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.
Chill hours: None.
Heat tolerant: All day part shade and extra water are needed above 90°F.
Sun: Full sun to part shade. Intolerant of full shade.
Drought tolerant: Yes, especially in winter.
Water after becoming established: At least weekly in hot weather, every two weeks in spring and fall.
The roots are intolerant of flooding.
Soil: Well drained, low to high in organic content, moderately salt tolerant,
pH 5.6-7.8 (acidic to slightly alkaline).
Fertilize: Apply an organic fertilizer every two months during the growing season.
Feed citrus micronutrients twice during the growing season.
Mulch: Provide a 2-6" layer of organic material, keeping it 8-12" from the trunk, to reduce moisture
Spacing: 20-25' between trees, 25' from any structure.
Planting: This tree cannot be grown in a container.
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.
Prune: Remove grass and weeds around the seedling for the first three years to avoid competition.
Litter: Leaves during leaf-changeover.
Propagation: Air layers grafted onto rootstock. The seed cannot be dried or frozen, must be
used soon after harvest, and do not grow true to the parent.
Uses: Edible fruit, ornamental, shade. Seeds within the fruit can be roasted and then ground
into flour or eaten whole.
The natural northern range for this tree is the north coast of Mexico's Gulf of California.
