The image on the left above is NOT a good horticultural practice! To remove a plant from its container, gently tip your plant while supporting it at the soil line with your free hand.
Be kind to your transplants. Don’t tear a developing plant out of its original container by its leaves, stems, or trunk risking ripping off foliage and roots.
When loosening potted plants, the best way is to first make certain that its potting medium is moist, then slowly tip the container over while holding one hand around the base of the plant, supporting the shifting weight of the soil as the intact plant slides free.
