My 3d year Cascade appears to be a victim of Verticillium wilt. Looked up hop diseases online, and this appears to be the culprit.
I've not had the best luck growing hops at this house; last year's Cent and Magnum didn't make it, despite adequate fertilizing/watering.
If there's a bright side, it's that tomorrow is our trash pickup day, so the Cascade plant will get excavated and binned today after work.
Feck.
