Albizia Julibrissin Leaf Yellowing
My Albizia Julibrissin (Mimosa Tree) is about 5 years old and has grown vigorously in my CT yard. Over the past 2 summers, I have noticed leaf yellowing on the outer leaves. I had very little flowering this summer relative to years past. Could someone please identify was is affecting this tree? Are there any remedies? Thanks very much.
