Companion planting is the practice of growing certain plants together in order to improve one another’s growth. By having some plants close to each other, they can help negate issues that come with growing them on their own.
For example, if you’re growing tomatoes, they are often impacted by aphids. Marigolds are great at attracting aphids to them. By growing a plant like marigolds near your tomatoes, you can save the tomatoes from getting the brunt of the issue.
Companion plants are a pretty important consideration to make when planning a vegetable garden. Not only do they help to optimize the growing conditions for your desired plants, but they can also help to ward off pests and diseases.
