In this post, we’ll walk through how to can collard greens, from picking and prepping to processing and storing.

How Do You Can Collard Greens Safely?

When you can collard greens, safety comes first because greens are a low-acid food.
 
That means you can’t just use a boiling water bath, you need a pressure canner to reach the temperatures required to kill harmful bacteria.
 
Here’s how the process works from start to finish.
 

1. Pick and Wash Your Greens

Start by selecting fresh, tender collard greens.
 
You can can collard greens that are young and crisp, but avoid leaves that are yellowed, wilted, or pest-damaged.
 
Wash them thoroughly in several changes of cold water to remove dirt and grit.
 
Collards tend to hold sand in their folds, so rinse each leaf carefully.
 

2. Blanch the Greens

Blanching is a step many people skip, but it matters when you can collard greens.
 
Bring a large pot of water to a boil, then drop in the greens for about 3 minutes.
 
This softens the leaves, removes bitterness, and helps them pack tightly into jars.
 
After blanching, plunge the greens into ice water to stop the cooking process.
 

3. Pack the Jars

Once your greens are cooled, drain them well.
 
Pack them into clean, hot jars, leaving about 1 inch of headspace.
 
You can can collard greens as whole leaves or chopped, depending on your preference.
 
Add ½ teaspoon of salt per pint or 1 teaspoon per quart if you like, though it’s optional.
 
Then cover the greens with boiling water, still keeping that 1-inch headspace.
 

4. Process in a Pressure Canner

This is the most important part of how you can collard greens.
 
Wipe the jar rims, place the lids and rings on, and load the jars into your pressure canner.
 
Process pints for 70 minutes and quarts for 90 minutes at 11 pounds of pressure (adjusted for altitude).
 
Never rush this step, because under-processed greens can spoil.
 

Tips for Canning Collard Greens at Home

Canning collard greens gets easier once you know a few helpful tricks.
 
These tips will help you get a better result every time you can collard greens.
 

1. Use Fresh Greens Only

The fresher your greens, the better they hold up when you can collard greens.
 
Aim to can them within 24 hours of harvest for the best texture and flavor.
 

2. Don’t Overpack the Jars

It’s tempting to cram in as many greens as possible, but don’t.
 
When you can collard greens, leaving proper headspace allows for expansion and a good seal.
 

3. Keep Everything Clean

Sanitize your jars, lids, and tools before you can collard greens.
 
A clean workspace reduces the risk of contamination and failed seals.
 

4. Check Your Altitude

Pressure canning requires altitude adjustments.
 
If you live above 1,000 feet, you’ll need to increase the pressure when you can collard greens.
 

How Long Do Canned Collard Greens Last?

When you properly can collard greens, they can last up to 12 to 18 months on the shelf.
 
Store your jars in a cool, dark place, and check the seals before using them.
 
Once opened, refrigerate the greens and use them within 3 to 4 days.
 
If you ever see signs of spoilage, like a bad smell or cloudy liquid, toss the jar.
