Pruning and shaping of Acacia bonsai: After flowering, the residual flowers should be cut off in time to avoid consuming too much nutrients due to pod setting and affecting plant growth. Albizia Albizia grows fast, but its budding ability is weak, so its branches are sparse. Usually, attention should be paid to retaining the lateral buds to make the crown full, but the branches that affect the tree shape should be cut off, such as parallel branches, cross branches, twigs, pest branches and redundant internal branches.
