Tomatoes are typically grown as annual plants, meaning they complete their life cycle within one year. In most climates, they are not considered perennial plants. Tomato plants are sensitive to cold temperatures, and exposure to frost can damage or kill them.
However, in some tropical and subtropical regions with mild winters, tomato plants can behave like perennials, especially if they are protected from cold temperatures and continue to produce fruit for multiple years. In such areas, tomato plants may survive and continue to grow year-round.
In cold climates, it is common practice to replant tomatoes each year as annuals, starting from seeds or transplants in the spring and harvesting the fruit during the warm growing season. While tomatoes are not true perennials in these regions, they can sometimes self-seed, leading to the growth of new tomato plants in subsequent seasons if conditions are suitable.
