Why Is My Artichoke Not Coming Back After Winter?

By April, an artichoke plant that is alive should be showing clear signs of regrowth — small green shoots emerging from the crown, new leaves unfurling. If your plant is showing nothing by mid-April while the soil temperature has risen above 10°C, it is probably dead. Before giving up and digging it out, however, a simple test confirms whether the crown is alive and simply very late, or whether it has genuinely died over winter.

How to test the crown

Gently scratch the crown surface with your fingernail or a small tool. A live crown has firm, cream-white tissue below the bark surface and may already show small green growing points at the shoot bases. The tissue smells clean and earthy. A dead crown is uniformly brown throughout when cut, has no distinct tissue layers, is soft or fibrous, and may have an unpleasant rotting smell. If the crown is brown all the way through with no green tissue, the plant has died and should be removed.

Crown rot death

Crown rot is by far the most common cause of artichoke non-return in spring. The plant sat in wet soil over winter and the crown tissue was killed by Pythium, Phytophthora or Sclerotinia rot. The remedy for future plants is improving drainage — see the crown rot guide for the full approach.

Frost death of the crown

Artichoke crowns are hardy to approximately -10°C in well-drained soil. In exceptionally cold winters, or in very exposed positions without any mulch protection, the crown itself can be killed by frost. The dead crown in this case is brown and fibrous but firm — different from the mushy texture of a waterlogged rot. Future plants should be mulched more heavily and sited in a more sheltered position.

Replacing a dead plant

Remove the dead crown completely — do not leave it in the ground as it may harbour pathogens. Improve drainage before replanting. Plant either a new seedling or, better, a rooted offset from a healthy neighbouring plant. Offsets from mature plants establish more quickly than seed-grown plants and often produce their first heads in the same season they are planted.
