Just to document where I can find what constitutes decent soil in the area:
Turface MVP: http://www.wsconnelly.com/turf-and-ornamental/locations.php
About $11 for a 50lb bag
76 & 288
Gran - i - Grit (Grower) - Southern States on Alverser Dr off of Midlothian Tnpk
Permatill - Strange's on Broad St
$3 for 50 lbs or something ridiculous. It comes out of NC
Pumice (Dry Stall) can be found at Southern States off of West Broad also.
Organics can pretty much be found any old place. Looking for soil conditioner and then sifting the bark is best.
I would like to add this article for information also:
