I had a certified arborist out yesterday for an estimate on a tree removal. I also asked him to look at my 20 year old Satsuma Tangerine tree. I know the tree looks bad. Most of the interior branches are dead with the leaves being only on the end of the branches. I know the leaves are too yellow. This winter it produced only 4 fruit. Last winter it produced hundreds! He said it looks like the tree is shutting down. He suggested putting fish emulsion on, watering well, mulching and waiting a month. If no improvement putting gypsum on and waiting a month. If no improvement putting on chelated iron.

I know he made these suggestions looking at my tree and based on his knowledge of the soil in this area which is clay.

If there is a way to post pictures on this site I'd love directions.

I'd also appreciate your feedback on his recommendations. I have been fertilizing it 4x a year with the recommended amount of nitrogen.

I have a naval orange right next to it, also 20 years old, and it looks fine. The other side of the Satsuma is a newly planted apple tree. Nothing of significance was there before. In the front of the tree is my lawn and to the rear my neighbors garden which I can't see.

Thanks,
Ginny
