They can be found near streams, streams, wetlands, and the edges of wet meadows. This sturdy plant is easy to grow in a home garden pond.

Picking a Spot for a Blue Flag Iris Plant

It is best to plant a blue flag iris pond plant in a large pond basket or plastic pot to limit its growth since, like some other water iris types, such as yellow flag irises, can spread rapidly and become difficult to control.

If you don’t live in a hot desert climate, look for a place where the plant can be exposed to the sun most of the day. If that is the case, some afternoon shade can be beneficial.

Soil 

These pond plants love highly acidic and moist soil with high amounts of organic material- such as compost and mulch. 

Propagate Blue Flag Iris

To keep your plants under control, divide them after flowered every 2-3 years.

Fertilize

Blue iris pond plants should be fertilized regularly during the growing season with a general-purpose aqua fertilizer to promote the healthy growth of roots and foliage. You can also use an aquatic fertilizer that is balanced and slow-releasing.

In warmer climates, the water iris is green throughout the year. However, any yellow or brown leaves should not be left behind to maintain the plant’s health and water quality. If you live in a cold climate, cut water iris just above the waterline in autumn.

Every year, repot the blue iris pond plants in a slightly larger container.
