Siberian iris

Siberian iris (Iris 'Lady of Quality') should be watered regularly during the growing season, preferably in the early morning or evening so as to avoid midday evaporation. In spring when the weather is warm and the plant is actively growing, water about every 5-7 days during dry weather. During hot and dry summer months water at least 2-3 times per week. In fall, reduce watering to about once a week and during winter, suspend watering altogether except for special occasions like warm spells when the soil shows signs of drying. When watering, make sure to provide a thorough soak or the equivalent of an inch or 2 of rain water at once. Avoid frequent but shallow watering as this leads to shallow roots which may make the plant less resistant to drought and frost.

Siberian iris (Iris 'Lady of Quality') requires direct sunlight for at least 6-8 hours a day, especially during the early part of the day. They can definitely tolerate full sun, but some afternoon shade may be beneficial in areas with very hot summers. They enjoy a slightly acidic soil and a well-drained location. Regular watering is necessary during the summer; during the winter, water sparingly to allow the plant to go dormant.

Siberian iris (Iris 'Lady of Quality') should be pruned in mid-spring, generally around mid to late April, once new growth has emerged. Pruning should begin by remove overcrowded or damaged foliage and dead stems. Older outer stems should be cut back to 6-10 inches above the soil. This will allow new growth to emerge in the center of the plant. Pruning will also help promote flowering and a bushier habit.
