Planting & Care

Select a full-sun spot with well-draining soil, digging a hole twice the width of the root ball. Space container trees with adequate drainage and room for growth. Water deeply after planting, then maintain consistent moisture during the growing season while allowing the soil surface to dry between waterings. Apply citrus fertilizer three to four times yearly in late winter, late spring, and early fall. Prune in late winter to remove dead wood and improve structure, and consider planting multiple trees to significantly boost your fruit yield.
