Cultivation and Uses
USDA hardiness zones:
9-12. Young trees are hardy only to 32°F. Cold hardiness gradually improves with age, and
very old trees may withstand 20°F, although small branches and leaves will be killed.
All day part shade and extra water are needed above 90°F.
Not in high temperatures.
Full sun in moderate temperatures to part shade above 90°F. This plant is intolerant of
Locate in part shade in well draining soil. Space the male and female trees 20' apart. If the
trees will be pruned every winter to maintain their height at 7', they can be spaced 8'
apart. These trees cannot be grown in a container.
Well drained, low to high in organic content, pH 5.6-7.8 (acidic to slightly alkaline). This
plant is moderately salt tolerant.
Apply an organic fertilizer every two months during the growing season. Feed plant micronutrients
in irrigation water twice during the growing season.
Water after becoming established:
weekly in hot weather, every two weeks in
spring and fall, and every four weeks in winter. The roots are intolerant of flooding.
Spread organic mulch inside the drip line and 8" away from the trunk to reduce moisture loss
and lessen root area temperature extremes.
First Year Care:
Water twice a week in high temperatures. Protect from freezing during the first 3 years.
Do not prune the first 2 years to speed growth.
This tree can be kept pruned to a height of 7' for easier fruit harvesting. Remove grass
and weeds around the plant for the first three years to avoid root competition.
Leaves during leaf-changeover.
Cuttings grafted onto rootstock, air layering. Seed must be sown soon after harvest, do not
grow true to parent, and are not viable dried.
Edible fruit, ornamental, shade. Seeds within the fruit can be roasted and then ground
into flour or eaten whole.
