You can pressure can celery in about 30 minutes for pint jars and roughly 40 minutes for quart jars when using a pressure canner at 10 pounds of pressure.
If you’ve been wondering how long do you pressure can celery, the answer depends on your jar size and your altitude.
Celery is a low-acid vegetable, so it absolutely must be processed in a pressure canner rather than a water bath canner.
In this post, we’ll walk through exactly how long to pressure can celery, why pressure canning is the only safe method, and a few tips to keep your canned celery crisp and flavorful.
Let’s get right into it.
How Long Do You Pressure Can Celery?
The short answer is that pressure canning celery takes 30 minutes for pints and 40 minutes for quarts at 10 pounds of pressure.
But that’s only part of the story because altitude changes everything.
Here’s how the time and pressure break down so you can pressure can celery safely no matter where you live.
1. Processing Times for Pint and Quart Jars
When you pressure can celery, the jar size directly affects how long it needs to stay in the canner.
Pint jars need 30 minutes of processing at 10 pounds of pressure.
Quart jars need 40 minutes because the heat has to penetrate a larger volume of food.
Always start your timer only after the canner has reached the correct pressure, not before.
2. Altitude Adjustments Matter
If you live above 1,000 feet, you’ll need to increase the pressure when you pressure can celery.
At 1,001 to 2,000 feet, use 11 pounds of pressure.
At 2,001 to 4,000 feet, use 12 pounds.
Above 4,000 feet, go up to 13 pounds or more depending on your elevation.
The processing time stays the same, but the pressure must rise to keep the temperature high enough to kill harmful bacteria.
3. Why Pressure Canning Is Non-Negotiable
Celery is a low-acid vegetable with a pH above 4.6, which means botulism spores can survive boiling water.
That’s why you can’t safely pressure can celery in a water bath canner.
Only a pressure canner reaches the 240°F needed to destroy those spores.
So when someone asks how long do you pressure can celery, the real answer is that you must pressure can it, period.
Steps to Pressure Can Celery Safely
Knowing how long to pressure can celery is one thing, but the prep work matters just as much.
Here’s how to pressure can celery the right way from start to finish.
1. Wash, Trim, and Cut Your Celery
Start by washing your celery stalks thoroughly under cool running water.
Trim the leaves and the base, then cut the stalks into pieces that fit your jars.
You can leave them in chunks or slice them smaller depending on how you plan to use them later.
2. Pack the Jars and Add Boiling Water
Pack the celery tightly into clean, hot jars, leaving about 1 inch of headspace.
Pour boiling water over the celery, still keeping that 1-inch headspace.
Add 1/2 teaspoon of canning salt per pint or 1 teaspoon per quart if you like.
Run a plastic knife around the inside to release air bubbles, then wipe the rims and seal with lids.
3. Load the Canner and Vent Properly
Place your jars on the rack inside the pressure canner with 2 to 3 inches of hot water in the bottom.
Lock the lid and turn up the heat, letting steam escape steadily for a full 10 minutes before adding the weighted gauge.
Once the gauge jiggles at your target pressure, start your timer for 30 or 40 minutes.
4. Let the Canner Depressurize Naturally
When the time is up, turn off the heat and let the canner cool completely on its own.
Don’t rush this step by removing the weight early.
Wait until the pressure reads zero, then open the lid and let the jars rest for 5 minutes before removing them.
Tips for Better Canned Celery
A few small tweaks can make a big difference when you pressure can celery at home.
Keep these pointers in mind for the best results.
1. Choose Firm, Fresh Stalks
Canned celery softens quite a bit during processing, so start with the crispest stalks you can find.
Avoid celery that’s limp, brown, or past its prime.
Fresher celery holds up better in texture and flavor once it’s canned.
2. Don’t Overpack the Jars
It’s tempting to cram as much celery as possible into each jar, but don’t do it.
Overpacking prevents proper heat circulation, which means your celery might not process safely.
Leave that 1-inch headspace and let the boiling water fill the gaps.
3. Store Jars in a Cool, Dark Place
Once your jars have cooled and sealed, label them with the date.
Store them somewhere cool, dark, and dry for up to 12 to 18 months.
Check the seals before using each jar, and toss any that are unsealed, leaking, or smell off.
So, How Long Do You Pressure Can Celery?
You pressure can celery for 30 minutes in pints and 40 minutes in quarts at 10 pounds of pressure, adjusting the pressure higher if you live above 1,000 feet.
Because celery is a low-acid vegetable, the pressure canner is the only safe way to preserve it, and skipping that step is never worth the risk.
Follow the times, respect the altitude adjustments, and you’ll have shelf-stable celery ready for soups, stews, and casseroles all year long.
Now you know exactly how long do you pressure can celery, so fire up that canner and get to work.
