While outdoor plants enjoy their winter snooze, indoor plants are giving gardeners something to water, feed and care for.

Some indoor plants, especially those in places with little air circulation, are susceptible to powdery mildew, a condition that appears that the plant was dusted with talcum powder.Powdery mildew will usually disappear from plants as soon as they are placed outside in the spring. Plants with mildew also improve if placed outside on mild winter days. Or they can be sprayed lightly with a fungicide such as Daconil. If possible, try to circulate the air with a fan.

Another white substance, mealy bugs, can winter over on houseplants that were outdoors in the summer.

Mealy bugs can be picked off by hand or removed by strong jets of water or insecticidal soap sprays.
