WaterSiberian Irises, including 'Fourfold White', typically prefer consistently moist soil during their growth period. They should be watered once a week with about an inch of water, equivalent to roughly 0.623 gallons per square yard of soil. The key is to allow the soil to dry slightly between waterings, but not to become completely dry. During hot or dry spells, increase watering frequency to maintain moisture levels. In winter or when the plant is dormant, reduce watering to prevent waterlogged soil, which can lead to root rot.
LightThe Siberian Iris 'Fourfold White' thrives in full sun to partial shade. The ideal spot for this plant would be an area that receives at least six hours of direct sunlight daily, but it can also perform well with some afternoon shade. Avoid deep shade locations, as this can lead to poor flowering and weak growth.
TemperatureSiberian Irises are hardy plants and 'Fourfold White' can tolerate a wide range of temperatures, ideally growing between 68°F and 86°F. They can survive minimum winter temperatures down to -40°F and summer highs up to 104°F. However, they perform best when the temperature remains within the moderate range of their ideal growing conditions.
PruningPruning Siberian Iris 'Fourfold White' involves removing dead or damaged foliage and spent flower stalks to promote healthy growth and improve the plant's appearance. Prune in late fall or early spring before new growth starts. Typically, this plant is pruned once a year, and the best time for pruning is after the blooming period, in early summer, to allow time for the plant to gather energy for the next season's growth.
CleaningAs needed

Life cycleThe Iris 'Fourfold White' (Siberian Iris) begins its life cycle as a seed, typically requiring a period of stratification or cold treatment to break dormancy before germination can take place in the spring. Once the seed germinates, it develops into a seedling, which progressively grows and produces narrow, grass-like leaves. Over time, the plant forms a clump with an expanding root system known as a rhizome, a characteristic growth pattern for irises. The plant reaches maturity and generally blooms in late spring to early summer, displaying prominent white flowers with four-fold symmetry. After blooming, the flowers are followed by the formation of seed pods, which eventually dry and release seeds to complete the reproductive cycle. In late autumn, the Siberian Iris dies back to the rhizome, entering a period of dormancy over the winter months, and resuming growth again when the conditions become favorable in the spring.
PropogationPropogation time
Spring to summer
Propogation: The Siberian Iris 'Fourfold White' can be best propagated by division, a process typically carried out in the late summer after the blooming period has ended or in early fall. To divide the plant, carefully dig around the clump, trying to cause minimal disturbance and to preserve as many roots as possible. Once lifted from the ground, use a sharp knife or spade to cut through the rhizomes, ensuring that each section has at least one healthy fan of leaves and a portion of roots. Replant the divisions promptly, keeping the rhizome just at or slightly below the soil surface. Water the new plantings thoroughly to help establish them. This method allows the iris to recover and become established before the onset of winter, promoting a robust return in the spring.
