    Tips & tasks – August

    Water lawns and garden beds early in the morning to allow foliage plenty of time to dry before nightfall.

    Container gardens will benefit from a light application of all-purpose fertilizer.

    If petunias have grown long and shaggy, cut them back and give them a dose of fertilizer. They should bloom again quickly.

    If squirrels and birds go after your ripe tomatoes, pick them while they are still green and allow them to turn red indoors. For best quality, don’t store fresh tomatoes in the refrigerator.

    Make sure spring-planted trees and shrubs get plenty of water during hot weather.

    Keep cutting the spent flowers of annuals so they will continue to bloom into the fall.

    To conserve soil moisture during hot weather, replenish mulch in annual and perennial beds as necessary.

    Begin planning a fall garden. Spinach, lettuces, radishes and other fall crops will mature when the weather turns cool.

    Begin clean-up of summer vegetable beds. Remove any decayed or dying foliage to prevent diseases from taking hold.

Pruning oakleaf hydrangea

Our oak leaf hydrangea bloomed beautifully this year, and the flowers have turned pink or brown but they’re still on the plant. The shrub is huge and needs to be cut back. Is it too late to prune it now? I want to make sure it blooms again next year.

oakleaf hydrangea Hydrangea quercifoliaLandscape designer and plantsman Troy Marden, in his book Southern Gardener’s Handbook, says that pruning oak leaf hydrangea can be “tricky.” It blooms on old wood, and next year’s buds may already have begun to develop. If you prune it now, mid-August, you likely will be cutting off some of next year’s flowers. Best to prune the plant shortly after the flowers have turned from white to beige, he suggests.

There’s no reason you can’t remove any dead branches or stems now, though. Use sharp pruning shears, and cut dead twigs and stems off close to the branches. In fact, hydrangea experts note that dead stems should be removed every year.

Shortly after the shrub blooms next spring, consider removing about a third of the older living stems at ground level, which should revitalize the plant.
