San Marzano tomato is a variety of plum tomato. Compared to the Roma tomato, San Marzano tomatoes are thinner and more pointed. The flesh is much thicker with fewer seeds, and the taste is stronger, sweeter, and less acidic
Water tomato plants moderately. Don't allow the soil to become either soggy or bone dry. Tomatoes are heavy feeders.
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.
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.
Prune the dead stuff out and gradually prune away the small multiple trunks to one strong, heathy one
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.
