Keep reading to learn more about why cosmos are deer resistant, and how to minimize the chances of deer browsing on your plants.
Why Are Cosmos Deer Resistant?
Cosmos are generally considered deer resistant because they produce an aromatic scent that deer find unpleasant. The aromatic oils released by the foliage of the cosmos plant are thought to act as a deterrent to deer browsing. Additionally, the foliage of the cosmos plant is usually too tough and fibrous for deer to chew.
In addition to their scent and texture, the size of the cosmos plant may also be a deterrent to deer. Cosmos can grow to be quite tall, often reaching heights of 2-5 feet. Since deer prefer to browse on plants that are close to the ground, they may be less likely to browse on taller plants like cosmos.
How to Keep Deer Away From Your Cosmos
Although cosmos are generally considered deer resistant, there are certain conditions in which deer may still be tempted to browse on them. Here are a few tips and ideas to help keep deer away from your cosmos:
Install a deer fence around your garden. Deer fences are an effective way to keep deer out of your garden and protect your plants from browsing.
Spray a commercially available deer repellent on your plants. Repellents can help to deter deer from browsing on your plants.
Plant deer-resistant companion plants. Planting companion plants that are less attractive to deer can help to draw their attention away from your cosmos.
Avoid using chemical fertilizers or pesticides. Deer are attracted to the smell of these chemicals, so using them in your garden can actually encourage deer to browse on your plants.
Remove debris from the garden. Removing fallen leaves, twigs, and other debris from your garden can help to discourage deer from browsing on your plants.
By following these simple tips and ideas, you can help to ensure that your cosmos remain deer resistant. Additionally, it’s important to remember that deer browse on plants when they are desperate for food. If there are no other food sources available, deer may be tempted to browse on your plants.
