March is the perfect time to start planting summer-flowering bulbs in the UK. As the soil begins to warm up, bulbs can establish themselves and be ready to bloom in the warmer months. Choosing the right bulbs ensures a spectacular display of colour and fragrance throughout the summer. Here are some of the best summer bulbs to plant in March:

1. Dahlias
Dahlias are a fantastic choice for vibrant summer gardens. Available in a range of colors and sizes, they can add structure and beauty to borders and beds. Plant tubers in well-drained soil in a sunny spot, around 10-15 cm deep. In colder areas, it may be wise to start them in pots indoors and move them outside after the last frost.

2. Gladioli
Gladioli produce striking, tall flower spikes that are perfect for cutting gardens. Plant corms in well-drained soil, about 10-15 cm deep and 10 cm apart, in a sunny location. Stagger planting every few weeks until early summer for a continuous display of blooms.

3. Lilies
Lilies offer elegance and fragrance, making them a popular summer choice. Asiatic, Oriental, and Trumpet lilies are all great options. Plant bulbs about 10-15 cm deep in well-drained soil, ensuring they receive plenty of sunlight. Consider planting in containers to move them around for best visual impact.

4. Begonias
Begonias thrive in both containers and garden beds, producing bright and long-lasting flowers. These bulbs prefer partial shade and rich, well-drained soil. Start tubers indoors in pots in March and transfer them outside after the risk of frost has passed.

5. Crocosmia
Crocosmia, also known as Montbretia, is a hardy summer bulb with arching stems and fiery red, orange, or yellow flowers. Plant corms 8-10 cm deep in well-drained soil in a sunny or partially shaded location. They are easy to grow and naturalize well.

6. Eucomis (Pineapple Lily)
Eucomis, or Pineapple Lily, is an exotic-looking plant that thrives in sunny, well-drained areas. Plant bulbs 10-15 cm deep in borders or pots for an eye-catching summer display.

7. Freesias
Freesias are known for their delightful scent and delicate blooms. These bulbs thrive in pots or well-drained beds with full sun exposure. Plant 5 cm deep and enjoy their wonderful fragrance throughout summer.

Planting Tips

• Soil Preparation: Ensure soil is well-draining and enriched with compost or organic matter.
• Frost Protection: Some bulbs are sensitive to frost; starting them indoors can help protect young shoots.
• Watering & Feeding: Keep soil moist but not waterlogged. Apply a balanced fertilizer for healthy growth.

By planting these summer bulbs in March, you can enjoy a stunning garden filled with color and fragrance all summer long. Happy gardening!
