Do Tomato plants die after bearing fruit?
Yes, tomato plants have one life. They are not perennial. Are you sure you do not have a disease? I would talk to an old timer in your area, call the county extension agent and explain the problem or take a sample to the office, and sometimes the garden stores have experts that can help you. Often the problems are different for different areas of the country.
Reply:They should produce until the first frost--maybe 4 months. They are not supposed to die after producing once. As the weather warms up they need more water--that could cause the leaves to dry up. Also if you overwater that can cause the leaves to turn yellow and dry up. I would put some fertilizer on them and water well when needed and see if that helps. Your description doesn't sound like a disease or pest.
Reply:Yes, home grown tomato plants are expected to die after one crop. You have to replant them every year.
Reply:some do.and u have to replant them each year.but if you take realy good care of them they will last a long time.
