I bought the minor nutrient mix sold by Pine Island Nursery (manganese, sulfate, chelated iron) and I'm applying it to my recently planted trees, 3 to 5 feet tall and planted from July '14 to October '14 (I'm not treating the ones planted in the last 4 months). The label says to mix at 1 tbsp. per gallon, but doesn't indicate how many gallons to apply. I've started applying at 1/2 gallon per tree. I guess I should have asked here before starting. Is that about right? I'm applying it to Mango and Jakfruit. Would it be good to apply to banana, avocado, and Jabo also?
Thanks,
