85 Days to maturity (from transplant). Solanum lycoperscium. San Marzano (Indeterminate) Tomato Seeds. Non-GMO, annual, open-pollinated, heirloom, indeterminate, paste tomato. Often compared to the famous Roma tomato in terms of shape, size, and flavor, San Marzano seeds grow a traditional Italian cultivar commercially produced throughout the 20th century. Introduced in 1926, the San Marzano seed has become an Italian staple where it is known locally in Valle del Sarno as Pomodoro San Marzano dell'Agro Sarnese-Nocerino. ~7,500 seeds/oz.
How to Grow San Marzano Tall Vine Tomatoes from Seed
Tomato seeds are a warm weather crop best if started indoors about 6-8 weeks prior to final spring frost. Plant 2-3 seeds 1/4" deep per cell in fertile, humusy, and well-drained soil with a pH of 6.0-6.8. San Marzano seeds germinate in 5-14 days. Transplant best starts to 1 per pot or 18-36" apart in the garden. Ideal for container gardening. Before sowing, know whether the seed is determinate or indeterminate, as each will exhibit different habits.
Determinate varieties mature to a predetermined size, producing its fruit all at once with only a minor need for staking. Indeterminate varieties grow indefinitely through the season, producing non-stop fruit while requiring heavy support. San Marzano Tall Vine tomato seeds are an indeterminate tomato crop.
Non-GMO San Marzano Short Tall Tomatoes in the Vegetable Garden
Tomato is the quintessential staple of summer gardening and arguably offers the most seed diversity among all seasonal fruits. Available in every possible color, shape, and size, tomato is a high-heat and full sun favorite that thrives from container and patio gardening. Along with cucumber and summer squash, the tomato plant is one of the most productive, hardy, and heavy fruiting crops of the season.
San Marzano seed matures indeterminately, boasting unique 4 oz 5 inch-long Roma tomatoes traditionally used in the Mediterranean for canning.
Harvesting San Marzano Tall Vine Tomatoes
Smaller varieties, such as the cherry, are ready to harvest at about 80 days from sowing, while larger varieties like the beefsteak may require a few extra weeks. Although vine-ripened fruit is always preferred, tomatoes can just as easily be harvested early and ripen indoors by being stored in a paper bag or box along with a banana for its ethylene gas. Ripest tomatoes may be pulled from the vine by hand, while more firm ones should be clipped with shears.
About San Marzano Tall Vine Tomato Seeds
Solanum lycoperscium. (80 Days). Indeterminate tomato vines (Tall vines that need staking)
San Marzano is from Italy originally, but does extremely well here in California also.
Nice tall vines produce heavy yields of bright red, 2-3 inch, 5-6 oz, plum-type fruit over a long season.
San Marzano is the premier canning tomato with heavy walls, very few seeds, and little juice.
This is still the canning industry's choice in Italy.
A traditional Italian heirloom tomato, the San Marzano is known for its high sugar and pectin content, ideal for robust, yet delicate purees, sauces, and soups.

Pests and Diseases:
Common pests known to harm tomato plants, in general, include the tomato hornworm, cutworm, aphids, flea beetles, tomato fruit worms, and whiteflies. Also, watch for common diseases such as blossom end rot, fusarium wilt, powdery mildew, verticillium wilt, late blight, bacterial canker/spot, and tobacco mosaic virus. Most of these can be prevented by maintaining a regular watering schedule and avoiding overwatering. Regularly check your plants for pest damage throughout the season. For treating pest and disease problems, we recommend using an organic neem-based product.
