A homeowner in Fresno asked if I could "just top" a 60 foot redwood and I still think about it
Was doing a removal estimate on a redwood last spring, about 60 feet, decent lean toward the house. Homeowner walks out, looks up, and asks if I can just top it at 20 feet so it stays "manageable." I explained that topping a conifer like that usually sends out weak shoots and ruins the shape for good. He nods the whole time, then says his last guy did it to his pine and it "looked fine for a year." I asked what happened after that year. He got real quiet and said a big limb came down on his shed. We ended up doing the full removal, and he told me his neighbor across the street is now asking about topping her oak. What do you all keep in your back pocket for that conversation when they bring up the last guy who did it?
Tbh the pine story he told is pretty weak proof on its own since one limb could come down for lots of reasons, not just the topping. A year of looking fine is not much of a test either, and trees do all kinds of things before you can tell if a cut hurt them. Ask her if she's cool with the risk, since it's her oak and her call at the end of the day.
