I'm aware that due to the high PH of my soil, (7.6), here in central Broward County, that the mango tree's ability to absorb iron is blocked. Thus, my tree exhibits signs of chlorosis.
I purchased Southern Ag's Chelated Liquid Iron. About 10 days ago I applied it as a soil drench. Yesterday I applied it as a foliar spray. I haven't yet seen any improvement. How long should it take to see an improvement in the tree?
