Are questions on Bonsai Trees suitable for the gardening and landscaping exchange? Would they be considered off-topic?
Are Bonsai Trees within the scope of gardening and landscaping?
I do not believe they would be off-topic, at least not anymore off topic than discussion of house plants, window boxes or other non-gardening horticulture questions. I think that pretty much any question having to do with plants is going to be welcome here.
