watering

Water your Spuria Iris (Iris 'Adriatic Blue') deeply but infrequently. This plant does not like to be overwatered, so this is an important point. Water your plant until the soil is completely saturated once per week during the growing season (spring through summer). During the fall and winter months, reduce the frequency to once every 2 weeks. Avoid getting water on the leaves as this may cause them to rot. If you are using a sprinkler, make sure the system is set to a low setting that is not strong enough to damage the plants.

sunlight

Iris 'Adriatic Blue' (spuria iris) enjoys full sun for at least 6-8 hours per day in order to flourish. This plant should be placed in an area with full sun in the morning and light shade in the afternoon, although bright shade is sometimes acceptable. For optimum performance, especially during warm summer days, it is best to protect Iris 'Adriatic Blue' from direct midday sun.

pruning

Pruning for Iris 'Adriatic Blue' (Spuria Iris) should be done on an as-needed basis. In general, removing dead, damaged, or overgrown foliage can be done throughout the growing season. In early spring like most irises, dead foliage should be removed. Once the plant begins to bloom in mid to late spring, remove the spent blooms to encourage reblooming and to help the plant stay tidy. In fall, cut all foliage back to the ground. This promotes healthy new growth and may also encourage reblooming in the fall.
