Alaska is not typically known for its corn production, but with the right knowledge and planning, it is possible to grow corn in the Last Frontier. In this article, we will explore when to plant and how to grow corn in Alaska, including the best corn varieties for the state, climate and hardiness zones, planting and harvesting schedules, and answers to commonly asked questions.
Best Corn Varieties for Alaska
Choosing the right corn varieties for Alaska is crucial to ensure a successful harvest. Here are some varieties that have proven to be well-suited for the Alaskan climate:
- Alaska Bush
- Golden Bantam
- Frosty Acres
- Earliglow
These varieties have been specifically developed to withstand colder temperatures and have shorter growing seasons, making them ideal for Alaskan growing conditions.
Alaska Bush corn is a hardy variety known for its ability to thrive in cooler climates. It produces medium-sized ears with sweet, tender kernels that are perfect for fresh eating or canning. This variety is a favorite among Alaskan gardeners for its reliability and excellent flavor.
Golden Bantam corn is a classic heirloom variety that has been a staple in Alaskan gardens for generations. It is known for its deliciously sweet flavor and early maturity, making it a popular choice for gardeners looking to enjoy fresh corn on the cob during the short Alaskan summer.
Climate & Hardiness Zones in Alaska
Understanding the climate and hardiness zones in Alaska is essential for successful corn cultivation. Alaska has a wide range of climates, from frigid arctic regions in the north to more temperate coastal areas in the south.
The state is divided into several hardiness zones, with growing conditions varying widely depending on your location. It is important to know your specific hardiness zone to determine the suitable corn varieties and planting dates for your area.
Alaska’s diverse climate is influenced by its vast size and varied topography. The northern regions experience long, harsh winters with temperatures dropping well below freezing, while the southern coastal areas benefit from milder temperatures due to the moderating effects of the ocean.
When selecting corn varieties for cultivation in Alaska, factors such as days to maturity, cold tolerance, and heat requirements should be carefully considered. For northern regions with shorter growing seasons, early-maturing corn varieties are recommended to ensure a successful harvest before the onset of frost.
When to Plant Corn in Alaska
Knowing when to plant corn in Alaska is crucial for a successful harvest. The general rule of thumb is to plant corn after the last spring frost date, which typically occurs in late May or early June in most parts of Alaska.
Alaska’s unique climate presents challenges for growing corn, but with proper planning and care, it is possible to enjoy a bountiful harvest. The long daylight hours in Alaska during the summer months provide ample sunlight for corn to thrive, but the short growing season requires careful timing.
Here is a step-by-step guide to planting corn in Alaska:
- Choose a well-draining, sunny spot in your garden.
- Prepare the soil by removing any weeds or debris and adding compost or organic matter to improve fertility.
- Sow corn seeds directly into the soil, spacing them according to the recommended planting instructions on the seed packet.
- Cover the seeds with a thin layer of soil and gently water the area.
- Keep the soil consistently moist but not waterlogged throughout the growing season.
- Monitor for pests and diseases and take appropriate measures to protect your corn plants.
- Depending on the variety, corn will typically take 60 to 100 days to mature.
For Alaskan gardeners, selecting short-season corn varieties is essential to ensure a successful harvest before the arrival of fall frosts. Some recommended varieties for Alaska include ‘Northern Xtra-Sweet’ and ‘Arctic Frost,’ which are specifically bred for cooler climates and shorter growing seasons. These varieties have a high sugar content and can mature in as little as 60 days, making them ideal for Alaskan gardens.
Additionally, using black plastic mulch can help warm the soil and promote early growth in colder climates like Alaska. The black plastic absorbs heat from the sun, creating a microclimate that encourages corn plants to establish quickly and develop robust root systems.
When to Harvest or Pick Corn in Alaska
Knowing when to harvest or pick corn in Alaska is crucial to ensure the best flavor and texture. The harvest time for corn will vary depending on the variety and the growing conditions.
Here are some general guidelines to determine when your corn is ready to be harvested:
- Look for the appearance of brown silk on the ears. This is a sign that the ears are pollinated and developing.
- Gently pull back the husk and examine the kernels. They should be plump and filled out.
- Take a taste test! The kernels should be sweet and juicy. If they are starchy, the corn needs more time to ripen.
- Harvest the corn by holding the stalk firmly and pulling downward. Twist the ear slightly to detach it from the stalk.
Once harvested, it’s best to consume corn as soon as possible for the freshest flavor. If you have an excess of corn, it can be blanched and frozen for later use.
Alaska’s unique growing conditions present both challenges and opportunities for corn cultivation. Due to its northern latitude, Alaska experiences long daylight hours during the summer months, providing ample sunlight for corn plants to thrive. However, the cooler temperatures can also slow down the ripening process, requiring growers to be more vigilant in monitoring their corn crops.
When selecting corn varieties to grow in Alaska, it is essential to choose early-maturing types that can reach full maturity within the shorter growing season. Some recommended varieties for Alaskan growers include ‘Northern Xtra-Sweet,’ ‘Polaris,’ and ‘Arctic Frost.’ These varieties have been specifically bred to perform well in cooler climates, ensuring a successful harvest even in challenging conditions.
