Looking for SP's that provide edging or for anyone's recommendations/reviews for some that do it well
Usually, one would go to Home Depot, or Canadian Tire for Lawn Edging.
I would humbly suggest that you develop a rapport (street creds) with the board before asking questions, point blank.
I have one favourite of mine in Durham Region who provided edging when I was more active. However, some people bring out the drama when her name comes up, and I have refrained from mentioning her name.
BTW, welcome to TERB.
