Article: Hostas can be propagated by dividing a mature plant. The best times for dividing plants are in early spring or late fall, about a month before the frost comes. Hostas do not need to be divided, but you can divide them if you want to propagate more plants, or want to give them away to other gardeners. As your hostas grow, they will produce new offsets every year. You can easily divide the hosta without digging up the entire plant by locating and removing these new offsets. The offsets will look like new clumps of growth that pop up around the parent plant.
