Peony buds covered in ants? Here’s why and what you should do next

Peonies are beloved for their lush, fragrant blooms and are a staple in many gardens. However, gardeners often notice ants swarming over the buds of these plants. This phenomenon can be puzzling and sometimes concerning for those unfamiliar with the natural relationship between peonies and ants. Understanding why ants are attracted to peony buds and how to manage them is essential for maintaining a healthy garden.
Understanding the Relationship Between Peonies and Ants
The relationship between peonies and ants is a classic example of mutualism, where both parties benefit from the interaction. While it may seem like the ants are harming the peonies, they are actually part of a natural process that helps the plants thrive. This symbiotic relationship has evolved over time, with ants being drawn to the sweet nectar produced by the peony buds.
Reasons Why Ants Are Attracted to Peony Buds
Ants are primarily attracted to peony buds due to the presence of nectar, which serves as a food source for them. Additionally, ants can act as protectors for the peonies, deterring other pests that might harm the plant. Environmental factors and the potential role of ants in pollination also contribute to their attraction to peony buds.
1. Presence of Nectar on Peony Buds
Peony buds secrete a sugary substance known as nectar, which is highly attractive to ants. This nectar is produced by extrafloral nectaries, which are glands located outside of the flowers. The nectar provides a rich source of carbohydrates for ants, making peony buds an appealing destination for them.
2. Ants as Natural Protectors
In exchange for the nectar, ants offer a form of protection to the peony buds. They can deter other insects that might damage the plant, such as aphids or caterpillars. By patrolling the buds, ants help to keep these harmful pests at bay, indirectly benefiting the peonies.
