North Carolina’s September warmth allows for a second planting of vegetables that thrive in the state’s long autumn season. If you are looking for the best vegetables to plant in September in North Carolina, you have come to the right place. This guide will help you fill your garden with cool-season crops that love the mild fall weather.
September in North Carolina is a gardener’s sweet spot. The intense summer heat fades, but the soil stays warm enough for seeds to sprout quickly. You can still harvest well into November or even December, depending on where you live in the state. Let’s get straight into what you should plant now.
Best Vegetables To Plant In September In North Carolina
September planting focuses on vegetables that mature before hard frosts hit. These crops prefer cooler temperatures and shorter daylight hours. They also tend to be more pest-resistant than summer crops.
Leafy Greens For Quick Harvests
Leafy greens are the stars of the fall garden. They grow fast and can handle light frosts, which actually sweetens their flavor.
Lettuce
Lettuce is one of the easiest vegetables to start in September. Choose loose-leaf varieties like Black Seeded Simpson or Red Sails. They mature in 45 to 55 days. Plant seeds directly in the soil, about a quarter-inch deep. Keep the soil moist until seedlings appear, which takes about a week.
Spinach
Spinach loves cool weather. Plant it in early September for a harvest in late October. Varieties like Bloomsdale or Space work well. Sow seeds half an inch deep and two inches apart. Thin seedlings to six inches apart once they grow. Spinach can survive light frosts, so you can pick leaves well into November.
Kale
Kale is a tough crop that thrives in fall. It actually tastes better after a frost. Plant dwarf Siberian or Winterbor varieties. Sow seeds a quarter-inch deep and 12 inches apart. You can start harvesting outer leaves in about 50 days. Kale keeps producing until hard freezes arrive.
Swiss Chard
Swiss chard is colorful and heat-tolerant. It grows well in September because the soil is still warm. Plant seeds one inch deep and eight inches apart. You can harvest leaves in 50 to 60 days. Chard can handle light frosts, making it a reliable fall crop.
Root Vegetables For Storing
Root vegetables are perfect for September planting. They store well and develop better flavor in cool soil.
Carrots
Carrots need loose, sandy soil to grow straight. Plant seeds in early September for a November harvest. Sow seeds a quarter-inch deep and one inch apart. Thin seedlings to three inches apart. Varieties like Nantes or Danvers do well in North Carolina. Water regularly to keep the soil moist.
Beets
Beets grow quickly and can be harvested in 50 to 60 days. Plant seeds one inch deep and two inches apart. Thin seedlings to four inches apart. Varieties like Detroit Dark Red or Golden Beet work great. Beets tolerate light frosts, so you can leave them in the ground longer.
Radishes
Radishes are the fastest crop you can plant. They mature in just 25 to 30 days. Sow seeds half an inch deep and one inch apart. Varieties like Cherry Belle or French Breakfast are reliable. You can plant radishes every two weeks for a continuous harvest.
Turnips
Turnips produce both roots and greens. Plant seeds half an inch deep and four inches apart. Varieties like Purple Top White Globe mature in 50 to 60 days. Harvest roots when they are two to three inches wide. The greens are also edible and taste great sautéed.
Brassicas For Fall Feasts
Brassicas, or cabbage family crops, love cool weather. They need a bit more time to mature but reward you with big harvests.
Broccoli
Broccoli grows well from transplants in September. Set plants 18 inches apart in rows. Varieties like Green Goliath or Waltham 29 do well. Harvest the main head when it is tight and dark green. Side shoots will keep producing after the main head is cut.
Cauliflower
Cauliflower needs consistent moisture and cool temperatures. Plant transplants 18 inches apart. Varieties like Snow Crown or Amazing work. Blanch the heads by tying leaves over them when they are about two inches wide. Harvest when heads are compact and white.
Cabbage
Cabbage is a reliable fall crop. Plant transplants 12 to 18 inches apart. Varieties like Early Jersey Wakefield or Red Acre mature in 60 to 70 days. Harvest heads when they feel firm. Cabbage can handle light frosts, which improves flavor.
Brussels Sprouts
Brussels sprouts need a long growing season, so plant them early in September. Set transplants 24 inches apart. Varieties like Long Island Improved or Jade Cross work well. Harvest sprouts from the bottom of the stalk upward. They taste best after a frost.
Legumes For Soil Health
Legumes fix nitrogen in the soil, which benefits your garden. They also produce tasty pods.
Peas
Snow peas and snap peas are good choices for September. Plant seeds one inch deep and two inches apart. Varieties like Sugar Ann or Oregon Sugar Pod mature in 55 to 65 days. Provide a trellis for climbing varieties. Harvest pods when they are plump but still tender.
Fava Beans
Fava beans are less common but very hardy. Plant seeds one inch deep and six inches apart. They tolerate frost well. Harvest pods when they are full but before they turn brown. Fava beans also improve soil for spring planting.
Alliums For Flavor
Onions and garlic are best planted in fall for a spring harvest. September is the right time to start them.
Garlic
Plant garlic cloves in September for harvest next summer. Break bulbs into individual cloves and plant them two inches deep and six inches apart. Varieties like Chesnok Red or German Extra Hardy do well. Mulch heavily to protect cloves over winter.
Onions
Plant onion sets or transplants in September. Set them one inch deep and four inches apart. Varieties like Red Creole or Texas Super Sweet work for fall. Onions will grow slowly through winter and bulb up in spring.
Herbs For Fresh Flavor
Many herbs grow well in September. They add flavor to meals and attract pollinators.
Cilantro
Cilantro bolts quickly in heat but loves cool weather. Plant seeds a quarter-inch deep and six inches apart. Harvest leaves when plants are six inches tall. Let some plants go to seed for coriander.
Parsley
Parsley is a biennial that grows well in fall. Plant seeds a quarter-inch deep and eight inches apart. Soak seeds overnight before planting to speed germination. Harvest outer leaves as needed.
Dill
Dill grows fast in September. Plant seeds a quarter-inch deep and 12 inches apart. Harvest leaves for fresh use or let plants flower for pickling. Dill self-seeds easily, so you may get volunteers next year.
Planting Tips For September Success
Follow these steps to get the best results from your September garden.
Prepare Your Soil
Remove summer crop debris and weeds. Add two inches of compost or aged manure. Work it into the top six inches of soil. Test soil pH and adjust to 6.0 to 7.0 for most vegetables.
Water Consistently
September can still be warm. Water deeply once or twice a week. Use drip irrigation or soaker hoses to keep leaves dry. This reduces disease risk.
Use Row Covers
Lightweight row covers protect plants from early frosts. They also keep pests like cabbage worms away. Remove covers during the day if temperatures rise above 80°F.
Mulch To Retain Moisture
Apply two inches of straw or shredded leaves around plants. Mulch keeps soil cool and moist. It also suppresses weeds.
Plant In Succession
Stagger plantings every two weeks. This gives you a continuous harvest. For example, plant radishes now and again in two weeks.
Regional Considerations For North Carolina
North Carolina spans multiple climate zones. Your planting dates may vary based on your location.
Coastal Plains
In eastern North Carolina, frost comes later. You can plant into late September. Crops like collards and turnips thrive here. Soil is sandy, so add organic matter to retain moisture.
Piedmont Region
The central part of the state has moderate temperatures. Plant in early September for best results. Use raised beds if your soil is heavy clay. Broccoli and kale do well here.
Mountain Region
Western North Carolina gets frost earlier. Plant in early September or even late August. Use cold frames or row covers to extend the season. Root vegetables like carrots and beets are good choices.
Common Pests And Problems
Fall gardens face fewer pests than summer gardens, but some still appear.
Cabbage Worms
These green caterpillars eat holes in brassica leaves. Handpick them or use Bacillus thuringiensis (Bt). Row covers prevent them from reaching plants.
Aphids
Aphids cluster on new growth. Spray them off with a strong stream of water. Use insecticidal soap if needed.
Slugs And Snails
These pests love cool, moist weather. Set out beer traps or use diatomaceous earth around plants. Remove debris where they hide.
Frost Damage
Watch weather forecasts. Cover plants with row covers or old sheets when frost is expected. Water soil before a frost to release heat overnight.
Harvesting And Storage Tips
Harvest vegetables at the right time for best flavor and storage life.
- Pick leafy greens when leaves are young and tender.
- Harvest root vegetables before the ground freezes.
- Store carrots and beets in damp sand in a cool basement.
- Keep kale and collards in the garden; they improve with frost.
- Pick broccoli heads when they are tight and dark green.
