Seasonal Planting Guide
South Carolina encompasses USDA hardiness zones 7-9, influencing planting dates for various vegetables. For spring crops, gardeners should note the last frost date to safely plant cool-season crops such as lettuce and peas. Cool-season vegetables can typically be planted as early as February in Zone 8, while the planting window extends to March for Zone 7. Here is a brief guide on when to plant some popular vegetables in South Carolina:
Spring crops (e.g., lettuce, spinach, peas): February to April
Summer crops (e.g., tomatoes, peppers, cucumbers): April to June
Fall crops (e.g., kale, broccoli, carrots): July to September
Winter crops (e.g., garlic, onions): October to November
Seed Starting Indoors vs. Outdoors
Vegetables in South Carolina can be started in two ways: indoors or directly outdoors. Starting seeds indoors allows gardeners to get a head start on the growing season, especially for vegetables like tomatoes and peppers that require longer growing periods. Seedlings should be started indoors 6-8 weeks before the last expected frost. Alternatively, vegetables such as carrots and radishes are typically sown directly into the garden because they do not transplant well.
Successive Planting for Continuous Harvest
To achieve a continuous harvest, gardeners can utilize successive planting, spacing out the seeding dates every two to three weeks. This is particularly effective for leafy greens and root vegetables, ensuring that plants can be harvested all year. It's an ideal strategy for small spaces and can provide a lot of harvest from a limited area, making it perfect for small spaces.
