When is the best time to divide ornamental grasses? How often do I need to divide them?
Some ornamental grasses can grow for many years without needing division. Their low-maintenance characteristics are one reason they’re so popular. Others may need more frequent division. If a clump of ornamental grass begins to die out in the center, it’s time to divide. Generally, early spring is the best time of year to divide ornamental grasses.
