Don’t panic if your peony buds are crawling with ants. It may look alarming, but it’s actually one of the most common—and most misunderstood—sights in the garden. In most cases, the ants aren’t harming your peonies at all.
Here’s what’s really happening.
Why Are Ants Attracted to Peony Buds?
Peony buds produce tiny droplets of sweet nectar on the outside of their buds, known as extrafloral nectaries.
These sugary secretions are a food source for ants, so the insects gather around the buds to feed.
They’re interested in the nectar—not the flower itself.
Are the Ants Hurting Your Peonies?
The answer is no.
Ants don’t chew the petals, eat the buds, or damage the plant.
In fact, while feeding on the nectar, they often chase away insects that might actually harm the flower buds, creating a mutually beneficial relationship between the ants and the peony.
Do Peonies Need Ants to Bloom?
This is one of the biggest gardening myths.
No—peonies do not need ants to open.
The flowers will bloom perfectly well without them.
Ants are simply taking advantage of the sugary nectar produced by the buds.
Should You Spray the Ants?
In most situations, no.
Because the ants aren’t damaging the plant and may even help protect the buds from other insects, there’s usually no reason to use insecticides.
The ants will naturally disappear once the flowers finish blooming and the nectar is gone.
How to Bring Peonies Indoors Without Ants
If you’re cutting peonies for a bouquet, you probably don’t want the ants coming inside too.
Here’s what to do:
- Cut the flowers outdoors.
- Hold each stem upside down and gently shake it.
- Rinse the buds lightly with water if needed.
- Inspect the blooms before arranging them in a vase.
This removes most ants without harming the flowers.
When Should You Be Concerned?
Seeing ants alone is not a problem.
However, inspect the buds if you notice:
- Brown or black spots
- Mold or fuzzy gray growth
- Deformed buds
- Buds that fail to open
- Visible damage from other insects
These symptoms are usually caused by diseases or different pests—not by ants.
Other Reasons Peonies May Not Bloom
If your peonies aren’t flowering, ants are almost certainly not the reason.
More common causes include:
- Too little sunlight
- Planting too deeply
- Too much nitrogen fertilizer
- Immature plants
- Improper pruning
- Damage from disease
Fixing these growing conditions is far more important than worrying about the ants.
Common Myths About Ants on Peonies
Myth: Ants eat the flower buds.
False. They’re feeding on nectar outside the buds.
Myth: Peonies can’t bloom without ants.
False. Peonies open naturally whether ants are present or not.
Myth: Ants should be killed immediately.
False. They’re temporary visitors and are generally considered beneficial in the garden.
Final Thoughts
If you notice dozens of ants covering your peony buds, take it as a sign that your plant is doing something completely natural.
The ants are simply collecting sweet nectar produced by the buds, and in return they may help discourage other insects from feeding on the flowers.
So instead of reaching for insect spray, let nature do its job. Once your peonies open, the ants will move on—and you’ll be left with the beautiful blooms you’ve been waiting for.
