Artichokes are a rewarding perennial vegetable that thrives with proper winter care. While these plants are hardy in warmer climates, they need extra attention in areas prone to frost. Follow this guide to protect your artichokes and ensure a bountiful harvest next season.
Winter Artichoke Care Basics
Artichokes are native to the Mediterranean, which means they prefer mild winters and well-drained soil. In colder regions, you’ll need to provide extra protection to help them survive the season.
Mulching for Insulation
Mulching is one of the most effective ways to protect your artichoke plants from the cold. Apply a thick layer of organic mulch around the base of the plant to insulate the roots. This helps maintain soil temperature and prevents frost damage.
Pruning and Cleaning
- Remove Dead Leaves: Cut back any yellowed or dead leaves to prevent pests and diseases from overwintering.
- Prune in Late Fall: Trim the plant down to about 12 inches above the ground to encourage healthy regrowth in the spring.
Protecting from Frost
In frost-prone areas, additional protection is essential. Use frost protection products to cover the plants during freezing nights. Ensure the cover doesn’t touch the leaves directly by using stakes or hoops to create a barrier.
Watering Tips
Artichokes require less water during the winter. Keep the soil moist but not soggy, as overwatering can lead to root rot. Ensure the area has good drainage to avoid standing water.
Fertilizing for Spring Growth
Apply a layer of compost or use a balanced fertilizer, such as one from our organic fertilizer collection, to enrich the soil. This prepares the plant for vigorous growth when the weather warms.
Overwintering Artichokes in Cold Climates
- Container Growing: Transfer artichokes into pots and move them to a greenhouse or sheltered area.
- Bury the Crown: In extremely cold areas, dig up the crown and store it in a cool, dry place until spring.
Common Winter Issues and Solutions
- Root Rot: Avoid overwatering and ensure good drainage.
- Pest Infestations: Check for slugs and snails, which can hide under mulch. Use pest control products as needed.
- Frost Damage: Regularly check frost blankets and replace them if damaged.

Mary, you can either cut them or leave them. The most important part is the root crown. Make sure that is covered with a thick mulch, so it does not freeze.
My artichoke plants regrew their leaves after late Fall cutting back. Now we have frost. Shall I cut them back or cover the whole plants with agricultural fleece?
Erika, yes you can cover your crowns with a wheelbarrow and use either leaves or straw.
Using the box technique, could I put my wheelbarrow upside down over the crown, filled with leaves?
Steve, artichokes typically die back in the winter and with proper care over the winter such as heavy mulching to protect from freezing. If they are going in a greenhouse you may need to water them a few times, just so they do not dry out.
