Humidity for Indoor Plants

To increase humidity for indoor plants, set a small plastic cup beside them and fill it with water. As the water evaporates, it humidifies the air immediately surrounding the plant. Sometimes this small amount of water makes all the difference. Another easy way to provide better humidity for houseplants is to use a mister to deposit a coating of small droplets of water over the leaves. It is best to mist in the morning, so that the leaves will dry before nightfall. Do not mist the plant where any foliage is exposed to direct sunlight.
