- Spacing: Space the rhizomes about 18 to 24 inches apart, to allow for proper growth and air circulation.
- Planting Depth: Plant the rhizomes with the tops just below the soil surface, about 2 to 3 inches deep.
- Watering: Water the newly planted rhizomes thoroughly, and continue to keep the soil consistently moist throughout the growing season. Avoid letting the soil dry out completely.
- Mulching: Apply a 2 to 3-inch layer of organic mulch, such as wood chips or shredded bark, around the plants to help retain moisture and suppress weeds.
- Fertilizing: Fertilize your Japanese iris in early spring with a balanced, slow-release fertilizer, or use a water-soluble fertilizer every 4 to 6 weeks during the growing season.
- Deadheading: Regularly remove spent blooms to encourage continued flowering and prevent seed formation, which can exhaust the plant.
- Dividing: Every 2 to 3 years, divide the rhizomes in early spring or fall to maintain vigorous growth and encourage abundant blooms.
