I live under an ancient white oak that seems very strong, but noticed something interesting I wanted to ask about. I'm starting to have to sweep the terrace more as leaves fall, but noticed that there are lots of what appear to be flowers falling. I can't remember ever seeing flowers this time of year. Is this something that happens? There was normal flowering last spring, but I've not seen many acorns this year, which I know can be normal some years.... David Larchmont, NY
