Iris Hollandica Mysterious Rainbow Collection (25 bulbs)

Planting & Care Instructions

Dutch irises are elegant spring- to early summer-flowering bulbs ideal for garden borders, pots and cut flower arrangements. For the best flowering results, choose a suitable location and follow the recommended planting depth for high-quality bulbs.

• Planting time: Plant the bulbs in autumn, from September to December, before the ground freezes. Flowering time generally occurs from May to June.
• Position & soil: Choose a full sun position. Plant in loose, fertile and well-drained soil. Avoid areas where water tends to collect.
• Planting depth & spacing: Place the bulbs with the pointed end facing upwards. For Dutch iris bulbs, size 8+ cm, plant approximately 8–10 cm deep and 8–10 cm apart.
• Watering: Water once after planting to settle the soil. Additional watering during autumn is usually unnecessary. Avoid waterlogged soil.
• Growing in containers: Use pots or balcony boxes with drainage holes and a well-drained potting mix. Bulbs can be planted slightly closer together than in garden beds.
• After flowering: Remove faded flowers, but allow the foliage to remain until it naturally turns yellow and dies back. This allows the bulb to store energy for the following season.
• Returning each year: Dutch irises are winter-hardy perennials that can naturally return and bloom year after year when left in suitable growing conditions.
