Lava rock is great! You can even grow plants on it! The main, thing do research! Did you know lime stone can raise pH levels?

I go to a local landscape poace and buy tines if rocks. Last trip, $8 for about 40 lbs. Just give them a good scrub before you put them in. My rule is if I can rub the rock and it flakes off. Its a no go.
