Liriope, often recognized as monkey grass or lilyturf, is a durable, grass-like perennial favored for its effectiveness as a groundcover and edging plant. It is known for its tolerance to various conditions and its ability to form dense clumps of foliage. Transplanting mature liriope is an excellent, cost-effective way to propagate the plant, increase its presence, or manage its spread. Successfully moving established clumps requires careful timing and specific techniques to ensure the new divisions thrive.
Optimal Timing and Site Preparation
The most favorable time for transplanting and dividing liriope is during the plant’s dormant period, ideally in early spring just before new growth emerges, or in mid-autumn. Moving the plant when temperatures are cooler and growth is slowed significantly minimizes the physiological stress experienced by the root system. Performing the task during dormancy gives the plant a better chance to establish roots before the demands of summer heat or winter cold.
Preparing the new planting site must be completed before any excavation begins. Select a location that offers well-drained soil, as liriope struggles in constantly soggy conditions. Improve the soil structure by incorporating organic matter, such as compost, which helps with drainage while retaining adequate moisture. Dig the receiving holes to a width at least twice the diameter of the root divisions but maintain a depth equal to the existing root structure.
Gathering the necessary tools, including a sharp spade or shovel, a trowel, and a tarp or wheelbarrow, streamlines the process. Preparing the site first prevents the dug-up root balls from drying out. This preparatory work sets the stage for a quick transition and reduces the plant’s exposure to air and sun during the transfer phase.
Excavating and Dividing Clumps
Begin by carefully lifting the existing liriope clump from the ground. Use a sharp spade to cut a circle approximately one inch outside the perimeter of the foliage, driving the tool deep enough to sever the anchoring roots. Once the circle is cut, lever the entire clump out of the soil, ensuring the dense root ball remains mostly intact.
After removal, gently brush off excess soil from the root ball to expose the tangled mass of fibrous roots and crowns. Liriope forms a tight, solid root structure that must be forcefully separated to create viable new plants. Use a sharp, sterilized serrated knife, a soil knife, or the edge of a spade to cut straight through the dense mass.
Continue this process until the original clump is broken down into smaller sections, each containing healthy roots and at least one intact crown. Even small sections can successfully grow into new plants. Keep the newly exposed roots moist by covering them with a damp cloth or placing them in a shaded area until they are ready for replanting.
Immediate Replanting Procedures
With the new divisions ready, place each section into its prepared hole, paying close attention to the planting depth. The crown, the base where the leaves emerge, must be positioned precisely at the level of the surrounding soil. Planting the crown too deep can lead to rot, while planting too shallow causes the roots to dry out quickly. Adjust the soil beneath the root ball to ensure the crown aligns correctly with the grade.
Backfill the hole with the amended soil, carefully working it around the entire root structure. Firm the soil gently using your hands to eliminate air pockets and ensure root contact with the surrounding earth. Do not pack the soil excessively, as this impedes the water and air movement necessary for root growth.
The critical step following replanting is the initial deep watering, which settles the soil and eliminates any remaining air pockets. Water the area slowly and thoroughly until the entire root zone is saturated to a depth of at least six inches. This deep soaking helps the roots immediately begin the establishment process.
Post-Transplant Care for Successful Establishment
The first growing season requires attentive care to ensure successful establishment. Maintain a consistent moisture level in the soil, favoring deep, infrequent watering over shallow sprinkles. This practice encourages the development of a deep root system that can withstand future periods of drought.
Watering once a week, or more often during hot conditions, is sufficient to keep the soil damp but not waterlogged. While liriope is not a heavy feeder, a light application of a balanced, slow-release fertilizer can be beneficial in early spring to support new growth. Avoid applying fertilizer immediately after transplanting, as this can burn the newly disturbed roots.
To encourage new foliage and reduce strain on the root system, consider trimming the existing leaves back. Cutting the foliage down to about an inch or two above the soil line minimizes the plant’s moisture loss through transpiration. This action directs the plant’s energy toward root production, which is the foundation of its long-term success.
