I guess I assumed until recently that most people know how to sex their papaya plants but I was wrong. People will nurture a male papaya for over a year and wonder why they never get any fruit....only the females set fruit. Thankfully they are very easy to tell apart. I cut down my males as soon as I know they are as there is no apparent need of their pollen by female plants. Just remember...the male blooms are long, like a penis!
