Barb Mrgich, a knowledgeable Penn State Master Gardener from Adams County, offers insights on ant behavior in peonies.
Why Ants Are Attracted to Peonies
Peony buds feature tiny glands called “extrafloral nectaries” that produce nectar, drawing ants to the buds for a sugary treat. Despite the initial concern of seeing ants on your peonies, they do not harm the plant. According to Mrgich, the ants are simply enjoying a snack and do not pose a threat to the peony’s health or blooms. Contrary to popular belief, ants are not essential for peony bud development; they are just there for the nectar.
Natural Pest Control
In addition to feeding on nectar, ants serve a protective role in peonies by warding off harmful pests like thrips. Thrips are small insects that can damage peony buds, leaves, and flowers by feeding on plant sap. Ants, territorial over peony nectar, defend the plant against thrips and other intrusive insects. Mrgich emphasizes the importance of ants as allies in safeguarding peonies from destructive pests, highlighting their role as beneficial caretakers.
Ants Help Your Entire Garden
Beyond peonies, ants contribute to the overall health of your garden ecosystem. Their tunneling activities improve soil aeration and drainage, benefiting plant roots by enhancing water and oxygen absorption. Ants also aid in seed dispersal, including native wildflower seeds, and accelerate organic material decomposition. Recognized as essential components in various ecosystems, ants are considered “keystone species” due to their vital role in supporting biodiversity. Mrgich underscores the significance of preserving ants in the ecosystem to maintain its delicate balance.
Tips
Avoid using pesticides to manage ants on peonies, as they can harm beneficial insects and disrupt the natural harmony of your garden. Instead, consider alternative strategies for ant control to prevent future pest-related issues.
How to Remove Ants Before Bringing Peonies Inside
If you wish to enjoy your peony blooms indoors without ants, follow these simple techniques for deterring ants from cut flowers:
– Tap the flower stems upside down to dislodge ants
To prevent ants on your peonies, gently tap or shake the flowers to make them drop off. Another method is to dip the blooms in a bowl of cool water for a few seconds to rinse off any remaining ants. It’s best to wait to cut the flowers until they are fully open, as ants are most attracted to unopened buds. Before bringing the peonies inside, let them sit outside in a vase of water on your porch or patio for 20-30 minutes to allow any lingering ants to wander off.
While seeing ants on your peonies may be surprising, it’s a natural part of the ecosystem. These ants actually help protect your plants from destructive pests, so it’s beneficial to have them around. Next time you notice ants on your peony buds, take a moment to appreciate the work they’re doing.
