this is my second year on hops. Three of my 4 hop plants have already reached 12 feet high with 3-4 vines each except my williamette which is only about 5 feet tall on the 3 vines that I let grow. My question is that the ones that have reached my horizontal wire are seeking somewhere else to go. Should I trim them back thus causing the rest of the vine to kinda fill out or thicken up?
