Lamb’s Ear, or Stachys byzantina, is a much-loved perennial known for its distinctive fuzzy, silver-gray foliage that provides unique textural contrast in garden beds. This low-maintenance plant often forms dense, spreading mats, and gardeners commonly need to move it due to overcrowding of the original clump. Relocation may also be necessary if the initial planting site proves too wet or does not offer adequate sunlight for healthy growth. Understanding the proper techniques for transplanting ensures the perennial quickly reestablishes its root system in its new home.
Optimal Timing for Moving Lamb’s Ear
The success of moving any perennial depends on minimizing transplant shock, which for Lamb’s Ear means choosing a time of mild temperatures. The preferred window is early spring, just as the plant emerges from dormancy and shows new growth. Moving the plant at this stage allows the root system to establish itself in cool, moist soil before summer heat arrives.
Alternatively, early fall is suitable, provided transplanting occurs at least four to six weeks before the first expected hard frost. Avoid transplanting during the peak heat of summer, as high temperatures place excessive stress on the plant’s ability to absorb water and survive.
Preparing the New Location and Plant
Select a site that provides full sun to partial shade, ideally with protection from intense afternoon sun in hot climates. Lamb’s Ear requires well-draining soil to prevent root rot, a common issue due to its woolly foliage that retains moisture. If the soil is heavy clay, amend the planting area with coarse sand or well-rotted compost to improve drainage and aeration.
The new planting hole should be dug to a width approximately twice the diameter of the existing root ball. Adequate moisture is paramount; give the existing plant a thorough, deep watering about 24 hours before digging. This pre-soaking ensures the root mass holds together cohesively, minimizing disturbance when lifted.
Step-by-Step Transplanting Procedure
Lifting the Plant
The physical process of lifting the plant requires careful consideration for the root system. Use a sharp spade to cut a wide circumference around the base of the plant, ensuring the cut captures the majority of the fibrous roots. Gently work the spade underneath the root mass to lift the entire clump from the soil, minimizing tearing or crushing of the roots.
Dividing the Clump
Since Lamb’s Ear often requires division due to its spreading habit, this is the ideal time to separate the clump. Large masses can be divided by hand-pulling apart the naturally occurring rosettes or by using a clean, sharp knife to cut the root ball into smaller sections. Each new section must possess a healthy amount of foliage and an intact, viable root system to ensure successful establishment.
Replanting
Place the divided section into the prepared hole, ensuring the crown of the plant (where stems meet roots) is level with the surrounding soil surface. Planting too deeply can lead to crown rot, while planting too shallowly can cause the roots to dry out. Backfill the hole carefully with soil, gently firming the mixture around the root ball to eliminate air pockets.
Essential Care After the Move
Immediately following the transplant, saturate the soil around the relocated plant with a deep watering. This initial soak settles the soil and establishes contact between the roots and the surrounding medium for water absorption. For the next two to three weeks, maintain consistent moisture as the plant focuses on generating new roots.
The soil must not become waterlogged, however, as Lamb’s Ear is highly susceptible to rot. Monitor the foliage daily for signs of transplant shock, such as temporary wilting or slight yellowing. If the weather is warm, providing temporary shade for the first few days reduces moisture loss and stress. Always apply water directly to the base of the plant, avoiding the fuzzy leaves, which can trap moisture and predispose the plant to fungal issues.
