Six years later, and I finally have a crop from my Mandarin oranges. This tree produced over fifteen. It could have easily bore 4 or 5 times that amount -- 80% of the tree had no fruit.
It's incredible how long these take to ripen. The tree bloomed in March, and now, at the end of November, some are still ripening.
My other Mandarin, different species, planted at same time. This tree is way smaller, and it produced 5 fruits. But, they are very big. These still have a long way to go to ripen. They are yellow now, and will be bright orange when ripe.
I possibly have the only producing citrus tress in Central Texas. The lethal Texas freeze of 2 years ago wiped them all out. There were several trees in my neighborhood, all different sizes and maturities, and they all died. I went to a really lot of trouble to tent mine, and then I ran an incandescent bulb under each tent for heat.
