How to Divide Bearded Irises: Tips and Tricks

Bearded irises are beautiful, showy flowers that come in a range of colors and varieties. These hardy perennials are easy to grow and maintain, but eventually they will need to be divided. Dividing your bearded irises is an important part of keeping them healthy and blooming year after year. In this article, we'll walk you through the steps of how to divide bearded irises, including when and how to do it, what tools you'll need, and tips for success.

When to Divide Bearded Irises

The best time to divide bearded irises is in late summer or early fall, after they have finished blooming for the season. This gives the plants plenty of time to establish roots before winter sets in. If you wait too long to divide them, the plants may not have enough time to recover before the cold weather arrives.

If you notice that your bearded irises are overcrowded or not blooming as well as they used to, it may be time to divide them. Overcrowding can lead to poor growth and weak blooms, so it's important to give your irises enough space to thrive.

How to Divide Bearded Irises

Dividing bearded irises is a simple process that can be done with just a few tools. Here's what you'll need:

• Garden gloves
• A digging fork or shovel
• Pruning shears or scissors
• Bleach or rubbing alcohol (optional)

Once you have your tools ready, follow these steps:

1. Start by digging up the clump of bearded irises. Use a digging fork or shovel to carefully loosen the soil around the plant, being careful not to damage the rhizomes.
2. Once the plant is out of the ground, shake off any excess soil and trim back the foliage to about 6 inches.
3. Separate the rhizomes by gently pulling them apart. You may need to use pruning shears or scissors to cut through any tough roots that connect them.
4. Inspect each rhizome for signs of disease or damage. If you notice any soft spots, brown areas, or other signs of rot, cut them away with a clean pair of scissors or pruners. If you're concerned about spreading disease, you can dip your tools in bleach or rubbing alcohol between cuts.
5. Once you've removed any diseased or damaged parts, replant the healthy rhizomes. Dig a hole about 8 inches deep and wide enough to accommodate the rhizome. Place the rhizome in the hole with the top facing up, and cover it with soil. Be sure to leave about one-third of the rhizome above the surface of the soil.
6. Water the newly planted irises thoroughly to help settle the soil and remove any air pockets.

Tips for Success

Dividing bearded irises is a relatively simple process, but there are a few things you can do to ensure success:

• Make sure you're dividing the right kind of iris. Bearded irises have thick, fleshy rhizomes that are easy to separate. Other types of irises, such as Siberian or Japanese irises, have different types of root systems and may require different methods of division.
• Don't divide your irises too often. While it's important to divide them when they become overcrowded, dividing them too frequently can weaken the plants and reduce their ability to bloom.
• Label your newly planted irises. When you replant your bearded irises, be sure to label them with the variety name and planting date. This will help you keep track of which plants need to be divided in the future.
• Give your irises plenty of sun and water. Bearded irises need at least six hours of direct sunlight per day and regular watering to thrive.

Bearded irises add color and texture to any garden.

Dividing bearded irises is an important part of keeping these beautiful flowers healthy and blooming year after year. With the right tools and techniques, anyone can successfully divide their irises and enjoy the rewards of a vibrant, colorful garden. Just remember to give your irises plenty of sun, water, and room to grow, and you'll be rewarded with stunning blooms for many seasons to come.
