For what it is worth, I do what Leo does. I'll knock out as much old mix as I can, but mostly just pot up. The plants seem to figure it out pretty well.
Soap and Water!?! The knot is the old growth, I'd just knock out any bad [rrotted] media and put in a biggfer pot w/ new stuff poke into and aroung the root mass.
You're a day late and a dollar short my friend. Plants have all been re-potted. You too, are totally forgiven this time for being so late to the re-potting party. It's the holidays and I'm feeling charitable.
No way! Not unless I can wear blind folds and re-pot at the same time. My lust list has grown exponentially from hanging out here. You people have totally corrupted me. I don't want to look at anything I don't already have that I might like and I'm afraid you've probably got lots that I would like. See, that's the problem... I'm starting to like so many.
