How Marigolds Repel Pests

Marigolds release a strong scent that confuses pests and keeps them away. They also contain compounds that repel harmful insects, such as:

• Limonene: Deters whiteflies and aphids.
• Alpha-terthienyl: Toxic to root-knot nematodes.
• Pungent Scent: Helps mask the smell of vegetable plants, reducing bug infestations.

Best Types of Marigolds for Pest Control

Different marigold varieties offer varying levels of protection:

• French Marigolds: Effective against root-knot nematodes and whiteflies.
• African Marigolds: Best for repelling Japanese beetles and squash bugs.
• Mexican Marigolds: Excellent for deterring harmful insects while attracting pollinators.

How to Use Marigolds in Your Garden

To maximize their pest-repelling abilities, follow these steps:

1. Plant marigolds around vegetable plants like tomatoes and beans.
2. Use companion planting to create a pest barrier.
3. Intercrop marigolds with squash and cucumbers to deter squash bugs and cucumber beetles.
4. Avoid overcrowding to prevent powdery mildew.
