We have a mature Japanese maple. Unfortunately, the 'gardener' tried to prune it and has cut almost all the way through the main trunk at the top. Will the tree still be able to get nutrients to the top if we seal the cut?

Tree wound sealants are no longer recommended. In fact, sealants wound dressings for trees may actually interfere with its natural healing ability. Most trees will eventually produce tough calluses that help prevent decay or disease. Your tree is probably going to be fine. I would give it some time before trying anything drastic, as long as the tree is not showing any signs of problems. If this is the case, you may want to seek out some professional advice.
