Work plenty of organic matter into the soil to improve water retention. Soil fertility is also important. To increase the sweetness of your melons, hold off watering just before harvesting to give the melons time to develop more flavor. If your vine crops fail to bear fruit, you may have to play the role of an insect. Note that vine crops have both male and female flowers on the same plant.
Female flowers have a miniature fruit behind the flower petals while the male simply sits on a stem.
To transfer the pollen, take the male flower from the plant and remove the petals. Dab the pollen found on the male's center structure onto the female parts in the center of the female flower. They will no more crossbreed than do cats with dogs. There are two flower shows today. The University of Nevada, Las Vegas Arboretum is having a plant sale from 9 a.m. until supplies are gone Saturday at the tennis courts.
