What are your suggestions for keeping houseplants healthy during the winter?
Place indoor plants in an area where they receive the maximum amount of light, but in some cases direct sun may be harmful. Some protection, such as a thin curtain or special sunshades, may be necessary. Turn your houseplants regularly to keep them from becoming lopsided and gently pinch them to keep them shapely.
Group plants together to increase the humidity level during the dry winter months. Potted plants can be placed on a shallow tray filled with pebbles that are kept moist to increase humidity. Although it is very helpful to increase the humidity, do not overwater. Most plants want to dry out and then be watered thoroughly. Be sure to have adequate drainage such as perlite or sand in the potting soil mix.
Like selecting a plant for your outdoor space, there is no substitute for choosing the right indoor plant for a specific growing spot in your home.
