You can grow collards by planting them at the right time and giving them the right conditions to thrive.
If you’ve ever wondered how do you grow collards, the good news is that they’re one of the easiest leafy greens to grow in a home garden.
They’re hardy, productive, and forgiving, which makes them perfect for beginners and seasoned gardeners alike.
In this post, we’ll walk through exactly how do you grow collards, from planting to harvest, so you can enjoy fresh greens straight from your garden.
Let’s dig in.
How Do You Grow Collards: The Basics
When you grow collards, you’re growing a cool-season crop that loves rich soil and plenty of sunshine.
Collards are part of the brassica family, which includes cabbage, kale, and broccoli, so they share similar growing needs.
The key to growing collards successfully is timing, soil preparation, and consistent care.
Here’s how do you grow collards step by step:
1. Start With the Right Timing
Collards grow best in cool weather, so you’ll want to plant them in early spring or late summer for a fall harvest.
If you plant collards in the heat of summer, they tend to bolt and turn bitter quickly.
For a spring crop, sow seeds about 3 to 4 weeks before your last frost date.
For a fall crop, plant collards about 6 to 8 weeks before your first fall frost.
In warmer climates, growing collards in fall and winter works beautifully since they actually taste sweeter after a light frost.
2. Choose the Right Spot and Soil
Collards need full sun, which means at least 6 hours of direct sunlight each day.
They also need well-draining soil that’s rich in organic matter.
Before planting, work in some compost or aged manure to give your collards a nutrient boost.
The ideal soil pH for growing collards is between 6.0 and 6.8.
If your soil is heavy clay, consider planting in raised beds to improve drainage.
3. Plant Seeds or Transplants
You can grow collards from seeds or transplants, depending on your preference.
If starting from seed, sow them about 1/2 inch deep and 2 to 3 inches apart.
Once seedlings reach 3 to 4 inches tall, thin them to about 12 to 18 inches apart so they have room to spread.
If you’re using transplants, space them 12 to 18 inches apart in rows that are 2 to 3 feet apart.
4. Water and Feed Regularly
Collards need consistent moisture to grow tender, flavorful leaves.
Water them deeply once or twice a week, aiming for about 1 to 1.5 inches of water per week.
Mulching around your collards helps retain moisture and keeps weeds down.
Feed your collards with a nitrogen-rich fertilizer every 3 to 4 weeks to encourage leafy growth.
5. Watch for Pests and Diseases
Like other brassicas, collards can attract cabbage worms, aphids, and flea beetles.
Row covers can help protect your collards from these pests without using chemicals.
Keep an eye out for signs of disease like yellowing leaves or powdery mildew, and remove affected plants promptly.
How Do You Grow Collards in Containers?
If you don’t have garden space, you can still grow collards in containers.
Choose a pot that’s at least 12 inches deep and wide, and fill it with quality potting mix.
Container-grown collards need more frequent watering since they dry out faster.
Place your containers where they get plenty of sun, and feed them every couple of weeks.
You can grow collards in containers year-round if you move them indoors during extreme weather.
When and How to Harvest Collards
Knowing when to harvest is just as important as knowing how do you grow collards.
You can start harvesting collards when the plants have at least 4 to 6 mature leaves.
Pick the outer leaves first, leaving the inner ones to continue growing.
This method, called cut-and-come-again, lets you harvest collards over several weeks or even months.
For the best flavor, harvest collards in the morning after the dew has dried.
So, How Do You Grow Collards?
You can grow collards by planting them in cool weather, giving them rich soil, plenty of sun, and consistent moisture.
Whether you grow collards in a garden bed or a container, they’re a rewarding crop that keeps on giving.
With a little patience and care, you’ll be harvesting fresh, tender collards in no time.
So go ahead and give growing collards a try, and enjoy the taste of homegrown greens all season long.
