About Jujube
Jujube, or Chinese date, is a tough deciduous tree with zigzag, thorny branches and small fruit that eats like a crisp, sweet apple when fresh and like a date when dried. It shrugs off heat, drought and poor soil, leafs out late enough to miss spring frosts, and has few pests in the U.S. Its big drawback is root suckers that can pop up several feet away and form thorny thickets; Texas A&M's rangeland guide calls it an exotic invasive.
UF/IFAS reports it in zones 5-10, doing best in 6-9, and established trees take about -20 F; Texas A&M lists zones 6-9. Fruit needs long, hot summers to ripen (Arizona Extension). It has escaped along the Gulf Coast (USDA Forest Service), and in Texas and western Oklahoma it is treated as invasive on rangeland.
When to plant
Timing is counted from your average last spring frost (and first fall frost). Sow & Tell works out the actual dates for your ZIP code.
Plant 1- to 2-year-old container or bare-root trees as you would other fruit trees, 6 to 12 feet apart, and water regularly until they settle in (Texas A&M AgriLife). Trees often flower the year they are planted, but real crops start in about 3 to 5 years (UF/IFAS; NMSU).
Soil
Grows in sandy, loam or clay soil as long as it drains fairly well; above pH 7.8 it may run short of minor nutrients (NMSU; Texas A&M).
Plant in full sun in well-drained soil; get a soil test first, since the right fertilizer depends on soil pH (Texas A&M AgriLife).
Feeding
- First and second years: April, May and June: Nitrogen fertilizer. Split the year's nitrogen into three equal monthly feedings, scattered around the tree and watered in (Texas A&M).
- Each spring after that, just before new growth: Nitrogen fertilizer; or a 3-1-2 ratio fertilizer where soil pH is below 7.5. Texas A&M suggests about 0.2 lb of actual nitrogen per inch of trunk diameter, up to 1 lb a year, spread under the canopy; use nitrogen only where pH is above 7.5.
Heavy doses of quick-release nitrogen can make fruit drop (UF/IFAS); jujubes do well on little fertilizer (Arizona Extension).
Harvest
Fruit ripens unevenly over several weeks, mostly August to October (NMSU). For fresh eating, pick from the cream-colored stage until it is red-brown but still firm; many people like the few days between the first brown color and wrinkling (NMSU; Arizona Extension). For drying, let it turn fully red-brown.
One crop a year, but fruit ripens unevenly, so you pick the same tree several times over a few weeks. Fruit left on the tree dries like raisins.

In the kitchen
Eaten fresh like a small crisp apple, or dried like dates or raisins; also candied, pickled or canned, and used in desserts, sauces, salads, soups and teas (Texas A&M AgriLife; NMSU).
Keeping it: Fresh jujubes picked at first ripeness keep two weeks or more at about 40 F (NMSU). Dried fruit keeps well at room temperature and for years in the refrigerator (UF/IFAS).
Safety: The fruit is a common food, but every jujube has a hard, pointed pit, so eat carefully (Texas A&M AgriLife). The thorny branches can hurt children and pets; keep trees away from walks and play areas (Texas A&M AgriLife).
