Water generously after planting: 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 autumn, 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 autumn, you can stop watering until the next summer growing season. In general, your iris should require less watering with each subsequent summer. 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.
Trim brown or dying leafs and the flower stalk: 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.
Weed/Pest control in spring: As new plants begin to sprout up, keep a keen eye out for any weeds near your irises and pull them out as early as possible. Use environmentally-friendly herbicides or weed killers to keep grasses and weed away from the bases of your irises. In addition, you’ll want to be wary of any encroaching pests, especially slugs. There are many, many ways to bait slugs, from commercial products to improvised home solutions. One very easy way to do this is to make a beer trap — fill a wide-mouthed jar halfway up with beer and bury it up to the rim of the jar in the soil. Slugs, attracted to the beer, will fall in and drown.
Give fertiliser/nutrients in spring: Irises can benefit from the occasional light application of fertiliser starting the growing season after you plant it. Don’t use a fertiliser high in nitrogen as this can cause excessive foliage growth that will eventually rot. A teaspoon of a slow release fertiliser like Osmocote 90 is adequate. Water after applying your fertiliser to avoid fertiliser ‘burn’.
