My own backyard Tangerine

This is my Kinnow Mandarin in my back yard. The plant is three years old and this is the first time it has had an actual harvest. Before this it was just a few fragrant flowers and nubs of fruits that soon shriveled and died. I'm wondering if I am not giving it enough water, I have never fertilized it. Next year I will look into this and try to do the right thing.

I just ate my first the other day and it's nothing like you buy at the store. This is not bland but a very strong taste, a little sour but I like that. The only thing I don't like is that it has some big seeds. All in all I'm happy with it.
