These are notorious for dropping tomatoes, and thus, seeds everywhere. This can happen for a very long time. It is hard to say when they will stop.

As long as you keep the soil in proper condition, you can see volunteers come back every year for years to come.

The only drawback is that disease organisms may build up when same crops are grown in same spot year after year.
