Thriving in the North: Best Crops to Grow in Alaska

Alaska, the largest state in the U.S., is known for its vast, untamed wilderness and diverse ecosystems. Despite its northerly location and long, cold winters, Alaska's climate offers opportunities for growing a variety of crops. With careful planning and the right techniques, gardeners and farmers can cultivate a surprising range of plants in the Last Frontier. Let's explore the crops that thrive in Alaska's unique climate.

Alaska's climate is characterized by long, cold winters and short, cool summers. The growing season typically ranges from 90 to 150 days, depending on the region. While this may seem limiting, Alaska's diverse climate zones, from the mild Southeast to the Arctic tundra, allow for a variety of crops to be grown. In this article, we'll delve into the crops that can be cultivated in Alaska, focusing on vegetables, fruits, and grains that have proven successful in the state's unique conditions.

Vegetables

Vegetables are the backbone of Alaska's gardening scene. The state's cool climate and long daylight hours in the summer create ideal conditions for growing a variety of frost-tolerant and cold-hardy vegetables. Here are some vegetables that thrive in Alaska:

Alaska's climate is well-suited for growing brassicas, a family of vegetables that includes cabbages, broccoli, kale, and Brussels sprouts. These crops are known for their ability to tolerate cold temperatures and can be grown throughout the state. In fact, some varieties, like 'Savoy Perfection' cabbage and 'Blue Wind' kale, have been specifically bred for Alaska's climate and have shown exceptional performance in the state.

Brassicas

Brassicas are easy to grow and can be started from seed directly in the garden or indoors for an earlier harvest. They prefer well-drained soil and full sun but can tolerate partial shade. Some brassicas, like kale and collard greens, can even survive under a blanket of snow, making them excellent choices for overwintering crops.

To grow brassicas in Alaska, start seeds indoors 4-6 weeks before the last spring frost date. Transplant seedlings into the garden after the danger of frost has passed. Space plants 12-24 inches apart, depending on the variety. Keep the soil consistently moist, and apply a balanced fertilizer every 4-6 weeks. Brassicas are ready to harvest when the heads are firm and the leaves are fully developed.

Root Vegetables

Root vegetables, such as carrots, beets, and potatoes, are also well-suited to Alaska's climate. These crops prefer cool temperatures and can be grown throughout the state. In fact, Alaska is known for its high-quality potatoes, with some varieties, like 'Yukon Gold' and 'Kennebec', performing exceptionally well in the state's cool soils.

To grow root vegetables in Alaska, start seeds indoors 4-6 weeks before the last spring frost date or direct sow outdoors after the soil has warmed to at least 40°F (4°C). Space plants according to the specific requirements of each vegetable. Keep the soil consistently moist, and apply a balanced fertilizer every 4-6 weeks. Harvest root vegetables when they reach the desired size, usually 2-3 months after planting.

Fruits

Alaska's climate may seem too harsh for fruit production, but with careful selection of cold-hardy varieties and proper management, gardeners can grow a variety of fruits in the state. Here are some fruits that have shown success in Alaska:

Apples, plums, and cherries are among the fruit trees that can be grown in Alaska, particularly in the milder regions of the Southeast and Southcentral areas. These trees require a certain number of chill hours to produce fruit and should be selected based on their cold hardiness and ability to tolerate Alaska's short growing season.

Apples

Apples are one of the most popular fruits grown in Alaska. Varieties like 'Honeycrisp', 'Liberty', and 'Haralson' have shown excellent performance in the state. These apples are known for their cold hardiness, disease resistance, and exceptional flavor.

To grow apples in Alaska, select a location with well-drained soil and full sun. Plant trees in early spring or fall, spacing them 8-16 feet apart, depending on the variety. Water newly planted trees thoroughly and apply a balanced fertilizer at planting time. Prune trees annually to maintain their shape and encourage fruit production. Apples are ready to harvest when they reach their full size and the background color changes from green to yellow or red.

Strawberries

Strawberries are an excellent choice for Alaska gardeners, as they are relatively easy to grow and can produce fruit even in the state's cool climate. Varieties like 'Flavorfest', 'Seascape', and 'Fort Laramie' have shown success in Alaska. These strawberries are known for their cold hardiness, disease resistance, and sweet flavor.

To grow strawberries in Alaska, select a location with well-drained soil and full sun. Plant strawberries in early spring or fall, spacing them 12-18 inches apart. Water newly planted strawberries thoroughly and apply a balanced fertilizer at planting time. Strawberries may take 2-3 years to reach full production but will continue to produce fruit for many years with proper care. Harvest strawberries when they reach their full size and turn a deep red color.

Grains

Alaska's climate is well-suited for growing a variety of grains, including barley, oats, and wheat. These crops prefer cool temperatures and can be grown throughout the state. In fact, Alaska has a long history of grain production, with some varieties, like 'Yukon Gold' barley and 'Alpowa' wheat, specifically bred for the state's climate.

To grow grains in Alaska, select a location with well-drained soil and full sun. Plant grains in early spring, following the specific planting instructions for each variety. Space plants according to the specific requirements of each grain. Keep the soil consistently moist, and apply a balanced fertilizer every 4-6 weeks. Harvest grains when they reach maturity, usually 3-4 months after planting. Thresh the grains to remove the seeds, and store them in a cool, dry place for use throughout the year.

In Alaska, the key to successful gardening is selecting the right crops for the climate and providing them with the care they need to thrive. By choosing cold-hardy and disease-resistant varieties, and by using techniques like row covers, cold frames, and greenhouses, gardeners can extend the growing season and increase their chances of success. With careful planning and a little creativity, Alaska gardeners can cultivate a diverse range of crops, from vegetables and fruits to grains and even some tropical plants in greenhouses.
