Separate the Succulents
Next, separate an overgrown pot of flamingo-head gasteria (Gasteria x hybrida). When succulents become overgrown in their pots, water flows over and off the roots rather than being absorbed into the plant (Image 1). Using a sharp knife, open up the rootball and remove young shoots. Due to the high water content of succulents, to prevent rot possibly developing at the site of the cut, new shoots and their roots should be left exposed to air for as long as four days to harden off the break points (Images 2 and 3).
