Arizona Ash Problem?

Question

I have two arizona ash trees (6 yrs. old) that are not growing and turning yellow. They are about 10 ft tall but look still like saplings. Last year, I planted another and and has grown 10 ft.in one year. I researched and found out that iodine could help. I did add it and nothing has happened. What could be wrong?

Answer 1

You need a soil analysis. Arizona ash is a fairly weak tree anyway. I grew up with them but dont like them because of this.
