I'm having a damn hard time finding Promix BX around here. Might have to start calling the small specialty garden centers this weekend but I'll see what the local Ace has on hand. They probably don't carry the selection they might in the heart of Texas though
. The
really local Ace closed down about 5 years ago for an apartment-over-retail development so the nearest one is up a ways.
I've been using Dr Earth Pot of Gold but not sure it's worth the extra money. I've got a bag left but I can use it for the pineapples!
