Why perlite is useful
Container roots need both moisture and oxygen. Dense mixes can collapse over time and stay wet too long. Perlite adds lightweight particles that create more air space.
Best use cases
- Improving dense bagged potting soil
- Monstera and aroid mixes
- Propagation blends
- Helping a slow-drying potting mix dry more evenly
What Espoma publishes
Espoma lists the product as 100% perlite with no additives or fillers. Its directions include mixing perlite with heavy soils and using it in seed-starting and root-cutting media.
Limitations
Perlite does not provide meaningful nutrition. It can also float toward the surface during repeated watering, and adding too much can make a mix dry faster than a moisture-loving plant prefers.
FAQ
Does perlite cause root rot?
No. Perlite is generally added to improve aeration. Root rot is associated with root decay and prolonged wet, oxygen-poor conditions.
Is more perlite always better?
No. The right amount depends on the plant and the rest of the mix.
