Do Marigolds Really Control Pests in a Garden?
Marigolds have long been touted as a natural pest control method in gardens. They are said to repel a variety of pests, including aphids, thrips, and whiteflies. But do marigolds really work?
The Research
There is some scientific evidence to support the claim that marigolds can deter pests. One study found that aphids were 80% less likely to infest plants that were surrounded by marigolds. Another study showed that whiteflies were 72% less likely to lay eggs on plants that were treated with marigold extract.
How Do Marigolds Work?
Marigolds produce a compound called pyrethrum, which is a natural insecticide. Pyrethrum works by disrupting the nervous system of insects. This causes them to become disoriented and unable to feed or reproduce.
Benefits of Using Marigolds
In addition to repelling pests, marigolds also have a number of other benefits. They are easy to grow, they attract pollinators, and they can help to improve the soil health.
How to Use Marigolds for Pest Control
To use marigolds for pest control, simply plant them around the perimeter of your garden or near the plants that you want to protect. You can also sprinkle dried marigold flowers around your plants.
Conclusion
