I have tried feeding it iron chelat and I got some color back on half of the tree but the branches were still dying. It's sitting in a pot and I don't know how long it has been in it.

From what you have said, your cumquat does sound like it is suffering. If the branches are dying back it could well be that the roots of the plant in the pot are too wet, cutting out oxygen around the roots, causing the branches to die back. Prune back those branches that have died back to encourage new growth. Citrus trees that are planted in the ground commonly suffer with phytophthora if the drainage is poor. Usually, at this time of the year, citrus will be flowering and setting fruit so it is really not the best time to the disturb your plant. If it is showing no signs of improvement, I think the best thing to do would be to take the plant out of the pot it is in, inspect its root system and repot with with some fresh potting mix. We would also suggest you water in with a Yates product called Uplift Organic Plant Starter & Root Booster. This product is designed to make the plant stronger and healthier from the roots up. Apply the product again 2 weeks later and nurse your cumquat along. Don't fertilise the plant until it shows sign of recover with fresh new growth. Place your pot in a spot that is in full sun and protect from strong winds. I am sure with a little care your cumquat will respond and continue to power on. Good luck.
