I have 1st year hops in homer buckets and the two to the left are already approaching 10'. I am very excited about this but also a bit concerned . I know that I can let out rope as they reach the top, but they will keep growing? I do not really want them to sag on the ground and I do not think trailing them horizontally will work for my set up ( although it could...possibly) I cannot really raise the poles any higher as there are power lines going out of the back of the house. Do they grow until the end of the season or do they stop when they start to create the cones? Is it wise to trim off the top?
