As seasoned gardeners in the Valley, we've learned that the key to a successful harvest often lies in the preparation, so in this blog, we'll uncover our best seed starting tips for Alaska! Whether you're a budding green thumb or a gardening guru, mastering the art of seed starting can level up your growing game and provide you with abundant harvests for months to come.

If you're ready for some serious spring planting, let's dig into these indoor seed starting tips for spring.


Why You Should Start Seeds Indoors 

It's no secret that here in Alaska we have one of the shortest growing seasons in the country, so having a solid planting strategy is key for growing food in the Valley.  At Ken's Garden Center, we know that indoor seed starting is an important part of this strategy as our region's frigid temperatures and late frosts pose challenges for tender seedlings.



Starting seeds indoors provides a crucial head start for gardeners in Alaska, allowing you time to nurture plants until outdoor conditions improve. It also extends the growing season (which we'll take any day!), particularly for warm-season vegetables such as tomatoes and peppers. Indoor cultivation offers green thumbs like us control over growing conditions and ensures optimal development despite weather extremes.


Ultimately, indoor seed starting empowers Alaska gardeners to overcome climatic hurdles, maximizing harvests and fostering a deeper connection to the land in this rugged landscape.


Getting Started: What are the Best Plants to Grow in the Mat Su Valley?


Now is the perfect time to kickstart your gardening journey by starting seeds indoors. Here in the Valley, our unique climate presents both challenges and opportunities, and selecting the right plants for indoor cultivation is crucial for a successful harvest. 


The top contenders for indoor seed starting are broccoli, cauliflower, cabbage, tomatoes, peppers, and eggplant. These resilient crops not only thrive in Alaska's climate but also offer a diverse range of flavors and textures to enhance your culinary adventures!


  • Broccoli: Varieties like 'Gypsy' and 'Green Sprouting Calabrese' are well-suited to the Valley’s cool temperatures and short growing season.

  • Cauliflower: Look for cold-hardy varieties such as 'Snow Crown' and 'Snowball Y Improved' for optimal results.

  • Cabbage: Consider 'Golden Acre' and 'Red Express' for their ability to withstand chilly temperatures and produce crisp, flavorful heads.

  • Tomatoes: Indeterminate varieties like 'Alaska' and 'Polar Star' thrive in Alaska’s extended daylight hours, producing abundant fruits with rich flavor.

  • Peppers: Opt for compact varieties such as 'King of the North' and 'Hungarian Yellow Wax' for prolific yields in your indoor garden.

  • Eggplant: Varieties like 'Black Beauty' and 'Fairy Tale' excel in containers and thrive in the warmth of indoor environments.


Nurturing Your Seedlings: Indoor Seed Starting Tips for Mat Su Valley


Providing optimal conditions for your seedlings is essential for healthy growth and robust plants. Here are some tips to guide you along the way:


  • Light: Position your seed trays near a south-facing window or supplement with grow lights to provide adequate light for seedling development. Aim for 14-16 hours of light per day to promote strong, sturdy growth.

  • Watering: Keep soil consistently moist but not waterlogged to prevent damping off and other fungal diseases. Water from the bottom to encourage strong root development and avoid disturbing delicate seedlings.

  • Temperature: Maintain temperatures between 65-75°F during the day and slightly cooler at night to mimic ideal growing conditions. Use a heating mat or thermostat-controlled heat source to ensure consistent warmth for optimal germination and growth.

In addition to providing proper lighting, watering, and temperature conditions, monitoring your seedlings closely for signs of stress or nutrient deficiencies is essential. Keep an eye out for leggy growth, yellowing leaves, or wilting, and adjust care practices accordingly to ensure your plants thrive.


Transplant Preparation


As your seedlings mature, it's crucial to prepare them for transplanting into the garden. Harden off your plants by gradually exposing them to outdoor conditions, starting with a few hours of direct sunlight and increasing exposure over several days. This process helps acclimate seedlings to the rigors of the outdoor environment, reducing the risk of transplant shock and ensuring a smooth transition to the garden bed.



As we eagerly anticipate the arrival of warmer days here in Alaska, we hope these indoor seed starting tips get you geared up for the growing season. Now is the perfect time to prepare for success by starting your seeds indoors! By selecting the right plants, providing optimal care, and nurturing your seedlings to maturity, you can set the stage for a thriving garden in the months to come.
