Transplanting a plant, also known as rerooting or repotting, is the process of moving a plant from one pot to another. This is done to provide the plant with more space for growth, or to change the soil type or drainage. Rerooting involves taking the plant out of its current pot and replanting it in a new one, while repotting involves transferring the plant to a larger pot without disturbing the roots. Both processes are important for maintaining healthy plants.
