How to control fruits shriveling in passion fruit to boost crop yield?

shriveling fruits are common for passion fruits, especially ripe ones when they fall to the ground. But, if this happens earlier, it could be due to fruit fly damage, sucking insect damage, poor pollination, lack of boron, and insufficient irrigation when the heavy crop is set. Ensure your vines are provided with the proper nutrients for maximum and full growth, free from pests and diseases.
