🌱 How to Care for Dwarf Bearded Iris to Prevent Thrips?

💧 How to Water

Water moderately in spring while the plant is actively growing, allowing the soil to dry almost completely between waterings. Reduce watering significantly during summer dormancy to avoid rhizome rot.

☀️ Lighting

Provide full sun for at least 6 hours a day; strong light is essential for abundant flowering. Partial afternoon shade is tolerated in very hot climates.

🪴 Ideal Soil

Use well-draining, gritty or loamy soil with a neutral to slightly acidic pH. Plant rhizomes at or just below the soil surface -- burying them too deep encourages rot.
