The great 'just prune the top' misunderstanding I keep seeing in my town
Okay, so I'm in a small city park a lot (Springfield, if you're curious) and I keep hearing homeowners tell each other to 'just take a bit off the top' of their big oaks to let more light in. They think it's a simple haircut. I saw a guy last Tuesday with a brand new pole saw, about to just flat-top a beautiful pin oak because his grass was patchy. I had to walk over and explain that topping is basically a death sentence, creating weak, fast-growing water sprouts that split later. It doesn't fix the light issue, it just makes a dangerous, ugly tree. I showed him how to identify a few interior crossing branches we could actually thin out instead. How do we get this 'top it' idea out of people's heads for good? Is it just bad advice from old gardening books?
