Alaska gardeners succeed with vegetables bred for rapid growth in extended daylight conditions. If you are searching for the best vegetables to grow in alaska, you need crops that thrive in cool soil and long summer days. This guide covers top picks for your far-north garden.
Alaska’s growing season is short but intense. The sun barely sets in June, giving plants extra energy. You can harvest impressive yields if you choose the right varieties.
Cold nights and sudden frosts are real challenges. But with smart planning, your garden can be very productive. Let’s look at what works best.
Best Vegetables To Grow In Alaska
These vegetables are proven winners for Alaskan conditions. They mature quickly and handle temperature swings. Each one has specific tips for success.
Cold Hardy Greens
Leafy greens are the easiest start for new gardeners. They grow fast and tolerate light frost. You can sow them directly in the ground as soon as the soil thaws.
- Kale: Siberian and Red Russian varieties are very cold tolerant. They actually taste sweeter after a frost. Harvest outer leaves for weeks.
- Spinach: Choose varieties like ‘Tyee’ or ‘Space’. They resist bolting in long days. Plant in early spring and again in late summer.
- Swiss Chard: Bright Lights is a colorful choice. It handles cool soil well. You can pick leaves when they are small for salads.
- Lettuce: Loose-leaf types like ‘Black Seeded Simpson’ mature in 45 days. Avoid head lettuce which takes too long.
Root Vegetables
Root crops love Alaska’s loose, cool soil. They store well for winter use. Most can be planted as soon as the ground is workable.
- Radishes: ‘Cherry Belle’ is ready in 25 days. Plant small batches every week for continuous harvest.
- Carrots: Short varieties like ‘Nantes’ or ‘Danvers’ do best. Long carrots may struggle in rocky soil. Keep soil moist for sweet roots.
- Beets: ‘Detroit Dark Red’ is reliable. Both roots and greens are edible. Thin seedlings to give room for bulbs.
- Turnips: ‘Purple Top White Globe’ matures in 50 days. They grow fast and tolerate light frost well.
Brassicas
Cabbage family plants thrive in cool weather. They need consistent moisture and fertile soil. Many varieties were developed for northern climates.
- Broccoli: ‘Packman’ or ‘Green Goliath’ produce side shoots after the main head. Harvest before flowers open.
- Cabbage: ‘Early Jersey Wakefield’ forms small heads quickly. It resists splitting in wet conditions.
- Cauliflower: ‘Snow Crown’ is a fast grower. Blanch heads by tying leaves over them when they start to form.
- Brussels Sprouts: ‘Jade Cross’ matures in 90 days. Start indoors early for best results.
Peas And Beans
These legumes fix nitrogen in the soil. They prefer cool starts but need warmth to flower. Choose early maturing types for Alaska.
Snow peas are a great choice. ‘Oregon Sugar Pod II’ produces flat pods in 60 days. Pick them before seeds swell.
Shelling peas like ‘Alaska’ or ‘Wando’ are named for northern gardens. They handle light frost and produce well.
Bush beans are better than pole beans. ‘Provider’ and ‘Contender’ mature in 50 days. They do not need support structures.
Potatoes
Potatoes are a staple in Alaskan gardens. They grow well in cool soil and long days. You can store them for months after harvest.
Plant certified seed potatoes in late May. Cut them into pieces with at least two eyes each. Space them 12 inches apart in rows.
Early varieties like ‘Yukon Gold’ or ‘Red Norland’ mature in 70 days. They produce good yields even in short seasons.
Hill soil around plants as they grow. This protects tubers from sunlight. Harvest after vines die back in fall.
Tips For Alaskan Garden Success
Follow these practical steps to improve your harvest. Small changes can make a big difference in northern gardens.
Start Seeds Indoors
Many vegetables need a head start. Begin seeds indoors 4-6 weeks before last frost. Use grow lights to prevent leggy plants.
Hardening off is important. Move seedlings outside for a few hours each day. Increase time gradually over a week.
Transplant on a cloudy day to reduce shock. Water well after planting. Cover with row covers if frost is forecast.
Use Season Extenders
Cold frames and cloches protect plants. They warm soil and block wind. You can plant two weeks earlier with them.
Row covers are lightweight fabric. They let light and water through but keep frost off. Use them on cold nights in spring and fall.
Raised beds warm up faster than ground soil. They also drain better in wet Alaskan springs. Build them 6-8 inches high.
Choose The Right Location
Find a spot with full sun. South-facing slopes are ideal. Avoid low areas where cold air settles.
Wind protection is critical. Plant near a fence or building. Use windbreak fabric if needed.
Test your soil pH. Most vegetables prefer 6.0-7.0. Add lime if soil is too acidic. Add sulfur if too alkaline.
Water And Mulch Properly
Alaskan summers can be dry. Water deeply once a week rather than shallowly daily. This encourages deep roots.
Mulch with straw or grass clippings. It keeps soil cool and moist. It also suppresses weeds.
Drip irrigation is efficient. It puts water right at plant roots. It reduces leaf diseases from overhead watering.
Common Challenges And Solutions
Every Alaskan gardener faces these issues. Here is how to handle them without stress.
Short Growing Season
Choose vegetables with short days to maturity. Look for 45-70 day varieties. Avoid anything over 90 days unless started indoors.
Use succession planting. Replace harvested crops with new seeds. This maximizes your short window.
Plant cold-tolerant crops first. Peas, spinach, and kale can go in as soon as soil is workable. Warm season crops go in later.
Cool Soil Temperatures
Soil warms slowly in Alaska. Use black plastic mulch to heat soil. It can raise temperature by 5-10 degrees.
Wait until soil is at least 50°F for most seeds. Use a soil thermometer to check. Cold soil causes seeds to rot.
Warm season crops like beans need 60°F soil. Plant them in late May or early June. Use cloches for extra warmth.
Pests And Diseases
Cutworms are common in spring. Place cardboard collars around seedlings. They prevent worms from cutting stems.
Slugs love cool, wet conditions. Use beer traps or diatomaceous earth. Hand pick them at night.
Powdery mildew appears in late summer. Space plants for good air flow. Avoid overhead watering.
