History of Roma Tomatoes

Tomatoes originated in South America and were first cultivated in Mexico. Tomato plants were then introduced in Europe in the 1600s by Spanish explorers.

Fresh-picked local tomatoes were embraced by the Spanish and Italians, but Northern Europeans were suspicious of them. They believed that the tomato was poisonous and only used them as decorations.

With the help of enthusiastic gardeners such as Thomas Jefferson, tomatoes began to be widely consumed in the USA by the mid-1800s.

They are now considered staple foods across the world.

Roma tomatoes are an open-pollinated variety of tomatoes and the United States Department of Agriculture (USDA) developed them in Maryland in 1955.

They descended from the Italian San Marzano Tomato, and have a few unique characteristics.

Characteristics of Roma Tomatoes

Roma tomatoes are hybrid tomatoes.

The determinate Roma plants reach a height of around 3 feet when mature. They are resistant to verticillium wilt and fusarium wilt – reflected in their full name, Roma VF.

Ripening Season

Roma tomatoes are summer fruits and require planning to ensure that there is a continuous crop of ripe fruits throughout summer.

Typically, Romas are ready to harvest around 100 to 120 days after their seeds are planted. Since they’re mid-season tomatoes, transplanted seedlings mature into ripe tomatoes after around 75 days.

Tomato Qualities

This plum tomato type is elongated with an egg or pear shape, has a bright red, thick peel, and a lot of solids. Roma tomatoes also have fewer seeds and aren’t as juicy as regular tomatoes.

Roma tomatoes have a generally balanced taste, but their raw tomato flavor can also be considered naturally sweet or tart.

Tomato Size

Romas are larger than cherry tomatoes and grape tomatoes. The Roma fruit size is around 3 inches long and can weigh about 2 ounces.

Planting Zones

Roma tomatoes can grow within the USDA’s (United States Department of Agriculture) plant hardiness zones 3 to 11. Keep in mind that these summer-loving fruits thrive best between 55 degrees Fahrenheit (13 degrees Celsius) and 90 degrees Fahrenheit (32 degrees Celsius).

Size and Spacing

The Romas can grow between 4 to 6 feet tall so to ensure the best quality tomatoes, plant them 24-36 inches apart in a row. Plant your rows 36-48 inches apart.

Roma tomatoes need the basic care the average tomato variety requires.


Tomatoes need a minimum of 6 hours of direct sunlight every day. This is to ensure maximum growth as these are warm tomatoes.


Their soil requirements include proper drainage, and soil that is warm and rich in organic content. Slightly acidic soil is tolerable, although Romas do best with pH levels ranging between 6 to 6.5


Roma tomatoes, once planted, need to be watered at least once a week since they need plenty of water. A Roma planted in your garden requires about 1 to 1.5 inches of water per week.

However, if you are growing Romas in a pot or container, you’ll need to water them twice a day.

Roma tomatoes are bush varieties and do not require pruning. You can still trim the plant to get rid of any unwanted and damaged areas, but don’t overdo it as this could affect the yield.

When To Harvest Roma Tomatoes

A Roma’s exterior is firmer to the touch than other tomatoes, even when unripe. The best way to know when your Romas are ready for picking is when the vegetable achieves an even shade of deep red, pink, or orange all over.

Romas don’t tolerate frost well. If the temperature outside falls to 70 degrees Fahrenheit (21 degrees Celsius) and below, you’ll want to pick them right away. If they’re still a bit green, continue ripening them inside paper bags and store them in temperatures around 60 degrees Fahrenheit (16 degrees Celsius).

These are the perfect tomatoes for canned tomato products since they tend to ripen in large batches.

Shelf Life

You’ll be glad to know that Romas have one of the longest shelf lives among tomatoes (second only to the Sofol variety) and last up to 15 days after picking. Keep in mind that the 15 days only applies to Romas that are refrigerated. If you don’t refrigerate your tomatoes, consume them within a week.

Your Romas have started to go bad when you notice the following:

  • The flesh becomes tender in areas and may leak juices from the inside.
  • Mold begins developing on the surface.
  • Fruit flies begin circling them.
