Setup: Planting Instructions
1. Memilih Lokasi
Select a site that receives penuh matahari (at least 6 hours of direct sunlight daily). While Iris Germanica can tolerate partial sun, full sun promotes the best blooming. Ensure the soil is well-drained. Irises do not thrive in soggy conditions, which can lead to rhizome rot.
2. Soil Preparation
Prepare the soil by loosening it to a depth of 12-15 inches. Amend heavy clay soils with organic matter like compost or peat moss to improve drainage. For sandy soils, organic matter will help retain moisture and nutrients. The ideal soil pH for irises is slightly acidic to neutral (6.0 to 7.0).
3. Planting the Rhizome
The best time for planting is in the musim bunga. Dig a shallow hole, creating a small mound of soil in the center. Place the iris rhizome on top of the mound, spreading the roots down into the soil. The top of the rhizome should be partially exposed or just barely covered with soil. If planting multiple irises, space them 12-24 inches apart to allow for air circulation and growth.
- Unpack your potted iris carefully.
- Remove the plant from its pot, gently loosening any circling roots.
- Place the plant in the prepared hole, ensuring the top of the rhizome is at or just below the soil surface.
- Backfill with soil, firming gently around the plant.

Operating: Care and Maintenance
1. Menyiram
Water thoroughly after planting. Once established, irises are relatively drought-tolerant. Water regularly during dry periods, especially during bloom time, but avoid overwatering. Allow the soil to dry out between waterings.
2. Fertilizing
Apply a low-nitrogen fertilizer (e.g., 5-10-10 or 6-10-10) in early spring and again after blooming. Avoid high-nitrogen fertilizers, which can promote lush foliage at the expense of flowers and may encourage rhizome rot.
3. Deadheading and Pruning
Remove spent flower stalks by cutting them back to the base after blooming to prevent seed formation and encourage the plant to put energy into rhizome growth. Keep foliage intact until it yellows naturally in the fall, as it helps nourish the rhizome for the next season's blooms. In late fall, cut back yellowed or diseased foliage to about 6 inches to reduce overwintering pests and diseases.
4. Pest and Disease Management
Monitor for common iris pests like iris borers and diseases such as bacterial soft rot. Good air circulation, proper drainage, and sanitation (removing dead foliage) are key preventative measures. Treat specific issues with appropriate organic or chemical controls if necessary.
5. Bahagian
Irises benefit from division every 3-5 years, typically in late summer to early fall, after blooming. This helps maintain vigor and flowering. Dig up the rhizomes, discard old or diseased sections, and replant healthy, younger rhizomes.
