Pistachio pollination biology and artificial pollination

Phoebe sits down with Elizabeth Fichtner to discuss the biology of pistachio bloom, how it impacts orchard design, and why picking the correct male pollinator is so important. She also goes over the research on artificial pollination of pistachio and why it may only be useful in very specific circumstances. In this episode, Elizabeth mentions that dust can cause parthenocarpy in pistachios; we posted an episode on this a few years ago.
