time of year to fertilize blueberries
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.
