I remember listening to my grandfather when I was growing up talking about how you have to grow basil next to tomatoes.  

I never quite understood what he meant by that except that maybe they taste good together so grow lots of each.

Of course, there was no companion planting chart back then.

It wasn't until I planted my first tomato plant and experienced the pain and frustration that comes along with all those pests gobbling up those majestic globes of juiciness.

There had to be a way to prevent this without spraying them with chemicals (before there was really an organic movement). 

There wasn't much guidance readily available in the internet's infancy.

Fast forward to much later in my gardening hobby where there is an abundance of gardening information. 

My curiosity later returned after reading about the Three sister's planting.

Three Sister's Planting | Companion Planting Roots

Native Americans naturally interplanted their crops to help sustain them both physically and spiritually. 

The most commonly known practice is called the three sister planting: Corn, Beans & Squash.

This trio of plants helped each other to sustain themselves naturally.  

The beans provide the soil with much nitrogen.  

The corn acted as trellises for the beans and provided shade for the squash.  

The squash covered the soil to help prevent water evaporation.

A perfect harmony of plants.  These practices later led to other interplanting techniques that have been refined over the years such as crop rotation.

The companion planting chart below has many of these examples.

What is Companion Planting?

Companion planting is the act of interplanting plants that can mutually benefit each other.  This could mean that they help each other by soil nutrition, physical, or other pest reduction means.

Pest management has become a bigger issue in today's commercial farming practices.  However, companion planting on a smaller scale has been met with much success.

Here are a few methods of companion planting:

  • Trap Cropping: involves planting another plant to attract pests away from your desired crop.  Radishes are one example that attracts flea beetles and root flies away from cabbages or broccoli.
  • Repellant Intercrops: Interplanting certain plants in between and around your other crops.  My favorite repellant is onions.  We use it as a border around our gardens.  My neighbor always wondered why his garden got snacked on and mine didn't.
  • Row Cropping: Planting alternate rows of crops that benefit each other.  Tomatoes and basil always seem to end up as neighbors in our garden.

Reasons for Companion Planting

companion planting guide 02

In today's world, we are constantly bombarded with pollutants and chemicals. 

The air we breathe, the food we consume, and increasing UV radiation from the sun.

Its no wonder why it is important to reduce this over the course of a lifetime if we can.

I'll give just about any safe method a try if it helps me and the environment in any way.  

Chemical reduction is just one of the many reasons.

Here are few more to help you give it a try:

  • Fewer Chemicals: Natural means to help repel insects
  • Attract beneficial bugs: Some bugs are drawn towards plants and can naturally fend off unwanted pests.
  • Shade protection: Provide necessary shade for some crops during the dog days of summer
  • Water retention: Closely planting some crops can help to cover up otherwise bare soil to further reduce evaporation

Are you convinced yet on giving this technique a try?  There are so many benefits for companion planting.

Following the methods of companion planting is a natural way to mimic the rhythm of the existing ecosystems.  Nature always seems to be paired with these examples.

Books about Companion Planting

Sometimes you need a good reference to hold in your hand.  There is so much more to learn on this topic that it is difficult to summarize in a 1500 word blog post.

You need some good references to help shine more knowledge on the subject.  There are 2 fantastic reference books that really shine a light on the subject.

Both of these authors are experts & champions of companion planting.

The first book is Carrots Love Tomatoes by Louise Riotte.  You can find it here at Amazon.

She definitely gets credit with solidifying the knowledge that I have picked up with these methods.  Her book highlights each plant and the best choices for interplanting.

Vegetables are not the only plants she discusses.  She goes into depths with some trees, bushes and other gardening tips.

The second book is Rodale's Ultimate Encyclopedia of Organic Gardening that you can find here at Amazon.

This is a well-versed guide that does go over quite a bit of interplanting and companion planting guidelines for vegetables and flowers.

My copy has a vast amount of dirt all over it because I bring it into the garden with me as a reference sometimes.

These 2 books are a great start in the world of companion planting.
