As a seasoned gardener, you've likely come across the task of dividing perennials.

Why Divide Perennials?
Perennials, by definition, live for more than two years. However, even the hardiest perennials can become pot-bound, leading to reduced growth and productivity. Division is a simple and effective way to revive these plants, allowing them to thrive once again.
Some signs that it's time to divide your perennials include:
- Overcrowding: If your perennial plants are growing too densely, it's time to give them some space.
- Reduced growth: If your perennials are not producing as many flowers or foliage as they used to, it may be a sign that they need to be divided.
- Dead or damaged growth: If you notice dead or damaged growth on your perennial plants, it's a good opportunity to divide them.
When to Divide Perennials
The best time to divide perennials depends on the type of plant and your location. In general, it's best to divide perennials during their dormant period, which is usually in the fall or early spring.
Fall Division
Fall is an excellent time to divide perennials because the plants are dormant, making them more manageable. Plus, the cooler temperatures and increased moisture help to reduce stress on the plants during the division process.
Spring Division
Spring is another excellent time to divide perennials. As the plants begin to grow, they're already producing new growth, making the division process less stressful.
Late Summer Division
Late summer is also a great time to divide perennials, especially those that bloom in the summer. By dividing the plants before they go to seed, you can encourage new growth and more blooms in the following year.
How to Divide Perennials
Dividing perennials is a relatively simple process, but it does require some care and attention. Here's a step-by-step guide to help you get started:
Gather Your Tools
- Gardening gloves
- Trowel or garden fork
- Pruning saw (optional)

Prepare the Area
- Clear the area around the perennial plant of any debris or obstructions.

Remove the Soil
- Gently loosen the soil around the perennial plant, taking care not to damage the roots.
- Use a trowel or garden fork to carefully remove the soil, creating a trench around the plant.

Replant the Division
- Once the division is complete, replant the new sections of the perennial, making sure the roots are well-established in the new soil.
- Water the plant thoroughly to settle the soil.
- Apply a layer of compost or soil amendment to help the plant recover from the division process.
