How to Overwinter Artichoke Plants in Cold Climates

Introduction

Artichokes can survive freezing winters with proper protection. In Zone 8 (like Kingman, AZ), where temperatures drop below freezing and snow occurs, two reliable methods ensure plants return vigorously in spring.

Protection Methods

• Row Covers: Lightweight, porous fabric (similar to sheer curtains) that allows light and water through while protecting plants down to 5°F below ambient temperature.
• Heavy Mulch: Thick layers of straw or shredded leaves insulate the crown and roots.

Row covers are often preferred for their ease of use and breathability.

Cutting Back

Regardless of the protection method, cut the plants back before winter. This reduces disease risk and makes covering easier.

Conclusion

With either row covers or deep mulch—and a good fall pruning—artichokes will overwinter successfully and produce a crop the following year.
