(can't find one that long), which is why I mention feeling for moisture at the one drain hole to determine when I need to water. But, no, I don't know that I have root damage, that's absolutely true.. I thought it possible when I searched for info on wilted leaves and yellow spots for this particular plant. Two years ago, what I read & concluded (was that I was overwatering)--that was undoubtedly true, but I've been quite cautious since then, but perhaps too much so. The continued tendency towards wilted leaves bugs me (and some blogs have suggested that means poor aeration). Of course, it has had to live through the cold wintery drafts near the window, but I've kept the heat pretty minimal so it doesn't suffer from blowing hot air "vent" damage but try to not let it get colder than about 59 degrees
I'll link a few of the articles on H2O2 treatments (though I agree at that dilute concentration it is not likely to harm, but perhaps would not be helpful either....) Maybe I'm just obsessing since warm weather did tend to help it thrive last summer after all the winter damage....
