What zone is Brantford Ontario, for growing purposes?

Question

I am wanting to grow a Japanese red maple.

Answer 1

Your hardiness zone is 6a, with minimum temperatures of -23 to -21 C (-10 to -5 F). Japanese maples are typically hardy to zone 5 or 6 depending on the variety, so you should be able to grow one. I would still take some precautions in winter, such as mulching heavily.
