Q: Is it common for a river birch to lose 1/3 of its leaves in July?

Q: My 13-year old river birch loses 1/3 of its leaves every July. The leaves turn yellow and drop off. Every spring the tree looks healthy again. Is this common for this tree?

A: River birch is a common appointment in landscapes across America. It is a riparian tree, thus their need for acidic soils. “Yellows” often are an outcome of being planted in alkaline, compacted soils. This is often a sign of decline and potential death. Is the “1/3 yellow and fall off” on one side of the tree? This may point to localized root anomalies. You should call an ISA Certified Arborist for an inspection and then get a soil test.
