Brent's place is very dry, not much humidity (except when it is raining). I think that if you can get Mughos into a good soil mix, protect them in the summer from the humid heat of the hottest part of the day, they may make it. But there is a point where there aren't enough cool days (perhaps nights may be more important) for them to thrive. I had a few JWP, grafted and on their own roots in Northwest Arkansas for years, kept them under 30% shade in the summer and protected them under plastic in the winter- they did great. The Mughos, just never did anything, but that may just be me. I can't imagine Mops making it in SC or GA, but I would love to be proven wrong- not with one year trees, but with trees that have made it at least 5 years and preferably 10 to really know.
Steven, sorry for your losses, but both should adapt fine to Indiana, might be the trauma of the transition, sorry.
