Companion Planting Guide Chart: The Ultimate Guide

Table of Contents

When it comes to gardening, there are many factors to consider, such as soil quality, sunlight, and water. One factor that is often overlooked is companion planting. Companion planting is when two or more plants are grown together because they benefit each other in some way. For example, one plant might repel pests that would harm the other plant, or one plant might provide shade for the other. In this article, we'll be discussing everything you need to know about companion planting, including how to use a companion planting guide chart.

What is a Companion Planting Guide Chart?

A companion planting guide chart is a tool that helps gardeners determine which plants grow well together and which ones do not. It usually shows a list of different vegetables, fruits, and herbs and indicates which ones should be planted together and which ones should be kept apart. The chart takes into account factors such as soil pH, nutrient requirements, and pest resistance.

How to Use a Companion Planting Guide Chart

Using a companion planting guide chart is simple. First, choose the plants you want to grow. Then, find those plants on the chart and look for other plants that are recommended to be grown alongside them. You can also use the chart to identify plants that should be avoided if you're growing certain types of plants.

Example of a Companion Planting Guide Chart

The Benefits of Companion Planting

There are many benefits to companion planting. First and foremost, it can help improve the health of your plants. When plants are grown together in a beneficial way, they can help each other fight off pests and diseases. Companion planting can also help to improve soil quality by promoting the growth of beneficial microorganisms.

Other Benefits of Companion Planting

Companion planting can also help to increase crop yields. Some plants, when grown together, can actually help to improve each other's growth rates. Additionally, companion planting can help to conserve water since the roots of some plants can help to retain moisture in the soil.

Example: Three Sisters Companion Planting

One example of successful companion planting is the "Three Sisters" method used by Native American tribes. In this method, corn, beans, and squash are planted together. The corn provides a support structure for the beans to grow on, while the beans help to fix nitrogen in the soil, which benefits both the corn and the squash. The squash, in turn, helps to shade the soil and retain moisture.

Common Companion Planting Combinations

There are many different combinations of plants that work well together in a companion planting garden. Here are some common combinations to consider:

Tomatoes and Basil

Tomatoes and basil are a classic combination in the garden. Basil can help to repel pests that would harm the tomatoes, and it also helps to improve the flavor of the fruit.

Example: How to Plant Tomatoes and Basil Together

To plant tomatoes and basil together, simply place a few basil plants around the base of each tomato plant. Be sure to space them out so they don't overcrowd each other.

Carrots and Onions

Carrots and onions are another great combination. Onions can help to repel pests that would harm the carrots, and they also help to improve the flavor of the root vegetable.

Example: How to Plant Carrots and Onions Together

To plant carrots and onions together, simply scatter onion sets throughout the carrot bed when you're planting your seeds.

Peppers and Cilantro

Peppers and cilantro are a great combination for Mexican cuisine. Cilantro can help to repel harmful insects from the pepper plant, and it also complements the flavor of the fruit.

Example: How to Plant Peppers and Cilantro Together

To plant peppers and cilantro together, simply scatter cilantro seeds around the base of each pepper plant.

Mistakes to Avoid When Companion Planting

Although companion planting can be very beneficial to your garden, there are some common mistakes to avoid.

Planting Incompatible Plants Together

One of the biggest mistakes people make when companion planting is planting incompatible plants together. Be sure to check your companion planting guide chart before planting anything together.

Example: Incompatible Companion Plants

Some examples of incompatible plants include tomatoes and corn, which both require a lot of nutrients and can compete with each other for them. Additionally, potatoes and tomatoes should not be planted together because they are both susceptible to the same diseases.

Planting Too Close Together

Another mistake people make is planting their companion plants too close together. Be sure to follow the spacing recommendations on your seed packets or in your gardening book.

Example: Overcrowded Companion Plants

Overcrowding your plants can lead to competition for resources and can also create an environment that is conducive to pests and disease.


Companion planting is a great way to improve the health and yield of your garden. By using a companion planting guide chart, you can choose the best combinations of plants to grow together. Remember to avoid common mistakes like planting incompatible plants together and overcrowding your plants.
