What is the proper temperature for houseplants during the winter months?
Most houseplants grow well with daytime temperatures of 65 to 75°F and night temperatures of 60 to 65°F. Temperatures below 50°F or rapid temperature fluctuations may harm some plants. Keep houseplants away from cold drafts, radiators, and hot air vents. Also make sure houseplant foliage doesn’t touch cold windows.
