Over-Wintering Tomato Plants: Successes and Failures


Can you keep tomato plants alive all winter? I've tried it for several years, sometimes with success, sometimes with a total failure. Here are my experiences, as well as some advice.

Can you keep tomato plants alive all winter?


Several years ago I began taking cuttings from my tomato plants in the fall, before the first frost. I put the cuttings in jars of water and kept them alive on my kitchen windowsill so I could plant them in the garden in the spring.

You can find all the details in my post on over-wintering tomato plants without a greenhouse.

I kept records for several years on the successes and failures I experienced with my "perennial tomato clones." Did it work? Read on and find out!

This post was updated and rewritten in August 2020.

The First Year: Success!


The first year I took cuttings from both varieties of tomatoes in my garden: Bradley (an heirloom) and Early Girl (a hybrid).

If my experiment worked, hybrid varieties would produce fruit true to type because they are grown from the same plant instead of from seeds. (Hybrid seeds usually don't produce fruit like the parent plant; you never know what you'll get.)

The Early Girl cuttings grew roots like crazy. The Bradley plants grew some very long roots, but not as prolifically.

I lost the Bradley cuttings in January - I think they needed fertilizer or perhaps some comfrey tea or compost tea - but the Early Girl cuttings did very well. They grew tall and leggy - they needed more light, I'm sure.

I potted the Early Girl cuttings in February and planted them in the garden in spring, after all danger of frost had passed.


The results of my multi-year experiment to keep tomato plants alive all winter long. Do they reproduce the next year?


I watered them. I waited for that first red tomato, and waited, and waited. There were flowers, but no fruit.

I was afraid it was because I'd used cuttings but I knew that this experiment should be successful.

But I spoke to other local gardeners and to our county extension agent and found out that no one was getting tomatoes that summer - or many vegetables at all, really.

Was it all the rain we had during the summer? The grasshoppers? Lack of bees? Too hot, too humid? It was a mystery, and we'll probably never really know the cause. It was a strange summer.


The results of my perennial tomato plant experiment.


I've tried for many years to keep tomato plants alive all winter without a greenhouse. Here are the results of my experiments.


When cooler weather arrived, I finally had little green tomatoes, big green tomatoes, orange tomatoes... and finally, delicious red tomatoes! My experiment worked, I had tomatoes from last year's plants!

The Second Year: Failure


This year my cuttings died before December arrived. I wasn't going to let this failure stop me though. I tried again that fall.

The Third Year: Success


In late October I cut a dozen branches from the still-thriving Arkansas Traveler plant growing in a tub in my front yard, and another half dozen from the Mortgage Lifter plants in the garden. Each cutting was about ten inches long.

If you know me, you know that I'm not partial to a particular variety of tomato - I'm willing to try them all! After all, gardening - like life - is a big experiment and a series of adventures.

I removed the leaves from the bottom of the cuttings and stuck them in glass jars, six to a jar. The cuttings lived on my kitchen windowsill over the winter. I potted them up in January and had nice big transplants in the spring.

I also grew other varieties from seed as usual, and I always end up buying a plant of a new variety at the garden center or feed store too. I just can't resist.

The over-wintered plants really give me a jump on the season though. These large, strong transplants are ready to go into the garden as early as the weather allows in spring.

The Fourth Year: Failure


The cuttings died early in the winter. The culprit: spider mites that were evidently on one of the herb plants already in my kitchen windowsill when I brought the tomato cuttings indoors.


Watch for spider mites and other pests on your cuttings before you bring them indoors for the winter.


I noticed the webs on the leaves of the tomato cuttings as they began dying, but it was too late.

Lesson learned: check the herbs and other potted plants before bringing in tomato cuttings, and check the tomato plants too! A hard shower from the hose will help dislodge insects.

The Fifth Year: Success


I took cuttings early in fall, so that if I had problems (cuttings dying early, for instance), I'd have time to cut more before frost killed the tomato plants in my garden.

I cut suckers from one of the Cherokee purple plants, the Juliet plants (a hybrid), and from my one and only Arkansas Traveler plant.

The Oklahoma weather was crazy that summer. As of October first I'd had exactly three red tomatoes and two handfuls of yellow pear tomatoes. Even the canning entries at our county fair were low that year because no one had a garden bounty of anything.

In the past, I've left the cuttings in water for most of the winter, planting them when the roots were so long and thick that I had no choice. This year I planted them in soil as soon as they had roots, using plastic cups from the grocery store with holes punched in the bottom with a knife, and filled with potting soil.

The cuttings survived the winter and grew well in the garden. There is less worry about the roots adapting to a new environment when you transplant them into pots right away, so I plan to continue doing that.

In conclusion


So yes, my experiment was successful in the long run - more than 50% successful over the years.

It would have been a better experiment if I'd attempted to over-winter the same varieties each winter, but weather is fickle and sometimes my best performing varieties the year before failed utterly the following year.

And while not every year was successful, I proved that it can be done, that you can over-winter your tomato plants by taking cuttings, rooting them, and nurturing them on a sunny windowsill until spring arrives once again.

I recommend starting tomatoes from seed in the spring too though, because I always like to have a Plan B. A summer without fresh tomatoes is unacceptable, in my opinion!

These big, healthy plants that successfully over-winter are easy to harden off and plant in the garden after all danger of frost has passed. (You can find out the approximate date of your last frost - and your average first frost in autumn too - by entering your zip code in this frost calculator from Dave's Garden.)

Will you try keeping your tomato plants alive all winter?

  1. I'm going to try this. We also had such a terrible tomoto year, but with the cooler temps we're getting some fruit again. I can't wait to see what happens for you next year.

  2. Thank you, Angi. This terrible tomato year is a mystery, isn't it? I hope you'll give this a try, and let me know your results.

  3. I've so gotta try this! Out of the 5 varieties we planted, 2 did great. Unfortunately, I don't know what they were (1 was given to me by a stranger at a store), so I can't go buy them again. Problem solved - cuttings!

  4. That's perfect, Nikki! Take lots of cuttings since you can't replace these plants.

  5. I wish I would have read this earlier, I have to try this.

  6. File it away for next year, Kathy!

  7. That is awesome and when I finally get a plant that is disease resistant I will do just that! I have had a hard time for the past few years with some dreadful blight and I need to get out there and find a better plant. Once I do, I'll be unstoppable in my propagating! Very clever!

  8. Wishing you luck finding a disease-resistant tomato variety. Do you rotate where you plant them each year?

    Does this have anything to do with the fact that your tomatoes might be 'determinate' and not 'indeterminate'? We live in eastern WA and I had a ton of tomatoes this year. We used compost from the compost bin when we planted them and I didn't have to even fertilize this year. It was the year of the tomato, cucumbers, peppers!

  10. Hi Janice, I grow an indeterminate variety, so I don't think that was the reason. It was evidently just some weird regional thing this year. I hope next year is better!

  11. Now you have me excited to try this next year, as the frost has been here for a couple of weeks..I once had a volunteer tomato that was more frost resistant and when I brought the ripening fruit into the house it ripened perfectly and lasted longer. What I would give to know what that beauty was!!

  12. Janice, I'd love to know what kind that tomato was too. This would be a great way to keep an unknown variety going.

  13. Clever idea! Thanks for sharing it on Tuesday Greens!

  14. I'm heading outside to take some cutting right now! Here in Calif.we haven't had a frost yet so my Big Boy plant is still giving us a few tomatoes! Thanks for the great posts!I'll be a follower! I "garden" at www.theradishpatch.com and I'll share your posts! Thanks,Donna

  15. I have been doing this for a few years. It is a great way to get tomato plants to fruit earlier. I have found in my garden that overwintered cuttings like this will set fruit about 2 months earlier than seed grown plants.

    Thank you, Damo. Great observation; I hadn't noticed.

  17. You don't give up until you find a successful method. The only thing I've had success in overwintering is geranium plants. We have lots of winter frost, so I've tried several methods to keep them alive in our town condo. Like you, some years and methods were a success, and some were failures. - Margy

  18. This is completely blowing my mind. I had NO idea you could take cuttings from tomato plants, nor that you could overwinter them! This could be great for me...I don't have a good indoor seed starting set up so I end up buying tomato starts in particular. I love a particular variety that is hard to find locally, so I might be able to try this method and save some stress (and money)! If it fails, well, all my indoor tomato starting ventures usually do so this would be nothing lost. THANK YOU!!

    1. I'm so glad, Rachael - I love opening windows of possibility to others! You have the same mindset that I do: "if it doesn't work, I haven't lost anything... and if it works, I'm so far ahead!" I hope you are successful and can keep that special variety alive all winter.
