##### Horticulture

Common kind is hardy as far north as southern New England, but is best suited for regions of long, hot, dry summers. It does well even in decidedly alkaline soil. The Texas jujube requires similar climatic conditions. The Indian jujube thrives in Florida and elsewhere in a variety of soils. Mountains, hills, sunny dry slopes, plains, also widely cultivated. Late fall or early winter. Tolerates poor soil. Fruits inn late fall or early winter. Medium water. Not suitable for containers. Easily grown in average, medium moisture, well-drained soils in full sun. Best in hot and somewhat dry climates in full sun. Plants tolerate alkaline soils. Mature plants have some tolerance for drought, but perform best with regular and consistent moisture. Avoid heavy, poorly drained soils. Plants will sucker from the roots. Other than pruning to keep them shapely, no special care is needed. Propagation is by seed, which should be removed from the stones before sowing.
