Pumice for Bonsai, Succulent, Cactus, Alocasia, Monstera, and Tropical Aroids | 2 Quarts Bag | 1/4” Particle Size | The Bonsai Supply

I wanted a cactus area with different kinds of rock and this worked out perfectly in several areas. I am not finished with this part of the yard yet, but I also want black and red rock so I am taking my time planning it. These mini white rocks show up so well. Just the right size and clean with no dust.

Good stuff, I like it because it’s very clean and uniform. Great for mulching the pot.

I used this as an ingredient in my terrariums and it works really well.

Perfect price and perfect size for making a nice soil mix for cactus soil.

Good grain size for cacti soil additive. Yellows if used as a top dressing, better for in situ

This was the perfect size I was looking for without any sifting. A bit pricey? Sure. But, the convenience and quality of the product is perfect. There is pretty much no dust at all....some on the packaging plastic but when you pour it, nothing. Will buy again when needed.

Pumice doesn't give me nasal and lung problems like perlite does even when I wear a mask. It isn't dusty at all, let alone like perlite. It doesn't float up out of the soil like perlite does. And it makes a wonderful cover layer that slows evaporation and keeps fungus gnats out of your soil. I mix the same amount of pumice into my potting soil as I did perlite, and the drainage is great. I am just delighted to have found this product.

Great for making bonsai soil 10/10 would recommend buying this.
