Help! the blooms keep falling of my fruit plants!?

Question

i have a passion fruit and pomergrante plant. every time the plants bloom the blooms die and fall off. i dont know why. i think it may be because the plants arnt mature or old enough yet (just planted this year) it could also be because i do not live in the areas permitted for growth, though the plants seem to be thriving. whats wrong???

Answer 1

Many flowers, vegetables and trees will drop their blossoms if it gets too hot.  In temperate climates that's between 85-90F.  Either provide more shade and more water and feed a fertilizer high in phosphorus.  Phosphorus helps blossom growth.

Answer 2

My mom sprays sugar water onto her tomato blossoms to keep them from dropping.  Could work?
