The Dallas County Master Gardener Association, through the Texas A&M AgriLife Extension Center, has a list of garden tasks for the month of September. Among the tasks for this month:
Planting
- Divide and re-plant spring blooming perennials such as Iris, yarrow, daisies, daffodils, and daylilies (late September to early October).
- 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.
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.
Plant Care
- 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.
