It Grows! This is year 3 and we're off to a good start. Should I trim it back yet or let it grow for a bit? I read somewhere that you don't want to let the first shoots climb up the rope.
I live in Nor Cal...It's been cooler than usual summers. I wouldn't hesitate to cut those back. Keep one or two runners...You might see more develope later.
Also be sure to not neglect your phosphourous. Nitrogen is important but phosphours is also highly important.
You can use hop leaves like you would grape leaves for making stuffed greek appetizers
