Was out checking a client's elm tree yesterday and spotted random branches with yellow leaves. No visible bugs or damage on the bark, which is weird. The soil seems ok, but idk if that's the issue. Anyone else run into this? What's the next step for figuring it out?
He grabbed garden shears for branches as thick as my wrist, making ragged cuts that won't heal right. I had to explain why proper pruning saws are needed for tree health. Family help is nice, but without the right skills, it does more harm than good. Now I politely but firmly handle all tree care myself.
