Repotting a tight root mass like that can be tedius you certainly don't want to rush or you will break roots, but I work away at it patiently. I find it therapeutic. And I keep telling myself how much happier my little plantie will be now that its roots can breathe! A cold beer or a glass of wine is always involved! Just as well I don't usually repot in the morning!
Good luck to the lil' critter!
