Is it ok to trim a pumpkin vine or will it somehow ruin it?

We planted a few up on the hill in our backyard and they are growing like wildfire. We want to trim them but don't want to damage the pumpkins or somehow risk the health of the vine....maybe it is a silly question, but they were planted for my five year old and she is sooo excited. Last year the vines started out great and then suddenly met an untimely death...we are trying to do all we can NOT to kill them.....Thanks

They say to take all of the flowers off a vine except one if you are trying to grow a very large one. Our vines died because we got the squash borer beetle. Every year they ruin our vines and are ferocious eaters of the growing pumpkins.They are flat and gray. Go to a nursery and ask about powders (Sevin dust) etc. to try to keep them away. Water ,water ,water also. Good Luck!!!
Reply:There is not much you can do to hurt a pumpkin vine that wants to grow!
Reply:leave it ALONE! best thing to do is if they are creeping out into places you dont want them to go is to pick them up carefully and point them in a direction you want them to go ! otherwise dont prune dont remove old flowers, just let nature take its course and you will end up with excellent sized punkins for halloween !
Reply:You should nip them out - take off the growing point after you have 4 or 5 good fruits set (fruits not flowers) you want all the energy going into the tasty bits, not the leaves.



Then if the ripening fruits are obscured by leaves, take them off too. Make sure they are not sitting in a wet patch and that they are getting loads of sunshine - and food.



They are greedy little buggers pumpkins so give them a good feed - I usually use liquid seaweed for all my produce, but with cucurbits I let them have some big name brands - with the big amounts of fertilizer.



Try not to get the leaves too wet - then cross your fingers and hope for sunshine!
