5 Time Tested Benefits of Companion Planting

Benefits of Companion Planting

Companion planting has been used by gardeners throughout history as a way to maximize the results they get from their vegetable gardens. Companion planting is the idea of planting certain vegetables, herbs and flowers close together. The closeness or proximity of the plants leads to them “helping” each other. The plants “help” each other by drawing in insects, deterring pests, even providing shade and nutrients for each other.

1 – Companion plants maximize space

Many times when people think of a garden they thing of long rows of single plants. Companion planting allows you to plant in layers and maximize the space you have available. This method allows for more plants and more variety in a much smaller space. Plants that have shallow root systems can be planted next to plants with deeper root systems. An example of this would be tomatoes planted next to carrots or onions.

2 – Companion plants help each other grow

There are several examples of how companion plants help each other grow. Plants with large stalks like corn or sunflowers provide the perfect trellis for beans or snap peas. Squash, cucumbers or pumpkins that grow on the ground as spreading vines can provide shade for taller plants. These plants keep the soil cool and prevent weeds. In our garden. in our garden this year we have planted lettuce under taller plants like tomatoes. The tomatoes should provide some shade for the lettuce in the Texas sun.

3 – Companion plants share nutrients

Companion plants also help each other by bringing nutrients to each other. Beans or legumes add nitrogen to the soil which feeds the other plants around them.

4 – Companion plants attract pollinators

Using marigolds or other flowers with bright colors assist your plants in drawing in bees to pollinate those flowers giving you the start of your vegetables. We planted marigolds in each of our beds to assist in drawing in bees. We were in Sonoma last year for a half marathon and went to the Sunset Test Garden. They had a beautiful display with grape tomatoes over steel trellises with lavender at the bottom to attract bees. I’ve planted lavender in each of my beds to try and replicate this.

5 – Companion plants deter insects

Companion planting wisdom advises that you should not plant large groups of like plants together as pests are attracted to large groupings. Think of the traditional rows of crops or bunches of plants. The garden pest or insects see’s this grouping of plants as a buffet. The idea is that if you mix your vegetable plants in with herbs and flowers many insects or pests become confused. Mixing up your plants with different colors and scents removes the “Eat at Joe’s” sign from your garden.

Bringing it all Together – A Companion Planting Story

The simplest explanation or example of how plants can help each other through companion planting is referred to as “The Three Sisters”. This method was used by Native American’s for centuries. This method was focused on plating corn, beans and squash together. According to legend, these three plants were gifts from the Gods and were meant to be grown, eaten and celebrated together.

  1. The corn was the older sister and provided support for the beans to climb and grow
  2. The bean plant was the giving sister. The beans pull nitrogen from the air and share that nitrogen with corn and the squash
  3. As the beans grow up the corn stalk they hold each of the plants together, essentially holding the family together
  4. The large leaves of the squash shade the soil and the roots of all the plants preventing weeds and keeping the roots cool
  5. The prickly leaves of the squash keep animals away from all of the plants

  1. Julie I enjoyed rdg this wonderful info on companion gardening. Something I’ve learned about is KEYHOLE gardening. The original idea came from Africa. It uses very little water, the fertilizer is one part brown (like cardboard, newspapers, old telephones books) to 3 parts green ( leaves, grass cuttings, vines , anything green) . the garden is in shape of a keyhole and averages 3-4 ft high, about 6 ft wide. I have a DVD I can loan to you. The layers of brown and green slowly decompose and feed /water the plants. They are easy to maintain and one successful family of 10 has veggies growing year round. Internet can show you lots of ideas. I want to start one. I’ve enjoyed reading your blog.
