Gardeners often move potted plants indoors when the weather becomes cool. This can be a good technique, as long as a few steps are taken to ensure that indoor plants remain healthy and vigorous throughout the season. Here are a few tips for how to care for houseplants in winter.

Humidity in homes during winter tends to be lower than what houseplants would prefer.

  • If you have a humidifier, place houseplants nearby.
  • If you do not have a humidifier, there are a couple of solutions. 
    • Group plants together near a damp area such as the shower. 
    • Place a tray of water below or near the plant. However, make sure the pot is raised above the tray and not soaking the houseplant.


Houseplants grouped together near a window
  • Move houseplants away from window sills and drafty areas. Many are subtropical and sensitive to cold temperatures.
  • Houseplants do not like fluctuating temperature areas either; such as fireplaces, stoves, and heat vents.
  • The ideal daytime temperature is 65 to 75 degrees F. The ideal nighttime temperature is 50+ degrees F.

  • Clean off the dust from the leaves monthly. (see Cleaning)
  • If needed, use artificial light such as fluorescent bulbs to provide light and heat. 
  • Ten to fourteen hours of typical fluorescent office-type lighting is considered medium light. High-intensity light occurs within 2 ft. of a south-facing window from Oct. to March.


Woman watering houseplants
  • Reduce the frequency of watering by half.
  • Only water when the soil is dry. Check at least an inch below the surface for dryness.
  • Do not water with cold water; use tepid water instead.

  • Do not fertilize during winter. Instead, wait until spring to begin fertilizing houseplants.
  • Fertilize only if plants show signs of deficiencies.
