As a follow up, I'm reading a brochure that came with the Rhizome. It mentions that "this is when the flower is receptive to pollen and if males are present, wind-borne pollen will fertilize the female flower and result in a seeded female hop cone".
Does this mean you have to have a male plant around in order to get hop cones to grow?
No. You don't want males around. The females will produce cones regardless. But if a male is present, the cones will get pollinated and produce seeds. You don't want seeds. But good question.
Seeds are looked down upon, but I have seen them with frequency in British hops, less often in American hops and once in some Hallertau Mittelfrueh(!).
The growth cycle is rapid in the spring, but not the fall. At the summer solstice the small burrs start to form, then the cones come from those. Where I live the cones are ready to harvest from mid August to mid September depending on the growing year and variety. I harvest of the bine, but commercial growers cut the bines down then for harvest. I cut the bine down in the fall, leaving about 2 feet above the ground.
Edit - if you are in FL you will have a much earlier harvest than I do.
