Like many people my bines took off fast in March due to the unseasonably warm weather, they were doing great and then April really cooled down and they just stopped growing. They were at about 8 feet and really haven't grown at all in the last month or so, but they are starting to sprout lateral vines, just not growing any longer.
There are new bines coming out of the ground and growing pretty fast. Should I just cut back the first bines and let the new ones grow? I'm wondering if the cool weather messed up the first bines and I'm scared they won't grow any longer.
What does everyone think? I did trim back one of the old ones about 2 weeks ago because it got snapped and let a new one take it's place, and it's almost caught up to the older ones already.
