Drying Dandelion roots to make Dandelion tea.
Dandelions are one of those incredible plants which are often thought of only as an invasive weed, but instead are so much more. They make great companion plants in the garden, their long tap roots bringing up nutrients from below, making them available to other plants. The leaves, flowers & roots (everything but the stem) are all edible and great for the liver.
Better than buying the tea from the supermarket, which can be expensive, it is absolutely simple to make your own, just make sure you don’t pick all of them and I would avoid those which have been mown over, just not sure about the possibility of lead accumulating in them.
