When moving a plant to a new location, it is advisable to prune some of its leaves in order to reduce water loss. Pruning helps to decrease the surface area of the plant, which in turn reduces the amount of water that can evaporate from the leaves. This is especially important during the transplanting process when the plant may experience stress and have limited access to water. By cutting back some of the leaves, the plant can conserve moisture and increase its chances of survival in the new environment.
