As summer approaches, the arrival of peonies with their delicate pink petals and subtly sweet fragrance signals the season’s beginning. However, gardeners should be aware of a potential threat: ants.
Peonies are highly valued for their beauty and romantic associations. Unfortunately, these flowers are also attractive to ants due to the sweet nectar produced by their buds, which provides essential sugars for the insects. Once an ant discovers a peony, it releases a pheromone that attracts the rest of its colony, leading to a sudden swarm.
Contrary to a common myth that ants help peonies bloom, they actually have a symbiotic relationship. Ants feed on the nectar and, in return, protect the peony from other pests such as aphids and caterpillars. This protective behavior can be beneficial, but it comes with risks.
Experts from DIY Everywhere caution that if left unchecked, ants can spread and cause problems in other parts of the garden. Ants dig deep into the soil, potentially damaging plant roots and causing dehydration. They can also bury low-lying plants with their soil mounds.
To manage the number of ants on peony buds, a balanced approach is recommended. One effective method is to gently remove ants using a soft brush or a gentle stream of water, avoiding damage to both the ants and the petals. Natural repellents like cinnamon or mint can also be used, with the added benefit of repelling other pests such as rats and foxes.
Maintaining a clean garden by removing debris like fallen twigs and leaves is crucial, as these can serve as habitats for ants. Additionally, encouraging the presence of beneficial insects like ladybirds and lacewings can help control pest populations without relying on ants.
However, it is important to avoid using pesticides, as they can disrupt the natural balance and harm beneficial insects and soil health. DIY Everywhere warns against the use of such chemicals, emphasizing the need to protect the garden’s ecosystem.
In summary, while ants can play a role in protecting peonies, gardeners must manage their presence carefully to prevent damage to other plants and maintain a healthy garden environment.
