I grew tomatoes in my raised bed last year. At the end of the season I removed the plants since they had all dried up. This year, without planting seeds I have a couple of tomato plants that have germinated and are growing. Is it advisable to leave the plants and enjoy the produce or should I remove them? I have other tomato plants that I germinated from seeds that I can replace with. Just trying to figure out if this "wild" tomato plant will be as productive as my seedling that I germinated. I am in the San Francisco / Bay Area

*** Update: This volunteer is growing like a weed. Starting to see flowers and hopefully tomatoes soon **

See picture. It is growing like crazy and taking over a quarter of the raised bed. It has flowers but have not seen any tomatoes. I was told that volunteers don't fruit. Is that true? Recommendations?

    Adding the location to your question would help use give a better answer. I can see from your user profile that you're in Northern California, so I'll answer based on that location.

  • @JStorage What kinds (varieties) of tomatoes did you grow last year? Commented May 22, 2016 at 2:37

    @Shule last year I planted heirloom yellow pear and heirloom beefsteak in that raised bed.

    @JStorage Ah. I think Yellow Pear is one variety that crosses (and reseeds) easily. I seem to have had it happen before, in raised beds. Of course, that could have been coincidence. I'm curious what a cross with a beefsteak would be like. :) Yellow Pear should produce fine reseeded, at least if your plants have enough light and aren't too close together. I'm less sure about the beefsteak. Commented May 23, 2016 at 23:03

    It's probably not a cross. I just think the likelihood is greater with Yellow Pear. That's not to say it's definitely crossed. It should produce fine. Commented May 23, 2016 at 23:05

The answer really depends on how much space you have to grow tomatoes. The reason most people choose to start with tomato seedlings or plants in areas that are not tropical is that the growing season is relatively short. By the time your volunteer tomatoes start to give fruit (about 100+ days after they start growing for a lot of the short-season varieties, which fruit 60+ days out if you buy plants), the season is nearly over. If you are hoping to start harvesting tomatoes mid-season, you are unlikely to be able to do so with your volunteers.

That said, if you have space, you could keep the volunteers and just accept that they will start giving fruit near the end of the season. If you have space for these tomatoes and a few starts from the store, you'll still get good coverage. In my experience, the volunteers tend to be very healthy and sometimes keep producing well after the seedlings I've purchased have stopped.

Do be aware that the tomatoes you get from the volunteers may not resemble the tomatoes you planted last year. Many of the tomatoes we grow are hybrids, and will not grow true to type from seed. If you were growing heirloom varieties, they are more likely to come true to type. If variety is very important to you, that would be another reason to buy new plants rather than going with the volunteers.

    I planted hierloom tomatoes last year so hoping I get the same one's from the volunteers. Let's see since this is the first time I have volunteers

Usually volunteer tomatoes do not grow large enough to bear fruit before it gets cold again. But if you have the space there's no harm in letting it grow. I have tomato plants that come up in the compost every year and they sometimes bear fast enough for me to get a fruit or two.

  • Sometimes they yield pretty good tomatoes. However, don't expect the same kind(s) of tomato you planted last year. All varieties cross pollinate Commented May 5, 2016 at 14:13

Reseeded tomatoes can potentially be a very good thing. In my experience, they are quite drought-tolerant compared to transplants. They are also stronger, and don't require hardening off. There are really only a few problems with this scenario that come to mind:

  • The parent plant might have been a hybrid. So, you might get a different kind of tomato than you had before. This isn't necessarily a bad thing (although some people will try to convince you it definitely is). While F2 hybrids aren't always as desirable as the parent, in my experience, sometimes they're more desirable. I've had both more and less desirable tomatoes come from Husky Cherry Red F1 in the F2 generation. F1 is the first-generation hybrid (if you planted a hybrid, that's what it would have been last year). F2 is what it would be this year. F3 is what it would be next year. And so on.
  • The tomato may have been cross-pollinated by other tomatoes. Although this isn't terribly likely, it happens. In this case, you'll get a brand new F1 hybrid that you may or may not like. It will probably be at least as productive as the most productive parent, however (given the same conditions and amount of time to grow).
  • Reseeded tomatoes are usually in soil where tomatoes had been the year before. This means there may be less nutrients that tomatoes like in the soil. This can result in smaller tomatoes. Adding extra potassium and other nutrients may help them to get larger, if they used a lot the year before. You could transplant them elsewhere or amend the soil to help matters here.
  • Reseeded tomatoes are usually on ground where tomatoes had been the year before. There may be more diseases and/or pests present in that ground as a result. However, your tomato may or may not be at least slightly more acclimated to the growing conditions than one that has never grown in them before (which growing conditions may or may not include pests and diseases).
  • The tomatoes may not be exactly where you want them. You may also have to cull or transplant some of them if there are too many or if they're too close together. You may still want to cage them, too.
  • They may be late-season tomatoes. If your growing season isn't very long, they may not have time to get a good harvest (because you didn't start them in a protected environment early when it was too cold for tomatoes). Early tomatoes should be fine reseeded. Midseason tomatoes may or may not be okay. If they germinate early enough for the number of days you have left in your growing season, you shouldn't have a problem. Giving them extra phosphorus might help them mature faster.

Other than that, I'd say, enjoy your tomatoes. Everything else is probably a pro.

Growing from saved seed is definitely a good idea, as it can help your tomatoes to acclimate to the growing conditions. If they're already acclimated, or used to the conditions, you may not notice a benefit, however.

Early, determinate and/or dwarf indeterminate tomatoes are probably the best kinds to let reseed, I'm guessing. You might consider the following varieties if you want to do it on purpose (squirt the seeds where you want them the year before), provided they actually do stay viable over the winter (not all varieties seem to do that readily):

  • New Big Dwarf
  • Payette
  • McGee
  • Siberian
  • Glacier
  • Stupice
  • Kimberly
  • Alaska Fancy
  • Mountain Princess
  • Taos
  • Legend
  • Siletz
  • Oroma
  • Saucy
  • Gold Nugget
  • Santiam

I wouldn't let late-season tomatoes reseed unless you're experimenting, or unless you have a long season. I would be leery about mid-season tomatoes, too.

To encourage tomato seeds that have overwintered to germinate, you'll need to water them, if the ground is dry. They'll grow a lot sooner if you do that. Tilling up the soil before you water it may also help. This spring (2016), I had some germinate from soil I put in a bucket and watered in early to mid April or so, here in Idaho (but the remaining ones in the ground took a lot longer to germinate). I should note that we've had a warm spring. Our last frost and/or freeze this year was around April 16th or so (I covered the seedling on that last frost).

If you like the idea of reseeding, you might consider growing tomatillos. They can spread a lot of seeds even with just a few fruits (like weeds). They do great reseeded. Ground cherries and other garden berries may also do well.
