Fall Vegetable Planting Guide for Coastal North Carolina

Late July feels too hot to think about gardening, but this is exactly when Eastern North Carolina's fall vegetable garden gets started. Cool-season crops like collards, broccoli, and kale actually taste better when they mature in cool weather, and in the coastal plain, that window opens now, not in September.

This guide uses NC State Extension's planting dates for the coastal plain and adjusts for our stretch of the coast, so you can get seeds and transplants in at the right time instead of guessing.

Why Fall Is the Better Season Here

Spring in the coastal plain heats up fast, and crops like lettuce and spinach bolt (send up a flowering stalk and turn bitter) as soon as temperatures climb. Fall avoids that problem entirely. Vegetables planted in late summer mature during the cooling days of autumn, and North Carolina's mild winters mean many of these crops keep producing well past the first frost (NC State Extension).

Adjusting the Calendar for the Cape Fear Region

NC State Extension's standard fall planting dates are written for the upper coastal plain and lower piedmont. If you garden in New Hanover, Pender, or Brunswick County, plant 7 to 10 days later than those dates, since our stretch of coast holds its heat longer into fall (NC State Extension). The Eastern North Carolina Planting Calendar builds this adjustment into its own dates and is worth bookmarking if you garden here year-round (NC State Extension).

Plant transplants mid-July through mid-August, adjusted about a week later for the coast. Collards tolerate frost and light freezes and hold in the garden through winter, developing their best, mellowest flavor after the first cold snap. Space plants 18 inches apart and give them full sun and nitrogen-rich soil.

A Few Notes on Getting Seeds Up in Late-Summer Heat

Direct-seeded fall crops face a harder start than spring ones. Soil moisture is lower and surface temperatures are higher, so seeds often need to go in one and a half to two times deeper than they would in spring. Heavy clay soil can crust over germinating seed in the heat, which is why lettuce and spinach rows benefit from a light mulch, burlap, or board laid over the row until seedlings break the surface, removed as soon as they do (NC State Extension).

Before planting, clear out spent spring and summer crop residue and till 6 to 8 inches deep. If the spring bed was already fertilized, you likely will not need another full application. Otherwise, work in 1 to 2 pounds of a complete fertilizer like 10-10-10 per 100 square feet of bed space.

✦ Protecting the harvest through frost Most of these crops need little frost protection once established, but a floating row cover on stakes will extend the harvest through hard freezes and protect young seedlings during an early cold snap. Root crops like turnips can be mulched heavily and left in the ground well into winter.

If you leave even a narrow strip of the bed unplanted for a native fall bloomer like aster or goldenrod, you will have something feeding the last pollinators of the season while your greens get established.
