  • January garden tips & tasks

    Begin a garden journal. Use it to jot down ideas and lists of plants you want to grow this year.

    Keep bird feeders filled to attract a wide variety of winged visitors to your garden in winter.

    If you bring home new houseplants, protect them from the cold air on the trip home. Once you bring them in, keep them separate from other plants for a few days to watch for pests.

    When the ground freezes and thaws, plants can be pushed out of the ground – a process known as “heaving.” If this happens, tuck the roots back into the soil and cover the area with a layer of mulch.

    You can grow herbs on a sunny windowsill indoors, but pinch them back regularly to keep them from getting tall and “leggy.”

    Birds also need water in winter, so provide water in a birdbath or shallow pan and change it frequently.

    Winter is a good time to have the soil in your lawn or garden beds tested. The Extension Service in your county can provide materials and instructions for testing.

    Watch for pests on houseplants and tender outdoor plants that spend the winter indoors. If you see evidence of aphids or scale infestations, take action immediately to keep them from spreading to other plants.Save the date

    Planners of the ever-popular Nashville Lawn & Garden Show announce that next spring's show will be March 2 - 5, 2017 at The Fairgrounds Nashville. The theme will celebrate Gardens of the Future with garden displays, lectures, vendors, floral designs, and special features for children. The centerpiece of the all-indoors event is, as always, the walk-through, interactive garden displays from some of Middle Tennessee's top landscape and gardening companies. Free lectures are planned each day on a range of garden-related topics, and visitors can shop the Marketplace with more than 150 vendors.

No-fly zone

QUESTION: Some of the plants I brought in from outdoors seem to have tiny white flying bugs all around them, and are a nuisance. What are they? And what can I do about them?

 

Schefflera can play host to whiteflies.

These are likely whiteflies, and they often ride in on plants that spent summer outdoors. They’re more than a nuisance; they feed on the plant’s juices and can cause the leaves to turn yellow and die. The insects that are flying are the adults, and if you look at the undersides of the leaves you may be able to see the tiny yellow eggs and larvae.

Whiteflies feed on dozens of plant species and they reproduce quickly, so the problem could get out of hand quickly. To get rid of them, remove the badly infested leaves, then rinse the plant thoroughly and spray with an insecticidal soap. Be sure to treat the undersides of the leaves. Repeat the spraying every week or so.

Next fall, examine them closely to be sure there are no pests hitching a ride. Wash the leaves and treat the plants before you move them indoors. There are several other insect pests that you should watch for:

Aphids: they usually gather in clusters on tender young leaves. They also feed on a plant’s juices. Insecticidal soap, or washing with water or rubbing alcohol, is usually effective.

Mealybugs: You may see white, cottony clusters on stems or leaves, or where the leaf joins the stem. They also feed on the plants, so get rid of them by rubbing them off with water or alcohol.

Spider mites: They are barely visible, but you’ll certainly notice the damage – light-colored, speckled areas on top surfaces of leaves. You may see webbing stretching between leaves if there is a heavy infestation. Wash the plant with soapy water, and treat with insecticidal soap a day or two later. It may require diligence and several applications to control these insects.

UT Extension provides a booklet at its Web site that addresses these problems and more: Insects and Related Pests of House Plants (PB1157).
