Cool Season Vegetable Gardening in Zone 8: What to Plant in NC
When summer heat starts to fade, it’s time to get your vegetable garden ready for another growing season! For gardeners in Zone 8 and across North Carolina, fall is an excellent time to grow cool-season vegetables that thrive in milder temperatures.
Cool-season crops can be planted in both spring and fall, and many can tolerate light frost or continue growing through winter once established.
What Are Cool Season Vegetables?
Cool-season vegetables grow best when temperatures are cooler, making them perfect for the spring and fall garden.
Some favorites for North Carolina gardens include:
- Kale
- Collards
- Lettuce
- Spinach
- Broccoli
- Cabbage
- Carrots
- Radishes
- Turnips
- Mustard greens
- Swiss chard
- Beets
- Peas
These crops are generally more tolerant of cool temperatures than summer vegetables like tomatoes, peppers, and squash.
When Should You Plant?
Timing is especially important for a successful fall vegetable garden. In the NC Piedmont, August is the main planting window for many fall crops, while quicker-growing vegetables such as leafy greens and turnips can be planted into early September.
If you’re planting later in the season, look for quick-maturing varieties or established transplants. Weather varies from year to year, so always consider your local frost dates and the number of days your chosen variety needs to mature.
Prepare Your Garden
Before planting, clean out declining summer vegetables and weeds. Add a layer of compost or other organic matter to improve your soil before planting.
A soil test is also a great way to determine whether your garden needs additional nutrients or lime. NC State recommends testing vegetable garden soil every two to three years.
Don’t Forget to Water
September can still bring plenty of heat to North Carolina, so don’t put the watering can away just yet!
Keep newly planted seeds and transplants consistently moist while they establish. Once plants are established, continue watering as needed based on rainfall and weather conditions.
Mulch can also help maintain soil moisture and keep weeds under control.
Extend Your Growing Season
Many cool-season vegetables can handle colder weather, and some—especially kale, collards, and turnip greens—can survive winter in North Carolina when well established.
When temperatures really begin to drop, use frost cloth, row covers, cold frames, or other season-extending methods to protect your plants. These techniques can help keep your garden producing well into the colder months.
Your Cool-Season Garden Checklist
