I believe the Houston Garden Center chain, which is all over Houston, Pasadena, Katy, etc, carries all of those. THey are pretty reasonably priced, too.

Well, I'd be really impressed if you find a store that has all of those things!

It took me a month to find just the 1:1:1 ingredients and of course they are at 3 different stores but well worth the effort. You'll find the gran i grit at a grain/feed store, the MVP Turface I found at an irrigation store (Ewing Irrigation - don't know if they have Houston stores), and I had to screen the Home Depot Sure Stay "Premium Pine Mulch" to get my fines. If you end up doing that, you can use the finest remaining particles in place of peat moss in the 5:1:1. Oh, and wall mart has perlite.

Good luck to you on your quest, it is like a treasure hunt and so exciting when you actually find the stuff!

I have trouble finding anything I would consider pine bark fines. Now I buy pine bark nuggets and send them through a chipper which works well but I happen to be lucky enough to have one to use.
