watering

Border bearded irises should be watered deeply and regularly during their bloom season (May-June). During this time, they should be watered once every 7-10 days. When watering, make sure to slowly and gently direct the water to the base of the plant, and avoid wetting the foliage if possible. During the summer months of July and August, reduce watering to once per month. After flowering season has ended (September), gradually stop watering your irises until the ground freezes in winter.

sunlight

Border bearded iris (Iris 'Rielle') should receive full sun (6-8 hours) per day to thrive. A minimum of 6 hours of sunlight per day is ideal, generally spread out through the morning and afternoon, but not overbearing midday heat. Consider providing some shade in the middle of the day depending on the climate.

pruning

Border Bearded Iris (Iris 'Rielle') should be pruned twice a year - once in the spring and once in the fall. In the spring, after the iris blooms, remove the flower stalks as close to the soil as possible. Also, remove any dead or diseased foliage. Pruning during this time will ensure that the new growth has the best chance of developing and blooming. In the fall, once the foliage has begun to decline and just before winter arrives, prune off the entire stalk down to the soil. This ensures that the plant is well maintained and can receive adequate nourishment and sunlight throughout the winter and bloomed abundantly in the spring. Doing this will also help keep the plant healthy for future growth.
