Feed Miracle Grow 20-20-20, Epson Salts, Superthrive, Sprint 138 iron chelates, Fulvic & Humic acids, ( substitute Miracid 50-10-10+Copperas for acid lovers) June, July & August.

Retains moisture perfectly for me in Michigan, zone 6b, (equal climate moisture year around). Water once a day (late) in summer any day that it doesn't rain. Full sun for most trees except JM from June 1st to mid-August in 1/2 day sun.
