Whats going on with these cherry trees?
I planted 4 cherries this spring and they all seem to be doing great but I have noticed some "changes" the other day.
The first 3 pics show one tree that has this gash and seem to have a little sap coming from it. I painted them all with paint and I do not remember that being there at all.
This one is from a different tree and the graft looks like it got chewed on by some bug. What could it be?
This is from a 3rd tree that don't seem to have a problem except for couple of leaves that look like that. Didn't see anything alike in the internet. Signs of problems?
I am a newbie with all of this; so should I be worried about any of these? I understand borer can be a problem so I'm trying to catch problems as soon as possible. Should I apply some imidacloprid? I would prefer to stay away from chemicals but I rather keep them alive. Should I paint them back in those spots?
