Answer: If your gourd plants haven't set any fruit yet, your chances of harvesting gourds at the end of the season aren't very good. Gourds grow and mature only when provided with a long, warm growing season. Most varieties, especially the giant dippers, need over 120 days of hot weather in order to mature.
You may have to give up on your plants and try again next year. Be sure to plant them in a spot that gets all day sunshine. You can prolong the season and help radiate heat to the plants by covering the growing area with black plastic. If you start the seeds indoors in March, you can set transplants out as soon as the weather warms in the spring. All of these strategies will encourage early fruit set.
Better luck next time!
