Improving Drainage in Container Plants: Why Your Potting Mix Holds Too Much Water

The Problem

Miracle-Gro contains a moisture polymer. Adding vermiculite, peat, or kitty litter increases water retention—opposite of what you want.

Better Mix for Drainage-Loving Plants

Cactus/succulent soil, or
Potting soil without polymer, blended with coarse bark or 1/4" lava rock.

Why Containers Usually Need Slower Drainage

Gravity pulls water down; polymers, vermiculite, peat slow that process—usually desirable. Only change if plants specifically need sharp drainage.
