we just bought 5 bradford pear trees and plan on buying 4 more but anyway i was wondering how fast do they grow... they are about 4 and a half foot right now...o, we get to your point, they probably are only good for maybe 35, 40, 45 years out here if maintained decently. Hey! Out here, that is a great ornamental tree choice. And, fwiw, the old trees I planted were B pears, I have a Cleveland pear at my new house, so there have been plenty of chancs for them to cross here.
