Growing basil in outdoor plant boxes is a fantastic way to enjoy fresh herbs right at your fingertips. However, pairing basil with the right companion plants can enhance its growth, flavor, and overall health. Here are some of the best plants to grow alongside basil in outdoor plant boxes:

1. Tomatoes: Basil and tomatoes are a classic duo. Basil improves the flavor of tomatoes and repels pests like whiteflies and mosquitoes.

2. Parsley: This herb thrives in similar conditions as basil and helps deter harmful insects while attracting beneficial ones.

3. Oregano: A hardy herb that complements basil well, oregano also acts as a natural pest repellent.

4. Marigolds: These colorful flowers repel nematodes and other pests, creating a healthier environment for basil.

5. Chives: Their strong scent deters aphids and other pests, making them excellent neighbors for basil.

When planting basil in outdoor boxes, ensure the container has good drainage and receives at least 6-8 hours of sunlight daily. Avoid overcrowding to allow proper air circulation and reduce the risk of fungal diseases.

By choosing the right companion plants, you can create a thriving basil garden that’s both productive and visually appealing. Happy gardening!
