They will do well in Iowa, if you baby them.
I have 400-500 that I am in the process of babying (weed mats, mulch, tubes on 100, cages on 200, full sun, etc). Also have another 750-1000 that I care a little less about. Just about done for now. By next spring I hope to be all done with them and then limit myself to 20-30 every year after that and do more fishing. I'm ready to pull the trigger on a very nice walleye boat, side imaging, down imaging, spot lock or any other fancy crap you can put on it. I gotta get it deck out with expensive electronics so I can spend most of the time taking the kids tubing. LOL.
Babying trees is the only way to go if you ask me. Plants really respond if you care for them.
