Strawberry Guava Aborted flowers

[Future]

So my oldest and biggest tree has never set a fruit.  It’s at least 12 years old and sets flowers but petals brown and flowers degrade before opening.  This seed was from Hawaii. It’s in a pot is busted through and earthed so I wonder if the restriction is the cause. Other tiny trees set fruit without issue.

Anyone else see this?

Interesting given it’s invasive status in Hawaii.

Mine flowers like crazy and produces fruit on its own despite being solo, with limited pollinating insect access, and likely not a single other cattley guava in the state. 

I'm not sure if these can be dioecious, that's the only explanation I can think of if you have such an old tree that flowers but produces no fruit.  Perhaps its a male?  I'm purely speculating here, somebody else will have more expertise.

I have two different plants grown in pots and both set fruit the first time blooming and they are probably only 1-2 years old. I think you must have one with bad genetics

Thanks guys. Maybe bad genes. When flower bud begins to open, petals appear white. But before opening they essentially brown and rot, fall apart.
