Simetufy 2.2lb Lava Pebbles, 1/5 Inch Decorative Gravel for Plants, Terrarium Rocks for Indoor Pots, Cactus, Top-Dressing Volcanic Rocks, Drainage for Potted Plants

Great size rocks to put under soil for plants. Small enough so water can trickle around the rocks when piled up. Great size bag for easy storage, too. Never bough rocks online until now... and it was easy and better rocks than wanted.

It's rock, what else can I say? Perfect size and quantity to layer in my drip tray for my cacti.

I use this in the bottom of planters to help with drainage

I keep my Chinese Elm Bonzai in a bed of this kept damp and it really helps to hold the moisture for the bonsai. It's perfect for humidity trays and looks lovely !

When I decided to replant my flowers, I took a different approach. And I went with adding lava rocks to my soil. I love it it helps the The roots of my plants not to get root rot because the drainage is so much better.

These are my favorite kind of rocks for top dressing my succulents. They aren't like smooth River rocks, instead they are quite pourous. They don't trap water down in the pot, rather they allow the soil to breathe and dry out quickly. They also are perfect for adding some extra drainage into the soil. Overall, I'm very happy with this bag. It looks great on top of the soil and also helps improve drainage. I'd definitely recommend it!

Looks great on my cactus

When I ordered them I didn't realize they were coming from China, ridiculous.
