I have six hop plants growing in pots right now. Some seem to be doing better than others, but my Chinook has the best looking and tallest bine on is so far, about 6'. The problem is that this is the only shoot on the plant. Will is send more shoots up? I am worried about the one shoot breaking or dieing thus killing my plants' roots underground. Anyone have a similar experience or advice? This is my first attempt at growing hops, and the plants are all between 1-6 ft tall, and I plan to put them in the ground this week.
