how to trim liriope
After a severe drought or brutally cold winter, the evergreen foliage of liriope often looks tattered and unkempt. In early to mid-spring, give liriope plants a haircut by shearing off all foliage with pruners or a weed-cutter to a height of 2 inches. Soon the new spring growth emerges and rejuvenates the clumps with exceptionally good-looking, vibrantly colored leaves. Don't do trimming past midsummer or in the middle of a severe drought. Gardeners sometimes choose to trim their liriope plants every year each spring to create the most beautiful foliage plants.
