Companion Planting: The Benefits of Growing Plants Together in Your Garden

companion planting benefits

Do you want to improve the health and productivity of your garden? Companion planting may be the answer you’ve been looking for. This technique involves planting different crops together in a way that benefits each other. By combining plants with complementary characteristics, you can create a symbiotic relationship that helps to control pests, improve soil quality, and increase yields.

Benefits of Companion Planting

Natural Pest Control

One of the most significant benefits of companion planting is that it can help control pests naturally. By planting certain crops together, you can create a natural barrier that repels pests or attracts beneficial insects that prey on pests. For example, planting marigolds with tomatoes can help repel nematodes, while planting basil with tomatoes can attract beneficial insects that prey on tomato hornworms.

Improved Soil Health

Companion planting can also help improve soil health. Some plants, such as legumes, have the ability to fix nitrogen in the soil, which can benefit other plants in the same bed. Additionally, planting a variety of crops together can help prevent soil depletion and erosion, as each plant has unique nutrient requirements.

Increased Crop Yield

Another benefit of companion planting is that it can increase crop yield. Certain plants, such as beans and peas, have the ability to climb and provide shade for other plants, which can help keep the soil moist and cool. Additionally, planting crops together that have different root depths can help prevent competition for nutrients, leading to healthier plants and higher yields.


Companion planting can also help promote biodiversity in the garden. By planting a variety of crops together, you can create a diverse ecosystem that attracts a variety of beneficial insects and wildlife. This can help create a more sustainable garden that requires less maintenance and is more resilient to pests and disease.

Types of Companion Planting

1. Pest Repellent Companion Planting

One of the most common types of companion planting is pest repellent. This involves planting certain plants that naturally repel pests near crops that are susceptible to insect damage. For example, planting marigolds near your tomato plants can help keep pests like aphids and whiteflies away.

2. Nutrient Accumulator Companion Planting

Another type of companion planting is nutrient accumulator. This involves planting certain plants that have deep roots and can accumulate nutrients from the soil. These plants can then be cut down and used as mulch or compost to enrich the soil for other crops. Examples of nutrient accumulator plants include comfrey and clover.

3. Nitrogen-Fixing Companion Planting

Nitrogen is an essential nutrient for plant growth, and some plants have the ability to fix nitrogen in the soil. This means they convert atmospheric nitrogen into a form that plants can use. By planting nitrogen-fixing plants like beans and peas near other crops, you can help enrich the soil with this important nutrient.

4. Shade-Tolerant Companion Planting

Finally, shade-tolerant companion planting involves planting crops that can thrive in the shade of taller plants. For example, planting lettuce or spinach near taller plants like tomatoes or corn can help protect them from the sun and keep them cooler during hot weather.

How to Plan a Companion Planting Garden

When planning a companion planting garden, there are a few things you should consider to ensure a successful and thriving garden.

First, consider the plants you want to grow and their individual needs, such as light, soil, and water requirements. You should group plants with similar needs together, so they can share resources and thrive together.

Next, research plant pairings that have been known to work well together. For example, planting basil with tomatoes can improve the flavor and repel pests.

You should also consider the timing of planting. Some plants may need to be planted earlier or later than others, so they can grow and mature at the same time.

When deciding where to plant, make sure to leave enough space between plants to allow for proper growth and airflow. This will help prevent diseases and pests from spreading.

Consider using raised beds or containers for your companion planting garden. This can help with drainage and soil quality, and make it easier to control the growing environment.

Finally, make sure to rotate your crops each season to prevent soil depletion and disease buildup. This means planting different plants in different areas each year.

Common Companion Planting Combinations

When it comes to companion planting, there are several tried-and-true combinations that many gardeners swear by. Here are some of the most common companion planting combinations:

  • Tomatoes and Basil: Planting basil alongside tomatoes can help to improve the flavor of the tomatoes and repel pests like whiteflies and aphids.
  • Corn, Beans, and Squash: Known as the “Three Sisters,” planting corn, beans, and squash together can create a mutually beneficial ecosystem. The corn provides a structure for the beans to climb, while the beans fix nitrogen in the soil, which benefits the corn and squash. The squash, in turn, provides ground cover to help retain moisture and suppress weeds.
  • Carrots and Onions: Planting onions near carrots can help to repel carrot flies, while carrots can help to repel onion flies.
  • Cucumbers and Radishes: Planting radishes near cucumbers can help to deter cucumber beetles and squash bugs.
  • Lettuce and Chives: Planting chives near lettuce can help to repel aphids and slugs.

Keep in mind that these are just a few examples of companion planting combinations, and there are many other combinations that can work well in your garden. Experimenting with different combinations can be a fun and rewarding way to improve the health and productivity of your garden.


In conclusion, companion planting is a great way to improve the health and productivity of your garden. By planting certain plants together, you can create a mutually beneficial environment that helps to deter pests, improve soil quality, and increase yields.

If you want to have a successful and healthy garden, you should definitely consider incorporating companion planting into your gardening practices. With a little bit of planning and research, you can create a thriving garden that is both beautiful and productive.
