What we liked
- + Pumice keeps soil open so roots get oxygen after watering
- + 4QT bag covers several repottings or a large mix batch
- + Lightweight pumice keeps pots easier to move than heavy grit
Trade-offs
- - Sift out any fine dust before mixing into potting soil
- - Pumice floats when first watered and can wash out of shallow pots
