Most houseplants do best in potting soil that allows water to drain easily. Stagnant, sticky soil clings to plants and can rot the roots or allow harmful fungal growth. A variety of bagged mixes are available commercially, but you can easily make your own mix at home. Homemade mixes are often better because you control exactly what goes into the mix and in what amount. This is especially useful if you have several different kinds of houseplants--you can create a base mix and add ingredients as necessary for individual kinds of plants.

- Large mixing bowl or bucket

How to Make Well-Drained Soil For House Plants
Put your garden gloves on and pour dry compost and the garden soil into the mixing container. Break up any clumps and remove anything that looks like a seed, weed or bug.
Pour in the entire bag of perlite and blend this in with the compost and soil. It’s best to do this with your hands rather than a stirring tool--you’ll be able to mix it up better.
Toss in a little peat moss. Add it to the other ingredients bit by bit just as if you were adding ingredients to make a cake.
Pour in some vermiculite and work it into the mixture. Add a little more until the whole bag is poured into the mixture.
Shake or stir the potting soil mixture well. Divide it into plant pots for re-potting plants.
