Hostas have a clumping root system, so to divide a plant, simply cut through the clump with a knife from the crown down. You can also pry apart the root clump with garden tools, but this won’t give you as much precision. Cutting through the roots is fine, as hostas roots quickly regrow once transplanted.
When should hostas be divided?
When to divide hostas is simple. Two times of year provide the best conditions for digging and transplanting hostas: early spring or early fall. Either timeframe yields roughly a four-week window that’s ideal for splitting hostas.
How do you thin hostas?
To thin a hosta plant, divide the clump into separate sections, each of which can be replanted to start a new plant. Though you can divide a hosta any time the ground is workable, it’s best to do it in the spring just as the leaves emerge from the ground, or in the fall about six weeks before the first expected frost.
