The air in many homes, especially in the winter when heating units are running, is very dry, which can be stressful for plants. Humidity is important for plants because it helps them regulate moisture loss. The dryer the air, the more moisture the plant will lose. If the tips of a plant's leaves are turning brown, or if its flowers are dropping off prior to opening, it could be a sign that the plant is stressed and requires additional humidity. There are several ways to provide more humidity to plants, and using a humidity pot is one of the easiest. This process is also known as double potting.
Place a 2-inch layer of moistened peat moss in the bottom of the container.
Place several small potted plants or one large one on top of the peat moss and pack more moist moss around and between them. Place the pot on top of the plate or tray to catch any excess moisture.
Use the misting bottle to keep the peat moss consistently moist.
Empty the plate or tray under the larger pot frequently.
