PLANTING and AFTERCARE GUIDE
Best Planting Time
Spring: Plant Iris ‘Lune et Soleil’ in spring to give the rhizomes time to establish strong roots before the blooming period. This early start promotes healthier growth and more abundant flowers during the season.
Late Summer to Early Autumn: Alternatively, plant Iris ‘Lune et Soleil’ in late summer or early autumn. This gives the rhizomes time to root before entering dormancy, setting the stage for vigorous growth the following spring.
Site Selection
Sunlight: Choose a sunny location that receives a minimum of 6 hours of direct sunlight daily. Iris requires full sun to produce its most vibrant and prolific blooms.
Soil Conditions: Iris prefers well-drained soil with a neutral to slightly alkaline pH. Avoid heavy clay or waterlogged areas, as excessive moisture can lead to rhizome rot. Improve drainage by adding grit or compost if needed.
Planting Instructions
Prepare the Area: Loosen the soil and remove weeds. Mix in organic compost or well-rotted manure to enhance soil structure and fertility.
Positioning Rhizomes: Plant your Iris rhizomes horizontally with the top of the rhizome just visible above the soil surface. Space them about 30 cm apart to allow for air circulation and future growth.
Backfilling and Watering: Gently firm the soil around the rhizome and water lightly. Ensure good drainage from the start to prevent standing water.
Watering Requirements
Establishment Phase: Water Iris ‘Lune et Soleil’ regularly during the first few weeks after planting. Allow the soil to dry out slightly between watering sessions.
Mature Plants: Once established, Iris is drought-tolerant. Water only during prolonged dry spells and avoid overwatering, which may cause rhizome rot.
Feeding
Spring Feeding: In early spring, apply a low-nitrogen, high-phosphorus fertiliser to promote root development and flower production.
Post-Bloom Feeding: After flowering, feed your Iris again to replenish nutrients and support next year’s blooms.
Pruning and Maintenance
Deadheading: Remove spent flowers promptly to encourage continued blooming and prevent seed formation, which diverts energy from the rhizomes.
Post-Season Care: Cut back foliage in autumn once it begins to yellow. This helps prevent disease and keeps your garden looking tidy.
Mulching and Protection
Spring Mulch: Apply a light mulch in spring to suppress weeds and retain moisture, but keep it away from direct contact with rhizomes to avoid rot.
Winter Care: In colder months, a thin layer of dry mulch can protect the roots from harsh temperatures. Remove this mulch in early spring as new growth emerges.
Dividing Iris ‘Lune et Soleil’
Every 3–4 years, divide Iris ‘Lune et Soleil’ rhizomes to maintain plant health and flower productivity. Do this in late summer after flowering. Replant the healthiest divisions and discard any soft or diseased rhizomes.
Final Tips
For long-lasting impact, pair Iris ‘Lune et Soleil’ with perennials that offer contrasting textures or complementary colours. Whether planted in formal beds, mixed borders, or cottage-style gardens, Iris ‘Lune et Soleil’ rewards gardeners with show-stopping blooms and minimal upkeep.
