As spring progresses in Zone 3, gardeners are eager to start planting their favorite vegetables and flowers from seed. May is a crucial month for seed starting, offering the opportunity to grow a variety of top-performing varieties that thrive in cooler temperatures. This guide highlights the best seeds to start now and tips for successful gardening in Zone 3.
Why Start Seeds in May?
Starting seeds indoors or in protected outdoor beds in May allows plants to establish strong roots before the heat of summer. It also extends the growing season, giving you earlier harvests and a wider selection of crops. In Zone 3, with its short growing season, timely seed starting is essential for success.
Top Varieties to Plant Now
Vegetables
- Tomatoes: Start early indoors, then transplant outside once the danger of frost has passed. Varieties like ‘Early Girl’ and ‘Brandywine’ perform well.
- Cucumbers: Sow directly in the garden or start indoors for an earlier harvest. Look for ‘Marketmore’ or ‘Lemon’ varieties.
- Peppers: Start indoors now for transplanting later. Popular choices include ‘Jalapeño’ and ‘Bell’ peppers.
- Beans: Sow directly into the soil once the soil warms up. Bush beans like ‘Provider’ are reliable.
- Zucchini and Summer Squash: Sow directly outside after the last frost for a bountiful summer harvest.
Flowers
- Marigolds: Easy to grow from seed, they add color and help deter pests.
- Zinnias: Sow directly in the garden for vibrant blooms throughout summer.
- Cosmos: Start indoors for early blooms, or sow directly into the soil.
- Sunflowers: Sow directly outside for tall, cheerful flowers.
- Petunias: Start indoors for a longer flowering season.
Seed Starting Tips for Zone 3
Growing in Zone 3 requires attention to the short growing season and cooler temperatures. Here are some tips to maximize your success:
- Use cold frames or row covers: Protect young plants from late frosts.
- Start seeds indoors: Use grow lights and ensure proper watering and ventilation.
- Choose early-maturing varieties: Look for seeds labeled for short growing seasons.
- Harden off seedlings: Gradually expose indoor-started plants to outdoor conditions before transplanting.
- Monitor soil temperature: Ensure soil is warm enough for direct sowing, typically above 50°F (10°C).
Conclusion
May is an ideal time to start a variety of vegetables and flowers in Zone 3. With careful planning and the right varieties, you can enjoy a productive and colorful garden season. Happy planting!
