When to discard a tomato plant?
 

Thanks again Ron. I´ve read a lot about growing, but I found nothing about the end of the life of a plant. When to discard a tomato plant? Does it fruit for more than a season? more than a year? Victoria.

Tomatoes are indeterminate plants which under the right conditions (like in a greenhouse) they will produce fruit continuously.
But here in Florida I get two complete harvests in the spring and fall under my shade cloth greenhouse.
