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?
In places where winters are cold and stay below freezing, leaving carrots in the ground over the winter works best. Carrots grow more slowly or not at all when it’s cold outside. This prevents the carrots from becoming woody or splitting. Carrots shouldn’t be left in the ground over the winter in places where the winters are mild and the ground repeatedly thaws and freezes.
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
Carrots can survive the winter in the garden as long as they have enough mulch to keep them warm. Straw, leaves, or hay work well as mulch. Spread mulch over the bed at least 12 inches deep and 12 to 18 inches around each plant. Avoid using fresh, wet mulch that could cause rotting. Putting row cover on top of the mulch can help keep it in place.
In places that get very cold, a thick layer of snow also keeps the carrots buried below warm. Just make sure to mark the rows so they can be seen above the expected snow level if you harvest before spring. Carrots can survive freezing air temperatures for long periods of time if they are mulched properly. 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.
You can use the carrots right away or put them in the fridge to keep for a few more weeks. Overwintered carrots tend to be sweeter and more flavorful. You can eat them raw in salads, roast them with other vegetables, or put them in 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.
