After you plant your irises, give them a thorough watering. If conditions are dry, water every 7 to 10 days or as needed during the morning or evening. Assuming you planted your irises in the late summer or early fall, you may stop watering your plants as soon as the weather cools and it begins raining or snowing. One common mistake to avoid with your irises is over-watering. If the rhizome or roots are held in contact with moisture without being given a chance to drain, root rot can set in. This fungal condition can be potentially fatal for the iris and easily spreads to nearby plants, so prevention is key. Over time, your plant will require less and less watering on your part. Once the weather takes a turn for the cooler in the fall, you can stop watering until the next summer growing season. In general, your iris should require less watering with each subsequent summer — for climates with mild summers, it's possible The exception here is for areas with very hot, dry summers. In these cases, some watering may be necessary every summer to keep the iris from drying out. Though irises are quite durable, they can't survive in extreme conditions without help. As the iris grows, you'll want to periodically check to make sure that the rhizome hasn't become covered with dirt, organic matter, or other debris. If it has, gently brush it off without moving the plant itself or disturbing its roots. In addition, make sure that the soil still has good aeration and drainage — if it doesn't, add humus or organic matter as needed. Unlike high-maintenance garden plants, iris leaves don't require pruning or trimming for good growth. In fact, leaving the leaves undisturbed even after the growing season allows the iris to gain more nutrients from photosynthesis for next year's growth. In general, the only sort of trimming you should need to do for iris leaves is to remove brown, dead leaf tissue that has already died — this provides no benefit to the plant. Note that, before winter, you may also want to cut the flower stalk to its base. If the flower dies during winter and falls at the base of the plant, it can cause rot to spread to the rhizome as it decays.
