Companion planting is a gardening technique that uses the mutual benefits of different plants to support each other’s growth.
What’s fascinating is that each plant has its own unique set of characteristics that can either promote or inhibit the growth of other nearby plants.
This gardening method is widely popular because it can enhance soil health, maximize space, and reduce pest and disease problems.
In this article, we’ll explore the essential aspects of companion planting to help you improve your food garden’s yields.
UNDERSTANDING COMPANION PLANTING
Companion planting is a way of harnessing the synergies between plants to maximize growth potential.
REPELLING AND ATTRACTING INSECTS
Some plants produce natural chemicals that can deter pests or attract beneficial insects to the garden.
For instance, planting marigolds alongside tomato plants can deter whiteflies and nematodes.
Similarly, planting herbs like dill and fennel can attract ladybugs which are natural predators of aphids and mites.
SOIL ENRICHMENT
Planting certain crops alongside others can help to improve the overall soil quality.
Legumes like beans and peas, for example, can fix nitrogen from the atmosphere and add it to the soil, benefiting plants that require nitrogen to grow.
CHOOSING COMPANION PLANTS
Choosing companion plants is all about identifying plants that will complement each other’s growth and offer mutual benefits.
Some examples of commonly paired plants include
- Tomatoes and Basil – Basil can repel pests that commonly attack tomato plants while improving their flavor.
- Pumpkins and Corn – Planting corn as support will enable pumpkin vines to grow upward instead of sprawling on the ground.
AVOIDING NEGATIVE COMPANION PLANTS
While it’s essential to complement plants, certain plants can be detrimental when planted together.
For instance, planting okra and pole beans next to each other can lead to stunted growth.
Similarly, planting onions and beans close together can result in the stunted growth of both plants.
PLANTING STRATEGIES FOR SUCCESSFUL COMPANION PLANTING
In companion planting, there are several strategies you can use to enhance the plants’ benefits.
THREE SISTERS METHOD
This method involves planting corn, beans, and squash together. Corn provides a trellis for the beans while the beans fix nitrogen and release it to the soil, and the squash acts as a natural mulch by shading the soil and inhibiting weed growth.
INTERCROPPING
This method involves planting crops in alternating rows or blocks to maximize space and yields.
SUCCESSION PLANTING
This strategy involves planting successive crops in the same spot to extend the harvest season and reduce pests and disease problems.
