Growing fresh, crunchy carrots during the cold winter months may seem impossible, but with some planning and preparation, you can enjoy homegrown carrots all season long. Winter carrots can be extra sweet and tasty due to the colder temperatures and have the added benefit of providing garden-fresh produce when other crops aren’t available. In this comprehensive guide, we’ll cover everything you need to know about successfully growing carrots in winter.

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 – A versatile, tapered carrot that can handle cool weather It has an orange interior and withstands heavy soils

  • Merida – Specifically bred for winter growing. It has long, slender roots with a crisp, sweet taste.

  • Mokum – An extra-early variety, ready for harvest just 45 days after sowing. 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 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. 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. For a 3-foot-wide garden bed, a 5-foot length of PVC creates just enough height to keep the cover from touching the carrot fronds, and the pipes are easy to store when not in use.

I cover the hoops with 3-mil plastic sheeting to create the tunnel. The sheeting is heavy enough to keep out fierce winds and cold during the depths of winter, while still admitting sunlight. 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 weight the edges of the sheeting with bricks or by wrapping them around broomsticks to keep the plastic from whipping up in high 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.

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?

AI Overview
  • 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.
