If you didn’t prune your everblooming roses by about one-third in late August, do it right away. Then add fertilizer -- we recommend Rose-tone or Fertilome Rose and Flower Food – and keep the bushes well watered for a beautiful fall bloom.
Continue a spray program to prevent blackspot and powdery mildew. We recommend Fertilome Systemic Fungicide II, or Rose Shield.
Dig and divide Louisiana irises now through early October, replanting as soon as possible. Don’t let them dry out.
Get your soil tested. You can pick up LSU AgCenter kits here at the nursery.
Begin planting cool-season annuals, such as pansies, dianthus, alyssum and snapdragons, late in the month. Refresh your beds first with Vital Earth compost and Fertilome Bedding Plant Food.
Purchase spring bulbs late in the month for best selection but delay planting until October/November.
Build a compost bin or set aside an area for a compost pile. You’ll have plenty of fall leaves soon to fill it.

Spray trees affected by scale insects with Hi-Yield Systemic Insect Spray.
