Gardening in Zone 2 presents unique challenges and opportunities. With its short growing season and cold winters, selecting the right seeds and planting at optimal times is crucial for a successful garden. This planting calendar provides guidance on the ideal seeds to start each month, helping gardeners maximize their harvests and enjoy a thriving garden year-round.
Understanding Zone 2
Zone 2 is characterized by very cold winters with average minimum temperatures ranging from -40°F to -30°F (-40°C to -34°C). The growing season is short, typically lasting from late May to early September. Due to these conditions, gardeners need to plan carefully, starting seeds indoors early and choosing hardy varieties that can withstand the cold.
January: Planning and Indoor Starts
January is the perfect time to plan your garden and start seeds indoors. Focus on hardy vegetables and herbs that can be transplanted later or harvested early.
- Herbs: Parsley, thyme, chives
- Vegetables: Broccoli, cauliflower, cabbage
- Seeds to start indoors: Tomatoes, peppers, eggplants (if you have a heated indoor space)
February: Early Seed Starting
In February, continue indoor seed starting and prepare your garden beds. You can also start cool-season crops outdoors if the soil is workable.
- Indoor: Lettuce, kale, Swiss chard
- Outdoor (if soil is workable): Peas, radishes, spinach
- Seeds to start indoors: Tomatoes, peppers, eggplants
March: Early Transplanting
By March, start hardening off indoor seedlings and transplanting cold-tolerant plants outdoors. Keep an eye on the weather forecast for late frosts.
- Transplant outdoors: Cabbage, broccoli, cauliflower seedlings
- Plant directly outdoors: Peas, radishes, carrots
- Continue indoor starts: Tomatoes, peppers
April: Main Planting Month
April marks the beginning of the main planting season. Hardy vegetables can be planted directly outdoors, and indoor seedlings are ready for transplanting.
- Direct sow outdoors: Peas, carrots, beets, turnips, lettuce
- Transplant outdoors: Cabbage, broccoli, cauliflower, kale
- Indoor: Tomatoes, peppers, eggplants
May: Peak Planting Time
May is ideal for planting warm-season crops and finishing indoor starts. Be mindful of the last frost date in your area.
- Plant outdoors: Beans, corn, squash, cucumbers, melons
- Transplant: Tomatoes, peppers, eggplants
- Continue sowing: Basil, herbs, leafy greens
June: Maintenance and Succession Planting
In June, focus on maintaining your garden, watering, and mulching. You can also sow successive crops for a continuous harvest.
- Succession planting: Lettuce, radishes, carrots
- Watering: Keep soil moist, especially during dry spells
- Mulching: Helps retain moisture and suppress weeds
July: Peak Harvest and Continued Planting
July is harvest time for many crops. Continue planting quick-growing vegetables for a fall harvest.
- Harvest: Beans, cucumbers, tomatoes, herbs
- Plant for fall: Kale, broccoli, Brussels sprouts
- Water regularly: Ensure plants are well-watered during hot weather
August: Preparing for Fall
August is the time to start planning for fall crops and sowing seeds indoors for a late-season harvest.
- Indoor sowing: Lettuce, spinach, radishes
- Outdoor planting: Cover crops or late-season greens
- Harvest: Tomatoes, peppers, herbs
September: End of Season and Preparation
September signals the end of the main growing season. Focus on harvesting remaining crops and preparing your garden for winter.
- Harvest: Root vegetables, hardy greens
- Clean up: Remove plant debris to prevent pests and diseases
- Soil preparation: Add compost and cover with mulch
October to December: Garden Cleanup and Planning
During the colder months, focus on garden cleanup, soil improvement, and planning for the next year. Protect perennial plants and consider extending your growing season with cold frames or greenhouses.
By following this planting calendar, gardeners in Zone 2 can enjoy a productive and rewarding gardening experience despite the challenging climate. Proper timing and hardy plant choices are key to success.
