Alfalfa grows well in the St. Paul, Minnesota area and when grown inside so do alfalfa sprouts. You can easily grow them in a jar near a window inside your home and have fresh organic sprouts when you want them.
To grow alfalfa sprouts you need a jar with a lid rim on it. You don’t need the inner part of the lid just the screw on top and something that will work like a screen. You can buy special lids to grow alfalfa sprouts with at a health food store but you can also make do with a piece of cheese cloth or a screen.
Put a teaspoon of alfalfa seeds into your jar and add some water. Let the seeds soak in the water for awhile. Then place the lid with the screen on top of the jar and pour out the water. The screen should catch the seeds and keep them in the jar as the water is pouring out. Some seeds will stick to the sides of the jar but most should stay on the bottom.
Morning and night you should rinse your seeds by adding some water to cover the seeds and pouring the water out. This refreshes the seeds anc keeps them from getting stale and rotting. You can use water from your sink but if you want organic alfalfa sprouts you need to use some water without chemicals or other additive in it. Bottled water may be nastier then the water you get from your sink so check what is in it before you use it.
As your seeds sprout you will see your jar filling up and you will be able to tell when your seeds have sprouted to ther proper size to eat. Rinse them well before you eat them to get the seed husks out.
Growing fresh alfalfa sprouts can be a good way to get fresh greens during the winter when fresh vegetables are harder to get.
