Terms of the Trade: What Are Companion Plants?
Companion plants are plants that grow better when planted together. Putting these plants next to each other can chase away pests and help the plants grow, as well as help you utilize your garden space better since some plants can provide shade for others. There are also options where one plant grows up and the plant next to it grows down. Lettuce, for example, can be planted next to a variety of other plants including carrots. Carrots grow deep in the soil while lettuce grows closer to the surface. Lettuce also grows faster. Swiss chard is often used in companion planting because it is a good source of vitamins and withstands high temperatures. The plant also attracts beneficial insects.
