We recommend first testing the soil where you plan to plant your tree, and add any amendments needed before planting. This will help the young tree thrive in a balanced environment while it is establishing its root system. After its first season, it will be much more tolerant to variation in soil condition and should only need a balanced fertilizer once a year. Choose an organic fertilizer balanced for trees (like Espoma Tree-tone) and mix it into the drip line around the tree in early spring, before any new growth has begun.
