Canning Tomatoes FAQs: Frequently Asked Questions
Q. Must I always remove tomato skins before processing?
No. You can chop tomatoes, cook them, and can them to use in sauces, chili, and soups. You can also chop tomatoes, cook them, and pour them through a colander to remove pulp, skin, and seeds to make tomato juice.
Q. Should I use a water bath canner or a pressure canner to process tomatoes?
A. Tomatoes can be processed safely either way. Tomatoes face two potential dangers when canned at home: bacteria and enzymes that harbor molds and yeasts. The boiling water bath method is safe because boiling water (212ºF) inactivates enzymes. When acid (in the form of lemon juice) is added to fruit, inactivating many bacteria, tomatoes processed in a water bath canner are safely processed. A pressure canner heats to a temperature of 240ºF for safe tomato processing, both inactivating enzymes and destroying bacteria. Added lemon juice isn’t necessary in pressure canner processing because of the higher temperatures.
Q. Can I use a regular pressure cooker to pressure can tomatoes?
A. A regular pressure cooker is not recommended.
Q. Which tomato varieties are the best for canning?

September’s Tomato Tip: How to Extend Your Tomato Harvest
Once fruit has set, a tomato takes about 40-50 days to ripen on the vine.
Although cold weather is approaching (for our northern hemisphere readers), you can take these steps to extend your tomato harvest until frost.
Learn more about harvesting tomatoes, including tips for ripening tomatoes on the vine.
- Reduce watering. If fruit has reached full or nearly full size, cut back on watering to encourage ripening.
- Pick excess fruit. Ripening fruit takes a good deal of energy from leaves. A large crop can slow the process, especially if temperatures are cooling off in the fall. Pick a few of the just-ripening tomatoes (mature green, turning, or pink) to allow the rest to ripen on the vine.
- Shift roots. Pull slightly at the bottom of the plant to shift the roots. The surprise sends the tomato the signal that it’s time to finish up with the fruit on the vine and go to seed.
That’s it for now. See you next month!
Until then, happy gardening!
