Canby Oak Bleeding Sap
I planted this 15 gal Canby Oak early this spring and it started off just fine, putting on about a foot of new growth.
I just noticed that it's bleeding a good amount of sap from a small opening where a branch was cut off. It's only coming from this one opening.
Anyone have any ideas on what's causing it and how to stop it? I'm afraid it's an invitation for pests as it stands.
