Marigold Pest Control
Marigolds contain chemical compounds like alpha-terthienyl and pyrethrum, renowned for their insect-repelling properties. These compounds disrupt the life cycles of many insects, making marigolds an excellent natural pest deterrent.
The aroma of marigolds can deter certain pests from invading your garden. Additionally, their roots release toxic chemicals that are particularly effective against nematodes and other soil-dwelling pests, providing below-ground protection.
