Louisiana iris

Louisiana irises like their soil kept lightly moist and should be watered with about 2-3 inches of water once or twice a week during the growing season, which is typically April to October. Water should be applied evenly to the entire root zone and allowed to soak in before applying more. Be sure to discontinue watering once temperatures drop in October and resume in April.

Louisiana iris (Iris 'Professor Neil') prefers bright, indirect sunlight for the best performance and blooms. This means it should get about 4 hours of sunlight a day, preferably in the morning or late afternoon. It would be best to keep it away from direct afternoon sunlight to avoid scorching the foliage. If planted in part shade, this flower will still bloom, but probably not as abundantly as it would in its preferred conditions of higher light.

Pruning Louisiana Iris (Iris 'Professor Neil') should be done annually in late winter or early spring, before the plant sends out new growth. Pruning should be kept minimal to maintain the natural shape of the plant. Dead or discolored leaves and foliage should be removed, as should any damaged or broken stems or stalks. Flowers that have been spent should also be removed. It is also beneficial to remove any damaged or overcrowded rhizomes and roots. Pruning should not be done once new growth has begun and the plant is actively blooming. Pruning should also not be done in extreme hot or cold weather.
