SAN MARZANO

SAN MARZANO

78 days. The granddaddy of the San Marzano family of sauce tomatoes. This one still ranks among the richest roma types we’ve trialed and is high in sugars, pectin, and flavor for the very best in sauces, pastes, and soups. The rosy red fruit are meaty and thick walled, reaching up to 5 inches long, and gather on the indeterminate plants in thick clusters.

Favorite Canning and Paste Tomato

These plants are prolific and very disease resistant. I grow them every year for canning. Other reviewers mentioned blossom rot. I have found this variety less susceptible to it that than most. Grown in southern MI.

4 plants = 1000+ tomatoes

Always wondered if it was worth the extra money for grafted plants. This year, growing 4 plants in zone 5b, proved that, yes, it is! I've canned 880 tomatoes this season! Received the plants in mid-May. The plants grew vigorously and became well-established. They weathered the summer drought and multiple 100+ degree days. They were only stopped by a hard freeze at the end of October. If I'd been able to ripen all of the tomatoes left on the plants, I would have reached 1000 easily.

A MUST HAVE in my garden

I decided to run a few tests in my garden this year. I tried starting tomatoes from seeds as well as planting grafted transplants, one of which was this San Marzano. This plant grew the largest, produced the most fruit, and overall - became the star of the garden. It's still going VERY strong and I suspect will for a few more months (I'm zone 8a). I had trouble with end rot with my OTHER tomato plants, (that I started from seeds) but not the grafted transplants. I did fertilize with calcium when I notice end rot on my other plants. I am now convinced, this is the way... at least for my growing conditions. I will be back for more next season!! Thank you!

Also would like to note, the photo is a good representation of the tomatoes cross section. Not a lot of juicy filling, so it makes for easier processing for sauces.

Best Tomato for Sauces and Tasty Fresh Too!

This is our first year trying the San Marzano and I'm sure glad that we did! What a great producer, no problems growing them (where in Oregon, Zone 8A). Nice big batch of 5+" tomatoes, with a second batch on now. Made them into a sauce, which was super easy to do and then we had spaghetti tonight with the leftover sauce it was that good! I definitely order more of these next year, probably double or triple the number, they were that good, that easy to grow and that well liked.

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.

Days to maturity are calculated from date of transplant.

Culture
• Determinate tomatoes: grow compactly, sprawling laterally, usually do not require staking, and fruit ripens over a short period of time
• Indeterminate tomatoes: grow on long vines, generally require pruning to 1 or 2 leaders that need to be trellised
• Fertile, well-drained raised beds covered with plastic mulch promote early growth and better yields
• Tomatoes are high feeders and will benefit from regular fertilization with Age Old Bloom
• To prevent blossom end rot use a high calcium amendment
• Overwatering can cause fruit to crack

Direct Sowing
• Not recommended

Transplanting
• Sow seeds in trays 6-8 weeks before anticipated transplant date; up-pot into 3-4 inch pots when the first set of true leaves appears
• Strong light and cooler temperatures (60-70°F) prevent plants from getting leggy
• Fertilize with Age Old Grow every 10-14 days
• When transplanting work in compost, 1/2 cup of TSC's Complete fertilizer, and handful of bone meal
• Determinates can be spaced 18-24 inches apart, indeterminates 24-36 inches apart
• Tomatoes can be buried up to the top 2 sets of leaves
• Use Kozy-Coats or Victorian Bell Cloches to protect young plants

Insects & Diseases
• Common insects: Flea beetles and tomato hornworms
• Insect control: Pyrethrin or row cover for flea beetles, and Monterey B.t. for tomato hornworms
• Common diseases: Early and late blight
• Disease prevention: A strict 3-4 year rotation, remove vines at the end of the year, fungicide

Harvest & Storage
• Harvest when fully ripe, do not refrigerate for best flavor
• Green fruit should be ripened in a cool, dark area; make sure fruit are not touching
