I have been thinking of eating my squash blossoms since they aren't producing any fruit anyways. My hunch is rabbits eat the tasty baby squashes as soon as they form. We have plenty of bees for pollination.
Do you have a lot of rabbits this year? We have more than I have ever seen in my life, and that appears to be true for folks throughout the north shore. I love watching the bunnies in my yard, but I'll admit I loved them more before they started eating my hostas.
