Answer: You are headed in the right direction. It sounds like your plants are suffering from iron deficiency which can be a result of a too-high pH. I would recommend applying chelated iron to take care of the deficiency, and using sulfur each spring (beginning this year) at a rate of 1 oz. per plant to lower the pH. Water both of these in. Fertilizer in the form of well-rotted compost scratched lightly in around the plants is a good idea in the spring too. Adding peat or clean sawdust or shavings will aid in acidifying the soil and in weed control. Blueberries are shallow rooted and need consistent water.
