Tomato San Marzano

 Growing Tomato San Marzano

in Northeast Florida Vegetable Gardens

Tomato San Marzano is considered a plum tomato and is the classic Italian paste tomato perfect for sauce making. The intense flavor is complex and sweet.

The once hard to find Tomato San marzano was once localized to the Italian market and grown only in the rich volcanic soils near Mount Vesuvius. Although lore says that those rich volcanic soils and the Mediterranean climate give Tomato San Marzano their distinct flavor, they still seem to be making a name for themselves here in America, volcanic soils or not! Rapidly gaining popularity both in home gardens and on the shelves at grocery stores, San Marzano tomato has quickly become an American favorite.

The San Marzano tomato is a little thinner and longer than a traditional American plum tomato and has a pointed end rather than rounded. The thicker flesh, low acidity, and fewer seed count, along with the ease of removing them from their skins makes San Marzano an excellent sauce tomato selection. One of my personal favorite tomato plants that I think should be in every garden, every year!

Indeterminate tomato selection. Harvest 75-85 days.

Although San Marzano tomatoes are world renowned sauce tomatoes I still love to eat them fresh sliced on sandwiches and in salads. Or slice them in half long ways and throw them in your vegetable stir fry, and of coarse, San Marzano’s are perfect for preserving and fresh sauce making any way you serve them they are delicious!

Care of San Marzano Tomato in the Northeast Florida Vegetable Garden:

Staking your San Marzano Tomato plant:

San Marzano tomato is a fast growing indeterminate variety that is a heavy producer of inch wide by 2-5 inch long fruits. Traditional tomato cages will not be large enough to contain them unless heavy pruning is done. Consider making your own tomato cage from heavy duty cow fencing and make sure to strap it down with posts so your beautiful crop of San Marzano tomatoes don’t end up all over the ground after a North Florida rains storm.

Watering your San Marzano Tomato Plants: 

Newly planted tomato plants will require watering daily for the first few days to a week after being planted from seed or transplanted from an S & J Nursery container.

Once the tomato plants are established and growing, be sure to keep the soil moist by watering at least twice per week if rainfall is scarce. Container grown tomato plants will need watered 3 to 4 times per week, or every time the top two inches of soil is dry to the touch.

Mulching your San Marzano Tomato plants:

For maximum growth potential, mulching plants generously, this will help conserve moisture.

Fertilizing Your Tomato plants:

Feed every two to three weeks with an all purpose fertilizer like 6-6-6.

Or for an organic approach, try fertilizing with a mixture of fish emulsions and seaweed (kelp) at one ounce each per gallon of water. Apply semi weekly as a foliar spray.

If your vegetable plants look like they could use a boost, give them a good watering with homemade compost tea as soon as the top few inches of soil around your plant is dry to the touch!
