Best Soil for Monstera: What Actually Works
The best soil for a monstera is not soil at all. A chunky, soil-free aroid mix, like Molly's Aroid Mix by Veryplants (orchid bark, perlite, coco chips, charcoal), gives monstera roots the airflow they evolved for, drains fast enough to prevent root rot, and makes overwatering hard to get wrong.
Skip regular potting soil
Dense bagged soil compacts around monstera roots, holds water too long, and is the number one cause of root rot and yellowing leaves.
Chunky and airy wins
Monsteras are aroids: in nature their roots grab onto loose bark and forest debris, not dirt. The mix needs air pockets as much as moisture.
Watering gets forgiving
A fast-draining soil-free mix means an extra watering won't drown the roots. Overwatering stops being a death sentence.
Fewer fungus gnats
Gnats breed in consistently damp organic soil. A bark-based mix that dries between waterings breaks their lifecycle.
Monsteras fail indoors for one main reason: their roots suffocate in dense, wet dirt. In the wild, Monstera deliciosa climbs trees and roots into loose bark and leaf litter, not packed ground soil. Recreating that root environment in a pot is the whole game. That means large particles for air pockets, fast drainage, and enough structure that the mix never collapses into mud.
Monstera soil options compared
| Generic potting soil | DIY aroid mix | Molly's Aroid Mix | |
|---|---|---|---|
| Drainage and airflow | Poor; compacts over time | Varies with recipe and sourcing | Fast-draining, chunky, highly aerated |
| Root rot risk | High if overwatered | Depends on ratios | Low; engineered to resist compaction |
| Fungus gnats | Common | Possible | Discouraged; dries fast between waterings |
| Effort | None, but risky | Sourcing 4-6 ingredients, mixing, storing | None; ready to use |
| Typical cost | $1-2/qt | $3-6/qt once all inputs bought | From $3/qt (25qt size) to $4.60/qt (5qt) |
A DIY blend can absolutely work, most recipes combine bark, perlite, and coco products in similar ratios. The tradeoff is sourcing and storing four to six ingredient bags to pot a handful of plants, and quality varies bag to bag. A pre-blended mix removes the variance: the same engineered root environment in every pot, with beneficial fungi already included.
Frequently asked questions
Can I use regular potting soil for a monstera?
You can, but it is the most common reason monsteras decline indoors. Standard potting soil compacts in containers, suffocates roots, and stays wet long enough to trigger root rot. A chunky aroid mix avoids all three failure modes.
What is in Molly's Aroid Mix?
Orchid bark, perlite, coco chips, and horticultural charcoal, plus beneficial mycorrhizal fungi. No soil, no fillers, and no soil-borne pests or pathogens.
How often should I water a monstera in an aroid mix?
Roughly when the top half of the mix is dry, typically every 7-10 days indoors. Because the mix drains fast and holds air, the exact day matters far less than in dense soil.
Do I need to repot my monstera before switching mixes?
Switch at your next repot, or sooner if you see yellowing leaves or smell soured soil. Shake off as much old soil as possible so the roots sit fully in the new mix.
Does the same mix work for philodendron and pothos?
Yes. Monstera, Philodendron, Pothos, Anthurium, and Alocasia are all aroids with the same root requirements; one aroid mix covers all of them.
