Nuts in thick four-part husks drop hard from 60 ft or more through September and October — they sting on a driveway, roll underfoot, and jam mower decks. The second one catches people off guard: long curling bark plates shed off the trunk year-round and pile at the base, and homeowners routinely mistake that shedding for proof the tree is dying.
Roughly 70 to 90 ft tall with a 50 to 70 ft spread and a realistic lifespan of 200 to 300 years, so a sound one is a keep-it tree rather than a remove-it tree. When one does come down, dense heavy wood plus a wide spread pushes it into the upper cost bracket, and the debris and chip volume runs high for the trunk diameter.
