|We have several giant liriope that bear the purple flower. My question is these plants are six years old and very healthy but they are very large. It seems that they reach a point when they can no longer hold themselves upright and they begin to droop over the walkway causing them to be walked upon. Is there a way and time to trim these plants? We have cut a few back as an experiment but they don't seem to regenerate themselves. Thanks very much for any help you can offer. Becky|
Liriope of all types can be cut back in mid to late winter, just prior to the onset of new growth which is usually in late winter or early spring. Then new growth comes in and fills in giving the plants a fresh new look. If the plants are getting too large and flopping over consider limiting water and fertilizer as this may help a little. The giant liriope really doesn't need fertilizing anyway and in your climate rainfall takes care of the watering needs in most seasons.
Thanks for the question. Please stop in again soon!
