Hi Y'all, I'm working at getting the fenceline around our place cleaned out to build fence. I've go a few nice size trees, about 6" to 10" in Diameter, right in the fenceline. Can I get away with just cutting them off at 6' tall, putting Round-Up on top of the tall stump, and, then using that as a permanent fence-post? A couple of these trees are Honey-locust, ash, tulip poplar, cherry, asf. It'd save me a lot of work, cutting the tree, just to make a post out of it. At my age you want to save all the work you can. Thanks Y'all.
