that are starting to brown and fall off at a higher rate than normal. I suspect a beetle infestation.
We apologize but we would recommended getting the issue diagnosed before we are able to recommend what product would work to correct it. Please contact a local master gardener or landscape company for advice on identifying the issue. Once they are able to help you ID it, we would be able to better make a recommendation.
