Question From: Pleasant Hill, California, United States
Q: In the fall the leaves of the Russian Birch turn yellow, then brown but many do not fall. Is this a problem?
I don't know the answer to this one. My guess is it is weather related. I suggest you visit the arboretum near you and/or Sloat Garden center for more accurate advice about weather related issues with plants in your area. Best And Happy Yardening, Nancy
