When To Plant Collards In South Carolina
Greetings From South Carolina

Collards (Brassica oleracea) are among the most favored garden vegetables in the South, particularly in South Carolina. 

However, planting collard greens is more challenging because they cannot survive frost or cold weather under 50 degrees Fahrenheit. You must choose the right time; they will die if you plant them outside too early in the spring. And your collard greens won’t give you a generous harvest if you plant them too late. 

So, when to plant collards in South Carolina? You can grow collards in South Carolina most of the year. Collards are a cool-season vegetable best grown in July and August for a fall crop. Fall collards often persist throughout the cold during mild winters to produce the next spring abundantly.

When To Plant Collards In South Carolina?

The collard is a cool-season vegetable that should be planted during early spring or fall. It is suggested to plant collard in midsummer or early spring for direct seed. And for transplanting, start in early spring or late summer. And generally, matured collard plants resist frosts and light to medium freezes.

Even though collards thrive in warm climates compared to other cabbage family members, they are still regarded as cool-season crops. They typically grow better in early spring and fall at 60 to 65 degrees Fahrenheit.

Direct Seeding

If you choose direct seeding, start planting in the late summer for a fall harvest for optimum results since the soil is much warmer. I also recommend you pick seeds that haven’t been treated with insecticide or fungicide.

Tips For Growing Collard With Direct Seedlings In South Carolina:

  • Keep your soil moist when seedlings start growing. 
  • Place your collard seed in moist soil, generally 0.25 to 0.75 inches (0.64 to 1.91 cm) deep.
  • You can add water if your soil needs to be moist enough to improve seeds’ germination.
  • Seeds planted deeper than 1 inch (2.54 cm) likely will not germinate, according to Clemson University.
  • Planting collard in high temperatures promotes fungal disease and insect pests.
  • On the other hand, growing collard in cool temperatures or even in light frost helps improve flavor and produce the most flavorful leaves.
  • Soil requirements:
    • Collards grow well in various soils with a pH of 6.0 to 6.5.
    • For better yields, use heavier loamy soils.
    • For early spring crops, choose lighter, well-drained, and sandy soils.
    • Ensure that your soil is well-drained and rich in organic matter.
  • Watering Requirements:
    • If your collards’ eaves become wilted and limp, it is a sign that your soil moisture is insufficient. I suggest you water your soil to provide constant moisture to your collards.
    • The best time to water plants is early in the day, allowing the leaves to dry before sundown and keeping your plants healthy.
    • Mulching will help you conserve water and reduce weeds.

    • Flash is typically a dark-green-leaved collard with vigor, high uniformity, and exceptional yields.
  • Open-Pollinated Varieties: Open-pollinated varieties are collards that, if adequately separated from other varieties in the same plant species, will deliver seed that is genetically “true to type,” which means the seed will grow in a plant similar to the parent.
    • Vates is one of the most popular types of collard as it produces superior yield, bolt-resistance, and uniformity.
    • Champion: Champion derived from Vates; however, it is slower to uniform and bolt.
