You need to support them enough that their weight doesn’t strain or kink the vines. I like using onion and citrus nylon net bags — use as bags or cut open and make hammocks. When placed inside a bag, the fruits can sometimes grow too big so inspect often and cut open the bag as necessary before they are so tightly wedged it becomes impossible to cut the bag. This is why nylon stockings and tights are popular since they would stretch, but the stretchiness sometimes can make them sag too much as well.
