Alfalfa is one of the most often used and valuable plants for animal feed, and has many other uses in the garden too.
Held captive there, the plant releases the nitrogen to other subsequent crops once the plant is tilled in, or the top of the plant is cut to make hay or silage.
One of the benefits of alfalfa in your garden is when it's grown as a cover
crop, the roots can reach an incredible depth in the soil, bringing up
nutrients from way down.
As a leguminous plant, the roots have the special ability to store nitrogen from the air. These are obvious if you look at the roots - they are tiny little nodules.
When the roots rot down after the plant dies, the next crop gets the nitrogen from the soil.
The channels made by the roots also create a highway for the roots of less aggressive plants to follow to find nutrients lower down in the soil column.
These small extruded pellets of shredded and pulverized alfalfa are chock full of the same nutritional benefits of hay, with none of the waste. Use them as a slow release fertilizer around your plants for the best use of this valuable resource.
The blisters that these insects cause can cripple a horse or cow, and leave serious burns on unprotected hands.
Scattering a small amount of the fine seed will give you a great crop of this plant.
Spread it extremely thinly, as although the plants take a while to reach full size, in time each one will be over 60cm (2’) across.
They prefer a gravel soil, and don’t need much added nutrients in the soil, given their ability to glean their own nitrogen right out of the air.
Bees and butterflies relish the nectar of these leguminous plants, no surprise there.
In July when they bloom, the scent of alfalfa will make your head spin, it’s so sweet.
The scent of drying hay is equally as delicious.
In August, you may find alfalfa plants with strange twisted growths on them - these are the seed pods.
Collect them and put them into a paper
bag to dry and soon the pods will open, spilling the seeds into the
bottom of the bag.
Sprinkle them sparingly on top of the snow in the spring to make your own alfalfa meadow.
