Alfalfa is a perennial legume known for its trifoliate leaves topped with blue-purple flowers. It belongs to the pea and bean family and is a vital forage crop, serving as a primary food source for livestock. Alfalfa is also a natural source of nitrogen, as it hosts beneficial bacteria capable of fixing nitrogen from the air into the soil. This makes it a valuable plant for improving soil fertility and supporting the growth of other plants.
For livestock, alfalfa is rich in protein and minerals, providing significant energy for cattle and horses.
How to Grow Alfalfa in Containers
Here is the correct method for growing alfalfa in pots or garden containers:
- Before planting, it is important to choose the right time. If you live in a cold climate, plant alfalfa in early spring. If you live in a warm climate, plant it in fall.
- Fill a container with high-quality potting soil and plant each seed at a depth of 1.5 cm.
- Water the alfalfa to encourage sprouting and root development.
- Alfalfa seedlings should appear within 7 to 10 days.
How to Grow Alfalfa in a Glass Jar
Alfalfa can also be grown indoors in a glass jar without soil. Below is the step-by-step method:
- Use one tablespoon of alfalfa seeds, which will produce about one and a half cups of sprouts.
- Rinse the seeds thoroughly using a fine mesh strainer or clean cloth. Only wash the seeds you plan to sprout.
- Place the washed seeds in a clear glass jar with flat sides to allow better air circulation.
- Pour 5 cm of cold water into the jar, ensuring that all seeds are fully covered.
- Cover the jar with a piece of cotton cloth and secure it with a rubber band.
- Soak the seeds for at least 12 hours in a warm, dry place, away from direct sunlight.
- Turn the jar upside down and drain the water through the cloth.
- Rinse the seeds again, drain well, and dry the inside of the jar to prevent root rot.
- Lay the jar on its side, place the seeds back inside, and keep the jar in a warm, dark place, with the opening covered by the cotton cloth.
- Rinse the seeds with lukewarm water every 8 to 12 hours, drying them thoroughly each time. Continue this for 3–4 days, or until the sprouts reach 3.8 to 5.1 cm in length.
- Once the seeds sprout, spread them on a flat plate and expose them to sunlight for about 15 minutes. When they turn green, they are ready to eat and use.
