I haven’t seen or heard anything about the annual Gingko tree spraying to reduce fruit on female trees. Looks now like it’s too late as the trees have already pollinated. Do you know why the city did not spray this year?”
Ed. Note: Last year at the end of April DDOT issues a press release saying they would spray the trees “to prevent the notoriously unpleasant odor of female ginkgo fruit”. No such press release was issued this year. However on the DDOT Gingko tree page they say “Today, Urban Forestry Administration sprays these trees with a mild pesticide each spring to halt fruit development.”
A call to DDOT reveals that they don’t actually spray until the trees start to bud before the fruit is produced – and when budding starts they will again spray this year.
