Know before you buy
Black lava rock is primarily used to improve soil structure and drainage. Its coarse texture prevents soil compaction, which allows for better oxygen circulation around the roots and helps prevent root rot.
Yes, you can use it as is for many bonsai species. However, because the grain size ranges from 3mm to 6mm, some growers prefer to sift it to achieve a more uniform particle size depending on the specific needs of their tree.
No, this component is designed for fast drainage and has a low moisture retention level. It is intended to be a structural amendment rather than a water-holding medium.
It is highly versatile and suitable for most bonsai varieties, especially those that require excellent drainage. It is particularly effective for species that are sensitive to 'wet feet' or root suffocation.
A 1-gallon bag is typically enough to amend soil for several small-to-medium bonsai pots. If you are repotting a single large specimen, you may want to keep extra on hand for future maintenance.
