- Indoor vs. Outdoor Use: Potting mixes designed for indoor versus outdoor use may differ in moisture retention and pest resistance, so select accordingly based on your growing environment.
- Pest Prevention: Some mixes are formulated to reduce common soil pests like gnats, which can be a concern for indoor hosta cultivation.
