Use it alone when
- Your Monstera gets strong indirect light
- The pot has drainage holes
- The mix dries at a reasonable pace
- You do not routinely overwater
Add extra aeration when
- The pot stays wet for many days
- Your home is cool or low-light
- You are using a deep decorative planter
- Your watering style tends to be frequent
Why perlite helps
Perlite creates pore space and reduces compaction. Espoma describes its perlite as 100% perlite with no additives and specifically recommends it for improving heavy potting soil.
Do not turn the mix into gravel
Monstera still needs some moisture retention. The goal is an airy mix that holds some water—not a mix that drains instantly and stays bone dry.
FAQ
Should I add orchid bark too?
You can if you want a chunkier aroid-style mix, but it is not mandatory for every healthy Monstera.
How do I know the mix is too wet?
If the pot remains heavy and damp for a long time, yellowing appears, or fungus gnats persist, reassess drainage and watering.
