Houseplants in for Winter
It's best to bring houseplants inside when night temperatures start to drop to around 50 degrees. Some plants tolerate cooler temperatures in the 40's, and can remain outside for a while longer. These include Cymbidium and Phalaenopsis orchids, as well as Christmas Cactus.
Houseplants do need to acclimate to the lack of humidity and lower light levels inside the house, so place them near a window and offer more humidity with a pebble tray under the plant and keep the tray moist. Inspect your plants for insects and insect eggs before bringing them in. Spray with an insecticidal soap or use a systemic houseplant insect control even if you're not sure they have them.
Remember, most plants need less water and fertilizer during their winter rest time indoors since there are fewer daylight hours and less than ideal growing conditions.
