Possums are often seen as pests due to their tendency to munch on a variety of plants in gardens and yards. However, these animals are quite selective in their choice of plants, and some are reportedly unpalatable or even toxic to them. This article will explore the plants that possums generally dislike and how homeowners can use this information to their advantage.
Possums generally dislike plants with strong scents, textured foliage, or spiciness. Some of these include Cerastium tomentosum, Chaenomeles speciosa (Flowering Quince), Hibiscus syriacus, Datura Brugmansia (Angel’s Trumpets), chilli plants, marigolds, geraniums, and native plants with highly fragrant foliage like Prostanthera (native mint), Eremophilas, Myoporum, and Philothecas. However, the effectiveness of these plants in repelling possums can vary based on the local environment and climate.
Plants That Possums Dislike
A variety of plant species are known to be unattractive to possums:
- Cerastium tomentosum: An evergreen, drought-tolerant plant that possums find unpalatable.
- Chaenomeles speciosa (Flowering Quince): This deciduous shrub has a dense jumble of spiny branches and white, pink, or red flowers that deter possums.
- Hibiscus syriacus: A deciduous woody shrub with white, pink, or purple flowers.
- Datura Brugmansia (Angel’s Trumpets): This tall evergreen shrub has pendulous heavily perfumed flowers.
- Chilli plants: The spiciness of chilli plants is a deterrent for possums.
- Marigolds: The strong odor of marigolds is unpleasant to possums.
- Geraniums: These plants contain a strong-smelling substance that possums dislike.
- Native plants with highly fragrant foliage, such as Prostanthera (native mint), Eremophilas, Myoporum, and Philothecas.
These plants can be purchased from various online retailers, such as Amazon, The Sill, The Home Depot, and Etsy.
Why Possums Dislike Certain Plants
Possums are deterred by plants with strong scents or textured foliage. The strong scent of plants like rosemary or garlic is unappealing to possums. Similarly, plants with prickly, hairy, or sticky foliage, such as some types of Acacias, Chrysocephalum, and some tea tree varieties, are less likely to be eaten by possums.
Using Plants to Deter Possums
To use these plants effectively to deter possums from your garden or yard, you can follow these strategies:
- Plant possum-attracting plants like eucalyptus at the edge of your garden to keep them occupied and away from your other plants.
- Use scent-based deterrents. Some effective smells that possums hate include mothballs, camphor, garlic, onion, and animal-derived fertilizers.
- Erect physical barriers around your garden to prevent possums from accessing your plants. This can include netting systems, fences, or tree guards.
- Maintain a clean garden to make it less attractive to possums.
- Eliminate food sources like pet food left outside overnight, unsecured garbage cans, fallen fruits and vegetables, and seeds under bird feeders.
- Trim bushes and keep your yard free of debris to reduce hiding spots for possums.
Remember that these strategies may require constant reapplication or maintenance to remain effective in the long term.
The Impact of Climate or Region
The climate or region can indeed affect a possum’s aversion to certain plants, as their dietary preferences and tolerances are influenced by the local environment and the availability of specific plant species.
While plants alone may not be very effective in repelling possums, a combination of different pest control methods, including repellent sprays, predator urine, and motion-activated devices, may provide better results in deterring possums from your garden. Remember, each plant has unique requirements, so it’s essential to research the specific needs of the plants you purchase to ensure their success in your space.
