You might think it’s impossible to grow fresh, crunchy carrots in the winter, but if you plan and get ready, you can eat homegrown carrots all season. Carrots in the winter can be extra sweet and tasty because it’s cold outside. They’re also great because they give you garden-fresh food when other crops aren’t available. We’ll talk about everything you need to know to grow carrots successfully in the winter in this complete guide.
Choosing the Right Carrot Varieties
The first step is selecting carrot varieties that can withstand colder temperatures and mature before the harshest part of winter. Some excellent winter carrot options include
-
Napoli – An heirloom variety known for its cold hardiness. It has a sweet, tender root that intensifies in flavor through the winter.
-
Danvers is a versatile, tapered carrot that does well in cool weather. Its inside is orange and it can handle heavy soils.
-
Merida – Specifically bred for winter growing. It has long, slender roots with a crisp, sweet taste.
-
Mokum is an extra-early variety that can be picked 45 days after planting. Perfect for areas with a shorter growing season.
-
Purple Dragon – A unique, purple-skinned winter carrot with a bright orange interior. Adds color and nutrition to winter meals.
Opt for fast-maturing varieties in areas with shorter seasons. Slower-growing cultivars can be chosen for cooler regions with longer frost-free periods.
Preparing the Garden Bed
Carrots need loose, nutrient-rich soil to thrive. Before sowing:
-
Loosen the soil and mix in compost or well-rotted manure
-
Remove any rocks or debris that could obstruct the carrot roots
-
Consider building raised beds which warm faster in winter and provide better drainage
-
Ensure the soil pH is between 6.0-6.8
-
Plan on sowing seeds 6-8 weeks before your first expected frost
Proper spacing is also key – sow seeds 2 inches apart in rows 12-18 inches apart. This prevents overcrowding while allowing room for growth.
Protecting Carrots Through Winter
Once planted, carrots need protection from harsh winter conditions:
-
Cover beds with insulating materials like straw, leaves, or pine needles
-
Use row covers, cold frames, or low tunnels to trap heat and protect from frost
-
Water soil regularly if not frozen to keep plants hydrated
-
Mulch heavily around carrot roots for added insulation
-
On sunny yet cool days, vent row covers to prevent overheating
-
Harvest carrots as needed, leaving others protected underground
Winter Care and Maintenance
Continue monitoring and caring for your winter carrots:
-
Check for pest or disease problems and remedy issues promptly
-
Weed carefully to avoid disturbing carrot roots
-
Replenish mulch as needed if it becomes thin or blown away
-
Monitor soil moisture and water lightly during winter thaws
-
Vent cold frames on warm days to allow air circulation
With attentive care, your carrots will continue slowly growing through the winter. Timely harvesting is the last critical step.
Harvesting Winter Carrots
-
Begin harvesting carrots once the weather cools and the roots have sized up
-
Flavor improves after exposure to a few light frosts
-
Use a digging fork for harvesting rather than pulling carrots up
-
Remove row covers temporarily on harvest days to access carrots easier
-
Select individual carrots as needed, leaving others to size up more
-
Store freshly harvested carrots in a cold, humid root cellar or the fridge
Enjoying the Fruits of Your Labor
Once harvested, winter carrots make for a delicious addition to:
-
Hearty soups and stews
-
Fresh salads and slaws
-
Roasted vegetable medleys
-
Fermented pickles and relishes
-
Baked in casseroles or mashed as a side dish
Their extra sweetness and novel availability make winter carrots a real treat. With proper care and protection, you can enjoy the fresh crunch of homegrown carrots all winter long. Just choose suitable varieties, prepare your planting bed, shelter your crop from cold conditions, and savor the fruits of your wintertime labors.
Winter Vegetable Garden Protection
The next step is to keep your crop safe during the winter, when heavy snow, ice, and freezes could destroy it. Cold frames and mini hoop tunnels are great ways to offer crop protection. Both are basically small greenhouses, and using them is the equivalent of moving your garden one growing zone south. A cold frame is an open-bottomed box (often wood) supporting a transparent glass or plastic top that admits sunlight. I keep a loose cold frame to deploy around the garden as needed, but my favorite protection for winter carrots is a mini hoop tunnel, which is easy to assemble and inexpensive.
To make a mini hoop tunnel over my carrots, I push the ends of flexible 1⁄2 -inch PVC pipes into the ground on either side of the bed so they form arches to support a cover. I space my “hoops” about 3 feet apart along the length of the bed. Local hardware stores often stock precut 5-foot lengths of PVC; just be sure to buy flexible PVC, not rigid. A 5-foot length of PVC makes a garden bed that is 3 feet wide tall enough so that the cover doesn’t touch the carrot leaves. The pipes are also easy to store when they’re not in use.
I cover the hoops with 3-mil plastic sheeting to create the tunnel. Heavy enough to keep out harsh winds and cold in the dead of winter, the sheeting still lets light through. On warm, sunny winter days, I open up the ends of the tunnel to release excess heat, and close them up again at night. I use bricks or broomsticks to weight the edges of the plastic sheeting so that it doesn’t blow away in strong winds.
This simple system works extremely well. One December, I was actually bitten by a mosquito while harvesting crops inside a mini hoop tunnel! Occasionally, a snail survives a few weeks inside the tunnel, nibbling away at the tops of the roots. I simply trim off that damage before eating the carrots. If insect damage bothers you, or you fear losing your crop to rodents, you can always harvest your frost-sweetened carrots and store them in buckets of damp sand placed in a cellar or other cool, frost-free place.
What do Winter Carrots taste like?
If you have never eaten a freshly harvested winter carrot then you have missed out on one of the sweetest garden treats there is! Growing carrots for winter harvest couldn’t be easier. Carrots are one of the wonders of the winter garden. Cold freezing temperatures change the starches in carrots into sugars! This makes them soooooo delicious!
It’s hard to really give you the full picture of what a fresh winter carrot tastes like. You know that strong underlying “carrot taste” that you get when you are eating most carrots? Well, that strong carrot flavor almost completely disappears and is replaced with a very sweet yummy flavor!
Elliot Coleman describes them as “Candy carrots” in his book Four-Season Harvest

Can carrots grow in 90 degree weather?
Cabbage and cauliflower will germinate at 100°F (37. 8°C), carrots and onions at 95°F (35°C), turnips at 105°F (40. 6°C). But importantly, most varieties of these crops will not thrive if temperatures remain that high, because the plants must go through other growth stages that are more sensitive to heat.
Do carrots grow back every year?
- Biennials: Carrots are biennials, not annuals or perennials.
- First Year: In the first year, carrots focus on growing a large, edible root (the carrot we eat).
- Second Year: The second year, the plant will typically flower and produce seeds.
- Growing New Carrots: To grow new carrots, you would need to plant the seeds produced in the second year, not the original carrot itself.
- Leaving Carrots in the Ground: If you leave a carrot in the ground after the first year, the plant will continue its life cycle and go to seed in the second year, producing a flowering stalk and eventually seeds.
- Regrowing from Stubs: It’s possible to regrow the leafy tops of a carrot by planting the stub end with some greens attached, but this will likely also result in the plant going to seed in the second year.
Can carrots grow in winter?

Will cold weather affect my carrots?
Cold temperatures will sweeten your carrots by converting their starches into sugar, so allow a few light frosts to affect your crop before you taste any roots. The next step is to protect your crop during winter, when severe freezes, snow, and ice threaten to destroy it. Cold frames and mini hoop tunnels are great ways to offer crop protection.
Are winter carrots sweet?
Sweet winter carrots, as he calls them, are harvested in the coldest part of winter. Keeping them in the ground through the cold of winter sweetens the carrots so that they transcend store-bought or even fresh, summer-grown varieties from your garden.
