When To Plant Collard Greens In Tennessee

The best time to plant collard greens in Tennessee is in early spring for a summer harvest or late summer for a fall and winter harvest.
 
This leafy green loves the cooler weather Tennessee offers in these two windows and it’s one of the easiest crops to grow in the state.
 
If you’ve been wondering when to plant collard greens in Tennessee, the short answer is that collards thrive when temperatures stay between 60°F and 70°F.
 
In this post, we’ll walk through the best planting windows, how Tennessee’s growing zones affect planting collard greens, and some tips for keeping your crop healthy all season.
 
Let’s dig in.
 

When to Plant Collard Greens in Tennessee

Knowing when to plant collard greens in Tennessee depends on which harvest you’re after, and the state gives you two solid windows to work with.
 

1. Early Spring Planting

For a spring crop, plant collard greens in Tennessee from late February through early April.
 
Gardeners in middle and west Tennessee can often start as early as late February because the soil warms up faster there.
 
In east Tennessee, where the mountains keep things cooler, wait until mid-March or even early April.
 
Collards tolerate light frost, so a late cold snap usually won’t wipe out your seedlings.
 

2. Late Summer Planting

The fall planting window is arguably the best time to plant collard greens in Tennessee.
 
Sow seeds from late July through August so the plants mature as temperatures drop in September and October.
 
A fall-planted collard crop often tastes sweeter because cool nights bring out the natural sugars in the leaves.
 
Many Tennessee gardeners harvest collards from these plantings well into December and sometimes beyond.
 

3. Winter Overwintering in Mild Zones

In Tennessee’s milder zones, like around Memphis and Nashville, collard greens planted in fall can overwinter with a little protection.
 
A layer of straw or a floating row cover keeps the worst of the cold off the plants.
 
When you plant collard greens in Tennessee this way, you can often pick leaves all winter long.
 

Tennessee Growing Zones and Collard Greens

Tennessee spans USDA hardiness zones 6a through 8a, and that range matters when you plant collard greens.
 

1. Zone 8a in West Tennessee

West Tennessee sits in zone 7b to 8a, which means mild winters and a longer growing season.
 
Here, you can plant collard greens in Tennessee earlier in spring and later in fall than gardeners in the eastern part of the state.
 

2. Zone 7 in Middle Tennessee

Middle Tennessee falls mostly in zone 7a and 7b, a sweet spot for collards.
 
Both the spring and fall planting windows work beautifully here, and the soil drains well in most spots.
 

3. Zone 6 in East Tennessee

East Tennessee’s higher elevations push it into zone 6a and 6b, so the season is shorter.
 
If you live there, plant collard greens in Tennessee a couple of weeks later in spring and be ready to protect fall crops from early freezes.
 

Tips for Planting Collard Greens in Tennessee

Once you know when to plant collard greens in Tennessee, a few simple habits make the crop thrive.
 

1. Prepare the Soil

Collards like rich, well-drained soil with a pH between 6.0 and 6.8.
 
Mix in compost a few weeks before you plant collard greens so the roots have plenty of nutrients to work with.
 

2. Water Consistently

Give your collards about an inch of water per week, especially during dry spells.
 
Even moisture keeps the leaves tender instead of tough and bitter.
 

3. Space Plants Properly

Thin or transplant seedlings so they sit 18 to 24 inches apart.
 
Good airflow helps prevent the fungal issues that show up when collards are crowded.
 

4. Watch for Pests

Cabbage worms and aphids love collards as much as you do.
 
Check the undersides of leaves often and pick off pests by hand or use row covers to keep them out.
 

5. Harvest from the Bottom Up

Pick the outer leaves first and let the center keep growing.
 
This way, one planting of collard greens in Tennessee keeps feeding you for months.
 

So, When to Plant Collard Greens in Tennessee?

The best time to plant collard greens in Tennessee is early spring for a summer harvest or late summer for a fall and winter harvest.
 
Cool weather is what collards crave, and Tennessee’s two mild seasons serve them perfectly.
 
Whether you garden in zone 6 or zone 8a, you now know when to plant collard greens in Tennessee and how to keep them productive.
 
Get those seeds in the ground during the right window and you’ll be enjoying fresh greens from your own backyard for months.
