Know before you buy
Alfalfa is a powerhouse for soil health because it is a perennial legume that fixes nitrogen and features a deep taproot. This combination actively enriches soil fertility while breaking up compacted earth to improve aeration.
For the best establishment, sow your alfalfa seeds in either early spring or late fall. These windows allow the plants to take advantage of cooler temperatures and consistent moisture.
Yes, this variety is highly versatile. Beyond soil building, it is an excellent source of protein and minerals, making it a popular choice for forage or as a nutrient-dense addition to your compost pile.
Because it is a perennial, alfalfa will return year after year rather than dying off at the end of the season. It is a great choice for permanent garden beds or areas where you want long-term soil structure improvement without needing to replant annually.
Absolutely. Alfalfa is known for its reliable regrowth, meaning it will continue to thrive and produce biomass even after you cut it for mulch or allow it to be grazed.
