Summary: Prune tree fruit set is tricky business! Good fruit set occurs under a relatively narrow band of conditions and then requires thinning if good fruit size will be achieved. Franz Niederholzer (UCCE Colusa & Sutter-Yuba Counties) and I discuss what UC research has learned about bloom conditions and what growers can do to manage fruit set. Thanks to the Pistachio Board of California and Almond Board of California for their generous financial support. Music by Muriel Gordon.
