I have a bisexual Zeus. Its name is Pat.
I snip the males out...as there are not very many.
I have also had an all male Crystal. That bastid never did get any feminine parts, so I let him have it with some Roundup.
Neither of these plants were stressed. Both came from Freshops. It happens.
What is a bit scary, is that I have hops in the garden coming up from seed; I also have one plant that appeared over 50m away from any other plant that I swear seems to be a cross between the male Crystal and a Chinook.
Hops are wicked prolific and have the genetic potential to take care of business themselves.
