May is a pivotal month for gardeners in Zone 1, marking the beginning of the planting season for many flowers. Starting seeds indoors or directly sowing them outdoors can lead to a vibrant and colorful garden throughout the summer and fall.
Understanding Zone 1
Zone 1 is characterized by very cold temperatures, often dropping below -50°F (-45°C) during winter. Short growing seasons and late springs mean that selecting hardy flowers is essential for successful cultivation.
Best Flowers to Start in May
In Zone 1, the following flowers are suitable for seed starting in May:
- Sunflowers – Hardy and easy to grow, they add height and cheerfulness to gardens.
- Marigolds – Resistant to cold and pests, perfect for early planting.
- Cosmos – Tolerant of cooler temperatures, they bloom abundantly in summer.
- Black-eyed Susans – Native and resilient, they thrive in full sun.
- Four O’Clocks – Bloom in late summer and are tolerant of cooler nights.
Seed Starting Tips for Zone 1
To ensure successful growth, follow these tips:
- Start seeds indoors in a warm, well-lit area to extend the growing season.
- Use seed-starting trays with drainage to prevent waterlogging.
- Maintain soil moisture but avoid overwatering.
- Gradually acclimate seedlings to outdoor conditions before transplanting.
- Plant outdoors only after the last frost date, typically late May or early June.
Additional Considerations
Due to the short growing season, choosing quick-growing varieties and providing protection during unexpected cold snaps can improve success. Using row covers or cold frames can help shield tender seedlings.
Conclusion
May is an excellent time to start flowers in Zone 1, focusing on hardy, early-season varieties. Proper planning and care will result in a beautiful, thriving garden that brings color and life to your outdoor space all season long.
