I have a small to mediumish tree stump to get rid of and I know saltpeter will cause it decay.
That being said I know its a restricted substance and need a licence to be sold.
Anyone know of any place to buy some?

I believe TSC may sell it. I use to buy it at Shopper's Drug Mart.
Lots of places sell it. It's only restricted if buying over a certain quantity. Hydroponic stores sell it for sure.
Walmart has it available for pickup

rent a stump grinder from a tool rental store. potassium nitrate is restricted because its a bomb making material you're probably already on a list.
This is inane. Saltpeter has other legitimate uses than manufacturing explosives.
You likely buy a more dangerous substance regularly for your automobile without ending up on a list.
That's funny. My Stepfather had a can of saltpetER they gave them in The British Navy. It for sure makes a tree trunk soft.
