How can I find horticultural cornmeal in Montreal?

They still don't have it. Thank for the answer

This the first time that I experiment this web site and I'm surprized at the feedback thank you all.

Some Home Depots are better than others. Mine unfortunately, and there is no way say this nicely, but they are crap. Trying to do away with all cashier's, just like Wal-Mart, and have it be all automated. I always buy odd bits that don't scan. Not only that, I pay cash and don't use debit or credit cards. Anyway, see if they will order for you. Another option would be to try a high end or independent nursery. Typically they are more apt to please their customers and will order for you if not in stock.

horticultural cornmeal is the one they use to combat fungus on rose bushes and other culture. what I need it for is to soak my feet in the cornmeal mixed with hot water to heal the nails of my feet. it's supposed to be miraculous
