🌼 This Is the Best Time to Divide Your Irises: Here’s Why and How

Irises are beloved for their stunning blooms and vibrant colors, making them a staple in many gardens. But did you know that to keep your iris plants healthy, vigorous, and blooming abundantly, you need to divide them regularly?

Dividing irises not only rejuvenates the plants but also prevents overcrowding, reduces disease risk, and helps you propagate new plants to expand your garden. But timing is everything.

Here’s the best time to divide your irises—and a simple step-by-step guide on how to do it right.

🌞 When Is the Best Time to Divide Irises?

The ideal time to divide irises is late summer to early fall, typically 6 to 8 weeks after the irises finish blooming. This timing allows the plants to recover before winter and get established in their new spot by spring.

Why this timing?

  • After blooming, the iris rhizomes (thick underground stems) are mature and ready to be separated.
  • The cooler fall weather reduces transplant shock and gives roots time to grow.
  • Dividing too early in spring can stress the plants or prevent blooming that season.

🛠️ How to Divide Your Irises: Step-by-Step

1. Dig Up the Iris Clump

Carefully dig around the base of the iris plant to lift the rhizomes out of the soil. Use a garden fork or spade to avoid damaging roots.

2. Shake Off Excess Soil

Gently shake off or rinse away the soil to clearly see the rhizomes and roots.

3. Inspect and Trim

Look for healthy rhizomes that are firm and plump. Discard any that are soft, rotten, or diseased. Trim the leaves back to about 6 inches to reduce water loss and make handling easier.

4. Divide the Rhizomes

Use a clean, sharp knife or garden shears to cut the clump into sections. Each section should have at least one healthy fan of leaves and a strong root system.

5. Prepare the Planting Site

Choose a sunny spot with well-drained soil. Irises prefer full sun and soil that doesn’t stay soggy. Amend soil with compost if needed.
