Blueberry Mix Fertilizer 5lbs by Old Cobblers Farm

This premium 10-10-10 blend with Ammonium Sulfate is ideal for all evergreens, but it's simply scrumptious for blueberries! For a 2- or 3-year-old berry bush, give 'em 1-2 cups per plant per year, but if you've got a mature bush, shoot for 4-6 cups.
