Hi, I have a small (one year old) French tarragon plant in my herb garden. It's on the south side of a trellis fence inhabited by a grape vine. The garden is East-south east facing and fairly well sheltered. Shall I leave the tarragon where it is and protect it with fleece, or shall I pot it up and put it in the mini-greenhouse which I plan to insulate with bubblewrap, or .... what do you suggest?
I did take some cuttings earlier, but they didn't take, as I forgot to instruct the under-gardener in their care when I slipped a disc a few weeks ago!
