Hattie the Hen
Deeply Rooted
It needs to be planted in a lot of horse/ cow/ chicken compost as well as kept well watered in hot weather. I would also mulch it well in summer & cover with shade cloth if you are in a hot climate as it is much more likely to try to go to seed. The moment you see a tall phallic stalk (no leaf) cut that off at the base, otherwise it will stop producing young tasty leafy stalks for that year.
Good Luck
Hattie
