Parsnips

Question

I asked a question about my parsnips and your answer was rocky ground, definitely not any rocks or stones at all in the ground. It is a  well manured, raised bed they are in.

Answer 1

If you do not believe that tough soil is the issue, I would have a soil test done. A lack of phosphorous or potassium can affect the roots in a number of ways, among them deformed roots.
