Peonies are one of the most beloved perennials in the flower - gardening world. Their large, fragrant blooms can transform any garden into a paradise. If you're looking to have more flowers and increase your peony plant collection, dividing peonies is an excellent strategy. In this step - by - step guide, we'll walk you through the process of dividing peonies to achieve these goals.

First, let's understand why dividing peonies is beneficial. Over time, peony plants can become overcrowded. When they are overcrowded, they have to compete for nutrients, water, and sunlight. This competition can lead to fewer blooms and less healthy plants. By dividing peonies, you give each new plant more space to grow and thrive, which results in more abundant flowers.

The best time to divide peonies is in the fall, usually around September or October. At this time, the plants are starting to go dormant, and the shock of division is less likely to harm them. Before you start dividing, gather all the necessary tools. You'll need a sharp spade or garden fork, a pair of pruning shears, and some well - drained soil and compost for replanting.

Step 1: Prepare the Plant
Start by cutting back the peony foliage to about 2 - 3 inches above the ground. This makes it easier to work with the plant and reduces the risk of disease. Use your pruning shears to make clean cuts. Make sure to dispose of the cut foliage properly, as it could harbor pests or diseases.

Step 2: Dig Up the Peony
Use your spade or garden fork to carefully dig around the peony plant. Start about 8 - 10 inches away from the base of the plant and dig down about 12 - 15 inches. Be gentle as you dig to avoid damaging the roots. Once you've loosened the soil around the plant, carefully lift the peony out of the ground. You may need to use some force, but try not to break the roots.

Step 3: Clean the Roots
Shake off as much soil as possible from the roots. You can also use a gentle stream of water to wash away the remaining soil. This will make it easier to see the root structure and identify the eyes (the small, pinkish buds on the roots). The eyes are where new growth will emerge, so it's important to keep them intact.

Step 4: Divide the Peony
Look for natural divisions in the root system. You can use your hands to gently pull the roots apart at these divisions. If the roots are too tough to pull apart, you can use a sharp knife or pruning shears to make clean cuts. Each division should have at least 3 - 5 eyes and a healthy root system. Smaller divisions may take longer to establish and produce blooms.

Step 5: Replant the Divisions
Choose a location for replanting that gets at least 6 - 8 hours of sunlight per day and has well - drained soil. Dig a hole that is wide and deep enough to accommodate the roots of the division. Place the division in the hole, making sure the eyes are no more than 2 inches below the soil surface. Backfill the hole with a mixture of soil and compost, and gently firm the soil around the plant. Water the newly planted division thoroughly.

Step 6: Care for the New Plants
After replanting, keep the soil moist but not waterlogged. Mulch around the plants to help retain moisture and suppress weeds. In the first year after division, the peonies may not produce many blooms as they are focusing on establishing their root systems. But in the following years, you'll be rewarded with more plants and more beautiful flowers.

Dividing peonies is a rewarding activity that not only allows you to expand your peony collection but also ensures the health and vitality of your plants. With a little patience and the right techniques, you can enjoy a garden full of peonies with large, fragrant blooms for years to come.
