I have a male hop plant because I found them in the wild. It is already too late this year and the hop cones on the females have seeds. Is it as simple as just removing the male rhizomes? I know this is very similar to growing weed. Do I have to worry about the seeds from the cones being dropped and being planted next year?
Yes, you dig up the male plant and get rid of it. The seeds I’m not sure about, you might want to harvest the cones before they open and drop the seeds, just to be on the safe side.
