How long do tomato plants fruit for before you need to plant new ones?

The length of time that tomato plants fruit for can vary depending on the variety of tomato, as well as growing conditions. Determinate tomato varieties typically produce fruit for a set period of time, usually around 6-8 weeks, before the plant stops producing fruit. Indeterminate tomato varieties, on the other hand, can continue to produce fruit for several months or even an entire growing season. These types of tomatoes must be pruned regularly for better air circulation and reduced risk of diseases and pests.

In general, tomato plants will need to be replanted after one growing season. This is because tomato plants are considered annual plants, meaning their life cycle is complete in one year. After the plant has produced fruit and the growing season has ended, it will begin to decline and eventually die.

For ongoing tomato plant production, you can plant successive crops throughout the growing season to have continuous availability. Plan them every 3-4 weeks for a steady harvest.
