Carambola leaves are yellowing (forum)

LydiaB starts with ...
Hi everyone. I have a carambola which up until now has looked very healthy - despite not bearing any fruit even though it is now 4 years old! The latest batch of new growth is turning yellow (see photo). Could this be a nutrient deficiency? I give it generic fruit tree fertiliser every 6 months. My research has only thrown up iron deficiency as a possibility. Any advice gratefully accepted.

I would have said magnesium or manganese, but according to the only images I could find, it's iron. You have probably already seen this.

Is the yellowing occurring on the new or old growth of the tree?

If it

thank you all. Harry it's definitely new growth so I will try chelates. I did give it some trace elements a few weeks back but I guess it takes a while to work it's way into the system.

I have treated the carambola with iron chelates. Does anybody know how long it should take to have effect? Or how will I know? Do the already yellow leaves start to become green?

Lydia - Harrys info above was quite correct but i have found that correction most of the time will show partially in old growth but definitely in new growth in Citrus - so post us your results later if this occurs for you - no idea whats happening with your Fejoas except if its been too hot with not enough water where you are in Northern Territory?

Thanks Mark. I'm in Bellingen, northern NSW. As yet, no change in carambola in new growth and there is nothing to change in the old growth as it was fine. But as Harry said to treat the carambola again with chelates in autumn, seems to suggests that I shouldn't expect too much with this one round of treatment?
