No matter whether the seedlings are pruned when they leave the nursery, before planting, the crown of the seedlings must be pruned to varying degrees to reduce the moisture emission of the seedlings, maintain the balance of the tree potential, and be beneficial to the survival of the seedlings. The pruning amount varies according to different tree species and landscape requirements.

Pruning of flowering shrubs and vines should comply with the following provisions: bare-rooted seedlings with soil balls or soil in wet areas and flowering shrubs with flower bud differentiation in the previous year can be pruned without pruning, only dead branches and branches of diseases and pests can be pruned; Shrubbery with obvious branches and new branches with flower buds should be appropriately pruned according to the tree potential to promote the growth of new branches and renew old branches; Large shrubs with dense branches can be moderately thinned. For grafted shrubs, the sprouted branches on the rootstock below the joint should be cut off; Shrubs used as hedges can be trimmed according to the design requirements after planting, and hedges that have been cultivated and shaped in nurseries should be renovated after planting; Climbing and vine seedlings can be cut short, and climbing seedlings can be thinned with staggered branches and horizontally growing branches.
