How to Care for the Plant

Water
Water tomato plants moderately. Don't allow the soil to become either soggy or bone dry. Tomatoes are heavy feeders.
Pruning
Prune the dead stuff out and gradually prune away the small multiple trunks to one strong, heathy one
Fertilizer
Use a fertilizer with an N-P-K ratio of about 5-10-10. Avoid high nitrogen fertilizers that can produce lush plants with little or no fruit. Use a water-soluble fertilizer for tomatoes grown in containers.

Soil
Ensure the soil is well-drained and never waterlogged. Before planting dig a generous amount of compost or well-rotted manure into the soil. Dig a deep hole for each San Marzano tomato, then scratch a handful of blood meal into the bottom of hole.
Temperature
It is important that the soil be sufficiently warm (60° F minimum) for planting Tomatoes.
Additional
When tomatoes were first brought to Europe from the Andes, they were thought to be poisonous. That's likely because of the plant's similarity to the deadly nightshade, or belladonna. For a while, the fruits served merely an ornamental purpose in the Old World.
