Update: Picked all hops. Was lucky as I got it off just as the first few drops of rain started to fall... I think all the rain would have washed off a few points of AA%
Got about 800g wet off both POR and Cluster, and about 1kg wet of Chinook. All are vac-packed and frozen wet.
I saw this this morning on the Grow Hops Yahoo Group and thought I'd share. It follows suit with info from Ralph Olson not to trim bines back at the end of the season until they have drawn all of the sap back into the rhizome. I wouls even go so far as to say that you could even give it a good last hit of fertiliser after harvesting to pump a bit more out of the foliage and root system.

Nitrogen and potassium are both very mobile within the plant regardless of shoot age. If you graph the nitrogen uptake with plant biomass accumulation you'll find that the slope starts shallow in April/May steepens during june and really takes off, almost vertical during mid June and July. It tapers off again in late July and August. Potassium follows a similar slope but not as steep. Granted, N is required for general biomass development, but much of the compounds in the flower development are heavily N dependent. Too much N after flower development will result in vegetative bolting of the axial buds within the cone...looks like another shoot growing out of the flower. Water uptake follows a very similar slope.
Think about it from the plant's point-of-view...it doesn't stop photosynthesizing after cone set. Studies have shown that bines allowed to stand instead of being removed for harvest can produce up to 30% more yield and alpha the following season. 6-8 more weeks of carbohydrate partitioning and storage for spring...
