Ginnala maple with chlorosis
We have a Acer ginnala ÂFlame' maple tree with 3 trunks, in its 5th season and suffering from chlorosis (iron and magnesium deficiency). Does anyone have advice on how to help the tree take in iron?
We will try deep root fertilization in the fall. I've also heard about a new treatment via a tree IV (injecting iron and magnesium into the trunks) but this sounds pretty radical.
In the meantime, I'd sure like to do something to help the tree. Thanks in advance for any info.
We're in Colorado (terrible clay soil here!).
