Direct answer
A pot can remain wet because of the medium, container geometry, drainage openings, irrigation, weather, crop uptake, or several factors together.
Do not diagnose from the surface alone
The top may appear dry while the lower profile remains wet. Check the root zone and drainage path.
Common contributors
- Fine or compacted media
- Shallow container geometry
- Blocked or inadequate drainage openings
- Over-potting
- Irrigation more frequent than crop use
- Low light or cool conditions
Do not add one component blindly
Pumice or perlite can change a recipe, but correcting an existing container requires understanding the full system.
Connected planning path
Apply the science to a real growing system
Container dimensions, crop, irrigation and duration should lead the material decision.
