While there is not first or last date to fertilize blueberry bushes, the general rule of thumb is to fertilize blueberries in the spring before their leaves have grown in. This is so that the blueberry fertilizer has time to penetrate the soil and make it to the roots of the blueberry bush before it enters active growth. You should be fertilizing blueberries once a year. Typically, they do not need fertilizing more often than this.
Best Answer: In the spring I give each of my blueberry bushes 1/2 pound of 13-0-13 fertilizer, spread in a 5 foot circle around them. In the fall they get 1/2 pound of the same. Throughout the year they are given used coffee grounds and crushed egg shells. The coffee grounds add acid to the soil and the egg shells add calcium and help control slugs and snails. I also mulch with pine straw; it adds more acid, keeps down weeds and keeps the soil from drying out too quickly. Mine have done well with this feeding schedule.
