Dan O ,We bought our property in 65 the large oaks bear acorns ,other trees in or near our yard have never had a nut on them in over 37 yrs..Maybe trees you buy at a nursery grow faster,I dont know but the ones in the wild grow awfully slow.Now pin oaks grow fast and bear acorns when the trees are small.Thats what( West VA Paper and Pulp ) plants.I think the pin oak is a type of white oak..
