My pumpkin plants are doing great. One, however, is vining all over the place. I know that I can tip off the ends which will cease growth and then will not produce any more pumpkins than have already blossomed. However, I am wondering if it will hurt either the pumpkin plant or my other plants in the garden if I direct the vines to weave in rows among potatoes and tomatoes? Or is pinching the ends recommended for other reasons? I have some blossoms near the main vine, but none on the branching out vines yet. Thanks!
