I planted tomatoes this past year. When they were finished, I removed the plants, but now I see I have some tiny tomato plants popping up in the same area. Can I try to harvest these plants, and will they produce?
It is likely that they will not be the same plant type as the parent plant if you had hybrid tomato plants.
Only Heirlooms will the seeds be the same as the parent plant.
Depending on your growing zone you may or may not have time to grow the plants to a producing size.
