There is something majestic and magical about the Bearded Iris.
The only color that cannot be found in this beautiful flower is bright red. The bulbs are easy to plant, and they can spread rather quickly. These perennials are hardy in US Zones 3-9, needing a freeze so they can go dormant.
They need to be planted in late summer or early fall. The Iris like a sunny spot with at least six hours of full sun to help to keep the rhizomes dry. They grow best in a neutral soil and only need granular fertilizer a couple of times a year. The best times to feed them is in the early spring and after they bloom. It's best to plant them about 16-18 inches apart for good air circulation. They do not need mulching because constant moisture will rot the rhizomes. To preserve the energy of the plant, remove the seed pod that forms after they have bloomed.To ensure a healthier plant, prune back the foliage in the fall.
Bearded Iris should be divided every three to four years if they are thickly clustered. Dividing should be done in late summer. Rhizomes, their root structure, can die off as new ones form to cause crowding and slow the blooms from forming. Dividing them will give the plants new ground for growth.
To divide the plants, use a garden spade or fork, carefully lifting them out of the soil trying to avoid damaging the rhizomes. Slowly pull the plants apart using your hands while examining them for dead or damaged rhizomes. Use a knife to separate baby rhizomes from the parent, making sure the knife has been sanitized with ten percent bleach water between cuts. Discard any damaged or diseased plant parts. Replant, fanning the roots, and leaving a portion of the rhizome exposed. Space the plants about 12 to 18 inches apart, clipping the tops down to 4-6 inches.
