Liriope - Trimming or Pruning

Trimming or pruning can make liriope more luxuriant.

"Liriope Muscari", or the larger leaved varieties, have only one growth cycle; therefore, you do not want to damage this cycle. This is why a close examination will tell you how far back the plantings can be safely pruned.

Severe winter weather can cause Liriope to become quite unsightly. The tips of the foliage burn, turn brown, and appear to be severely injured. Generally the plant is not damaged to any great extent other than becomes unsightly.

Remove damaged foliage…

The damaged foliage can be removed without any damage if it is trimmed properly. In Georgia, the new growth cycle may start as early as February depending upon the weather. The only limitation or restriction on pruning or trimming is to accomplish this task before new growth buds begin to develop and thus would be cut back.

This can be determined by looking down into the clump after you have separated the foliage. Where practical and safe, a lawn mower may be used to trim away the unsightly foliage. Adjust the mower to one of the higher mowing heights to avoid cutting newly developing shoots. Hedge shears may be a more logical tool for trimming individual clumps.

Clean up and discard all trimmings for a neat, uncluttered appearance.

Liriope Spicata and Ophipogon have several growth cycles of underground runners. However, since they are slower to redevelop after pruning, it should not be severely trimmed or pruned. During early fall the old flower spikes may become unsightly. They can be pulled or trimmed out to make your plantings much neater.

Fertilize and water…

Remember that fertilizer and water will give you a much more attractive planting so do not neglect them. Fertilize in early spring and midsummer with your general purpose lawn or garden fertilizer. Rinse away any fertilizer material that may fall on the foliage or in the center of the clumps. Water weekly with a thorough application of water for a faster and more attractive growth. Liriope can be one of your most effective and satisfying plantings.
