Companion Gardening: A Guide to Planning and Planting for a Bountiful Harvest

Understanding Companion Planting

Companion planting is a gardening technique that involves growing different plant species together for their mutual benefit. While not always based on scientific evidence, it draws upon traditional gardening knowledge and observations. By understanding garden biodiversity and the interactions between plants, you can make informed choices to enhance the health and productivity of your garden.

Benefits of Companion Planting

Increased fruit production: Certain companion plants can stimulate growth and improve fruit set.
Pest deterrence: Some plants release scents or compounds that repel insects and other pests.
Soil health improvement: Leguminous plants, such as beans and peas, fix nitrogen in the soil, making it available to other plants.

Classic Example: The Three Sisters

The “three sisters” planting method is a classic example of companion planting. Corn, beans, and squash are grown together in a mutually beneficial arrangement:

Corn provides support for climbing beans.
Beans add nitrogen to the soil, stabilizing corn during high winds.
Large squash leaves shade the ground, retaining moisture and suppressing weeds.
