Now is a good time to install a bahiagrass lawn. It is probably the most carefree of the home lawngrasses. Mole crickets are the only major problem, and good controls are available. It is the only practical grass for a lawn without irrigation. The turf turns brown in a drought, but grows back when it rains. Watch for sod web worm and army worm damage. These are caterpillars that feed on grasses and usually are a problem on Bermuda and St. Augustine lawns. They will attack all types of lawns if the population is high enough. The grass will look as if it has been mowed very low Treat damage areas with an approved insecticide. It may not be necessary to treat your entire lawn . Spot treating reduces the amount of insecticide being applied to the environment.


Many perennials can be started from saved seeds, such as salvia, violets, ruellia, lion's ear, gerbera daisy, butterfly weed, and blanket flower. Let seeds dry on the plants. When pods open it is time to harvest. Bring inside and let dry on screen or cheesecloth. After a few days, put into a plastic bag or a jar and label. Keep the seeds in the vegetable section of the refrigerator. Use within one year. Do not store in the freezer!


Cut back unwanted limbs to a branch angle or the trunk. Remove old fronds and seed stalks from palms. Do not apply paints or coverings to wounds. Let them heal naturally. Remove old seedheads from crape myrtle trees to encourage additional blooms.
