I have a few plumeria seedlings that I need to repot, and I was wondering if decomposed granite would be a good addition to add for drainage? I'm trying to find a better potting mix for my plumerias.

I have heard of people using that yes. No experience with it myself though.

Thanks Hetty. I saw some at Lowes and I wanted to try it out, but I was afraid of it possibly compacting. I want to make a potting mix with decomposed granite, perlite, some composted cow manure, and a little Miracle Gro potting soil.
