The pollen is released when the pods flop over and open. They look like tiny yellow-green flowers.

Cutting them off would prevent them releasing pollen but it's hard to get them all and really not worth the risk.

You can also spray them with water, neem, or wilt-pruf to make the pollen non-viable BUT THIS IS NOT 100% GUARANTEED TO WORK.

So please everyone just kill your males and save the other growers in your town a big headache. Please?
