Had to hire a tree service to cut off a couple very large branches, as they were leaning precariously over the house and garage. They cut them off like this, and left it at that. My question is this: While getting estimates for the job, one tree cutter who claimed to have been in the business for decades, said, "You'll need to seal the cuts or this tree will die". The cutter who did the job, didn't mention sealing at all. At any rate, I checked and all over Google, it says, "Let the tree naturally heal, if you put tree sealer on large cuts it will trap moisture and kill the tree". So which is it..... don't seal the cuts, and the tree dies, or seal the cuts, and the tree dies? Anyone??
