Check the soil nutrients. It sounds like you might have too much nitrogen, which can result in lots of leaves and vines, but discourages fruiting. If you think that this might be the case, then choose a fertilizer high in phosphorus and low in nitrogen. (To be sure, test the soil to assess what nutrients your plants will need.) Apply fertilizer at time of planting and then when the first fruit sets; after that, side dress once every 7 to 10 days. Good luck!
