  • February garden tips & tasks

    Fight cabin fever by getting on a sunny day to pick up sticks, leaves and other garden debris that has accumulated.

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

    Plant a tree if the soil isn't frozen. Dig a hole that is slightly wider than the tree's root ball, but no deeper. Place the tree in the hole; replace the soil and water it well. Add mulch, but don't mound it up around the tree's trunk.

    A Valentine's Day bouquet of roses will last longer if you cut off the bottoms of the stems at an angle bfore you place them in lukewarm water in a clean vase. Remove the lower leaves from the stem before you place the bouquet in water.

    Dig winter annuals out of the garden beds: deadnettle, henbit, chickweed and other unwanted plants before they take over the beds.

    Cut back or mow over liriope (monkey grass) before new growth begins.

    Don't overwater your houseplants. Before you add water, check the soil's moisture level by sticking your finger into the soil.

    Provide nesting boxes to welcome birds to your garden Cavity-dwelling birds may start a family in a simple box with 11/2-inch entry hole.

    Grow your own transplants indoors under lights. Start seeds of cool-weather plants now to have sturdy transplants to set out in a few weeks.

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).
