Hi all. So I was having a look at some of my maples yesterday and noticed 2 in particular looking rather unhappy. My Nicholsonii looks like it has suffered a pretty hard frost as all the buds which were swollen and about to emerge are now droopy and falling off. I'm hoping they'll drop off and it'll have enough energy to push some new buds. I'll take a picture of that one later. The main concern I have is for my Elegans. It appears it could be frost damage that has expanded the cambium layer or something. Or perhaps is a bacterial infection that's spreading upwards. I only looked at it a couple of weeks back and didn't notice it, so a frost would make sense for the extent of the damage to show so fast. The buds all look fine though.
