Hostas don't require division for the health of the plant, but they can be divided. Hostas are famously long-lived plants that can be divided and shared throughout the yard, or you share them with fellow gardeners. Some gardeners prefer to divide hostas to maintain a neater appearance -- they multiply quickly in naturalized gardens! The best time to divide and transplant your Hostas is in the spring; although you can transplant them in the summer or early fall if you provide enough water to help your transplants settle in. Wait until a few inches' worth of leaves sprout out of the ground. Then, dig up your hosta gently. Brush off any excess soil, and divide the clump of hostas into smaller pieces. Now, you're ready to transplant! Hostas are one of the hardiest, easiest-to-please plants on the market. Most gardens can host a variety of different hostas -- from miniature, mouse-eared varieties to huge, dramatic, variegated leaves. Hostas are like big, easy-care houseplants -- except they live outdoors.
