The Valley Annex | 247 S Alaska Street, Palmer, Alaska

Grow More Tomatoes in Alaska, Even with a Short Growing Season

Imagine walking into your garden this summer and finding healthy tomato plants loaded with fruit, knowing exactly how to care for them and what to do when Alaska’s unpredictable weather arrives.

Now imagine harvesting winter storage tomatoes that can continue providing food long after the growing season ends.

That’s what we’re working toward.

Join Seeds & Soil Farm for our 2027 Growing Tomatoes in Alaska Class, an in-person gardening workshop focused on growing productive tomato plants in northern climates.

We’ll explore the techniques that help tomatoes thrive despite Alaska’s cool nights, short summers, and unpredictable frost dates.

And the best part?

You’re taking the tomato plants home with you.

Every in-person registration includes three established winter tomato plants grown in one-gallon containers, 20 shallot sets, and 20 onion sets, along with a planting plan and practical growing instruction.

For 10 years, Seeds & Soil has been growing, testing, and saving seeds in Alaska. This class brings together our experience with tomato variety selection, season extension, plant care, and permaculture garden design.

How Do You Successfully Grow Tomatoes in Alaska?

Growing tomatoes in Alaska requires more than simply planting them outdoors after the snow melts.

Tomatoes are warm-season crops. Cool soil, chilly nights, and a short frost-free season can slow growth, delay flowering, and make fruit ripening more difficult.

We’ll explore how to work with these challenges rather than against them.

Choosing the Best Tomato Varieties for Alaska

Not all tomato varieties perform equally in northern climates.

We’ll discuss the differences between determinate and indeterminate tomatoes, how growth habits affect plant management, and why variety selection matters when the growing season is limited.

You’ll learn how to evaluate tomatoes based on their growing requirements, productivity, and intended use.

When to Transplant Tomatoes Outdoors in Alaska

Learn how soil temperature, nighttime temperatures, and frost risk affect transplanting decisions.

We’ll discuss how to harden off tomato plants, recognize suitable growing conditions, and protect young plants from cold weather.

Growing Tomatoes with or Without a Greenhouse

Do tomatoes need a greenhouse in Alaska?

Not always.

We’ll compare greenhouse growing, high tunnels, and protected outdoor locations, including how garden placement, wind protection, heat retention, and microclimates can improve growing conditions.

You’ll learn practical approaches to extending your growing season and protecting tomato plants when temperatures fluctuate.

Tomato Watering, Feeding, and Soil Health

Healthy tomato plants need consistent moisture, suitable fertility, and an environment that supports strong root development.

We’ll cover watering practices, nutrient management, soil conditions, and how to recognize common plant stress symptoms.

Pruning, Trellising, and Plant Management

Learn how tomato growth habits influence pruning and support requirements.

We’ll discuss appropriate spacing, airflow, trellising, and plant management techniques that help maintain healthy plants and make harvesting easier.

Pollination, Fruit Set, and Ripening

We’ll explore how tomatoes produce fruit, how temperature affects flowering and fruit set, and what gardeners can do to improve growing conditions during Alaska’s short summer.

You’ll also learn how to manage late-season fruit development and prepare for the first fall frosts.

What Are Winter Storage Tomatoes?

Winter tomatoes, sometimes called storage tomatoes, are varieties selected for characteristics that allow harvested fruit to remain usable longer than many conventional garden tomatoes.

Traditional tomatoes are often grown primarily for fresh eating during summer. Storage varieties offer another possibility: extending the usefulness of the harvest into fall and winter.

These varieties are especially interesting for Alaska gardeners because they provide another way to think about food production beyond the outdoor growing season.

During class, we’ll discuss:

• How winter storage tomatoes differ from typical garden tomatoes
• Variety selection and growing requirements
• How fruit maturity influences harvest decisions
• When and how to harvest storage tomatoes
• Handling and storage conditions
• How to recognize fruit that is no longer suitable for storage

Storage potential varies by variety, harvest maturity, handling, and storage conditions. Not every tomato will store for the same length of time.

Your registration includes three established winter tomato plants in one-gallon containers, giving you an opportunity to grow these fascinating varieties yourself.

Interplanting Tomatoes, Onions, and Shallots

Tomatoes don’t necessarily need to occupy a garden bed by themselves.

We’ll explore how tomatoes, onions, and shallots can be incorporated into a thoughtful interplanting design.

Your class includes 20 onion sets and 20 shallot sets, along with a garden planting plan demonstrating how these crops can share growing space.

We’ll discuss plant spacing, light requirements, root competition, airflow, soil coverage, and differences in harvest timing.

The goal isn’t to crowd as many plants as possible into a small space. It’s to understand how to arrange crops so they can grow productively together.

These concepts are part of a broader permaculture approach that emphasizes thoughtful design, plant diversity, and efficient use of available resources.

What Will You Learn in the Alaska Tomato Growing Class?

This class covers the tomato growing season from transplanting through harvest.

Topics include:

• Choosing tomato varieties for Alaska
• Determinate versus indeterminate tomatoes
• Hardening off and transplanting
• Soil and nighttime temperature requirements
• Greenhouse versus outdoor growing
• Microclimates and season extension
• Spacing, pruning, and trellising
• Watering, feeding, and soil fertility
• Pollination and fruit development
• Common tomato growing problems
• Ripening fruit in short growing seasons
• Harvesting and storing winter tomatoes
• Interplanting tomatoes, onions, and shallots
• Late-season plant protection and harvest planning

Our goal is for you to understand the entire tomato growing process, not simply how to put a tomato plant in the ground.

FREE Permaculture Design Course Recording

Complimentary access to our recorded course in celebration of Seeds & Soil’s 10th anniversary.

You’ll leave with the plants, the plan, and the knowledge to put everything into practice at home.

Celebrating 10 Years of Seeds & Soil

This year marks 10 years of Seeds & Soil, and we’re celebrating by giving our in-person students an additional opportunity to learn.

Every in-person class purchase includes FREE access to our Permaculture Design Course recording.

Permaculture encourages us to consider the entire growing environment, including sunlight, wind, water, soil, heat retention, structures, and natural microclimates.

These principles are particularly useful when growing heat-loving crops such as tomatoes in northern climates.

If you don’t have a greenhouse, I especially encourage you to watch this recording.

You’ll learn ways to identify and improve growing conditions using the features of your own property.

It’s our thank-you to the gardeners who have supported Seeds & Soil throughout the past decade.

Frequently Asked Questions About Growing Tomatoes in Alaska

Can you successfully grow tomatoes in Alaska?

Yes. Tomatoes can be grown successfully in Alaska when gardeners choose suitable varieties, provide adequate warmth and light, and use growing methods appropriate for their location. Greenhouses and high tunnels can improve reliability, but protected outdoor growing is also possible.

What are the best tomato varieties for Alaska?

The best varieties depend on whether you’re growing in a greenhouse, high tunnel, or outdoors, as well as your intended harvest. Early-maturing tomatoes are often useful in short growing seasons, while storage varieties offer different characteristics for gardeners interested in extending the usefulness of their harvest.

When can I transplant tomato plants outside in Alaska?

Tomatoes should be transplanted after frost risk has sufficiently passed and growing conditions are warm enough to support healthy growth. Tomatoes generally perform best when soil temperatures are at least around 60°F and nighttime temperatures remain consistently above approximately 50°F. Local conditions and protective structures can influence planting decisions.

Do I need a greenhouse to grow tomatoes in Alaska?

No, although greenhouses can make tomato growing more reliable in cool climates. Warm, sheltered outdoor locations, season extension, and carefully selected varieties can also support successful tomato production. We’ll discuss how to evaluate your growing conditions.

What are winter storage tomatoes?

Winter storage tomatoes are varieties selected for their ability to remain usable after harvest for longer periods than many ordinary fresh-eating tomatoes. Storage duration varies significantly depending on the variety, harvest maturity, fruit condition, and storage environment.

Can winter tomatoes really last for months after harvest?

Some storage tomato varieties can remain usable for several months under suitable conditions. However, storage life is not guaranteed, and fruit must be monitored for spoilage. We’ll discuss harvesting, handling, and storage practices during class.

Why are onions and shallots included with the tomato plants?

Onions and shallots are included to demonstrate interplanting and practical permaculture garden design. We’ll explore how crops with different growth habits and harvest timelines can share growing space while maintaining appropriate spacing, airflow, and access to nutrients.

Are the tomato plants already started?

Yes. Every in-person attendee receives three established winter tomato plants grown in individual one-gallon containers. This is a tomato-growing and plant-care class, not a tomato seed-starting workshop.

Is this class suitable for beginners?

Absolutely. We’ll cover the tomato-growing process from transplanting through harvest, including practical techniques for gardeners who have never successfully grown tomatoes before.

What happens if I cannot attend the in-person class?

If you cannot attend the live class, you’ll receive access to our self-paced online tomato-growing class. Seeds included with the online class, along with the onion and shallot sets, will be mailed to you.
