I'm looking into growing a rabbit's foot fern on top of a lava rock because I've seen how well it works. The porous nature of the rock helps retain water, which is great for the plant. However, I'm struggling to find a nice fist-sized lava rock. I've checked out local hardware stores but only found small lava pebbles. Does anyone have suggestions on where I can find a decent-sized lava rock? Thanks!

Have you thought about browsing Etsy? I haven't looked specifically for lava rocks but I've found plenty of unique plant supplies there. Plus, asking around in plant forums can lead to some good local tips!
Check out Petco! They often sell lava rocks as hardscape for aquariums. I got a solid-sized one there for just about five bucks. Definitely worth a look!
I got lucky and found some on Facebook Marketplace! It's a bit of a hit or miss, but there are often sellers who have nice ones. Just be careful with distance, as shipping could be tricky if you're far apart!
