How to Plant Dutch Iris
When to Plant: Plant Dutch iris in the fall, around the same time as tulips and daffodils. For best results, plant the bulbs within a month of receiving them.
Depth and Spacing: Dig a hole 6-8 inches deep and mix in some peat moss or compost to improve drainage. Plant the bulbs pointy end up, about 5 inches deep and 4 inches apart.

- Choose a sunny spot with well-drained soil.
- Amend the soil with compost or manure before planting to improve drainage and fertility.
- Water the bulbs thoroughly after planting.
- Mulch around the bulbs with a layer of bark chips or straw to help keep the soil moist and suppress weeds.
- Dutch iris are relatively low-maintenance plants, but they will appreciate occasional watering and fertilizing during the growing season.
Unique Planting Ideas

- Plant Dutch iris in a rock garden or along a walkway.

Dutch Iris Care
Planting
Plant the bulbs pointy side up 3- to 5-inches deep and 3- to 5-inches apart. Dutch irises thrive in loose, well-drained soil with a slightly acidic pH. If your soil is heavy clay, amend it with sand or compost to improve drainage.
Light
Dutch irises prefer full sun, but can tolerate some shade in the afternoon. In warmer climates, afternoon shade may be beneficial.
Water
Dutch irises need regular watering, especially during the first few weeks after planting and during the flowering period. Allow the soil to dry out slightly between waterings. Avoid overwatering, as this can lead to root rot.
Fertilizer
Fertilize Dutch irises every few weeks with a balanced fertilizer. Stop fertilizing after the flowers have faded.
Pests and Diseases
Dutch irises are susceptible to a few pests and diseases, including leaf spots, mosaic viruses, root rot, and iris borers. However, these problems are usually preventable with proper care.
Propagation
Dutch irises can be propagated by division or by seed. To divide the bulbs, dig them up in the fall and carefully separate them into clumps. Replant the clumps immediately. To propagate by seed, sow the seeds in the fall and water them regularly. The seeds will germinate the following spring.
