Can confirm, same deal in Maine/New Hampshire. My kiddo picked one up to try bonsai (solid bonding time) so I’m taking him to a repotting class at NEBG with it. The trees are $16 iirc… 3/4” to 1-1/4” trunks no noticeable grafts but he hasn’t dug down into it yet as we’re waiting for the class. Will post photos post repot.FYI, the Home Depots in NY and NJ are selling 1 gal mugo pumilio, apparently from seed stock as there is quite a bit of variation in growth habit and needle color between trees. I picked up a Hagarumo lookalike- some really intense budding behavior and short needles. The root base isn't the best, but at minimum it's an interesting plant.
