Bergenia grows into clumps and when they become overcrowded, usually after three or four years of flowering you can dig and divide the clumps. The best time to divide or set out new plants is early- to mid-autumn. Bergenia grows from rhizomes. Rhizomes are thick, fleshy stems that grow horizontally just beneath the surface of the soil, while tubers are swollen sections of stems or roots. As new rhizomes and tubers are produced, the plants expand outward, and small roots grow to anchor them to the ground. Once you've gotten the rhizomes out of the ground, shake or wash off the soil so you can see what you're working with. Use a sharp knife or pruning shears to cut rhizomes apart, making sure that each piece has green leaves and roots attached. Best wishes with your project!
