Rosemary Alexander and Tim Boebel are the featured speakers at the Rochester Civic Garden Center's Spring Symposium, March 3. All of the details are here. The RCGC always does a very nice job with these events, so if you're on the fence, we recommend you go and check it out. It's always inspiring. Of special note to area gardeners: Boebel has some radical ideas about hydrangeas, getting them through the winter and making them bloom. It's exciting because he's still experimenting, testing theories and modifying techniques.
