Foliar feeding was brought up on the Organic Gardening post. I was curious the various products people have had used with good results. I have always used the Southern Ag Citrus Spray for foliar feeding.
What products, organic or not, are you using?
My big question is why not buy iron sulfate and magnesium sulfate (Epsom salts). Both are cheap. Make foliars with them with a little soap to adhere better to leaves and such. Are iron and magnesium chelates better for foliar feeding than the simple sulfates? I know that Souther Ag foliar (which I have) has a few other chelated and non-chelated elements .... zinc and manganese.
Southern Ag citrus foliar seems to be chelated elements and plain old unchelated sulfates
