It's hard to clean or paint behind latticework, so make a hinged trellis that swings open. Fasten a strip of 3/4-by-1-inch wood to the wall about one and a half feet from the ground; screw hinge plates to the underside of the strip and the bottom of the trellis. Attach another wooden strip to the wall at the level of the trellis's top crossbar. Screw metal eyes into the strip's ends and metal hooks into the ends of the crosspiece so the trellis can be unhooked and pulled away.
