Brenda--After reading some old botany journal entries on the web. It does state the male tree will throw it's pollen all at once. It will look like puffs of smoke. I wonder if that is a phenomenon that happens when the female tree is close. I have never seen any of the male paper mulberry's pollen explode, and I work around them all the time. Next year I will be on the hunt fot exploding pollen! Cool! May you be surrounded by peace!
