Cultivation and Care Scabiosa caucasica:
Light Preference and Soil Requirements: Scabiosa caucasica thrives in light, well-drained soils with a neutral pH. It prefers full sun exposure but can tolerate partial shade. Good drainage is crucial for the plant’s growth, as it is intolerant of wet or poorly drained soils, especially during winter. Applying a light, dry mulch like hay/straw or evergreen boughs in winter can provide protection. Additionally, it is not well-suited to high heat and humidity conditions.
Watering: Regular watering is necessary for Scabiosa caucasica, particularly during the hot summer months. The soil should be kept moist but not waterlogged to prevent root rot.
Fertilizer: Scabiosa caucasica generally does not require frequent fertilization. A light application of fertilizer in the spring can help promote flowering.
Deadheading: Removing spent flowers through deadheading encourages the plant to produce more blooms, prolonging the flowering period.
Pests and Diseases: Scabiosa caucasica may be susceptible to pests such as aphids and spider mites, as well as diseases like powdery mildew. Promptly address any signs of pests or diseases to keep the plant healthy.
Winter Protection: In regions with cold winters, providing protection for Scabiosa caucasica is essential. This can be achieved by covering the plant with a burlap sack or other protective material.
Dividing the Plant:
Every 3 to 4 years, dividing the plant is recommended to maintain its health and vigor. To divide the plant, carefully dig it up and use a sharp knife or spade to separate it into several smaller sections, ensuring each section has a few roots. Replant the divisions in a sunny location with well-drained soil.
Pruning the Plant: In spring, pruning the plant back encourages new growth. Remove any dead or damaged branches to maintain its overall health and appearance.
