I was wondering about that, Kathi.
As I mentioned the tangelo that is about 10 feet from my AZ Sweet has set fruit and the Clementine which is about 10 feet from my Key Lime both have tiny set fruit. I never saw any flowers on my Key Lime or AZ Sweet. Both are probably about 20 years old.
The tree needs to push flowers in order for the bees to do their thing... am I right? I might be wrong but I thought that's what they do. Pollinate the flowers so oranges set.
Part of me is blindly hoping "something" will happen.
