Japanese peonies are sometimes considered sensitive. Therefore, you shouldn't pull out the scissors and get to work without some background knowledge. Read more about how to cut them correctly below!
How do I cut a Japanese peony correctly?
Japanese peonies should not be cut down completely in autumn. Remove old, weak and flowering shoots in spring or autumn. If necessary, you can cut the shoots back to the first bud in autumn to limit growth and promote a compact shape.
Don't cut it down completely in autumn
As a rule, when we talk about Japanese peonies, we are talking about so-called tree peonies, also known as shrub peonies. Such peonies last for several years and are now usually grafted. In contrast to perennial peonies, these specimens are not completely cut down in autumn.
Sometimes a cut is necessary
Tree peonies like the Japanese peony do not need pruning. Over time, scissors should still be used from time to time. You should remove shoots that are too old, weak, slow to bloom, or crossing each other. The best time for this is in the spring before budding. Alternatively, the cleaning cut can be done in autumn.
But scissors should not only be used to remove unwanted shoots. Wilted flowers should also be cut off to protect the plant. Otherwise the seed production will cost you a lot of energy.
If necessary: cut back only to the bud in autumn
If you think your Japanese peony could use a pruning to get back into shape, you can easily prune it back. This can stop growth and promote a compact shape.
In autumn, take a pair of sharp secateurs (€14.00 on Amazon) and cut the shoots back to the first bud. That is enough! When you cut off the buds, you also remove the flowers for the next season!
Other reasons why a cut may be appropriate
Even then a cut makes sense:
- for obtaining cuttings for propagation
- to remove frozen shoots
- to remove diseased plant parts
Tip
Since these plants are prone to gray mold, you should clean the cutting tool well after each use to avoid disease transmission!
