Summary

Choosing the right tomato variety for your climate and growing conditions is crucial for a successful and flavorful harvest, with considerations including fruit size, plant type (bush or vine), and the specific needs of mild or hot climates.

Abstract

Selecting the appropriate tomato variety is the first and most important step in growing delicious tomatoes. The success of the fruit's flavor and size is heavily dependent on the amount of heat available for ripening, with larger tomatoes requiring more warmth. Gardeners must decide between determinate (bush) and indeterminate (vine) types, with the latter requiring sturdy support. For cooler climates, smaller varieties such as 'Early Girl' and 'Oregon Spring' are recommended, while hotter regions can accommodate larger beefsteak tomatoes. Heirloom varieties are cherished for their flavor but are more susceptible to disease, though grafted options can mitigate this risk. Additionally, positioning tomato plants against a south-facing wall can enhance growth by retaining and radiating heat.

Opinions

  • Larger tomatoes may not develop optimal flavor in cooler regions, making smaller varieties a better choice.
  • Indeterminate tomato varieties are typically more productive over a longer period compared to determinate ones.
  • Grafted tomatoes offer the flavor of heirlooms with increased vigor and disease resistance, though they come at a higher cost.
  • Planting tomatoes against a south-facing wall is recommended for maximizing heat retention and plant growth.
  • Early season planning and seed selection are key to a successful tomato harvest, with seed companies offering a more diverse selection than local nurseries later in the year.
  • The author emphasizes the importance of not being swayed by attractive catalog photos and instead focusing on the details when selecting tomato seeds.

What’s the Best Tomato to Grow?

The answer depends on your location and gardening conditions

If you want to grow truly delicious tomatoes this summer, the first step is the most crucial to your success: picking the best variety for your climate and growing conditions. Make the wrong choice and you’ll get fruit that is smaller and blander than you were hoping for. Make the right choice and you can have a bounty of fruits that are ripe, juicy, and full of flavor.

And the time to choose is now, when seed companies are well stocked with a selection of tomato varieties that is more diverse and plentiful than what you’re likely to see in seedling form in your local nurseries later in the year. Shopping for seeds now will improve your chances for tomato success, but only if you pay attention to the details and don’t allow yourself to get seduced by the glossy catalog photos of tomato porn.

Here’s what to pay attention to when you shop for tomato seeds.

More heat = Bigger fruit

When selecting tomato varieties, keep in mind that the bigger the fruit, the more heat you need for ripening. Without a lot of heat, larger tomatoes may grow but not develop great flavor. That means cooler regions will have a harder time growing beefsteak tomatoes but may do fine with the smaller fruits, which can still pack a lot of flavor into a small package. That includes everything from the tiny currant and grape varieties to cherry, campari (tomatoes-on-the-vine), slicing, or maybe even paste/plum varieties.

Bush vs. vine

In addition to climate concerns, you should also pay attention to whether the plants are determinate or indeterminate.

  • Determinate varieties are bushier, more limited in height, and can sometimes get by without staking or other support. They tend to bear the heaviest crop in a shorter time frame, which can be helpful if you want to plan on canning in big batches. Also, if you want to grow tomatoes in containers rather than in the ground, determinate varieties are your best option.
  • Indeterminate varieties are more like vines and can grow to 6 or 7 feet with the proper support. Be prepared to provide some heavy-duty caging or a trellis for these plants; once they start fruiting, branches can get quite heavy and those small wire tomato cages you see in the garden centers are probably not going to be sturdy enough. Indeterminate plants are typically more productive than determinate types, bearing fruit over a longer period of time.

Tomatoes for mild climates

For areas with cool or short growing seasons, recommended varieties include ‘Early Girl’, ‘Fourth of July’, ‘Stupice’, ‘Gold Nugget’, and ‘Oregon Spring’. Smaller tomatoes (cherry, grape, or currant) tend to do well in cooler areas as well. Some of the favorites of the small tomatoes include ‘Sun Gold’, ‘Candyland’, ‘Sweet 100’, ‘Tumbler’, and ‘Juliet’. Look for seeds that mature in 75 days or fewer.

Tomatoes for hot climates

In hot-summer areas, you can take on growing the biggest of the varieties. Large beefsteak tomatoes do well in these regions; recommended hybrids include ‘Beefsteak’, ‘Big Beef ’, ‘Damsel’, and ‘Delicious’. Other heat-loving tomatoes to try include ‘Green Zebra’, ‘Pink Berkeley Tie Dye’, and ‘Solar Flare’. Those hot summers mean that you can broaden your choices to include varieties that require up to 85 days to mature.

Specialty varieties

Heirloom varieties gain more fans every year, but they do have some challenges in terms of their susceptibility to disease. For tomato lovers, the flavor of heirlooms may be worth the risk. Some favorite heirloom varieties include ‘Brandywine’, ‘Mortgage Lifter’, ‘Green Zebra’, ‘Black Krim’, ‘Cherokee Purple’, ‘Marvel Stripe’, and ‘Principe Borghese’.

Be on the lookout for grafted tomatoes, which are appearing on the market more frequently. By grafting heirloom varieties onto hybrid rootstocks that are more vigorous and disease resistant, growers have created plants that offer the flavor and variety of heirlooms without so many of the problems. Only a few growers are doing this so far, and the plants are more expensive than typical tomato plants, but they tend to be high-yielding and some people even report getting a second year of tomatoes from the plants.

Bonus tip

Want to find the ideal spot in your garden to grow tomatoes? Plant them against a south-facing wall or fence, which retains the heat from the afternoon sun and radiates it back onto the plants. Your tomatoes will love it!
