They should feel papery dry on the outside, but still bounce back when you squeeze them. Another good test is a clockwise twist of a cone should have them fall apart pretty easily. Shouldn't be brown yet, so if you see the tips starting to turn it's not too late, but it might be a day later.
Another tip I heard on a podcast this year is to leave the bottom 4 feet of the bines attached to the ground, give them a couple of weeks and bury them again in a circle around the mound and in the spring, they will have turned into rhizomes, with a node at each leaf node. In 4 feet you should get about a dozen new rhizomes.
My Fuggle came in today and is in a drying box we're trying out this year.
It was 1.4 Kg Wet, so should end up being about 12-14 ounces dried.
My 2nd Galena came in yesterday, I'll be weighing them dry when I get home tonight, I'm guessing it'll be about 6 ounces or so dry.
I think we're going to pull down the Willamette tomorrow, I'm guessing given the Fuggle success it'll be at least half again over the Fuggle.
