Dirtco Horticultural Pumice Product Review

The Dirtco Horticultural Pumice boasts that it is some of the best quality and most uniform pumice available.

Ready to use and specifically chosen so that all stones are of a uniform, similar size that helps even drainage and balanced aeration.

Able to help plants and soil retain water but conversely helps improve drainage and prevents waterlogging, this pumice is packaged in a novel pot with a screw-on top.

Being sold in two different sizes (2 Quart, and 4 Quart) and with each chip approximately half an inch, the Horticultural Bonsai Pumice provides the perfect balance of gas exchange, draining capabilities, and moisture retention.

Capable of improving root and plant health and optimizing your growing environment this nontoxic, sterile, and pH neutral soil amendment helps maintain soil pH levels whilst encouraging strong and healthy plant growth.

Perfectly affordable and one of the best-reviewed pumice stone soil amendments available, it is easy to see why this product has been receiving the recent incredible praise it has.
