pumpkin vine color
Hello! First timer poster here with a quick question about pumpkin vine color.
The main vine of my pumpkins has become a very dark green color. I'm not sure if this is good or bad, however I have noticed some vertical splits (run along the vine) in some areas, and it looks like the vines are becoming tougher. Can anyone shed some light on this? I am assuming they shouldn't be getting so dark. (please see pic)
Other information: I have two plants growing on trellises and planted directly into the ground, and have seen this happen to both of them.
