Can Marigolds Keep Deer Away? Here's What You Need to Know

Table of Contents

Deer can be a major nuisance for gardeners, wreaking havoc on flowers and other plants. While there are many chemical sprays and fencing options available to keep deer out of your garden, some people prefer natural methods. One option that has gained popularity in recent years is using Marigolds as a deer-repelling plant.

How do Marigolds Keep Deer Away?

The Smell of Marigolds Deter Deer

Marigolds have a strong scent that can repel deer. The smell is so strong that it can mask the scents of other plants that deer may find attractive. There are several compounds found in marigolds that are responsible for their strong odor, including thiophenes, which have been found to be an effective mosquito repellent.

Marigolds Affect the Senses of Deer

Marigolds produce chemicals that are unpleasant to deer, causing them to recoil from the area around the plant. Scientists believe that the production of these chemicals is an adaptation to protect the plant from herbivores.

Marigolds Mask the Smell of Other Plants From Deer

Marigolds release chemicals into the air that can interfere with a deer's sense of smell. This masking effect makes it difficult for deer to detect the scents of other plants that they would otherwise find palatable.

The Resilience of Marigolds

Another reason why marigolds can be an effective deterrent against deer is their resilience. Marigolds are easy to grow and can withstand harsh weather conditions, making them an ideal choice for gardeners who want a low-maintenance solution for keeping deer away.

While there is no guarantee that marigolds will keep all deer away, they are certainly worth trying if you're looking for a natural solution. The colorful flowers look great in any garden, and they may just save your other plants from being eaten by deer.
