Planting & Care

Select a location receiving abundant direct sunlight, as more sun translates to heavier fruit production. Plant in well-draining, acidic soil—whether in garden beds or containers with drainage holes. Water young trees once or twice weekly, being careful not to create soggy conditions that invite root rot. Apply acidic fertilizer three to four times annually during the growing season. Protect your tree from sudden cold snaps when possible, though it can tolerate occasional frost once established.
