Well DP, I am going to disagree with you. I think the sooner she gets out of the troublesome MG soil she will do much better.

Yes do the knife thing around the edges, support the soil around the stem and turn upside down, might even have to tap on the pot to get it all to release. A little root damage may occur, but I think not. Just sort of let the root ball crumble in your hands and then repot into the OF or whatever.

Maybe do the worst looking plant and see how it does first? These puppies are tough, you have a better chance of getting an ulcer than killing them you worry-wart you. LOL.

Have a good day
