Phenology: Oak pollen almost done
Oak flowering in central Kentucky is almost done for the year. This is good news for allergy sufferers, here in the pollen capital of the US. Oak catkins (male flowers, pictured on the right is scarlet oak) are dropping from the trees, and pollen counts are declining. This has been a good year for oak flowers, with no late-season frosts. Most of the wind-pollinated trees flower early (oak, elm, hackberry, hickory) before or at the time of first leaf flush. For the remainder of the season, insect-pollinated trees will continue flowering. These do not pose problems for people with allergies, since they do not release large amounts of pollen. However, grass pollens will begin to pick up shortly.
