Chives are a total superstar in the garden, and not just because they taste amazing on a baked potato. They’re super low-maintenance, packed with nutrients, and—best of all—they can handle chilly winter temperatures like a pro. Even though they’re tough, giving them a little extra TLC before the first frost goes a long way.
Are Chives Winter-Hardy?
Good news: perennial chives are incredibly resilient and can survive temperatures as low as -13°F (-25°C). To get them ready for their winter nap, cut the leaves back to about an inch (2 cm) above the ground in late fall. Once you’ve done that, tuck them in with a protective layer of mulch. You can use:
- Wood chips or mulch
- Fallen leaves
- Evergreen brush
- Straw
If your chives are planted directly in the ground, that’s really all the prep they need!
How to Overwinter Potted Chives
When you’re growing chives in pots, the roots are a bit more vulnerable because they aren’t insulated by the deep earth. They’re still hardy, but they’ll appreciate a little extra warmth. Try wrapping the pot in burlap or frost fleece and moving it close to the side of your house for shelter.
If you’d rather bring them inside, keep in mind that they still need a dormant phase. They’ll do best in a cool spot with plenty of light. Avoid placing them on a windowsill right above a hot radiator! Instead, try these spots:
- A cool hallway or stairwell with a window
- An unheated sunroom or greenhouse
- A garage with a window
Caring for Your Chives During Winter
Believe it or not, chives can actually get thirsty in the winter, especially those in pots. Water them occasionally on days when the ground isn’t frozen. It’s best to do this in the morning so the water has time to soak in before the temperature drops at night. If your chives are in the garden bed, you usually don’t need to worry about extra watering.
One big “don’t”: never fertilize your chives in the winter. Those extra nutrients send the wrong signals, telling the plant to grow when it should be resting. Let them sleep so they can come back stronger in the spring!
