Acorns are the standing complaint — large, round, shallow-capped, dropped in quantity in a mast year every two to five years, hard on mower decks, slippery on drives and steps, and a squirrel magnet. Add long yellow-green catkins in May that clog gutters and stick to car paint, and a heavy late-season drop of tough, slow-rotting leaves.
60 to 75 ft tall and often just as wide in the open, with roughly 200 years a normal lifespan and 300-plus possible — a mature red oak over a house is a serious crane or technical rigging removal at the top of the cost bracket. It is also fast for an oak, so a tree planted at a 1990s subdivision build is already large enough to matter.
