Siberian iris

Siberian iris (Iris 'Chilled Wine') enjoys moist soil but display a higher resistance to drought than other iris species. During the growing season, water your Siberian iris thoroughly once a week, ensuring that the soil remains evenly moist at all times. In very warm or sunny climates, additional water may be needed. During the winter months, only water the Siberian iris occasionally (once every 2 to 3 weeks) enough to keep the soil from completely drying out. Keep the mulch around the plant damp during the colder months. Aim to keep the soil evenly damp rather than soaked, to avoid root rot.

Siberian iris (Iris 'Chilled Wine') grows best in full sun to partial shade. Full sun is best for maximum blooming. Morning sun is ideal, as the afternoon sun may be too intense. The plant does need some shade in hot climates to prevent stress on the foliage in summer. Generally, Siberian iris will thrive in 6-8 hours of direct sunlight per day. If the plant is located in an area where sunlight is limited, light filtered through a curtain could help provide enough light for the plant.

Siberian iris (Iris 'Chilled Wine') should be pruned once a year just as new growth begins in early spring. Lightly prune away any dead or damaged foliage and stems and then carefully trim away excess growth to achieve the desired shape. Heavily pruning Siberian iris can reduce the number of blooms for the following year, so it is best to just trim away excess or overly long stems. Trimming should be done just after the plant blooms in the summer or in the very early spring before new growth begins.
