Where to buy potting media

(Question)

I am having problems locating the following in Toronto, for ferns, orchids and violets. Where can I buy the following ( horticultural grade) products?

Charcoal, medium coarse sand, mica, sphagnum Moss (Lee Valley carries low grade New Zealand), fir bark, etc. Promix does not include all the required ingredients, for example, for orchids (and the bags I purchased cost $10 each). Any assistance will be appreciated.

You might want to try contacting a company listed on the Landscape Ontario website for such information.  Garden centres in the Toronto area might also be able to help.  Unfortunately, we generally don’t have much information regarding sourcing of materials.
