1. What tradition… and permaculture say

In folk knowledge as well as in the principles of permaculture, the association of basil and tomato is recommended for several reasons:

• 🌿 Repellent effect: Basil emits essential oils that would repel aphids, whiteflies, thrips…

• 🍅 Taste improvement: It is often said that tomatoes grown near basil are more flavorful.

• ☀️ Climate compatibility: Both plants like sunlight, warmth, and moderate watering.

📌 Note: while the effects on flavor are not scientifically proven, the combination is mainly effective for creating an ecological balance in the garden.

2. The true strengths of the tomato + basil duo

🌿 A natural protection

• Basil masks the smell of tomatoes, making it harder for pests to locate them.

• Its volatile oils act as a natural repellent.

• When it flowers, basil attracts bees, hoverflies, and other useful helpers.

🪴 Great compatibility

• Similar needs: warmth, rich soil, watering at the base.

• Their growth cycle is synchronized, from spring to summer.

• Basil remains compact and does not shade the tomatoes.

👃 A better taste?

There is no conclusive scientific study on the direct influence of basil on the flavor of tomatoes. But many gardeners are convinced: tomatoes grown this way would be more aromatic, perhaps thanks to generally optimized growing conditions.
