@Lynn, because of the heat that squash needs more water. To get the squash to produce, pick one male flower and use the stamen to tickle the other flowers. This will trick the vine to feel as if the bees are around. Do not wet the leaves as this help the spores of the fungus to take over. Build up the soil around the root to form like a mini pond to retain the water. My Guyanese neighbor grows it on his cherry tree and the fruit is about 9 to 10 feet . Love it with black tiger shrimp and fried Banga Mary on the side.
