Seed selection
To encourage genetic improvement, we select from millions of seeds only those deriving from the fruits of strong and vigorous plants. The seeds are obtained from San Marzano plants that have distinguished themselves during the various vegetative phases and have produced berries with a high quality standard. The nursery takes care of sowing in polystyrene containers which, floating on the water, accompany the fragile plant for about 1 month.
