Making Your Own Potting Mix

Need to repot your favorite houseplant or start seeds for your vegetable garden? You can buy prepackaged potting mixes at your local garden center, or you can make your own. By making your own potting mix, you'll be able to customize it for the specific project.

Start by gathering basic ingredients like spaghnum peat moss, coarse builder's sand, perlite, vermiculite, and dolomitic lime. Then search online or in books for a recipe that will fit your plant's needs.

If you're starting seeds you'll want a fine, lightweight mix with good moisture-holding capacity, so try a recipe that contains more peat and vermiculite. If you're repotting a cactus, a mix with more sand will provide good drainage.

With a little practice, you'll develop your own favorite combinations.
