Why You Need to Store Your Seeds Prior to Sprouting Them
A small quantity of seeds grows into a lot of sprouts! Especially leafy sprouts and grasses.
For example, if you grow a quarter cup of alfalfa seeds, you'll get 8 cups of sprouts.
Usually people grow small quantities of seeds, especially if they're growing a few different varieties at once (ex. alfalfa sprouts, broccoli sprouts and radish sprouts).
Because of this, you'll need to store all the seeds that you are not going to sprout.
It's important to store seeds properly, because it affects the germination rate.
What Is the Best Way to Store Seeds?
Keep the seeds in a sealed container or bag in the fridge or freezer, at 60 degrees Fahrenheit or less.
How Long Can I Store Seeds?
Seeds can be stored for one to two years depending on the variety.
The longer they are kept, the lower the germination rate.
Seeds stored a fridge or freezer have a better germination rate than those stored in a pantry or a cupboard.
What’s the Next Step When I Want to Sprout the Seeds?
Take the seeds out of the fridge or freezer, just the quantity of seeds you want to sprout.
Start soaking them in cold water right away.
Seeds do not have any moisture, so they don't need to thaw before soaking.
No worries about freezer burn, either!
What Can I Do if the Germination Rate Is Low After Storage?
You can soak the seeds for longer than the standard soak time.
For example, instead of soaking the seeds for 12 hours, soak them for 24 hours with a water change at 12 hours (these times are a guide, you don't have to be exact).
The longer soak will help trigger the germination process and you should see a better germination rate.
