    Fertilize annuals

    Fertilize salvia and chrysanthemums with liquid plant food. They will reward you with lots of blooms later this fall.

    See Fertilizing Annuals.

    Deadhead perennials

    Examine your flower beds for tired out perennials like Shasta daisy, black-eyed Susan and purple coneflower. You can cut off dead flowers and brown foliage to neaten the plants for fall.

    See Deadheading

    Save excess basil

    Preserve excess basil leaves by pureeing in a blender with a little water. Freeze the slush in an ice tray and use the cubes in your wintertime spaghetti sauce.

    Spot spray the broadleaf weeds in your lawn with a herbicide labeled for their control.

    Try a muscadine

    You can’t live in the South without trying a muscadine: Pop it in your mouth, suck the pulp out of the skin, enjoy the juice, then spit out the skin and seeds. What a delicious mess!

    See Growing Muscadines

    Plant peony

    It’s a great time to plant peony roots. A good, old-time favorite is ‘Festiva Maxima’. For real excitement, plant a tree peony and get huge blooms next May.

    See Growing Peony in the South

    Prep for fescue planting

    Before planting fescue seed, wipe out weeds with a fast-acting but short-lived weed killer. Use glyphosate (Roundup, etc) now; you can seed in seven days.

    Fertilize bermuda

    Bermuda lawns sometimes, but not always, benefit from a “winterizer” fertilizer application. Do it now when growth has slowed but before frost turns the grass brown.

    See Fertilizing Bermuda Lawns

    Apply pre-emergent

    Did chickweed and annual bluegrass run rampant in your lawn last spring? Now’s the time to put out a pre-emergent weed preventer on lawns you’ll not overseed this fall.
