OK the pond is almost clean. I am dividing and re potting about 150 new Lily's (my best guess) I have cleaned them up with water and a scrub brush and divide them into categories for planting; small eyes-big eyes-multiple eyes-eyes on rhizomes-large buds and small buds. Yes I'm anal, goes without saying. I call the end of the rhizome that was the leaves and blooms the bud, if it has another term please let me know. Some of the buds have a white film, it wont scrub off and I am concerned about it contaminating the other plants and killing the ones its on. Is there some kind of dunk or soak that I should do prior to re potting to be sure they are disease free. This pond that they came out of was a mess over 200 man hours to clean it up, probably plenty of funky pathogens.
