San Marzano horn tomato is a selection of the famous Campania variety, with elongated horn-shaped fruits, firm and low-moisture flesh, ideal for sauces and preserves.
It belongs to the species Solanum lycopersicum, family Solanaceae. An indeterminate-growth plant requiring staking, with elongated, cylindrical-to-pyramidal fruits typical of the San Marzano type.
Sow in a heated seedbed between February and March, with soil temperature between 20 and 25°C; transplant into the field after the last frosts, generally in May.
It prefers fertile, well-drained soil, sunny exposure and regular watering; the plant needs staking and periodic side-shoot removal to support fruit development.
Harvest is staggered from July to September, once fruits reach full red colouring while still keeping good flesh firmness.
It can be affected by downy mildew, alternaria and blossom-end rot in case of irregular watering; crop rotation and good ventilation help prevent the main plant diseases.
Its compact, low-seed flesh makes it perfect for peeled tomatoes, purées and thick sauces that hold together during cooking, in the tradition of Campania cuisine.
Rich in lycopene, vitamin C and potassium, San Marzano horn tomato has antioxidant properties and an excellent balance between sweetness and acidity.
