Nasturtiums are vibrant, easy-to-grow flowers that bring bright colors and edible leaves to gardens. To enjoy continuous blooms throughout the growing season, it’s essential to plant them at the right times of the year. Understanding the optimal planting periods can help gardeners maximize their flowering display.
Understanding Nasturtium Growth Cycles
Nasturtiums are warm-weather annuals that thrive in full sun and well-drained soil. They are sensitive to frost, so timing their planting is crucial. Typically, they are sown after the danger of frost has passed in spring and can continue blooming until the first frost in fall.
The Best Times to Plant Nasturtiums
Spring Planting
For most gardeners, the ideal time to plant nasturtiums is in late spring, once soil temperatures have warmed to at least 55°F (13°C). This usually corresponds to a few weeks after the last expected frost date. Planting in spring ensures a long growing season, resulting in abundant blooms from early summer through fall.
Succession Planting
To maintain continuous flowering, consider sowing new nasturtium seeds every 2-3 weeks during the growing season. This succession planting approach ensures a steady supply of blooms, even as older plants decline or are affected by pests or weather.
Additional Tips for Continuous Blooms
- Plant in a sunny location for optimal flowering.
- Ensure well-drained soil to prevent root rot.
- Water regularly but avoid overwatering.
- Deadhead spent flowers to encourage new blooms.
- Apply a balanced fertilizer sparingly during the growing season.
By planting nasturtiums at the right times and following these care tips, gardeners can enjoy a vibrant, continuous display of flowers throughout the warm months. Their cheerful appearance and edible qualities make them a favorite for many gardens.
