Give Seeds TLC
To get seeds up and going in this heat, give the seed furrow a deep soaking prior to planting. Then water the seeds in well after planting. A little shade covering over the row can slow drying of the soil and reduce soil temperature. A section of shade cloth or row cover suspended over the row works great.
Keep Watering Turf
Give your turf a good watering every 5 to 7 days. This will keep it healthy and dense, and will help to deter weeds. Many winter weeds will begin germinating in mid to late September in the mid to upper Gulf Coast area. If your turf is thin, weed problems will be much worse.
Shear Herbs and Summer-Blooming Salvias
Shear back herb plants that are ragged looking from the effects of summer. They will respond with new growth in the coming months. Summer-blooming salvias, such as Salvia greggii, S. farinacea, and 'Indigo Spires' can be cut back now to encourage another great show in fall.
Start Cool-Season Transplants
Start seedlings of cool-season veggies and flowers indoors now for a jump on the season. In six to eight weeks they will be ready to transplant out into the garden when the weather turns a little more hospitable! Wait a few more weeks to start lettuce and spinach transplants. They reach transplant age faster and need to go out into the garden a bit later too.
Trim Roses for Better Fall Bloom
Cut back repeat-blooming rose bushes by about a third in mid to late August. They will regrow and on a good show in October. Keep foliage healthy so the bush can put all its energy into setting blooms for this fall. Black spot, powdery mildew, aphids, and mites can burden a rosebush and reduce fall blooming if left unchecked in the summer.
