This is my 4th year of growing hops. I plant Cascade, Centennial and Williamette here in New England. In years past the Centennial have been the most robust followed by the Cascade with the Williamette the less of the three. This year both the Centennial and the Cascade did very poorly. They didn't grow nearly as robust as in years past, had much less yield, much smaller cones and started to lose color fading towards yellowish with the cones turning to a very light green or almost white. That is the ones that didn't start to turn brown. Granted, it has been a cooler year this year around here with more rain so I'm wondering if that might've contributed to it all. Then again I've never fertilized them at all either but it was a pretty drastic change from years past. Anyone shed any light on this for me? Thanks.
