A big thanks to everyone who has responded so far, and in advance to any possible further advice.

I have learned a lot from this thread, especially from looking up some of the words in rhizome's replies. It seems like nobody has seen anything quite like it before, and can't give me specifics. (Come to think of it, I didn't see anything excatly like it in either of the problem charts i linked above.) Please do not worry in the least about this, since you have given me many good ideas and pieces of advice, as well as pieces of the puzzle, which I will take to heart. I appreciate it very much.

I will look into a 'zyme product. To aid in my product search, does "zyme" mean "enzyme"? Seems so. If so, come on rhizome, it's only one more key stroke to spell the whole word. (I jest.) I looked up zyme in an encyclopedia, and it said it was an obsolete medical term formerly applied to the class of acute infectious maladies. Zymotic disease - Wikipedia, the free encyclopedia

I will zyme, anti-wilt, repot, flush, quaranteen, ventilate, not necessarily in that order. I would prefer not to go to a bigger container, since that one is fairly big already. Do you think it would hurt much to cut off some root if it appears to need that? I know this is how you bonsai, but those bonsai plants are presumed to be healthy, and I don't want to overstress the plant to the point of possible nonreturn.

OH, I gotta ask about the tabacco smoking. Does that inhibit pests, viruses, and/or diseases, or promote them? In general why did you ask that question. I know several people swear by using tabacco juice to repell pests.

Unless pride goeth before a fall, I am proud to have introduced something to this board that people have not heard of before.
