When used in garden borders, it can grow quite large and may require dividing to maintain its health and appearance. Proper division not only controls its size but also encourages vigorous growth and more blooms.

Step-by-Step Guide to Dividing Joe Pye Weed
Follow these steps to effectively divide your Joe Pye Weed and maximize space in your border garden.
1. Prepare the Plant
Water the plant thoroughly a day before dividing. This softens the soil and reduces stress on the roots during the process.
2. Dig Around the Plant
Use a garden fork or spade to carefully dig around the base of the plant, about 12-18 inches from the crown. Loosen the soil and gently lift the entire clump out of the ground.
3. Divide the Root Clump
Place the plant on a tarp or work surface. Use pruning shears or a sharp spade to cut the root mass into sections, each with several stems and healthy roots. Aim for divisions around 4-6 inches in diameter for best results.
4. Prepare the Divisions
Remove any damaged or dead roots. Trim back the foliage to about one-third to reduce water loss and stress. Amend the soil in the new planting area with compost for optimal growth.
5. Replant the Divisions
Plant each division at the same depth as it was originally growing. Space divisions 2-3 feet apart to allow for growth and air circulation. Water thoroughly after planting.
