Soil Requirements
Stachys bachmannii Gürke prefers well-draining, slightly acidic to alkaline soil with a pH range of 6.0-7.5. It grows best in nutrient-rich soil with organic matter content. The soil should be deep and loamy, allowing roots to penetrate and grow deep. The plant can tolerate short periods of drought but prefers consistently moist soil.
Cultivation Methods
Stachys bachmannii Gürke is a perennial plant, typically grown in full sun or partial shade. It prefers well-draining soil with a pH of between 6.0-8.0. The plant can be propagated using stem cuttings, division, or by sowing seeds in spring or fall. When planting, ensure to space them 12-18 inches apart, if adequate gaps are not provided the plant may become root-bound and hamper its growth.
Watering Needs
Stachys bachmannii Gürke prefers moderate watering and well-drained soil. The amount of water needed depends on the climatic condition and soil type. Keep the soil consistently moist, but not waterlogged, and water only when the top 1 inch of soil feels dry. A good way of checking the water needs is to prick the soil with a finger up to the second knuckle; if the soil feels dry, water the plant. During hot and dry spells, increase the amount of water you give your plant.
Fertilization
Stachys bachmannii Gürke grows best in fertile soil. Apply fertilizer to the soil in spring to supply the plant with the necessary nutrients to promote growth and flowering. You can apply an all-purpose fertilizer like a 10-10-10, or a natural source like compost or aged manure. Avoid applying fertilizer in the fall when the plant is preparing to go dormant.
Pruning
Deadheading spent blooms promotes the growth of additional flowers and maintains the plant's appearance. Cut back the plant by one-third its height after the first flowering in summer. This will encourage bushier growth, and give the plant a second flush of flowers in the fall. Pruning should be done early in the morning or evening to prevent sun scorching. Avoid pruning the plant during the winter months.
