How to Grow Alfalfa

Purchase alfalfa seeds from a farm and feed supply store, as alfalfa is most commonly grown for feeding farm animals. When possible, select organic seeds for best results. Make sure that you purchase pure alfalfa seeds, as alfalfa is often mixed with other forms of grass.

Choose a piece of land with a slight incline for planting an alfalfa garden, as the plant will not grow well if there is standing water. Alfalfa grows between 2 and 3 feet tall, so plan a vegetable garden accordingly.

Till the land before planting, removing any weeds or debris found in the soil. Because alfalfa takes root rapidly, it does not need to be planted into the ground. Simply sprinkle an even layer of seeds over the earth, and then cover with a light layer of more soil or peat moss.

Use about 1/4 lb. of seeds to plant an area which is 5 feet by 5 feet, sprinkling the seeds evenly. When in doubt, plant extra seeds, as weather conditions and soil quality can decrease the rate of growth. In about 7 to 10 days you should see the sprouts sticking up from the soil. If you feel you have planted too much, you can thin the alfalfa when it reaches 6 to 12 inches.

Plant alfalfa in April and again in August, cutting and harvesting after about 70 days of growth. Because alfalfa is susceptible to weevils, it is important to keep up on organic pest control as your alfalfa grows.
