We have a raised bed veggie garden and my pie pumpkin is thriving (good), but overwhelming the cantaloupe and watermelon (bad?). The raised bed is surrounded by 2" landscape rocks. Is it a good or bad idea to gently redirect the pumpkin vine out onto the rocks? There is one baseball size pumpkin growing - thought I would redirect the vine after that point on the vine. We're having trouble with pollination so I've been trying to do that manually. Would it facilitate bee pollination if there were more access or do the bees go under a crowded area of leaves?
