Description

Tree Medick (*Medicago arborea*) is an evergreen shrub native to the Mediterranean Basin, typically growing between 1 to 2 meters (3.3 to 6.6 feet) in height, with some specimens reaching up to 4 meters (13 feet). It features silvery-white stems that are soft to the touch and trifoliate leaves with obovate leaflets. The plant produces clusters of pale yellow flowers from February to April, followed by coiled seed pods. Tree Medick thrives in dry, rocky habitats with calcareous soils and is known for its nitrogen-fixing capabilities, enriching the soil in which it grows.

✂️🫘 **Methods to Propagate:**
Propagation is typically done through seeds, which should be inoculated with appropriate Rhizobium bacteria to ensure effective nitrogen fixation. Seeds can be sown directly into well-draining soil in a sunny location. Alternatively, propagation can be achieved through semi-hardwood cuttings taken in late summer.

🌞💧 **Sun and Water Requirements:**
Tree Medick requires full sun exposure and prefers well-drained, calcareous soils. It is highly drought-tolerant once established and does not require frequent watering. Overwatering or poorly drained soils can lead to root rot.

🧑‍🌾👩‍🌾 **When to Harvest:**
While not commonly harvested for direct human consumption, Tree Medick can be pruned to provide high-protein forage for livestock, especially during late winter and spring when other forage options may be limited.

Purpose

- **Nitrogen Fixer:** Through symbiosis with Sinorhizobium meliloti bacteria, Tree Medick enriches soil nitrogen content, benefiting surrounding plants.
- **Animal Fodder:** The foliage serves as nutritious forage for livestock, particularly in arid regions where other forage is scarce.
- **Soil Improvement:** Its deep root system enhances soil structure and organic matter content, improving soil fertility.
- **Erosion Control:** The extensive root network stabilizes soil, making it effective for erosion control on slopes and degraded lands.
- **Ornamental:** With its attractive silvery foliage and yellow flowers, Tree Medick is used as an ornamental plant in gardens and landscapes.
