Hey Bo! :)
Portland Nursery (SE Division center) has Foliage Pro. I think they sell the small bottle for $7 or $8.

I'm confused :-) Foliage Pro is a liquid fertilizer and copper fungicide is, well, a fungicide.......two very different products.

Fixed copper fungicide or copper sulfate fungicides are pretty common products and most retail garden centers carry them, especially here in the NW with all our fungal issues and because copper based fungicides are considered 'natural', if not organic. Should be able to locate them in the garden supply department of any box store also. Be cautious when using a copper fungicide during the growing season, as there is a possibility of causing phytotoxicity with some plants.
