Sauce/Paste Tomatoes

San Marzano Gigante 3 Tomato

San Marzano Gigante 3 Tomato


90 days. A heftier version of any San Marzano tomato that we have trialed with a magnificent, robust flavor to boot. Large, open, indeterminate plants produce enormous, meaty fruit measuring 2 1/2 inches wide and 7 inches long. Ruby red tomatoes have green streaked shoulders and very few seeds. These giants will go a long way in sauce and salsa recipes.
Also available as a plant.

Lycopersicon lycopersicum: The first ripe, juicy tomato of summer is a delicious milestone of the season for gardeners. Each year we test and evaluate more than 250 tomato varieties to bring you the most flavorful, best performing selections, for every desired use. An array of nutrients and antioxidants including the especially potent lycopene, found in its highest concentration in tomatoes, supports healthy eyesight, cardiovascular health, cancer-fighting capacity, and more.
Sauce varieties are very low in juice and high in pulp. These cultivars require much less cooking time to obtain a thick sauce because they contain far less water than tomatoes bred for fresh eating. These same qualities make them excellent for drying. What's more, cooking into sauce or paste triples the available lycopene and beta-carotene compared with raw tomatoes! While our sauce varieties are early-maturing and productive, yields will vary according to the climate in your area.

CULTURE: Sow seeds indoors into sterile seedling mix 6-8 weeks before your last spring frost. Plant, water lightly, and cover with plastic or a Propagation Dome to keep the seeds from drying out. When the first set of true leaves has emerged, up-pot into 3-4 inch pots and place in an area with full light and cooler temperatures (60-70°F). This will help prevent legginess. Water carefully, allowing the soil to dry on the surface between watering, but don't let the plants wilt. Fertilize with fish emulsion every 10-14 days. Seven to ten days before you want to transplant outside, set the plants in a sheltered area outdoors to harden off. Bring in or cover at night to protect from frost. After the danger of frost has passed, transplant into well worked garden soil. Blend 1/4 cup of our complete fertilizer into the soil around each plant. If you have acid soils or have been bothered by blossom end rot, a handful of bone meal should also be added. Space determinate varieties 18-24 inches apart and indeterminate varieties 20-30 inches apart. Allow 3-4 feet between rows. If your plants have become leggy, plant them deeper; the stems will actually sprout roots. Water very lightly at first, allowing the stems to adapt. To promote early growth and better yields use season extending products such as Wallo' Waters, Kozy Coats, Victorian Bell Cloches, or Red Plastic Mulch.
DETERMINATE/INDETERMINATE: Determinate varieties spread laterally and therefore do not require staking. Determinate varieties ripen at once so are a good choice for gardeners who love to can. Indeterminate varieties grow vertically until the bitter end and need to be staked or trellised for best production. They produce fruit until frost, leaving you some green tomatoes at the end of the season.
INSECTS/PESTS: Use Pyrethrin or crop row covers to discourage flea beetles early in the season, when they can be most destructive. Tomato hornworms can be controlled with Bacillus thuringienses (a bacteria also known as B.t.) sold as Monterey B.t. (ZIN503).
DISEASES: Natural genetic plant resistance is the best form of disease control. For diseases like early and late blight, a strict 3 year rotation and a sanitation program that includes destroying all the vines at the end of the year are your best defenses. Contact your local county extension agent for more information.
SEED SPECS: Minimum germination standard: 80%. Usual seed life: 3 years. Days to maturity are calculated from date of transplanting; add 30-35 days if direct seeding.

Fabulous Tomatoes

I had some seeds of San Marzano Gigante 3 from last year so I grew plants. I can not compare the magnificence of these tomatoes. Right now Sept 5/2015 I harvested 20 huge tomatoes from 2 plants, each one about 3/4 Lb or heavier. When completely red ripe the skin comes off easily, they have a dew seeds and the taste is heavenly, great for salad or sauces or anything needing a great tomato. Every seeds from Territorial has been great for me, thank you Territorial.

It is the first year that I tried this variety, and I have 6 big robust plants right now that I have been harvesting. I grew them in cages and only pruned them once after transplanting when they really started to take off. The plants are robust and seem to be very productive. Some of the fruits have blossom scars which looks like blossom end rot but does not affect the quality, which is very good. Fruits resemble pasilla peppers more than roma tomatoes, but they are huge, one weighed 15 oz. and the flavor is very good. Juicy, few seeds, flavor is sweet and not acidic, but delicious. I didn't grow them for fresh eating though, but to process into sauce. For sauce, they are much juicier and sweeter than traditional sauce tomatoes, almost too sweet when cooked down. For that reason, I give them 4 stars because they are not really a sauce tomato as advertized.
