a. Move the bees elsewhere in the yard. But is there any point in our yard that is far enough? And is it too late for these particular bees?
b. Cut down the buckeye.
c. Give up on the bees.
If it could work, "a"would obviously be my first choice. Until two days ago, I loved our buckeye tree. But if "a" is impossible, I am currently leaning towards "b." It feels like a crime to cut down a native buckeye, plus it will be expensive. But the poor bees.
