The uprooting process prepares trees to become quickly accustomed to a new environment before transplantation takes place in order to maintain the tree's quality and appearance. Usually the process is started six months to a year before the tree is moved. The sooner the process is started, the longer the tree has to become accustomed, and the higher its chances of survival.
據了解，斷根的目的，主要是讓待移植的老樹及早適應移植環境的前置動作，以保存樹的品質與樣貌，通常得於移植前六個月至一年間進行，愈早進行斷根作業，才能讓樹的適應期拉長，提高移植存活率。
