Nepeta newbie with a few questions
I got some catmint of an unknown variety from a neighbor last year. It's already up and blooming (very pretty) and claiming a good deal of space, and I have the feeling it's going to start crowding out its neighbors. Does yours do that? Do you thin it now or just keep cutting it back or what? Also, do I shear it after the blooms are spent and will it keep reblooming? Thanks!
