not use
a pre-emergent if you plan to overseed your lawn. Watch for brown patch in St. Augustine lawns and control with labeled
fungicide.
• Control black spot and powdery mildew on roses with labeled fungicide.
• Treat peach trees for borers if necessary.
• Watch for fall webworms on pecans, mulberries, and other susceptible trees and trim out webs as necessary or treat
with appropriate products including Bti.
