Hostas continue to be one of the most popular and easy-to-care-for perennials in Zone 3 through 8 gardens. It's no secret that many gardeners want to divide their hostas to spread the hosta love around their own garden or to share divisions with other hosta lovers.
Because hostas are such a tough plant, you can divide them in spring, summer and fall, and dividing hostas in each season is explained more fully later.
Hostas are a long-living perennial, and over time, the center of the plant may begin to die out. This is commonly referred to as center die-out, clump die-back or fairy ring. The later is a whimsical nickname given where the problem is said to result from fairies dancing in the middle of the plant.
