Zizyphus jujuba

Lang has a large bell shaped fruit, ripening one month later than Li. Fruits are good fresh right from the tree. Tree is pretty with olive shaped glistening leaves. Flowers are small, yellow and scented. They can sweeten the air around the tree especially at twilight. The smell is reminiscent of grape soda. Blooming in June here, the flowers are never damaged by late spring frosts. Jujube is native to China and adapts very well in the US. Space 15'. Zones 6-9.

Jujube Care Guide

Origin
The jujube originated in China where they have been cultivated for more than 4,000 years and where there are over 400 cultivars. The plants traveled beyond Asia centuries ago and today are grown to some extent in Russia, northern Africa, southern Europe, the Middle East and the southwestern United States. Jujube seedlings, inferior to the Chinese cultivars, were introduced into Europe at the beginning of the Christian era and carried to the U. S. in 1837. It wasn't until 1908 that improved Chinese selections were introduced by the USDA.

Adaptation
The jujube can withstand a wide range of temperatures; virtually no temperature seems to be too high in summertime. Winter dormancy allows it to withstand temperatures to about -28Â° F, yet it requires only a small amount of winter chill in order for it to set fruit. The plant revels in summer sun and heat, with the lack of either limiting fruit production more than winter cold. Yet jujubes have fruited in the Puget Sound and low Cascade regions of Washington State as well as in Pennsylvania. Fruiting of some cultivars has also been reported in northern Florida. The Indian jujube, which is more sensitive to frost, is grown in Florida, but the fruit is considered inferior. Jujube trees are not particularly suitable for container culture, but can be grown in this manner in a large container.

Growth Habit
The jujube is a small, deciduous tree, growing to 40 feet tall in Florida, but smaller in size in California. The naturally drooping tree is graceful, ornamental and often thorny with branches growing in a zigzag pattern. The wood is very hard and strong. Jujube cultivars vary in size and conformation, with some being very narrow in habit and others being more widespread. One cultivar, the Contorted (So), seems to be fairly dwarfing in habit. After 30 years of growth in an average site, trees can be 30 feet tall with a crown diameter of up to 15 feet. Plants send up suckers (often with intimidating spines) from their roots, and these suckers can appear many feet from the mother plant. Currently, these root suckers must be controlled by mowing or hoeing.

Foliage
The small, ovate or oval leaves are 1-2 inches long and a shiny bright green. In the autumn, the leaves turn bright yellow before falling. As the growing season commences, each node of a woody branch produces one to ten branchlets. Most of these are deciduous, falling from the plant in autumn.

Flowers
The inconspicuous, 1/5 inch diameter, white to greenish-yellow flowers are somewhat fragrant and produced in large numbers in the leaf axils. The flowering period extends over several months from late spring into summer. However, individual flowers are receptive to pollen for only one day or less. Pollination needs of the jujube are not clearly defined, but appear to be done by ants or other insects, wasps and possibly by the wind. Most jujube cultivars produce fruit without cross-pollination . The jujube is well protected from late spring frosts by delayed budding until all chance of cold weather has passed.

Fruit
The fruit is a drupe, varying from round to elongate and from cherry-size to plum-size depending on cultivar. It has a thin, edible skin surrounding whitish flesh of sweet, agreeable flavor. The single hard stone contains two seeds. The immature fruit is green in color, but as it ripens it goes through a yellow-green stage with mahogany-colored spots appearing on the skin as the fruit ripens further. The fully mature fruit is entirely red. Shortly after becoming fully red, the fruit begins to soften and wrinkle. The fruit can be eaten after it becomes wrinkled, but most people prefer them during the interval between the yellow-green stage and the full red stage. At this stage the flesh is crisp and sweet, reminiscent of an apple. Under dry conditions jujubes lose moisture, shrivel and become spongy inside. Tests in Russia indicate a very high vitamin C content. The fruit has been used medicinally for millennia by many cultures. One of its most popular uses is as a tea for sore throat.

Location
Jujubes should be given a warm, sunny location, but are otherwise relatively undemanding. Given adequate heat and sun, the trees will thrive without any special care. They should not be planted in the shade of other trees. Our jujube's are usually grafted. When you receive your plant look for the graft union on the lower trunk. Do not let any root stock growth below the graft grow. Root stock growth can come up away from the plant. These should be pruned off and not allowed to grow.

Soil
Jujubes tolerate many types of soils, but prefer a sandy, well-drained soils and do less well in heavy, poorly drained soil. They are able to grow in soils with high salinity or high alkalinity.

Irrigation
One of the outstanding qualities of the jujube tree are its tolerance of drought conditions. Regular watering, though, is important to assure a quality fruit crop.

Fertilization
Fertilizer requirements have not been studied, but jujubes appear to do well with little or no fertilization. Light broadcast applications of a balanced fertilizer such as 8-8-8 NPK at two-month intervals during the growing season would probably speed growth. Do not fertilize until the newly planted tree has several months to get established.

Pruning
Trees that have not been pruned produce as well as trees that have been pruned. Extensive winter pruning, however, will keep the plants in better health and produce more easily obtainable fruit.

Most jujube cultivars produce fruit without cross-pollination, but seeds from such self-pollination are usually not viable (such as from the Li or Lang cultivars).

Jujubes should be set out 10 to 15 feet apart since they require high light intensities for good production.

Pests and diseases
The Chinese jujube appears to have no serious disease, insect, or nematode pests in the U.S., hence, no spraying is necessary. Only the pocket gopher has shown a liking for the roots. One disease, witches broom, is prevalent in China and Korea and could be destructive to a new industry if allowed to enter into non-endemic areas.

Harvest
The crop ripens non-simultaneously, and fruit can be picked for several weeks from a single tree. If picked green, jujubes will not ripen. Ripe fruits may be stored at room temperature for about a week. The fruit may be eaten fresh, dried or candied. Fresh fruit is much prized by certain cultures and is easily sold in Chinese, Korean, Vietnamese, and Indian markets. Tree dried fruit stores indefinitely and may have good marketing potential as it dries on the tree without the use of a sulfur preservative. Ripe fruit put into a paper bag will also dry in the refrigerator.

Recipes

Jujube Cake
1 cup sugar
1/2 cup butter
2 cups dried, minced jujube
1 cup water

Bring these to a boil then set aside to cool
2 cups wheat flour
1 teaspoonful soda
1/2 teaspoonful salt

Sift these together then add to the above mixture. Bake at 325Â° F

Candied Jujubes
Wash about 3 pounds dried jujubes; drain and prick each several times with a fork. In a kettle bring to a boil 5 cups water, 5-1/2 cups sugar, and 1 tablespoon corn starch. Add the jujubes and simmer, uncovered, stirring occasionally, for 30 minutes. Cool, cover, and chill overnight.

The next day bring syrup and jujubes to a boil and simmer, uncovered, 30 minutes. With a slotted spoon lift jujubes from syrup and place slightly apart on rimmed pans. Dry in oven, or in sun for about 2 to 3 days. Check fruit frequently and turn fruit occasionally until the jujubes are like the dates ones sees in the market.

Jujube Syrup
Boil syrup remaining from the Candied Jujubes, uncovered, until reduced to about 2 cups. Use over pancakes and waffles. Store in the refrigerator.

Other uses
Substitute the dried jujube wherever recipes call for raisins or dates. Dried jujubes are a wonderful snack that can be prepared without the use of any preservative as is so commonly needed for other dried fruits.
