Reduce or eradicate the need for chemical pest control completely with companion planting!
Companion Planting is an intermixing of aromatic flowers and herbs for the mutual benefit of the plant. For instance…planting Marigolds with your tomatoes will deter a number of insects & caterpillars. In addition to reducing (or replacing!) harsh pesticides by planting beneficial plants together, companion planting has been shown to create a higher crop yield.


Some plants release nutrients into the soil, which prevents the need for fertilizers the following season (For example- Legumes release nitrogen into the soil). This method of gardening is a great way to begin organic gardening!

In addition to being a benefit in growth rates and avoiding the use of chemical pesticides, companion planting also has a tendency to improve the flavor and nutrient content of the fruits and vegetables.

For example, planting sunflowers between cucumber plants not only provide the plant with beneficial shade and natural vining material, the sunflowers also absorb the chemical in cucumbers that can create a bitter flavor, resulting in considerably sweeter cucumbers.

You may have heard of “The 3 Sisters”, planting a combination of corn, pole beans and squash.

As the corn grows tall, it provides a natural trellis for the beans. Corn roots tend to grow fairly shallow, while the roots of beans tend to be much deeper, giving the corn added security and strength. The beans produce and deposit nitrogen into the soil naturally, which the corn and squash both require.

Squash naturally provide a mulch to both the beans and corn which helps them to retain moisture (and reduce the need for additional watering). In addition, the leaves of the squash are quite prickly which create a natural deterrent to many animals that might otherwise make a meal of the plants. These types of natural symbiotic relationships are the key to natural, organic gardening.

Here is a chart that shows some common items, what to plant near them (aka Good Companions) and how they help.

    • I am just starting a garden this year and this is a super list for starting out and trying to do it organically. Thank you so much for posting this here!

      also, you can add orange peel chopped up to the garden to help resist bugs.

  2. i love the chart – thank you!! i would like to be able to download it though, so i can save it or print it and take it out when i’m planting!

  3. i can attest to the efficacy of tansy. i have tansy planted next to my small garden, and i haven’t had problems with any vegetable pests this year.

    i have also heard that you can use tansy for natural dyeing. (i haven’t tried this yet, myself — but it’s on my list of things to do!)

  4. i’ve been looking for a guide like this, and i don’t want to use anything harmful because of my pets and grandson…i don’t have a “green thumb” like my mother and grandmother did, but i am determined to have live plants and not silk ones! lol.

  5. iso ~ anything non chemical that will drastically reduce the number of sow bugs aka roly-polys, pill bugs from my backyard/ summer flower garden area. i have a nice shady garden area that gets maybe 6 hrs of sun each day and these little monsters quite literally eat any soft plants that are planted. They love petunias.

    My garden is simply infested. Any turn of the dirt and you will see tons! They are so brazen they are out in force in full daylight.

    Any and all suggestions would be most appreciated.

  6. be careful planting rue next to your beans it will inhibit them. i am going to try a new idea this year. wish i could say it was mine but i read it recently.

    i am going to use a 3 ft bed and plant a single row of potatoes in the center with bush beans in a 1 ft wide band on either side of them. I’ve heard this works very well to reduce many of the pests potatoes can get and increases yields. I’ll have to let you know this fall how they did.

  7. this article and all the comments are very informative, we have been trying to get back to organic in our yard and this has helped. i book marked this page as well and will be printing the list out to refer to. anyone have any idea on keeping cardinals or blue jays out of the strawberries?

    • I would love to see it but it is completely blocked by ads… too bad

      It sounds as though your screen display resolution is off a bit, I am able to load the page without any ad issues whatsoever.
