My pleasure, and you're right about the lava rock btw. It's not a good mulch because it heats up, and thus doesn't do the cooling, moisture retention, and natural breakdown that the wood chip mulch does. You'll love working with the Florimulch. It's really great stuff and smells nice too. (I think it does anyway) Spread your mulch fairly thick, because it does settle somewhat, and of course insulates better if it's 2 or 3in. thick as well.
