The Orchard Mason Bee Book, Brian Griffin bees Our double screen uses 3/8This primer has become a definitive text on keeping Mason Bees. The Author, Brian Griffin, was a pioneer on the systematic management of mason bees for pollination. It is a treat to read this classic by a man speaking from real experience.
