Growing Guide & Care Tips

• Planting: Plant bulbs in spring after the last frost, spacing them about 10-15cm apart at a depth of 8-10cm. Choose a sunny spot with fertile, well-drained soil.
• Watering: Water regularly during dry spells but avoid waterlogged conditions. Mulch lightly to conserve moisture.
• Feeding: Apply a balanced fertiliser at planting and again as flower spikes develop.
• Support: In exposed sites, consider staking taller stems to prevent wind damage.
• Aftercare: Cut back faded flower spikes but allow foliage to die back naturally before removing—this helps feed the bulb for next year’s display.

Design & Companion Planting Ideas
