Louisiana iris

Louisiana Iris should be watered deeply and infrequently. In mid-spring and early summer, when the plant is actively growing and flowering, give it 1 inch of water per week. During the summer months, when days are hotter, reduce watering to every other week. In the late summer and fall months, when the iris’s foliage begins to die back, reduce watering to about once a month. In the winter, Louisiana iris should not be watered since it is dormant.

Louisiana iris (Iris 'Black Gamecock') blooms best in bright sunlight for at least 6 hours daily, though it will tolerate partial shade. During the summer months it is best to provide shade in the mid-afternoon when temperatures and sunlight are at their peak. During the cooler months of spring and fall, it can be grown in full sun.

Louisiana iris (Iris 'Black Gamecock') should be pruned at the end of the blooming season once the blooms have finished and the stalks have turned brown. This should be done in late July or August to prepare the plants for dormancy. Pruning should involve removing any dead leaves or foliage, any dead flower stalks and any flower buds that have not yet bloomed. Pruning should be done carefully, however, as it is important not to disturb any of the buds for the next bloom season. Pruning should also involve trimming back the leaves to about 8-10 inches above the ground. This should help to keep the plant looking neat and healthy while encouraging it to store up energy for the bloom season ahead.
