What we liked
- + 1/4 inch screened lava keeps bonsai soil fast draining
- + Bonsai Jack grit is sold dust-reduced for cleaner mixes
- + Lava adds weight that helps stabilize tall trees in pots
Trade-offs
- - Priced higher than bulk landscape lava rock
- - Only 2 dry quarts, so large mixes need several bags
