I have a passion fruit plant that is about 4 years old, and all the fruit it ever given were two little cracked marbles that fell off the plant quickly.
I water it regularly, I attempted to water it more and sometimes less to see if it changes anything.
I recently noticed that flowers on other passion fruit have a lot of yellow pollen on them, and mine don't have any at all (Seriously, not even a slight bit)
What could cause this? should I try giving it a specific fertilizer? or should I just pull it out?
