Beat the Fall Frost: Early Ripening Tomatoes for Northern Gardeners

Short-Season Tomatoes

If you garden somewhere with late spring frosts, early fall frosts, or cool summers, you know the struggle: never enough ripe tomatoes before the first fall frost threatens to end tomato season.

The solution? Early-ripening tomato varieties suited to short growing seasons and coolish summers.

Instead of waiting 85–95 days for large beefsteak tomatoes that rarely ripen in time, northern gardeners can harvest ripe tomatoes in as little as 50–65 days — sometimes even earlier with protection.

Here’s the gist of this article:

  • What “early ripening” and days to maturity means

  • Top tomato varieties for cold climates (including tomato varieties with a Canadian pedigree)

  • Tips to boost your harvest in a short season

I grow lots of beefsteak and other “late” tomato varieties. But I always grow a few early tomato varieties so that I have ripe tomatoes earlier.

In my own Toronto garden (Canadian Plant Hardiness Zone 6a) I have a long enough season and the summer heat needed to ripen large, juicy beefsteak tomatoes. But I grow early ripening tomatoes too, as a way to get the earliest possible tomato harvest. One other benefit of early maturing tomatoes is that in years when Late Blight rears its head I’ve already enjoyed lots or ripe tomatoes!

What Makes a Tomato “Early Ripening”?

There are a few things to think about when it comes to tomatoes for a short growing season.  

  • Days to maturity

  • Timing: Early to late

  • Fruit size

  • Cool-temperature tolerance

Understanding Days to Maturity

Days to maturity (DTM) is a relative measure that gives you a clue to how long a tomato will take to ripen. Don’t think of DTM as an exact number of days before you have a ripe tomato in your hand: It’s always approximate, because many things (your climate, the weather, growing conditions) affect ripening speed. But DTM is a great tool when comparing one tomato variety with another.

(By the way, for crops that we plant directly in the garden, DTM refers to the number of days from seeding until harvest; while for crops we transplant into the garden (e.g. tomatoes), DTM refers to the number of days from transplanting into the garden until you harvest your first ripe tomato.)

Timing: Early Maturing Tomato Varieties

As you investigate early maturing tomato varieties, you might notice that some sources give a days-to-maturity rating, while other sources simply categorize tomatoes as ultra early, early, mid-season, and late. So you might wonder how to compare varieties if ripening speed is explained differently.

Use this guide:

  • Ultra-early: 45–55 days

  • Early: 55–65 days

  • Mid-season: 70–80 days

  • Late: 80+ days

Fruit Size and Plant Type

Smaller-fruited tomato varieties often ripen more quickly than large beefsteak types.

Smaller-fruited varieties and determinate varieties (bushier plants that set fruit in a short window of time) very often ripen more quickly. When I teach gardening classes, gardeners in cool coastal climates often tell me they focus on cherry tomatoes and small-fruited tomato varieties.

Cold Temperature Tolerance

When you see a tomato variety described as cold tolerant, it doesn’t mean it will thrive in cold conditions—because tomatoes are a heat-loving crop. It just means that the cold-tolerant tomato varieties can set fruit at temperatures slightly lower than other tomato varieties. It’s not a huge temperature difference, often just a few degrees, but it can be enough to give you tomatoes sooner. And that matters where the growing season is short.

5 Great Early Ripening Tomato Varieties for Cold Climates

These early ripening tomato varieties are proven performers for short growing seasons. They’re also widely available, so they’re a good starting point if you’re new to growing early maturing tomatoes.

1. Glacier

Gives small, red slicing tomatoes. Early and cool-tolerant. 55 days.

2. Stupice

Early, great flavour, and cool-tolerant. Small, red slicing tomatoes. 55–60 days. Great taste. This is my favourite early ripening tomato.

3. Sub Arctic Plenty

I’ve grown this super early tomato variety for years. Reliably the first tomato in my garden. 45–50 days. Can’t argue with that!

4. Evan’s Extra Early

Good flavour. This mid-sized tomato is from Dr. Ieuan Evans of Alberta, a cold-climate gardener who also released the Evan’s Cherry. 57 days.

5. Early Girl

This is a hybrid tomato that’s been around since the 1970s and is widely available. It’s still around because it’s early, has a good taste, and keeps well. ~57 days.

Early Ripening Tomato Varieties with a Canadian Pedigree

Because of the short growing season in many parts of the country, and the cool, coastal summers in other areas, there are many early maturing tomato varieties from Canada. Sometimes the variety name gives it away—though not always. If this interests you, here’s a list of Canadian early ripening tomato varieties.

Final Thoughts: Short Season Tomatoes

Choosing an early maturing tomato variety is a simple way to harvest more tomatoes in areas with a short growing season or cool summers. It’s also a way gardeners in warmer areas can enjoy an earlier tomato harvest.

FAQ: Short Season Tomatoes

What is the earliest ripening tomato variety?

One of the earliest is Sub Arctic Plenty, clocking in at under 50 days.

Can tomatoes grow in Zone 3?

Yes. Choose early varieties and use season extension techniques in the spring and fall.
