when to plant collards in north carolina

As a leading producer of collards in the United States, North Carolina’s climate is cool enough for this crop to thrive in both spring and fall. If you’re planning your own collard greens garden, the best time to start it would be in the fall, around July 15 to September 15, or in the spring, from February 1 to April 30.

Read below for details on when to plant collards in North Carolina.

Best Time to Plant Collards in NC

Collard greens season begins six to eight weeks before the final frost for those who choose to start seeds indoors.


If you prefer to avoid transplanting, however, it’s possible to grow collard greens outside a short while later, three weeks before the last bout of ice and snow arrives. If you worry about cold weather, you don’t have to.


These vegetables will survive freezing conditions outdoors and germinate when temperatures reach 45 to 85 degrees Fahrenheit.

And considering that they require six weeks to grow before transplanting, you can move your seedlings outside after the last frost or two weeks before it.

Spring scheduling aside, though, I must say fall is the ideal growing season for collards, since warmer spring temperatures may turn their leaves bitter. Meanwhile, plants grown for fall harvest will have a sweeter taste after vegetable starches produce more sugar under slight frost exposure.

This is especially true in North Carolina, where most regions fall within hardiness zone 6 to 8b, though some small areas are under zone 5b. In zone 8 and all parts of the state, it’s wise to plant collard green seeds as late-season crops six to eight weeks before the first frost for optimal growth.

As for what month that would be, the estimate is July to September in eastern North Carolina and central North Carolina. For western parts of the state, the timeframe would be June to early August.

In very warm locations, collard greens may survive winter if given protection in the form of frost cloths.

To help you determine the best time to plant collard greens, here are the frost dates for some locations in NC.

How to Plant Collard Greens? Which Cultivars to Use?


1. Planting tips

To direct-sow seeds in the garden, ensure the ground has a pH of 6 to 6.5 and amend poor soil according to the recommendations of your soil test. The general tip is to apply a balanced fertilizer before planting, such as one pound of a 10-10-10 formula for every 100 square feet.

Once the soil’s ready, sow seeds at a depth of ¼ inch with a distance of 15 inches between them. This spacing for collard greens will leave plenty of room for the veggies to grow until full maturity.

Note that in residences with garden beds, there should be 36 to 42 inches between rows, unless you have a multi-row system, in which the spacing may be half that or 18 inches.

To ensure healthy foliage, supplement the soil with nitrogen three to five weeks after germination. Common fertilizers for this purpose are a 21-0-0, 15-0-0, or 16-0-0 formula. Avoid products with herbicides, and use the same nitrogen dressing for transplants three weeks after moving them into the garden.

If you’re growing collards in containers, use pots with drain holes and fill them with a plant mix, like the all-purpose product from Miracle-Gro.

The pots should be three to five gallons in size if you intend to keep collards in them indefinitely. Otherwise, cell trays will suffice before transplanting. Sow two to three seeds per cell for the highest chance of germination. After about two weeks, pick the healthiest collard in each cell to grow and move into your garden.

Last but not least, pick a plot with full sun and give it 1.5 inches of water per week as well.
