Many foliage and flowering houseplants suffer in dry conditions causing the leaves to shrivel and fall. Here are some ways to help control the humidity around you indoor plants, avoid dry air and help them to thrive!

Fill the large pot a quarter of the way with peat, place the houseplant (in in its pot) on top, and fill the space between the pot and the outer, larger, container. with peat. Then keep the peat thoroughly and continuously moist.

Dish moist air bath. Half fill a dish, or saucer, with pebbles and then add water to nearly cover the stones. Stand the pot on the stones. Add more water from time to time to replace evaporation loss.

Steam bath. Several indoor plants respond to an occasional steam bath. This is especially true when leaves droop. Put a block of wood inside a basin, pour in boiling water until it comes to just below the top of the wood. stand the pot on the block for five minutes. then, replace the pot in its growing quarters.
