How Old Are Citrus Trees When They Start Blooming?

[citychickinthecountry]

I was wondering at what age citrus trees start blooming. I have some bushes/trees (oranges/grapefruit/lemons) that are almost 3 years old. None of them have bloomed yet and I was just wondering when they might start.

I fertilized them this year in the hopes that I might get some blossoms, but nothing yet.

Actually, none of my existing bushes/trees have blossomed yet (I know it's a tad early for my Kumquat bush).

I also have what I believe is a Kumquat bush in my front yard (near a grapefruit tree) that is about 4 years old that hasn't blossomed as long as I have had my house! Ugh!

Your trees may not be quite old enough yet Citychick. Generally the smaller the fruit ( limes, tangerines etc. ) the earlier/ younger they bear. Navels and grapefruit can take up to ten years to fruit.
My trees were in for 3 or 4 years and didn't bear, and then we moved, so I never got any fruit from them.

How do the leaves look? They should be a deep green.
Citrus are kind of heavy feeders and need frequent fertilizing, like every few months when they're young.
