Elaine - Thank you for your advice. Yup, my Brug's trunk rot looks like yours. I've never had that happen on any plants. There is no new growth coming from the ground, which is why I am worried. I love this small tree. It has perfect single pink blooms and it is just my favorite brug. I wonder if I should take some stem cuttings to root (just in case). I checked all my other brugs and I am not seeing this issue. Also, I do treat my container brugs with Bayer 3 in 1 due to moth caterpillars and various diseases. I will try treating them all again. I noticed the leaves are getting chewed up again on many of them so that tells me the Bayer has worn off. It is the only plant species that I treat with a systematic. I don't treat the rest of my plants because the butterflies, bees, and hummers use the blooms. I did see bees using the Brug blooms but after treating them, I think it may have killed them as I stopped seeing bees. Sad to say, but I don't know what else to do. I hate using pesticides for that reason. I tried to treat it early on during Winter while the bees were dormant, but the systematic lasts a long time.
