Propagation of Bearded Irises

Bearded irises are propagated mainly through rhizome division:

• Divide in late summer after flowering season.
• Trim leaves back to 6 inches.
• Replant healthy rhizomes in well-prepared soil.
• Water lightly until new growth appears.

Seed propagation is possible but less common because it takes several years for seedlings to bloom.

Companion Planting with Bearded Irises

Seasonal Care Tips

Bearded irises follow a natural cycle:

• Spring: vigorous growth, blooming, fertilize lightly.
• Summer: dormant after bloom, reduce watering, divide rhizomes if needed.
• Fall: prepare soil for winter, remove dead foliage.
• Winter: minimal care, protect rhizomes in cold climates with mulch.
