|Look at that rich color left from Fiddleheads!|
I don't know why I didn't think of it before learning it from Marisa at FoodinJars.com , but one should ALWAYS save their blanching water. It provides a nutritious drink for your plants.
From blanching my fiddle heads for 3 pints of pickled asparagus, I yielded two quarts of healthy nutritious water for my plants.
I know my Hibiscus and Orchid are thanking me!
