So, I'm in the 2nd year of my Himrod. The 1st year I left only the main trunk and now it has 5 shoots from the main trunk, so far about 20-25" each. When I'm supposed to cut them off and how many I should leave. I have 2 horizontal steel wires so is it the time to train them on both or just the lower one. Do I cut them at the end of the year, fall or now?
