Also, irrigations after a brief drought may cause fruits to split. Plant bare-root trees in January or February or whenever plants are available. Amending soil is not necessary. Spread roots over a cone of soil in the center of the planting hole, and adjust the final height until it is equal to or slightly above the original soil grade. Trees often bear some fruit the first year.
Trees require very little pruning or training.
The best time to prune for repair or shaping is late winter or early spring before the tree breaks dormancy. Fruits are borne on long-lived spurs, much like apples. Root suckers can be a nuisance, but most gardeners consider them a minor one. The jujube is virtually disease-free, and most insects ignore it. In desert regions, you'll probably have to compete with birds for the fruit, and Texas root rot sometimes occurs.
