Companion Planting

Companion Planting Understanding how plants interact is crucial to successfully growing multiple crop varieties and for successful farming and gardening in general.

The Importance of Understanding Plant Interactions Successful farmers and growers are well aware of their nutrient demands their crops place upon their soil or aquaponic/hydroponic systems. They know that some plants in particular, like legumes, fix nitrogen and add to soil nutrition while others demand a great deal from the soil or nutrient solution without giving much back throughout their life cycles. Some plants even produce various chemicals that can affect the growth of other plants around them. Each of these factors play a large role in determining how well plants grow together. While some plants can inhibit the growth of others, helping to produce maximum yields, surpress pests and facilitate better pollination, pairing the wrong types of plants together can lead to poor or stunted growth and a frustrated farmer/grower. “Companion Planting� involves planting different plants near each other for overall greater production.

A Brief History of Companion Planting While Companion Planting has been prominent throughout the world anywhere polyculture (growing multiple varieties of crops in the same space), it is most famously used by indigenous populations throughout North America.


(Source: http://www.threes.com/cms/images/stories/food/3sisters.jpg) Using a natural trellis Companion Planting technique, Native peoples used the corn’s stalk to provide a trellis for pole beans to climb, while also fixing nitrogen and subsequently provide essential soil nutrition for the corn. This technique allowed for increased yields for both beans and corn. This practice has been widely adopted over the years by organic gardeners and permaculture practitioners believing growing different plant species together helps them all thrive. Techniques like the “Three Sisters” incorporate squash into corn and bean production in order to create a trifecta of plant triumph. While the corn provides a natural trellis for the beans to climb (getting rid of the need for poles), and the beans continue to fix nitrogen to promote overall soil health and production power, the squash spread themselves horizontally and help block sunlight/weed establishment.
