Alfalfa Sprouts
Medicago sativa
vegetableAlfalfa sprouts are young, germinated seedlings of the alfalfa plant, harvested just days after sprouting when they are tender and nutrient-dense. They are commonly grown indoors in jars or sprouting trays rather than in soil, making them one of the quickest and easiest vegetables to produce at home. Rich in vitamins, minerals, and enzymes, alfalfa sprouts are a popular health food addition to salads, sandwiches, and Asian cuisine.

Growth Stages
Soaking
6-8 hoursDry alfalfa seeds are submerged in water to initiate germination
Use high-quality sprouting seeds (not agricultural seed). Soak for 6-8 hours in cool water at room temperature (65-75°F). Discard floating seeds and any debris.
Initial Sprouting
1-2 daysTiny white root tails begin to emerge from seeds; seeds appear swollen and alive
Drain soaked seeds completely. Spread in a single layer in sprouting jar, covering with cheesecloth or sprouting lid. Rinse and drain thoroughly 2-3 times daily. Keep in warm location (65-75°F).
Root & Shoot Development
2-3 daysRoots lengthen and first true leaves (cotyledons) emerge; sprouts begin to show green coloration with increased light exposure
Continue rinsing 2-3 times daily. If desired, expose to indirect light for several hours to develop chlorophyll and improve nutritional content. Ensure sprouts stay moist but not waterlogged; drain completely after each rinse.
Leafy Growth
2-3 daysFirst true leaves fully develop, sprouts are bright green (if light-exposed) with visible root systems; texture becomes tender and crisp
Increase light exposure to 4-6 hours per day for maximum chlorophyll and nutrition. Continue rinsing 2-3 times daily. Sprouts are ready to harvest when 1-2 inches long with opened cotyledons.
Harvest
At harvestSprouts are 1-2 inches tall, bright green (if exposed to light), with fully developed root systems and tender leaves
Rinse thoroughly one final time. Drain completely and pat dry with a clean towel. Store in refrigerator in an airtight container or plastic bag with a paper towel to absorb excess moisture.
