Andiamo is an F1 hybrid paste tomato that brings San Marzano authenticity to the home garden while delivering exceptional productivity and flavor. These elongated, bright red fruits grow to about 5 inches long and weigh 5 to 6 ounces each, with firm, meaty flesh that strikes a rare balance between sweetness and acidity. Ready to harvest in 60 to 69 days from transplant, this indeterminate vine thrives in full sun across hardiness zones 2 through 11, growing 3 to 8 feet tall depending on your growing season and support system.

Andiamo delivers the thick-walled, dense texture of a true San Marzano without sacrificing the fresh-eating experience. The flesh is firm enough to slice cleanly for a sandwich yet sweet enough to eat straight off the vine, making it genuinely dual-purpose. With strong resistance to Fusarium Wilt, Verticillium Wilt, Late Blight, Tobacco Mosaic Virus, Powdery Mildew, and Bacterial Canker, plus tolerance to Blossom End Rot, this hybrid handles the disease pressures that derail less resilient varieties. High productivity means you'll have abundant fruit for both fresh eating and preserving.
Andiamo excels at everything a cook asks of a tomato. Slice it fresh for summer salads and sandwiches, where its balanced sweetness and acidity shine. The firm, meaty flesh and low seed count make it exceptional for making salsa, tomato paste, and sauce. Many gardeners grow Andiamo specifically to preserve large batches, since the fruit's dense structure holds its integrity through cooking and reduces to a concentrated, flavorful product.
No timeline data available yet for this variety.
Start seeds indoors 6 to 8 weeks before your last spring frost date. Sow seeds at a depth of 1/4 inch in warm soil (70 to 80 degrees Fahrenheit) and maintain consistent moisture. Seedlings will emerge in 5 to 10 days and need bright light, either under grow lights or in a sunny window.
Transplant seedlings outdoors once nighttime temperatures reliably stay above 50 degrees Fahrenheit and the soil has warmed to at least 60 degrees. Harden off plants by gradually exposing them to outdoor conditions over 7 to 10 days. Space them 24 inches apart in rows 36 inches apart.
Pick Andiamo tomatoes when they are fully colored deep red but still slightly soft to gentle pressure. Harvest when fruits reach their full 5 to 6 ounce size with the characteristic elongated shape. For fresh eating, pick fully ripe fruit. For sauce or paste, you can harvest slightly earlier when the fruit is firm but not yet at peak softness, allowing you to preserve larger batches. Harvest regularly to encourage continued flowering and fruit set.
Because Andiamo is indeterminate, it will grow continuously throughout the season and benefit from light pruning. Remove suckers (shoots that grow between the main stem and branches) to direct energy toward fruit production and improve air circulation. Prune lower foliage once the plant is established to prevent soil-borne diseases from splashing onto leaves during watering.
