- Prepare beds for fall planting by adding organic compost.
- Dig and divide oxblood and spider lily bulbs while in bloom or when they just finish.
- Mulch about 3 inches to prevent weeds and protect against winter damage.
- Plant cool-season leafy vegetables such as lettuce, spinach, broccoli, cabbage, kale, collards, dill, cilantro and parsley
- Trim hedges and shrubs last time before winter.
- Plant bluebonnets and other wildflowers. Barely cover the seeds and firm or tamp down the soil.
- Stop shearing fall blooming perennials such as garden mums, cigar plant, and Mexican bush sage to allow for fall blooms.
- Prune roses (Labor Day!) for nice fall bloom. Do not fertilize. Most antique roses and shrub roses only neat a light shearing to shape them.
