- Species and varieties: Alfalfa (Medicago sativa) is a perennial flowering plant in the legume family Fabaceae. It is cultivated as an important forage crop in many countries around the world. There are several varieties of alfalfa, including those bred for specific climates and soil types.
- Hybrid or heirloom: Alfalfa sprouting seeds are typically heirloom varieties, meaning they are open-pollinated and have been passed down through generations without genetic modification. This ensures that the seeds produce plants with consistent traits.
- Pruning and training: Alfalfa does not require pruning or training. However, regular harvesting of the sprouts is necessary to encourage continuous growth. For sprouting purposes, seeds should be rinsed and drained daily to prevent mold and ensure healthy growth.
- Fertilization needs: Alfalfa is a nitrogen-fixing plant, meaning it can convert atmospheric nitrogen into a form usable by plants. This reduces the need for nitrogen fertilizers. However, it may benefit from phosphorus and potassium fertilizers, especially in nutrient-poor soils. Organic compost or well-rotted manure can also be used to improve soil fertility.
- Hardiness zones: Alfalfa is suitable for USDA hardiness zones 3 through 9. It can tolerate a wide range of temperatures but performs best in regions with moderate climates.
- Climate requirements: Alfalfa requires a sunny location with well-drained soil. It thrives in areas with moderate rainfall and can tolerate drought conditions once established. The ideal temperature range for growing alfalfa is between 60°F and 80°F (15°C to 27°C).
