Collards can grow in winter, and that’s one of the best things about this tough, cold-hardy leafy green.
If you’ve been wondering “can collards grow in winter,” the short answer is a resounding yes, as long as you give them the right conditions.
In fact, collards actually taste sweeter after they’ve been kissed by a light frost.
In this post, we’ll dig into why collards grow in winter, how to plant them for a cold-weather harvest, and the best ways to keep them thriving when temperatures drop.
Let’s get growing.
Why Collards Can Grow in Winter
Collards can grow in winter because they’re built for the cold.
Here’s why they handle chilly weather so well.
1. Collards Are Extremely Cold-Hardy
The main reason collards grow in winter is their impressive cold tolerance.
Unlike tender greens such as lettuce or basil, collards can survive temperatures as low as 10°F (-12°C) once they’re established.
That kind of resilience is why gardeners in zones 6 and warmer can grow collards right through the winter with a little protection.
Even in colder zones, collards can grow in winter under cold frames or row covers.
2. Frost Improves the Flavor
Here’s a fun bonus: collards that grow in winter often taste better than summer-grown ones.
When temperatures drop, the plants convert starches into sugars to protect their cells from freezing.
That natural antifreeze makes the leaves sweeter and less bitter.
So when you grow collards in winter, you’re not just getting a harvest, you’re getting a tastier one.
3. Collards Slow Down but Keep Producing
Collards grow in winter at a slower pace, but they don’t stop altogether.
As long as the soil isn’t frozen solid and daytime temps climb above freezing, the plants will keep pushing out new leaves.
You won’t see the rapid growth you’d get in spring, but a steady supply of leaves is still on the menu.
That slow-and-steady growth is exactly why collards can feed you all season long.
How to Grow Collards in Winter
If you want collards to grow in winter, a little planning goes a long way.
Here’s how to set yourself up for success.
1. Time Your Planting Right
For collards to grow in winter, you need to plant them in late summer or early fall.
Aim to get them in the ground about 6 to 8 weeks before your first expected frost.
This gives the plants enough time to establish strong roots and a good leaf canopy before the cold sets in.
If you plant too late, your collards won’t have the size and strength to grow through winter.
2. Choose a Cold-Hardy Variety
Not all collards are created equal when it comes to winter survival.
Look for varieties known for cold tolerance, like ‘Georgia Southern,’ ‘Vates,’ or ‘Champion.’
These types are proven performers when collards grow in winter, and they’ll give you the best chance at a steady harvest.
3. Protect Them From Harsh Freezes
Even though collards grow in winter, they still appreciate a little TLC during hard freezes.
Use row covers, cold frames, or thick mulch to shield the plants and keep the soil from freezing.
On especially cold nights, a floating row cover can make the difference between survival and setback.
Just remember to vent the covers on warm, sunny days so the plants don’t overheat.
4. Water Sparingly but Consistently
Collards growing in winter need less water than they do in summer, but they still need some.
Water deeply when the soil feels dry a couple of inches down, preferably in the morning.
Avoid overwatering, since soggy soil in cold weather can lead to root rot.
The goal is moist, not soaked, so your collards can keep growing through winter without stress.
5. Harvest Leaves From the Outside In
When collards grow in winter, harvest the outer leaves first and let the inner ones keep developing.
This method keeps the plant producing for weeks, sometimes months.
Just snap off the leaves you need, and the plant will keep on giving.
It’s one of the easiest ways to stretch a winter harvest.
Common Mistakes When Growing Collards in Winter
Even tough plants run into trouble, so here’s what to avoid when collards grow in winter.
1. Planting Too Late
If you wait until the first frost is around the corner, your collards won’t have time to settle in.
Late-planted collards struggle to grow in winter because they never built up enough root strength.
Get them in the ground early and you’ll be rewarded.
2. Skipping Protection
Yes, collards grow in winter, but they aren’t invincible.
A sudden deep freeze without a row cover or mulch can damage even the hardiest plants.
A little protection goes a long way toward keeping your winter harvest alive.
3. Overwatering in Cold Soil
Cold, wet soil is a recipe for root problems.
When collards grow in winter, they use less water, so adjust your watering habits accordingly.
Let the soil dry slightly between waterings and you’ll avoid the most common winter growing pitfall.
So, Can Collards Grow in Winter?
Collards can grow in winter, and they often thrive when the weather turns chilly.
With the right planting time, cold-hardy varieties, and a bit of protection, you can enjoy fresh collards straight through the coldest months.
Plus, those frost-kissed leaves taste sweeter than anything you’d pull in summer.
So go ahead and plant a patch this fall, because collards grow in winter better than most greens ever could.
