Know when to transplant. Aloe plants have relatively short roots and heavy leaves, so they are commonly moved to a heavier pot when they become top-heavy and tip over. If Aloe vera runs out of space for its roots to grow, it may start to produce "pups" that can be moved to their own pot (see the Propagating section). If you are more interested in the adult plant growing than producing new plants, transplant it to a larger pot before the roots begin to circle the walls of its container
