Red/Maroon 1/4 inch Horticultural Lava Rock Soil Additive for Cacti, Succulents, & Plants - No Dyes or Chemicals - 100% Pure Volcanic Rock (2 Gallons)

I ordered this after watching a video from some cactus growers in Ireland( Cactimania and Desert plants Of Avalon) who advocate using equal parts regular potting soil, Pumice, and lava rock. Ireland is a very humid place, so a very well draining soil is needed to to prevent root rot in cacti and succulents. Cactimania also uses lava rock as a top dressing on his pots. After using this for about six months, I've found it a very useful soil additive to my cactus soil. I've also found it works very well as a top dressing. Previously, I had used 1/4" quartz gravel for top dressing, but that has become rather hard to find in my area. I find that lava rock works even better. I intend to make this a permanent component of my potting supply shelf.

Price is a little expensive but well worth it. Nice small clean rocks! I originally ordered with AA shop lava rock. What I got from them was not the size advertised. A bunch of big rocks as in 2inch+ mixed in with smaller ones. Package was super dusty and dirty compared to these rocks. They even included a cool little tool to help un root, move soil or rock, ect. Defiantly worth the extra money :)

Bonsai Jack is consistently top notch. uniform size,not dust,great packaging.. plus always supplies free plant sticks(metal),ph test strips. and vinyl glove amazing will use them every years for all my base supplies rare high quality company

I use this soilless substrate along with a mix of Akadama and Pumice, using different ratios, but usually between 25%-40% is this lava rock. I like it so much because it gives the soil structure and doesn’t break down at all, so it can be reused. It holds a bit of water along with providing excellent aeration and drainage. This brand doesn’t have much dust, so very little is wasted. I will continue to use this lava rock with all of my Bonsais.

Expensive, but I need it. I mix this with Hoffman Cactus Soil. Ratio is 5/1 (soil/lava). I've noticed a distinct difference among my dwarf sansevieria in a short period of time. Coloring is more pronounced in the variegation and leaves shinier. Growth is slightly more rapid, though sansevieria tend to be slow growers. I think this will do the trick to avoid root rot caused by soggy soil. Root rot is one of the few ways you can kill these tough plants.

I was hoping it would cover the soil in my water lilies that I just re-planted. Probably should have gotten more because a lot of soil escaped. I won't really know until spring if my water lilies thrive.

Very clean and true to the sizes as advertised.

I like this lava rock a lot, I use it as part of my succulent and cactus mix to add drainage. It’s beautiful as a top dressing as well. I’ve bought this product several times and it’s always a good buy!

The product is nice and clean, and has a very low TDS, which is extremely important for any carnivorous plant grower. Will be buying more of it.

Just know that it's small red rocks. If this is what you need for you succulents, rather than soil, go for it.

Good and excellent product I’ll definitely buy again

Great quality, consistent size

Good but not the best
