Holly tree leaf discoloration

Asked April 27, 2019, 9:05 PM EDT

Many of the green leaves on my holly and my neighbor's, both well established trees, are turning yellow, with small pencil-point-sized black spots. Would that be fungus? Or? And what if anything can we do? We live in Catonsville.

Baltimore County Maryland

Holly trees normally drop some old leaves this time of year. The leaves first turn yellow and often become spotted with various fungal spots as they weaken, preparing to drop. It is all normal. This explains further: http://extension.umd.edu/hgic/topics/normal-leaf-shedding

Even though hollies are evergreen, they still drop old leaves. If they put out a lot of leaves in a particular year, then a few years later when that year's leaves are old, the tree will seem to be dropping more leaves than usual.
