Question

When is the best time to split perennial flowers?

Answer 1

A very hardy perennial can be split in the fall as well.  Early spring is better.  Depends on how harsh your winter is as well.

Answer 2

In the spring when the roots still don't have much growth to support. You also don't want to disturb the soil and roots just before winter sets in.

Answer 3

As mentioned late fall or early spring..the reason is you want to split/do cuttings/or propagate perinials when they are not focusiing on blooming and growing..You want to split/root these when they are dormant on growing leaves or blooming and they can concentrate strickly on growing roots..All thier energy will go into getting a healthy root system first...and not waste it on leaves and blooms, thus making a not deep enough or healthy root system
