Planting Siberian Iris

Siberian Iris are hardy plants, growing in zones 3-9. When selecting a place to plant Siberian iris bulbs, look for a space that is in direct sun or partial shade (4 or more hours of direct sunlight daily). They prefer slightly acidic, moist, well-drained soil, but will tolerate wet soil. Siberian Iris look best when planted in groups of three or more.

How to Plant Siberian Iris

Siberian Iris bulbs are planted in the spring. To ensure the best selection, many gardeners buy Siberian Iris in the winter or early spring. Before planting, mix compost into the soil to improve the soil. Dig a hole large enough to accommodate the rhizome. Plant the rhizome so the eyes are just below the surface. Space Siberian Iris about 18-24 inches apart. Water after planting.

Siberian Iris are low-maintenance, deer-resistant perennials and have few disease and pest problems. To keep them looking their best, fertilize them once a year with an all-natural, slow-release fertilizer like Van Bourgondien 100% Natural Perennial Food.

When Do Siberian Iris Bloom

Siberian Iris bloom in the early summer, after German Iris and Dutch Iris. Many iris lovers plant Siberian Iris bulbs to extend the iris season.

When to Divide Siberian Iris

Siberian Iris will form large, well-established clumps, usually several years after planting. While division isn't always necessary, watch the plants. If the plants become crowded or if the flowering decreases, then plan to divide your Siberian Iris plants.

When to Transplant Siberian Iris

The best time to divide and transplant Siberian Iris is either in early spring when the plants are just starting to show signs of growth or the summer, immediately after the plants flower. After dividing Siberian Iris, keep the roots moist until transplanting.
