My urban yard has a few too many norway maples creating large amounts of shade. AIUI, norway maples may be allelopathic and create lots of shade. What are some good species that can thrive or do moderately well under those shade conditions? I'm also curious about paw paw tress in particular. Do you think they'd do okay (shade wise) on the edge of the shade created by the maples?
Part of the problem with them is the fibrous root system under the tree that will choke out anything that tries to grow there. They are weed trees, imho, and you'd do better to sell them for firewood and put something better in their place. Many experts list them as one of the worst invasive species in the tree category.
Many developers plant invasive species, tho, because they're so bulletproof they can survive the compacted subsoil that's in place once they're done putting the home in. Then people see that's what everyone else has in their yards and want to follow suit so they plant them too, so the nurseries see they sell well and stock ever more of them. It goes on and on.
