1.Proper soil preparation is crucial for planting bulbs successfully. Well-draining, loose soil enriched with compost or leaf mold. Ensure excellent drainage; if your soil is clay-heavy, mix in some coco peat.
2.Ensure the bulbs receive 4 to 6 hours of sunlight daily, adjusting the light exposure according to the specific variety some prefer partial shade while others require full sun.
3.Plant bulbs at a depth two to three times their height (e.g., a 2 cm bulb goes 4–6 cm deep) with spacing depending on size, typically 5–15 cm apart.
4.Water lightly after planting, keep soil moist but not waterlogged during growth, and reduce watering after flowering to let foliage yellow and bulbs enter dormancy. 5.Apply a low-nitrogen, high-potassium fertilizer when shoots emerge and post-bloom.
6.Avoid cutting green leaves immediately after flowering to allow energy storage.
7.Prevent pests and diseases by avoiding overwatering and treating bulbs with neem oil or mild fungicide before planting.
8.Store bulbs off-season by cleaning, drying in shade, and keeping them in breathable containers at 10–20°C with moisture absorbers; avoid sealed plastic and humid conditions.

Description
Iris Tectorum also known as "roof iris" for its traditional placement on Asian thatched roofs, Iris Tectorum is a hardy perennial prized for its architectural foliage and vibrant spring blooms. This compact variety reaches 12–18 inches, showcasing delicate violet-blue flowers with white crests nestled within dense clumps of lance-shaped, ribbed leaves. The glossy, upright foliage emerges in fan formations directly from the ground, creating textural interest even after flowering concludes. A key advantage: the flower stems persist year-round, eliminating the need for post-bloom pruning.
Flowering spans February–April in plains and March–May in hilly terrain. For optimal establishment, plant between October and November. This versatile, low-maintenance perennial combines ornamental appeal with practical durability, making it an excellent choice for gardeners seeking reliable seasonal color.
Environment
Grow fortnight lilies in light, dappled shade to nearly full sun. Once established, fortnight lilies tolerate poor, dry soils, but do best in a well drained soil with regular watering during the growing season.
Iris reach optimum growth when protected from afternoon sun and planted in garden soil with good drainage.
It is very versatile and can be planted in various mediums from moderately dry soils to wetlands.Plants grow to 4 or 5 feet tall in standing water, making it ideal for water gardens and wet soil.They reach about 2 to 3 feet in soil.
Cut the spent blooms off of the spike to encourage rebloom on the same stalk.
Landscape Use
Great in pots as well as gardens, the Japanese Iris is also used around water and as a feature softening rock landscaping.
