Central Texas allergy sufferers are having a tough time because oak trees have been producing significantly more pollen this spring, said horticulturists serving the area.
Daphne Richards, horticulturist, Travis County, said a major reason oak trees in the region have been producing more pollen goes back to last fall.
“Last fall we had a lot of rain followed by a nice long period of winter cold, which the oaks haven’t had in many years,” she said. “These factors combined with the additional rains we’ve had recently created optimal flowering conditions for oaks trees in this region. So a lot of people in Central Texas have been seeing an abundance of yellow pollen and live oak catkins on their lawns and streets, and covering their cars.”
Catkins are the worm-shaped male pollen tassels that fall and collect around oak trees after pollination.
Richards said fall rains just before the oak trees would normally go dormant, then subsequent rains this spring, provided the oaks an extra pollination punch.
