The soil should be moist but not waterlogged. The plant can withstand short periods of inundation, but long periods can cause root damage.
Fertilization Requirements
Stachys zeyheri Skan does not require heavy fertilization, but adding organic matter to the soil can provide the necessary nutrients for healthy growth. A balanced fertilizer can also be applied during the growing season to help with flower production.
Cultivation Methods
Stachys zeyheri Skan, also known as Thatching Lambs ear, is a perennial plant that thrives best in well-drained soils and sun exposure for at least six hours a day. It is advisable to plant the seedlings in early spring to allow them enough time to develop adequately before the onset of winter. Ensure you space the plants adequately to allow them enough room to spread.
Watering Needs
Stachys zeyheri Skan requires moderate watering, usually once a week. The plant prefers well-drained soils, and it is advisable to avoid wetting the foliage during watering as this may cause root rot or fungal diseases.
Fertilization
Stachys zeyheri Skan thrives best in nutrient-rich soils. It is advisable to apply a balanced fertilizer during the early stages of growth, usually in the first six weeks. The plant requires a slow-release fertilizer every three to four months to maintain its lush growth and vibrant flower production.
Pruning

The best time to prune the plant is usually in early spring to promote lush growth and encourage vibrant flowering in the summer. To prune the plant, use a clean, sharp garden shear to cut back the stems to an inch above the base.
Propagation of Stachys zeyheri Skan
Stachys zeyheri Skan can be propagated by seed or vegetatively. The following are the propagation methods:
Seed Propagation
The seeds should be sown in a well-drained soil mix, kept moist and exposed to light. The best time for sowing the seeds is in the spring. It takes approximately three to four weeks for the seeds to germinate. Once the seedlings reach a height of approximately 8cm, they can be transplanted into individual pots and grown until they are mature enough to be planted out in the garden.
Vegetative Propagation
Stachys zeyheri Skan can be propagated by division, cuttings or layering:
Division: The plant can be divided in the spring or autumn. The roots are carefully dug up, and the clumps are divided into smaller sections, each with a few roots attached. The divided sections are replanted at the same depth, in a well-drained soil mix, and kept moist until new growth appears.
Cuttings: The cuttings should be taken in the spring or early summer when the plant is actively growing. The cuttings should be approximately 10cm long and taken from the non-flowering stems. The leaves should be removed from the lower half of the cutting, and the cut end should be dipped in rooting hormone. The cuttings are then planted in a well-drained soil mix, kept moist, and placed in a warm, well-lit area. The cuttings usually take four to six weeks to root.
Layering: Layering is done by bending the stem to the ground, covering it with soil, and securing it in place with a U-shaped wire. The layered stem should be watered regularly, and in a few months, roots will form at the soil level. The new plant can then be separated from the parent plant and transplanted.
