I have never harvested any cones from my plants. Last year they produced ten cones... combined. This year will be a bounty. My Centennials look very close to ready and my Cascades look maybe a week behind them. My question is that my bines are still forming new cones as well as have many nearly ripe and pickable cones. Do people harvest all their hops at the same time or just pick the ripe cones (ones that are browning at the tips) as you go?
