Carrots are a popular cool season crop that can be grown in many regions. As temperatures drop in fall, some gardeners may be wondering if their carrot crop can be left in the ground over the winter. The short answer is yes, carrots can be successfully stored in the garden bed during winter months. However, there are some important factors to consider before choosing this method.
When is it Appropriate to Leave Carrots in the Ground?
Leaving carrots in the ground over winter is most suitable for areas that experience cold winters with consistent freezing temperatures. The cold helps slow or stop the carrots growth and development. This prevents the carrots from becoming woody or splitting. Areas with moderate winters that thaw and refreeze repeatedly are not ideal candidates for overwintering carrots in the ground.
In addition, heavy rainfall or poorly draining soil can lead to rotting of the carrots over winter. And regions prone to carrot rust fly infestations are better off harvesting carrots. Varieties that are not bred for storage, like coreless types, are also not the best choice for overwintering in the garden.
Timing and Preparation
Preparing your carrot crop for overwintering needs to happen at the right time in fall Wait until after the first couple light frosts, when the carrots become a bit sweeter, but before a hard freeze sets in Once nighttime temperatures are forecast to drop below 24°F, it’s time to take action.
Start by cutting the green tops back, leaving just 1/4 to 1/2 inch of stem. This prevents further growth and nutrient loss from the roots Next, mark or identify the location of the carrots, as they will become buried under mulch Mounding soil over the carrot crowns for insulation is optional.
Mulching Carrots for Winter
The key to successful overwintering of carrots in the garden is providing sufficient insulation with mulch Materials like straw, leaves, or hay work well Spread mulch over the bed at least 12 inches deep and extending 12-18 inches around each plant. Avoid using fresh, wet mulch that could cause rotting. A layer of row cover over the mulch can help hold it in place.
In very cold climates, a heavy snow cover also insulates the carrots buried beneath. Just be sure to mark rows tall enough to be visible above expected snow depths if harvesting before spring. With proper mulching, carrots can withstand freezing air temperatures for extended periods. Underground, the soil temperature stays slightly warmer.
Harvesting and Use
Well mulched carrots can be dug fresh from the garden all winter long as needed. Come spring, be sure to harvest any remaining roots before the ground starts thawing and the greens begin to regrow. Once carrots resume nutrient uptake into the leaves, the roots become bitter, woody, and less crisp.
The harvested carrots can be used right away or kept in cold storage for a few more weeks. Overwintered carrots tend to be sweeter and more flavorful. Enjoy them raw in salads, roasted with other veggies, or added to soups and stews.
While leaving carrots in the ground over winter is not ideal everywhere, gardeners in zones with cold, dry winters can find success using this storage method. Just be sure to select suitable varieties, prep beds properly in fall, and provide adequate winter insulation with mulch. With a little extra care, you can harvest fresh carrots straight from the winter garden.
Best Carrot Varieties for Storage
The first thing you want to do is to make sure you are growing a carrot variety that is listed as good for storage. We love Nantes carrots for eating and have found the bolero (a Nantes variety) carrots taste and store the best.

When to Harvest Carrots
Carrots can be left in the ground until mid-October. In warmer zones carrots can even be overwintered in the ground, by covering them with a thick layer of straw or leaves. I have tried this myself but unfortunately, my carrots rotted. This makes sense as the ground freezes up to 3 feet down here in southern Alberta.
Frost causes carrots to become sweeter as starches turn to sugars, so it can be beneficial to wait until after a few light frosts to do your big carrot harvest.
Harvesting carrots into a bucket of cool water with a splash of vinegar can help to precool carrots and the vinegar can help kill bacteria on the surface of the carrots.
