How to Plant, Grow and Care for Irises

Irises are perennials that bloom in the spring, offering vibrant colors and a unique shape.

Iris Overview

There are over 300 species of irises. Popular types include Bearded, Siberian, and Japanese irises.

Choosing Your Iris

Choose a sunny location with well-drained soil. Irises enjoy at least 6 hours of direct sunlight daily.

Ideal Location

Plant the bulbs (rhizomes) 1-2 inches deep in the soil with the tops exposed.

Planting Irises

Space the iris rhizomes about 1-2 feet apart to give them room to grow.


Keep the soil slightly moist but never waterlogged. Overwatering can lead to root rot.


Feed your irises with a balanced fertilizer in early spring and again in late summer.


Divide your irises every 2-4 years in late summer to keep them healthy and vibrant.

Dividing Irises
