This spring I have noticed that some (not all) of my holly trees seem to be struggling. They are not blossoming like the others and a number of leaves on them are yellowish with little raised black spots. I have read through multiple articles and there is nothing that it seems to match perfectly. Any advice would be greatly appreciated. Thank you.
What’s Ailing My Holly Bushes?
The yellowing leaves with black spots should be on the leaves closest to the trunk. This is normal, and the tree is getting ready to shed them to be replaced with new growth.
As to the non-blooming, maybe this is just the year they don't want to bloom?
