Indeterminate Tomatoes are main season varieties that continue to grow and bear fruit all season long. Which is why they should be staked and pruned to a single stem. They will bear Tomatoes one cluster after another. Determinate or Bush Tomatoes will branch and bear Tomatoes on multiple clusters. After a short rest period they will continue to grow and will bear more fruit in later stages. Some staking is recommended to keep the early Tomatoes off the ground.
