Help me iron out my mango problems!
I have a cogshall mango in a clay pot outside (in Ft. Lauderdale) and it's planted in Vigoro organic potting mix, and I'm pretty positive it has an iron deficiency. A garden center recommended I spray Southern Ag chelated liquid iron on the leaves (so I bought it), but should I pour it on the soil instead? Would that acidify the soil (I've read that if the soil is too alkaline, iron isn't in a form available to the mango)? Is the clay pot contributing to the problem? Also, I dumped in some pellets of 6-4-6 fish and kelp fertilizer - should I scoop those out before I apply the iron?
