save those onion roots and grow more onions!
Dandelion: Almost every part of the plant is useful. A beneficial drink can be made from the roasted roots of dandelion. An infusion of raw root is reputed to be good for some liver complaints. Leaves and stems can be chopped into a salad or made into a medicinal tea to ease stiff joints and relieve indigestion. Dandelion wine can be made from the flowers--a gallon of flowers for a gallon of wine.
HYDRANGEAS how to: in late July or August, root branches and grow more hydrangeas!
The next time you have green onions, don't throw away the white ends. Simply submerge them in a glass of water and place them in a sunny window. Your onions will begin to grow almost immediately and can be harvested almost indefinitely. We just use kitchen scissors to cut what we need for meals. I periodically empty out the water, rinse the roots off and give them fresh water.
