Today, I made a visit to my son’s house to clean up his mondo grass. It is also called dwarf lilyturf (Ophiopogon japonicus). I have even heard it called baby monkey grass. It is a beautiful ground cover, and my son planted it around the base of this pot about three years ago. This area gets full afternoon sun. I think this is one reason the tips burned so much. Mine, which is in shade, got very little winter damage. If it has no winter damage, I generally do not touch it. But in this case, I thought a good shear before the new shoots came out would improve the look immediately and long term. The key here is to cut it off (I used shears) just below the burned foliage tips. I think you will see the improvement is instant and, when the new shoots come out, soon it will have a green, fresh look all summer and fall.
