You need to be careful about using a weedkiller there medavidcook. Glyphosate is only weedkiller I would use.....it won't harm your apple tree; I use glyphosate around fruit trees in an orchard. However ??ou will have to wait until next spring to use it.
You could cover with a membrane to exclude light etc but glyphosate is best. Can you dig over the grass away from tree? If you want to prepare a planting bed over winter this is an option
Sure you cannot remove this tree? I have removed pretty hefty trees and shrubs and nothing has "stumped". ( get it! Good eh? ) me yet. A nice clear plot is what you really want after all
