Best Vegetables To Plant In December In North Carolina

North Carolina’s December climate supports root vegetables that grow slowly through winter’s shorter days. If you are looking for the best vegetables to plant in December in North Carolina, you have come to the right place. This guide covers cold-hardy crops that thrive in the state’s mild winter zones, from the mountains to the coast.

December might seem late for planting, but North Carolina’s USDA hardiness zones (6a to 8a) allow for a surprising range of winter vegetables. The key is choosing varieties that can handle frost and slow growth. Below, you will find a practical list of what to sow now for a spring harvest.

This heading covers the core crops that perform well when planted in late fall. These vegetables are frost-tolerant and benefit from cold stratification or cool soil temperatures. Let’s break them down by category.

Root Vegetables For December Planting

Root crops are ideal for December because they store energy underground. They can survive light freezes and even improve in flavor after a frost.

Carrots: Choose short-season varieties like ‘Nantes’ or ‘Danvers’. Plant seeds ½ inch deep in loose, well-drained soil. They will germinate slowly but grow steadily through winter.
Beets: ‘Detroit Dark Red’ and ‘Golden’ beets work well. Soak seeds overnight before planting to speed germination. Thin seedlings to 3 inches apart.
Radishes: Fast-growing radishes like ‘Cherry Belle’ mature in 25-30 days. Plant them in succession every two weeks for continuous harvest.
Turnips: ‘Purple Top White Globe’ is a classic. Both roots and greens are edible. Plant seeds ¼ inch deep and keep soil moist.
Parsnips: These need a long growing season but can be planted in December for a late spring harvest. They taste sweeter after frost.

Leafy Greens That Tolerate Cold

Leafy greens are some of the easiest vegetables to plant in December. They grow slowly but provide fresh salads by late winter.

Kale: ‘Winterbor’ and ‘Lacinato’ are extremely cold-hardy. Harvest outer leaves as needed. Frost improves their sweetness.
Spinach: ‘Bloomsdale’ and ‘Space’ varieties survive down to 20°F. Plant seeds 1 inch apart in rows 12 inches apart.
Lettuce: Romaine and butterhead types do better than loose-leaf in cold. Use row covers for extra protection.
Swiss Chard: ‘Bright Lights’ adds color to the garden. It can handle light frosts and regrows after cutting.
Arugula: This peppery green grows quickly. Plant seeds every 3 weeks for a steady supply.

Alliums For Spring Harvest

Onions, garlic, and leeks are planted in December for a summer harvest. They need cold temperatures to form bulbs.

Garlic: Plant individual cloves 2 inches deep, pointed end up. Space them 6 inches apart. Mulch heavily with straw.
Onions: Use sets or transplants. ‘Texas SuperSweet’ and ‘Red Creole’ work well. Plant 1 inch deep and 4 inches apart.
Leeks: Start seeds indoors or plant direct. They need a long, cool growing season. Hill soil around stems for white shafts.
Shallots: Plant bulbs 1 inch deep in full sun. They multiply underground and are ready by early summer.

Brassicas For Winter Gardens

Broccoli, cabbage, and cauliflower can be planted in December in warmer parts of North Carolina. They need protection from hard freezes.

Broccoli: ‘Waltham 29’ and ‘Green Magic’ are cold-tolerant. Space plants 18 inches apart. Harvest heads before they flower.
Cabbage: ‘January King’ is a historic variety that survives winter. Plant seedlings 12 inches apart in rich soil.
Cauliflower: ‘Snow Crown’ matures in 50-60 days. Blanch heads by tying leaves over them.
Brussels Sprouts: These need a long season. Plant in December for a spring harvest. They taste best after a frost.

Herbs That Grow In Cool Weather

Some herbs thrive in December’s cool temperatures. They add flavor to winter meals and are easy to grow.

Cilantro: Plant seeds directly in the ground. It bolts quickly in warm weather, so winter is ideal.
Parsley: Flat-leaf and curly types both grow slowly. Soak seeds overnight before planting.
Chives: Divide existing clumps or plant seeds. They die back in hard freezes but regrow in spring.
Thyme: This perennial herb survives winter with minimal care. Plant it in well-drained soil.
Mint: Invasive but useful. Plant in containers to control spread. It dies back in cold but returns.

How To Prepare Your December Garden Bed

Before planting, you need to set up your garden for success. December soil can be cold and wet, so proper preparation is crucial.

Test And Amend Soil

Start by testing your soil pH. Most winter vegetables prefer a pH between 6.0 and 7.0. Add lime if needed. Mix in compost or aged manure to improve drainage and nutrients. Avoid fresh manure, which can burn roots.

Choose The Right Location

Select a spot that gets at least 6 hours of sunlight daily. South-facing slopes are warmer. Avoid low areas where frost settles. Raised beds warm up faster and drain better in winter.

Use Row Covers And Mulch

Frost cloth or floating row covers protect plants from hard freezes. They add 4-8°F of warmth. Mulch with straw, leaves, or pine needles to insulate soil. Apply 2-4 inches around plants after they are established.

Watering In December

Water less frequently in winter. Check soil moisture 2 inches deep. If it feels dry, water deeply in the morning. Overwatering can cause rot in cold soil. Drip irrigation is best to keep foliage dry.

Regional Tips For North Carolina

North Carolina has three main growing regions: mountains, piedmont, and coastal plain. Each has unique challenges for December planting.

Mountain Region (Zones 6A-6b)

Higher elevations get harder freezes. Focus on the most cold-hardy crops like kale, garlic, and parsnips. Use heavy mulch and cold frames. Plant in raised beds to avoid waterlogged soil. Consider starting seeds indoors for transplanting in late winter.

Piedmont Region (Zones 7A-7b)

This area has milder winters. You can plant a wider range of vegetables, including broccoli, cabbage, and lettuce. Row covers are still useful for sudden cold snaps. Soil temperatures are often above 40°F, which allows for slow germination.

Coastal Plain Region (Zones 8A-8b)

The coast has the warmest winters. You can plant almost all the vegetables listed above. Watch for heavy rain and poor drainage. Use sandy soil amendments to improve water retention. Frost is rare but can occur in January.

Step-By-Step Planting Guide For December

Follow these steps to ensure your winter garden thrives. Each step is simple and actionable.

Clear the bed: Remove old plants and weeds. Loosen soil to 12 inches deep.
Add compost: Mix in 2-3 inches of organic matter. Rake the surface smooth.
Check seed depth: Most seeds need to be planted 2-3 times their diameter deep. Follow packet instructions.
Water gently: Use a fine spray to avoid washing seeds away. Keep soil consistently moist until germination.
Label rows: Use plant markers to remember what you planted. December growth is slow, so labels help.
Apply mulch: After seedlings emerge, add a thin layer of straw or leaves around them.
Monitor weather: Cover plants if temperatures drop below 25°F. Remove covers during sunny days.
Thin seedlings: Once plants have 2-3 true leaves, thin them to proper spacing. Crowding reduces yields.
Fertilize lightly: Use a balanced liquid fertilizer every 4 weeks. Avoid high-nitrogen formulas that encourage leafy growth.
Harvest regularly: Pick outer leaves of greens and small roots to encourage continued growth.

Common Mistakes To Avoid

Even experienced gardeners make errors in winter planting. Here are pitfalls to watch for.

Planting too deep: Cold soil slows germination. Plant seeds at the shallow end of the recommended depth.
Overwatering: Wet soil in cold weather causes root rot. Water only when the top inch is dry.
Ignoring frost dates: Check your local first frost date. Some crops need protection earlier than others.
Skipping soil prep: Compacted soil prevents root growth. Always loosen and amend before planting.
Using old seeds: Seed viability drops after a year. Buy fresh seeds for best germination rates.
Not hardening off transplants: If you start seeds indoors, acclimate them to outdoor conditions over 5-7 days.

Harvesting Your December-Planted Vegetables

Most vegetables planted in December will be ready in late winter or early spring. Here is a rough timeline.

Radishes: 25-30 days after planting.
Spinach and arugula: 40-50 days.
Kale and Swiss chard: 50-60 days for baby leaves.
Carrots and beets: 60-80 days.
Garlic and onions: Late spring to early summer.
Broccoli and cabbage: 70-90 days.

Harvest in the morning when vegetables are crisp. Use a sharp knife or scissors to avoid damaging plants. Store root vegetables in a cool, dark place. Greens keep best in the refrigerator with a damp paper towel.
