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.
During the second year, broadcast fertilizer away from the base of the plant in a twenty-inch radius at the rate of Â½ pound of 10-10-10 per plant in early March, May, and July. For mature muscadine vines, apply one to two pounds of 10-10-10 in early to mid March. In mid June, make another application of one pound of fertilizer. Blueberry bushes prefer a soil pH around 4.8. Blueberry bushes canât tolerate excessive amounts of fertilizer.
