These are two Celtis I have. I think that’s what they are I’m not sure see here
This first one was repotted this Spring and was placed in the poly tunnel. I didn’t defoliate as I want to thicken the branches and chop back.
The other one wasn’t repotted and had been outside on a bench. For some reason this one got mildew and I had to defoliate. I thought being outside with good air circulation would have been a less likely spot to get mildew, but what do I know.
This is it a month after defoliation.
