The Dahlia Society of California meets the second Tuesday of every month, except January. We learn what to do (and what not to do) with our tubers and dahlias from the experts in our society. Members can attend in person or on Zoom.
September Program:
Bring your blooms for a MINI-SHOW!
Got plants in peak bloom and want to show off what you’re growing? Bring them to the September meeting.
Fill out the entry cards just like you would at our Annual Show (find Show forms and info here).
This is also a great learning opportunity for those who have never entered the show.
More meeting details announced at the beginning of the month.
