Small pomegranate trees with short plants, small leaves and small flowers and fruits are used as bonsai, such as fire pomegranate, four-season pomegranate and agate pomegranate. Pomegranate can be propagated by sowing and cutting. The saplings obtained by the above two methods can only be cut and stored to cultivate small and medium-sized bonsai after planting for more than 3 years.
Branch storage stage
According to the shape of pomegranate tree, cut off the trunk at an appropriate height and cut off the main branches. Pomegranate bonsai can be made into straight-stem, inclined-stem and bent-stem trees. Pomegranate trees have a certain degree of cold tolerance, and can overwinter outdoors in North China with a little protection in the leeward and sunny places. In order to make trees grow fast, it is better to plant them on the ground. Pomegranate trees like fertilizer. In addition to applying base fertilizer when planting, they should also apply decomposed thin organic fertilizer every half month during the vigorous growth period in spring and summer. Pomegranate trees grow faster. When the branch thickness reaches about 70% of the ideal thickness, cut the branches short to promote the growth and development of the lateral branches.
Forming stage
When pomegranate trees basically meet the design composition requirements, pomegranate stumps should be planted in ornamental pots with appropriate size and style in early spring. Straight stem type and inclined stem type can be planted in shallow oval pots, and curved stem type can be planted in square pots with medium depth. At this stage, it is necessary to apply more fertilizer appropriately to promote the growth of trees and better improve the shape. On the other hand, it is also necessary to take into account the needs of appreciation.
After several years of cultivation, pruning and maintenance, pomegranate bonsai has achieved the goal of viewing flowers in spring and fruits in autumn on the basis of maintaining its appearance (pomegranate does not bear fruit).
