Organic Non-GMO Open-Pollinated San Marzano Tomato Seeds

Many world class chefs consider this to be the world's finest paste tomato. This delicious, strong tasting red fruit has thick flesh and few seeds, making it perfect for sauces and salsa. Also great fresh or canned. Story has it that the San Marzano originated in Peru before making its way to the Kingdom of Naples in the 1700's. Here it is thought it was first planted in the area of San Marzano sul Sarno, where it was grown in the rich volcanic soil and shadow of Mount Vesuvius.

Growing Tips:

Indeterminate.  Do not plant seeds too early, may become leggy and/or root bound. If necessary, use a row cover to protect from cold nights. Use stakes for support. 

Seeds should be planted indoors and kept in a dome with a heated mat for 4-8 weeks. 

It is key that your new starts be hardened off.  This is a process that requires taking them outside during the day, for a period of time, before they are planted. This acclimates your seedlings to the outside world, meaning the elements like the wind and sun. We do it for several weeks to a month as this strengthens their stems and overall plant structure. 

  • Start for a short period of time initially, then graduate to more time each day
  • One week minimum is recommended
  • Bring them inside in the early evening and overnight
  • Keep an eye on them and constantly water them. Make sure they have not blown over.
