The term "Overpotting" means planting a bonsai tree into a pot that is too large for its root system. This can have negative effects on the tree's health and growth, as the excess soil can retain too much water and cause root rot, or lack enough nutrients and oxygen for the roots to thrive. Overpotting can also make it harder to control the shape and size of the bonsai, as the tree may grow too fast or too slow. Overpotting is different from repotting, which is the process of transferring a bonsai to a new pot that fits its root system better. Repotting is usually done every few years, depending on the species and age of the tree . Overpotting should be avoided, as it can harm the bonsai's health and aesthetics.
