Bottle gourd female buds all dropping after blooming, and the suggestion to hand pollinate is not possible because it has a high
trellis. And somebody suggested the dropping is because of fruit fly. Even a fruit trap didn't work. So, solution?
Hand pollination is not possible and on suggestion, I applied boron and used fruit fly traps without success. What should be done to arrest fruit dropping?
You could spray the vine with sugar water to attract bees. This may get you some pollination!
