FAQs
When is the best time to plant these bulbs?
These bulbs are best planted in the autumn or early spring, depending on your local climate, to ensure they establish roots before the blooming cycle.
Can I leave these bulbs in the ground year-round?
Yes, they are hardy perennials and are designed to stay in the ground to return each spring.
Do I need to fertilize them?
While they thrive in fertile soil, a balanced bulb fertilizer applied in early spring can encourage more vigorous blooms.
How deep should I plant the bulbs?
A general rule of thumb for irises is to plant them so the tops of the rhizomes are just barely covered by soil.
Are these deer resistant?
While many irises are less favored by deer, it is always recommended to use protective netting or deterrents if you have high deer traffic.
How long do the flowers last as cut flowers?
With clean water and regular trimming of the stems, they typically last for 5 to 7 days in a vase.
Troubleshooting
Poor flowering or stunted growth
Check soil drainage; Iris bulbs can struggle and rot in heavy, waterlogged soil. Ensure they are planted in a sunny, well-draining spot.
Bulbs beginning to sprout while in storage
Ensure storage conditions are cooler and darker. If sprouting has already occurred, plant the bulbs immediately in pots or the garden.
Flowers appearing smaller than 60cm
Ensure they are receiving adequate sunlight. Lack of light can lead to 'leggy' or undersized growth as the plant stretches for the sun.

Setup, Compatibility & Care
For the best results, plant these bulbs in fertile, well-drained soil during the recommended planting season. Ensure the site receives full sun or partial shade. If you are not planting immediately, store the bulbs in a cool, dry, and well-ventilated location that is strictly frost-free. Once planted, they require minimal care; simply remove spent blooms to keep the display tidy and allow the foliage to die back naturally in late summer so the bulb can recharge its energy stores for the next season. They are compatible with most companion plants that share similar moisture and sun requirements.
