How to prune and plant jujube trees in spring
The small crown has a thinning layer shape and a stem height of 80 cm and 90 cm, which suppresses the secondary branches on the trunk and promotes the development of 3 jujube heads, so that the uppermost jujube heads extend upward and become the trunk extension branches, and the lower 2 jujube heads are cultured as the main branches. In the second year, the trunk branches were cut short by about 60 cm, except those under the cut mouth.

Management of planting jujube after defoliation
1. Applying fertilizer and water consumes a lot of nutrients in the growth and fruit of jujube for one year, which needs to be replenished in time. After the jujube leaves fall, the soil is fertilized before freezing. If it is not applied a year ago, it should be replenished before sprouting in early spring. Fertilization can be spread or ditched. To spread fertilizer is to put manure in a circle.
