Gardening made easy - How and when to plant Iris rhizomes

Gardening with Kids - Plant Iris rhizomes easy enough for kids gardening

Plant iris rhizomes in late August or September when nighttime temperatures range between 40 and 50 degrees Fahrenheit. This is an ideal planting time, as the rhizomes have time to settle in the soil and get established before winter. Iris rhizomes can also be planted in spring or early summer, but try to avoid planting them very late in the fall, as they may not overwinter very well.
