All plants need air, but houseplants don't get much fresh air when it is cold outdoors. Indoor plants suffer if they are too close to radiators, vents, fans or open windows because they dislike drafts: Move them back from windowpanes if it is frigid outside.
Ways To Produce Humidity In Our Dry, Winter Homes
Many of our foliage plants are native to tropical rain forests and love humidity. Here are some ways to create humidity for our houseplants (and ourselves!):
- If there is enough light, they thrive well in a bathroom or kitchen where steam is produced by either hot showers or cooking.
- Try grouping  houseplants together on a waterproof tray filled with pebbles that sit in water. Place the pots on top of the pebbles where it is dry. The water will keep the air moist and the plants happy.
- Home humidifiers, indoor decorative fountains and plant misters can also improve humidity levels.
Some DON'TÂ Like It Hot
Most home temperatures are between 68 to 72 degrees and foliage plants enjoy that range. However flowering plants such as azaleas and cyclamen like cooler temperatures. Flowers on plants last longer if they are kept cooler at least part of the time, so lower the thermostat at night. Plants like gardenias and Christmas cactus won't set buds unless they have cooler temperatures, but once buds are set they will tolerate normal indoor conditions. Withhold water from the cactus to force it into bloom.
