This July and August, the WDBJ7 Weather Center has received numerous photos of green acorns covering the ground across the region. The acorns are green, which indicate the trees are dropping them prematurely. Mature acorns are typically tan and often fall during the months of September and October. While an early acorn drop doesn't always indicate a serious problem with the trees, it can mean they are struggling.
All of the information in this article for germinating and growing oak trees is specifically referring to this species but can be applied to the other species as well. The acorns of White oak are produced in one growing season, unlike the acorns from Red oaks (Quercus rubra) whose acorns develop over a two year period. Oak flowers are wind pollinated and are dependant on favorable weather conditions for successful pollination.
