Jujubes thrive in sunny areas.
The jujube tree (Ziziphus jujuba) is a fast growing deciduous tree that grows to a mature height of about 32 feet, with a spread of about 23 feet. The tree is notable for its fruits, which may be eaten fresh or dried and are sometimes cooked for use in puddings, jellies and cakes. Jujubes thrive in warm, temperate climates.
Planting
Jujubes should be planted in their permanent position, as the tree forms a long, deep taproot that can easily be damaged if the tree is dug up and moved. Dig a hole that is large enough to fit the tree's whole root ball comfortably. If planting multiple trees, give plants between 4 and feet of space. Jujubes often self sow -- if multiple trees are not desired, plant in a location with space to mow away young seedlings.
Soil
The jujube tree is not picky about soil, and it will grow quickly even in poor, alkaline soils. For best results, plant in an open, loamy soil that is well draining. A slightly acidic soil with a pH between 5.5 and 6.5 is ideal. Trees grown in poorly draining, heavy soils are more likely to succumb to fungal disease and rot. Fertilize if desired with an organic fertilizer such as cottonseed meal in late winter or early spring.
Water
Though the jujube tree is quite drought tolerant once established, the tree will require regular watering for the first few years as it forms its deep root system. Provide about 7 gallons of water per week during the first year, watering deeply and slowly. About twice a week is ideal for light soils. In the spring or winter, when rainfall is naturally heavy, watering may be reduced. Water more frequently during extended summer droughts. Poor irrigation may result in premature fruit drop.
Propagation
The jujube tree may be propagated by seed, division of suckers or cuttings. Seeds do best when sown in a cold frame. Germination may take more than a year, as the seed requires three months of warm weather and three months of cold weather. Seedlings can be planted in their permanent position in early summer. Suckers may be divided during winter dormancy and planted outdoors. Mature wood cuttings may be taken in November, December or January.
