Overview

It is important to control humidity in your home to maintain a healthful environment for indoor plants to thrive. Too much moisture and your plant can rot, grow mold and succumb to a disease. Not enough moisture and your plant can dry out.

Placement

When it comes to humidity, where you place your plants in your home can make all the difference. Plants near drafty areas of the house or near radiators will be more susceptible to low humidity. Plants above your kitchen sink, near an aquarium or in bathrooms will be exposed to higher humidity levels. Move your plant according to your plant's needs. If your plant needs less humidity, move it near a radiator. If it needs more humidity, move it near the kitchen sink. Wherever you place your plant, you will need to consider the amount of light your plant needs to thrive. You might need to try a different strategy to control humidity if moving your plant compromises its light requirements.

Strategies

For low humidity problems, you can try grouping your plants so the plants can gain moisture from the evaporation of the nearby plants. You can also place your plants on a tray filled with water and pebbles. Be sure the plants are not sitting in the water, but rather above the water. In addition, you can decide to use a humidifier to help raise the humidity in your home. Place it near your plants. For high humidity problems, place a light near your plant and allow it to stay on during the daytime hours only. The closer the light is, the more it will dry out the area around the plant. For safety reasons, your plant's foliage should be at least 12 inches from the light bulb. If overall humidity is a concern in your home, you can always use a dehumidifier.

Terrariums

While you can purchase a plant terrarium to increase humidity, you can just as easily make one yourself. Simply use a fish bowl, glass bowl or jar and place it upside down over your plants. You can also use clear plastic, but it should not be tinted as that will hinder light from reaching your plant. If you find that your plants are too moist and start to rot or grow mildew, then you can modify your terrarium into being an open one, rather than a closed one. Use a clear plastic container a cut off the top. You will need to water more often, but it will prevent the plant from dying.
