San Marzano Italian Tomato Seeds. A determinate strain of the almost legendary paste tomato. The 2 to 3 ounce, oblong, red fruits can be processed into a rich, thick paste or sauce with unforgettable flavor. San Marzano Tomato seeds are also an excellent tomato for sun drying. Holds well on vine or in storage. These are heavy producers. 70 to 90 days.

Compared to the Roma tomato, San Marzano tomatoes are thinner and more pointed. The flesh is much thicker with fewer seeds, and the taste is stronger, sweeter and less acidic.

Start From Seeds: Though you can purchase young San Marzano plants from garden centers, growing your own from seed has much more to offer! Not only do you get to know the age of your tomato plant, you'll know exactly how and where it was grown. Timing and proper seedling care is important when it comes to maximizing yields. Plant seeds indoors six to eight weeks before the date of the average last spring frost.

Large Container: If you plan to grow them in containers, choose the largest one that you can find. Growing with great vigor, these tomato plants have a root system to match. Small containers will only cause the roots to cramp and tomato production to decrease. To reach the maximum tomato production potential, grow these plants in 20-gallon containers.

Tomato Cage: Although these plants will not grow as large as other indeterminate varieties, they will still need the support of a tomato cage. Select a cage that is at least 5 feet tall for the best results.
Full Sun: Like all other tomato plants, the San Marzano variety will need at least 6–8 hours of daily direct sunlight. While they will grow in slightly less, the yields and fruits themselves will be smaller.

Fertile, Well-Draining Soil: These plants are heavy feeders and will require the in-ground gardener to amend existing soil with plenty of compost or aged manure. Container gardeners should select the highest quality potting soil available. In either case, ensure that the soil drains properly. Slow-draining soils can smother tomato roots and cause rot.

All multiple orders of the same seed are put in the same bag. For example if you order 500 beefsteak tomato seeds x 3 then 1500 seeds will be put in the same bag. We do not send out 3 individual bags with 500 in each. This goes for all seeds unless they are listings of different seeds.
