When is the best time to split hostas?
You can divide hostas most anytime, but it's best to do it in early spring (when the plants are about 2 inches tall) or in late summer (about 6 weeks before the first killing frost is expected). It's best to wait until your plants are at least 3-4 years old before you cut them into sections. However, if you are in a hurry to get more plants, chances are good that they will survive dividing the first year after you plant them. Dig around the entire clump, then lift the plant, soil and all, from the hole. Brush away enough soil so you can see the roots. Wash away the remaining soil. Use a sharp knife to cut the clump into sections. Leave as many roots as possible on each section. Replant divisions right away, and keep them moist.
