Gardening is more than planting seeds and watching them grow. It’s also about creating a healthy environment for plants to thrive. One way gardeners do this is by using different types of crops that support the garden in unique ways. These are called companion crops, trap crops and cover crops. Each plays a special role in improving soil health, managing pests and boosting overall garden productivity.
Companion crops: Working together
Companion crops are plants grown close together because they help each other. Some companions improve growth, while others protect against pests or diseases. For example, planting basil near tomatoes can improve tomato flavor and help repel insects. Marigolds are often planted with vegetables because they deter nematodes and aphids.
Companion planting works by:
- Attracting beneficial insects like ladybugs and bees
- Repelling harmful pests
- Improving soil nutrients (some plants fix nitrogen)
- Providing shade or support for other plants
This method is especially useful in small gardens where space is limited. By choosing the right companions, gardeners can reduce the need for chemicals and create a more balanced ecosystem. For more information, check out this article by the University of Minnesota.
