Siberian iris

Siberian iris (Iris 'Ego') requires evenly moist soil. Water deeply once a week during the growing season and then cut back to once every 2 weeks during the dormancy period in summer. In hot climates, water more frequently to prevent the soil from drying out. If necessary, add a layer of mulch around the plant to help retain moisture.

Siberian iris (Iris 'Ego') requires full sunlight to bloom optimally. It prefers to be in direct sunny locations for at least 6 hours each day from late spring to early summer to grow and flower properly. For best results and to ensure that blooms will come back the following year, this plant should be placed in a spot that gets direct sunlight in the morning and afternoon for a minimum of 6 hours a day for several months. Even in the winter it requires some sunlight, so during the colder months it should be placed somewhere that receives a few hours of sunlight each day.

Siberian iris (Iris 'Ego') should be pruned in early spring, after flowering has finished. The clumps of foliage should be cut back to 4-6 inches above the soil to remove any dead or diseased foliage. Any excess flower stalks should also be trimmed off at this time. This will help encourage healthy growth and will also reduce the risk of the plant becoming overcrowded. After pruning, fertilize the plant with a balanced fertilizer and water thoroughly.
