In regards to walking iris care, the plant itself requires little in the way of maintenance with exception of providing plenty of moisture. You should water your walking iris regularly during its active growth. Water as needed to keep the soil slightly moist but never soggy. Allow the plant to go dormant in winter and limit its watering to once monthly.
You can feed the plant every two weeks with a water soluble fertilizer in the summer, or use a granular slow release fertilizer annually in early spring as part of your walking iris care. Adding an ample amount of mulch will help with retaining moisture in the soil and insulating plant roots. This will also help with winter protection in suitable areas.
