A dandelion root is strong. I was digging out a couple of dandelions from a vegetable garden bed. The dandelion on the right was showing a few leaves at the surface. That skimpy little root had had its top six inches of root cut off. Yet a little while later, it is able to send up several shoots up through six inches of soil. This means that when you are digging out dandelion roots- if you only get the top six inches of the plant, it may well have the ability to sprout from the remaining root. If you look at the plant on the left, you can see that even a slender root can send up shoots and regrow.
