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.
The best time to collect acorns, either off the tree or from the ground, is when they begin falling - just that simple. Prime picking is late September through the first week in November, depending on oak tree species and location within the United States.
