Companion Planting Guide

I love flowers.

Peonies are my favorite, but if you were to pull up some violets from the yard and bring me a bouquet of them, we would be best friends forever.

Flowers tend to be what we think of companion planting vegetables with in our gardens.
But there is a whole world of companion plants out there, just waiting to be discovered by you!

I want to go over the basics of companion planting and why you should. The book “Carrots Love Tomatoes” by: Louise Riotte is basically the companion planting bible, if you would like an in depth resource for which plants pair well with each other.

There is an awesome chart here and you can download the PDF file.
Here is what it looks like:

The real question in all of this is: Why companion plant?

Certain plants when grown close together become other plants’ companions, and in turn create a symbiotic relationship. This could mean either one of two things.

One, the plants work together to thrive. Or two, one plant deters pests and disease from the other.

Thriving Together
Plants are like the other inhabitants of the Earth. They all compete for nutrients, water, and space. Plants that are companions tend to help each other versus choking each other out, in their search for food and room. While there are endless companions in the plant world, there are also endless enemies. What do I mean by that?
You need to carefully plan your garden out, if using companion planting techniques. Certain plants inhibit growth in others, shade each other out, or even kill other plants by producing toxins (See: The Black Walnut Tree).

Companion plants can help fertilize one another.
Beans actually fix nitrogen in the soil. If you plant them beside plants that need lots of nitrogen (Peas, Carrots, Beets, Broccoli, Kale) those varieties will take off!

The Native American “Three Sister Planting” is a great example of companion planting. “This age old grouping involves growing corn, beans and squash – often pumpkin – in the same area. As the corn stalks grow, beans naturally find support by climbing up the stalk. Beans, as all legumes, fix nitrogen in the soil, which supports the large nutritional needs of corn. Squash grows rapidly and the large squash leaves shade out weeds and serve as natural weed block. Good plant companions work in support of each other.” (Companion Planting Guide)

Pests and Diseases
Not all bugs are bad. You heard that right?
If something fly’s, craws, or wiggles around our plants we want to identify those bugs first, before taking action.
When you companion plant, you shelter beneficial bugs, drive away unwanted ones, and sometimes even confuse others so they can’t find food sources amidst your precious garden.

Instead of mass planting crops, have flowers and companion plants grouped together throughout your garden. You can companion plant flowers among your vegetables to attract those wonderful pollinators. Not to mention you can plant varieties that attract beneficial bugs that EAT the pesky ones destroying your plants!

In a garden setting we mainly hear talk about keeping bugs away, but what about keeping rodents or un-wanted mammals out of your garden?
I honestly swear by companion planting when keeping rodents out of my garden. ALL of my neighbors (except 1) have fences around their gardens or complain to me about how rabbits, squirrels, etc just eat away at their gardens.
I planted garlic around the perimeter of my garden this year. Do you know what I HAVEN’T had problems with?
Rodents. I had one broccoli plant chewed off at the beginning of the season, but after that, nothing.

Coincidence? Good Luck? God looking out for my garden?
Probably not. (Well, I know God IS looking out for my garden ha)
It’s the garlic.

I garden organically and use no pesticides (even organic ones) if possible. I believe my garden should sustain itself easily and require little help. With companion planting, it’s possible for my garden to be almost completely sustainable (in regards to pest control and pollination).

  1. Interesting post, I’ve been companion planting for a long time now and I can 100 % endorse your findings. My garden is full of pollenating insects and I had runner beans 3 weeks sooner than my neighbour even though our beans were sown at the same time.
