Companion planting is a gardening technique in which different plants are grown together in order to benefit each other. By strategically pairing plants, you can maximize plant health and yield, while also reducing pests and diseases. 

In this article, we will guide you through the steps for using companion planting in your garden, including which plants work well together, and how to implement this technique in your own garden.

1. Understanding Companion Planting

  • Basil: Basil can repel mosquitoes and flies, while also attracting beneficial insects like bees and butterflies.
  • Marigolds: Marigolds can repel nematodes and other pests, while also attracting beneficial insects.
  • Nasturtiums: Nasturtiums can repel aphids and attract predatory insects like ladybugs.
  • Tomatoes and basil: Tomatoes and basil are a classic companion planting pair, with the basil repelling pests and improving the flavor of the tomatoes.
  • Corn, beans, and squash: The “Three Sisters” method involves planting corn, beans, and squash together, with the beans providing nitrogen to the soil, the corn providing support for the beans, and the squash acting as a natural mulch to retain moisture.

2. Choosing Companion Plants

  • Choose plants with similar soil and water requirements to ensure that they are both thriving in the same conditions.
  • Consider the height and growth habits of each plant to avoid shading or crowding out other plants.
  • Look for plants that have complementary pest and disease resistance to reduce the risk of infestations.
  • Choose plants that have complementary root systems, such as shallow-rooted plants planted with deep-rooted plants to avoid competition for nutrients.

3. Implementing Companion Planting in Your Garden

  • Plan your garden layout in advance, taking into account the space requirements and compatibility of each plant.
  • Plant your companion plants close together to maximize the benefits of their relationship.
  • Rotate your crops each year to avoid depleting the soil of nutrients and reducing the risk of soil-borne diseases.
  • Use natural pest control methods, such as introducing beneficial insects or using homemade sprays made from natural ingredients.
