Plant irises in late summer or early autumn, when overnight temperatures are 4°C to 10°C or higher. This gives them plenty of time to settle in before the winter arrives. Because tall bearded iris cultivars go dormant in early to mid-summer, it’s better to plant them closer to fall.

If you received bare rhizomes or irises in a container earlier in the year, plant them as soon as you get the opportunity. It’s preferable to get them in the ground sooner rather than later.

It’s critical to have good drainage all year; irises love “wet feet but dry knees.” In the winter, they will not tolerate moist soil.

Using a tiller or garden fork, loosen the soil to a depth of 12 to 15 inches, and then add a 2- to 4-inch layer of compost.

Plant the rhizome horizontally with the top exposed for bare-root irises. Plant the rhizome just below the soil surface in hot-summer settings.

Rhizomes can be planted individually or in groups of three, 1 to 2 feet apart, depending on their size.

Dig a shallow hole with a diameter of 10 inches and a depth of 4 inches. Create a ridge of dirt in the center and set the rhizome on it, spreading roots on both sides. Fill the hole with earth and gently firm it, leaving a portion of the rhizome and leaf exposed.

Tip: It’s all too easy to plant irises too deeply. In warmer climates, these plants’ rhizomes should be partially exposed to the elements or lightly covered with soil. They won’t thrive if they’re buried too deeply.

Mulch should not be used around the rhizome because it encourages rot.

Thoroughly wet the area.
