French tarragon - some questions.........
I have a French tarragon plant that is 3 years old and was beautiful until about a month ago. It started turning brown. It still puts out green shoots but about 75% of the plant is brown and crunchy. I read on the web in 2 articles that tarragon will turn brown in mid-season (???) and if cut back it will green up again.
Anyone heard of this?? I usually leave the plant outside over winter but want to try to 'save' this plant - any ideas??
