Sweet potatoes are a versatile and nutritious crop that can be grown in a variety of climates. They are also great for companion planting, which is the practice of planting different crops together to improve their growth and yield while also reducing pest and disease problems.

What is Companion Planting?

Companion planting is the practice of planting different crops together to achieve specific benefits. The idea is that some plants have natural properties that can help other plants grow better, while also reducing the risk of pests and diseases. Some plants also attract beneficial insects that can help pollinate other plants and control pests.

Companion planting has been used for centuries by farmers and gardeners around the world. In addition to improving plant health and productivity, it can also help to conserve water, reduce soil erosion, and create a more diverse and sustainable ecosystem.
