How to Choose the Right Tomato for Your Garden

If you grow vegetables in the summer, you probably grow tomatoes, and they’re often the first vegetable a budding gardener tries to grow. It’s not a bad call—there’s nothing like eating a vine-ripened tomato you grew yourself.

But not all tomatoes are created equally, and it can be confusing to decide which tomatoes to grow. There are countless varieties, and instead of choosing based on the color or a cute name, learning the characteristics of different tomato types can help ensure a more successful tomato growing (and tomato eating) season. Whether you are growing tomatoes from seeds or buying seedlings at the nursery, here’s what to consider to help you choose the right tomato for you. 

Determinate versus indeterminate tomatoes

Before you get into flavor, color, or anything else, you should know about the two types of tomatoes. All tomatoes are either determinate or indeterminate, and at the most basic level, the difference is about harvesting: Determinate tomatoes produce all their fruit in a few weeks’ time, while indeterminate tomatoes produce over the course of a season. This seems like a simple choice, because who wouldn’t want a season full of tomatoes? And if you’re harvesting, say, slicing tomatoes for sandwiches, a season full of tomatoes would make sense. But if you’re harvesting paste tomatoes to make sauce, you more likely to want them all at once, so you can make a few big batches of sauce. 

These two kinds of tomatoes grow differently, too: Determinate tomatoes tend to be bushier, and grow to a set point and then stop. Indeterminate tomatoes grow taller like a vine, and never stop growing and setting flowers. You can prune indeterminate tomatoes to shape the plant, but should never prune determinate tomatoes, or you’ll limit the fruit you’re capable of growing.  

Every plant tag or catalog listing will tell you if a tomato is determinate or indeterminate, but ife in doubt, do some research. You can search for the name of a tomato online to find out, or ask someone at the nursery. 

Tomato type determines shape, size, and juiciness

It takes nothing more than a trip to the grocery store to see the varieties of tomatoes on offer. There are cherry tomatoes (which aren’t just little baby tomatoes), paste or plum tomatoes, and globe tomatoes. Occasionally you’ll even see slicers. Each of these tomato types serves a specific purpose.

Slicers are best for sandwiches

When you picture the ideal tomato, you’re likely imagining a slicing tomato. Palm sized or bigger, slicers can top a pound in weight, and come in a few different shapes. There are heirloom type tomatoes like Purple Cherokee or Berkeley Tie Dye, which have big, defined lobes and shoulders. There are globe tomatoes, which are what you usually buy in the supermarket—tennis ball sized, and very round and smooth. There are heart shaped tomatoes, like Cuoer di Bue and Oxheart, that have a distinct point at one end and tall shoulders, which makes them resemble hearts.

The thing that truly defines a slicer, though, is that they have a good amount of juiciness—more so than other tomatoes—but also enough meat for slices of tomato to hold together. This makes them ideal for sandwiches or a beautiful caprese salad. 

Paste or plum tomatoes make great sauce

While you could make tomato sauce from any tomato, the best tomato sauce tomato is a paste or plum. These elongated tomatoes tend to have more meat and less juiciness, making them ideal for cooking and canning. The shape makes them easy to peel and ideal for roasting. Classic paste tomatoes include Roma (a determinate) and San Marzano (an indeterminate), both of which have spectacular flavor. You can also consider varieties like Amish Paste, an indeterminate popular for its size and production, if not so much its taste. Growing multiple varieties (say, one great-tasting tomato and one well-producing tomato) and using both will yield more sauce, while maintaining the flavor.
