Creating a mouse-resistant outdoor plant box requires selecting plants that naturally deter rodents while thriving in your garden. Here are some of the best options:

1. Lavender – Its strong fragrance repels mice and other pests, making it a beautiful and functional choice.

2. Mint – The potent scent of mint is highly effective at keeping rodents away, but it’s best grown in containers to prevent spreading.

3. Rosemary – This aromatic herb is unappealing to mice and adds flavor to your cooking.

4. Marigolds – Their bright flowers emit a scent that deters rodents while attracting beneficial insects.

5. Daffodils – These contain toxic compounds that mice avoid, making them a safe and colorful addition.

For best results, combine these plants with proper garden maintenance, such as removing debris and securing compost bins, to further discourage rodent activity. By choosing the right plants, you can enjoy a lush, mouse-free outdoor space.
