ðą How to Care for Bearded Iris to Prevent Grey Mould?
ð§ How to Water
Water deeply every 7-10 days during spring and summer. Reduce watering significantly in fall and winter. Always water at the base â never overhead â to prevent fungal diseases. Rhizomes should sit slightly exposed to sunlight at the soil surface.
âïļ Lighting
Requires at least 6-8 hours of direct sunlight daily for abundant blooming. In shadier spots, flowering will be sparse or absent. Position in south- or west-facing beds for maximum sun exposure.
ðŠī Ideal Soil
Use well-draining, slightly alkaline to neutral soil (pH 6.5-7.5). Avoid compacted clay soils; amend with coarse sand or grit if needed. Do not mulch over rhizomes as this can cause crown rot.
