Start seeds indoors six weeks before last frost date.
Plant to the first set of true leaves to promote strong root growth.
Ensure that temperatures are mild and all chance of frost has passed before planting out, as Gildo Pietroboni is a tender plant.Gildo Pietroboni is named for the man who originally brought the seeds with him from Italy when he emigrated to North America.
The seeds were passed from Mr. Pietroboni to his son, whose friend shared them with Ferp Necciai of Monongahela, Pennsylvania. Ferp Necciai sent some seeds to David Lemasters of Pennsylvania in 2009, and David shared few of the original seeds with some tomato gardeners and SSE members in 2011. 1
