I feel just sick about this. I had some very old pecan trees right on the street. They were dirty, sticky, brittle and dropped leaves all over the neighborhood. In a fit of insanity, I had them cut to the ground. People driving by are in absolute shock now. I did a really stupid thing. My question is now, will they grow back from the stump? If so, do you leave multiple shoots until they are a bush and then eliminate all but one?
