The Siberian iris is an easy-to-care-for beardless flower that grows on long, thin stems to a height of 1- to 3-feet tall. The Siberian iris makes for a perfect water garden or pond plant, because it loves constant moisture. This iris blooms in late spring and develops deep rhizome roots. If you provide the right care and fertilizer, your Siberian iris will be long-lived and grow beautifully. Select a spot for your Siberian iris along the edge of your pond or water garden that is in full to partial sunlight.
Prepare a fabric planter pot made from porous polypropylene. Fill the pot with a mixture of equal parts peat moss, organic compost and commercial potting soil made for acid-loving plants.
Remove the Siberian iris from its container and gently loosen the outer roots. Plant the iris into the fabric pot so that the potting mix covers the tops of the roots well.
Top off the fabric pot with 2 inches of organic mulch.
Place the Siberian iris in its fabric pot on a shallow shelf at the edge of your pond. Ensure that only one-half to two-thirds of the pot is submerged in the water.
Feed your Siberian iris once per year in early spring with an all-purpose flower fertilizer. Follow the dosage instructions on the label.
