What do you feed blueberries in the spring?

Why are blueberry leaves turning yellow?
Chlorosis in blueberry plants occurs when a lack of iron prevents the leaves from producing chlorophyll. This nutritional deficiency is often the cause for yellow or discolored blueberry leaves, stunted growth, reduced yield, and in some cases, eventual death of the plant.
Is alfalfa meal good for blueberries?
Avoid using alfalfa pellets or meal on plants that like acidic soil. Understand that the product is quite alkaline, so it would not be good for plants such as rhododendrons, camellias and blueberries.
