Set 10 to 15 feet apart, preferably in well-drained soil of low to moderate fertility. Requires full sun. In northern zones, we recommend a southern exposure. For container culture, plant in a large tub or container, in well-drained soil, enriched with organic matter. Set outdoors after danger of frost is past, first hardening off in partial shade, then moving to a location in full sun.
During the growing season, water well during periods of drought, and mulch with hay, compost or straw to preserve moisture and discourage weeds. To develop a tree form, train 3 or 4 branches 2 to 3 feet off the ground. Prune in spring while dormant, remove dead wood and thin to keep the top open and grow within bounds.
At the northern limit of its hardiness, add a winter mulch mounded two feet above the base of the plant. For container culture, bring indoors after a few fall frosts and store in a cool, dark cellar; water about once a month to keep soil barely moist. Prune lightly each spring to keep plants within bounds and repot every 2 to 3 years as needed.
