Companion Planting

Quick definition

The practice of growing different plants together to improve growth, manage pests, support pollination, or make better use of garden space.

In plain terms

Not all plants interact with the garden in the same way. Some combinations complement each other by using space more efficiently, attracting beneficial insects, or helping create better growing conditions.

For example, tall plants can provide shade for crops that prefer cooler conditions, while flowering herbs may attract pollinators and other beneficial insects. Certain combinations can also help diversify a garden, reducing the impact of pest outbreaks.

Rather than relying on a single crop, companion planting uses plant diversity to create a healthier and more productive growing environment.

Why this matters

Companion planting helps gardeners get more from limited space while encouraging natural balance in the garden. When planned carefully, plant combinations can improve harvests, support biological control, and contribute to a more resilient garden ecosystem.

In practice

Examples

The Three Sisters method combines corn, beans, and squash in a shared planting.
Lettuce grows beneath taller crops that provide afternoon shade.
Flowering herbs attract pollinators to nearby vegetables.
Legumes contribute nitrogen to the soil before future crops are planted.

Practical applications

Mix flowers, herbs, and vegetables throughout planting areas.
Include plants that attract pollinators and beneficial insects.
Pair tall crops with plants that benefit from partial shade.
Use succession planting to maximize available space.
Combine companion planting with crop rotation for long-term soil and pest management.
