Many Northerners love taking their air plants outside for the warm months but since air plants are a tropical species, they need to be brought indoors when the nights start to fall below 40 degrees. Once brought inside, your air plants will need some special attention to adjust to their indoor environment.
The main differences between the indoor and outdoor environments are temperature, humidity, light, and air circulation.
Air plants thrive in temperatures between 65-85 degrees. Chances are, if you are comfortable in your home, your air plants will be comfortable too. Not much to worry about here.
Homes heated by forced-air furnaces, fireplaces, and radiators tend to be very dry in the winter. Imagine the extra amounts of hand cream that you need to keep your skin from cracking on a winter's day. Your air plants might also suffer under these dry conditions. To remedy, we recommend adjusting your watering schedule. Curling leaves and dry tips are signs that your air plants may need more winter moisture. Be sure to give their weekly water bath but you may need to supplement with an extra misting once a week. Avoid placing your plants near drafty windows, vents, and air returns. Placing a tray of water near your plants is another strategy for increasing the humidity.
Your plants will still need bright light when indoors. Due to the lower sun angle, most plants tolerate brighter winter sun when they would be otherwise burned during the summer. Optimum conditions are within several feet of a south or west facing window. If natural light is limited, the next best option are fluorescent and grow lights since they provide "blue light" that is needed by plants. Be careful when displaying your plants near incandescent light bulbs since they can get very hot and burn the plants.
Do not place your plants in tightly closed or cramped containers. Air plants need fresh air to circulate which helps them to absorb nutrients. Please check out air Air Plant Care Video Series for more air plant care tips!
