Need to know If we can do a thick Mulch 12" to 14" around one side of the tree. Trunk is about 18" to 20" round. Keeping it 12" from the trunk to prevent rotting. I see concrete slabs and driveways covering 1/2 the drip edge all the time and they are still alive. Point being, we want to cover up what will not grow grass and only weeds and thick mulch stops weeds. It is already in place and it looks great but do not want to kill off the tree.
