Can you make a 20 year old orange tree bloom?

My father started an orange tree for me over 20 years ago. It has never bloomed or produced fruit. Is there anyway to get it to?Can you make a 20 year old orange tree bloom?
I don't know what you've done in the past-- but ....


first thought-- talk to an old orange grower


second thought-- google an ag university that does citrus


third thought-- google citrus itself.


Because---- frequently, plants don't bloom because they are missing something-- might be small-- might not be.

Hey,


I think it takes two to tango? Buy another tree so they can cross pollinate!
