Hi Charles. Happy New Year & congrats to you & Steph on the book award! 🙂
I propagate parsley by leaving the plants to self-seed in a corner of my allotment. Infinitely more efficient than sowing each year. Do you think this would also work with coriander cilantro? On a visit to Riverford, I was told they overwinter coriander in their unheated poly tunnel. But I think it would then bolt early on. I would appreciate your thoughts.
