The Science and Art of Companion Planting
Companion planting is a gardening technique that involves growing different plants in close proximity for mutual benefit. These benefits can include pest control, attracting beneficial insects, enhancing plant growth, and improving flavor. While some pairings are backed by scientific research, many are based on anecdotal evidence passed down through generations of gardeners.
How Does it Work?
- Pest Deterrence: Some plants emit odors that repel harmful insects (e.g., marigolds deter nematodes).
- Attracting Beneficials: Certain flowers or herbs attract predatory insects that feed on pests (e.g., dill attracts ladybugs).
- Nutrient Cycling: Legumes (like beans and peas) fix nitrogen in the soil, benefiting nitrogen-hungry plants like corn.
- Shade and Support: Tall plants can provide shade for sun-sensitive plants, or a natural trellis for climbing vines.
- Soil Improvement: Plants with deep taproots can break up compacted soil, making it easier for other plants to grow.
Popular Companion Planting Combinations:
| Main Plant | Good Companion(s) | Benefit |
|---|---|---|
| Tomatoes | Basil, Marigolds | Improved flavor, pest deterrence |
| Corn | Beans, Squash | Nutrient cycling, physical support, shade |
| Roses | Garlic, Chives | Aphid deterrence, disease prevention |
| Carrots | Rosemary, Lettuce | Deters carrot rust fly, keeps soil cool |
| Cabbage | Dill, Mint | Deters cabbage worms |
