watering
Iris robusta 'Gerald Darby' requires regular watering to keep the soil consistently moist, but not soggy. Water the plant when the top inch of soil feels dry. During its active growing period in spring and summer, apply enough water to moisten the soil down to a depth of at least 6 inches. During the fall and winter, reduce the watering frequency to every couple of weeks, allowing the soil to dry between applications. During periods of exceptionally dry weather, it may be necessary to water more frequently.
sunlight
Iris (Iris robusta 'Gerald Darby') requires at least 6 hours of direct sunlight each day in order to thrive. This species of iris grows best when exposed to direct sunlight from mid-morning to mid-afternoon, with a bit of dappled shade in the afternoon. Too much direct sunlight can cause the leaves to scorch and the flowers to fade. Placing this plant in a windy location will also help it to receive adequate amounts of sunshine to aid in its growth.
pruning
Iris robusta 'Gerald Darby' should be pruned late, usually after the first bloom cycle in late spring or early summer. For best results, only prune out dead, diseased, and damaged branches, which should be cut at a 45 degree angle just above a healthy budding side shoot. You can also remove flower stalks after blooming if desired. To keep the plant fuller, lightly prune back main stems of the plant by no more than 1-third of their total length and individual weak branches by up to 2-thirds of their length. This will encourage new growth and keep the plant looking full and healthy.

It's important to keep the soil evenly moist and water when the soil dries out slightly. Be sure to fertilize the irises with a balanced fertilizer every month during the growing season for best results.
