It is possible to divide a Bartzella peony. Dividing peonies is a common practice to propagate and rejuvenate these beautiful plants. Bartzella peonies, also known as intersectional or Itoh peonies, are a hybrid cross between herbaceous and tree peonies. They are known for their large, showy flowers and vigorous growth.
When dividing a Bartzella peony, it is important to choose an appropriate time. The ideal time to divide peonies is in the fall, after the foliage has died back. This allows the plant to focus its energy on establishing new roots rather than supporting foliage growth. However, if necessary, peonies can also be divided in early spring before new growth emerges.
To start the division process, carefully dig up the entire clump of the Bartzella peony. Use a garden fork or shovel to loosen the soil around the plant, being cautious not to damage the roots. Once the clump is lifted, gently shake off any excess soil to expose the root system.
Next, examine the clump and identify natural divisions or sections within the plant. Look for areas where you can make cuts to separate the clump into smaller sections. It is important to make clean cuts to minimize damage and promote healthy growth.
When dividing a Bartzella peony, it is recommended to cut the intersecting sections at a thin point between larger sections. This is similar to cutting a ginger root in the kitchen, where you aim to separate a small piece from a larger root. Visualize the cuts that will free up divisions and use a sharp, clean knife or garden shears to make the cuts.
Once you have made the necessary cuts, ensure that each divided section has a good amount of healthy roots and at least one bud or “eye.” The bud is a small, pinkish or reddish growth point on the root crown where new growth will emerge. Divisions without buds may not grow, so it is important to ensure that each section has a bud intact.
After dividing the Bartzella peony, it is time to replant the divisions. Prepare the planting site by loosening the soil and incorporating organic matter, such as compost or well-rotted manure, to improve fertility and drainage. Dig a hole wide and deep enough to accommodate the divided section, ensuring that the bud is planted at the correct depth. The top of the bud should be no more than 1-2 inches below the soil surface.
Place the divided section in the hole and backfill with soil, gently firming it around the roots. Water thoroughly to settle the soil and eliminate any air pockets. Mulch the newly planted divisions with a layer of organic mulch, such as shredded bark or straw, to conserve moisture and suppress weed growth.
In the first year after dividing, it is important to provide regular watering and monitor the newly planted divisions for signs of stress or disease. With proper care and attention, the divided Bartzella peony should establish and grow into a healthy, blooming plant.
Dividing Bartzella peonies not only allows you to propagate new plants but also helps rejuvenate older clumps that may have become overcrowded or less productive. By dividing the plant, you are giving it a fresh start and encouraging vigorous growth and abundant flowering.
I have personally divided several peonies, including Bartzella, in my garden, and it has been a rewarding experience. Watching the divided sections grow into beautiful, blooming plants brings a sense of accomplishment and joy. So, if you have a Bartzella peony that needs dividing, don’t hesitate to give it a try and enjoy the benefits of propagating and rejuvenating this stunning plant.
