DIY Perfect Potting Mix for Coleus and Other Houseplants

Your coleus cuttings rotted in store-bought soil containing leaf mold. The solution? Make your own well-draining mix—it's easier, cheaper, and far more reliable.

Two Proven Recipes

Recipe 1: From Scratch (Equal Parts)

• Compost
• Peat moss (from compressed bales)
• Perlite (white volcanic pellets—not vermiculite!)

Recipe 2: Enhanced Store-Bought Mix

• 2 parts inexpensive potting soil (usually compost/peat with minimal perlite)
• 1 part additional perlite

Why Perlite, Not Vermiculite?

Both are volcanic products, but vermiculite breaks down over time, losing its aeration properties. Perlite remains stable indefinitely, maintaining crucial drainage and oxygen flow to roots.

The Root Rot Connection

Your coleus likely suffered from root rot caused by constantly wet soil. When roots lack oxygen, they die and rot. The perlite creates air pockets that let roots breathe between waterings.

Pro Tip

Water only when the top inch of soil feels dry. The pot should feel noticeably lighter. Good drainage isn't just about the mix—it's about the watering habit too.

With this mix and proper watering, your next coleus cuttings will root vigorously and thrive.
