Why are the Tangerines on my tree not turning orange? There are lot of them on the tree. It's planted in the ground btw. And they are quite big as well, but have stayed green for a couple of months now.

Make sure the tree is receiving adequate water, and also though Tangerines are not quite as heavy of a feeder as Orange trees, they do need a fertilizer applied in spring and once during the active growing season for enough nutrients.
I do think your tree just needs more time. Most Tangerines are ready for harvest during the winter or early spring.
The Fairfield cultivator is an earlier variety and is generally harvested in October but the Honey types are not ready until January.
