Post oak was used for posts in my area up until about the 1960's. Made good posts but were lots of work to get. some split good but a lot of it was hard to split. Would last 20-25 years here and the only rot would be right at the surface of the ground. some people would swap ends with them and get another 20-25 years. Creosote posts and metal posts mainly did away with them here, as there was not as much work. miles
