Potting Mixes

Whether you're repotting a houseplant or starting a new container garden, it's important to use the right potting mix.

You should be able to find several types of potting media at your local garden center. Soil from your garden often doesn't contain enough organic matter.

Commercial potting mixes typically include a blend of ingredients like sphagnum peat moss, processed bark, sand, perlite, or vermiculite. The balance of these ingredients will affect the density of the potting mix, as well as its ability to hold water. Some products even include moisture-holding crystals or fertilizer.

Finely ground mixes are good for starting seeds, while medium and coarse mixes work for most other gardening projects. When in doubt, read the product label so that you can find the potting mix that's perfect for your project.

It's best to replace the media in your containers at least once a year, and to re-pot plants when they need more room.
