Benefits of Companion Planting
Companion planting is a gardening technique that involves growing different plants together, taking advantage of the positive relationships they can form. By incorporating companion planting in your urban garden, you can enjoy a multitude of benefits.
Increasing biodiversity
One of the major benefits of companion planting is the increase in biodiversity it brings to your garden. By growing a variety of plant species, you invite a wide range of organisms, such as insects and beneficial microorganisms, to thrive in your garden. This biodiversity not only enhances the overall health of your garden ecosystem but also helps maintain a balanced and sustainable environment.
Natural pest control
Companion planting can also serve as a natural pest control strategy. Some plants naturally repel pests, while others attract predatory insects that feed on pests. By strategically choosing companion plants that repel or attract certain insects, you can effectively control pests in your garden without relying on harmful chemicals.
Improving soil fertility
Certain plant combinations can enhance soil fertility by utilizing different nutrients and preventing nutrient depletion. For example, legumes, such as peas and beans, have the ability to fix nitrogen from the air, which benefits neighboring plants that require nitrogen for growth. Additionally, some plants have deep roots that help break up compacted soil, improving overall soil structure and nutrient uptake.
Choosing Complementary Plants
To make the most out of companion planting, it is important to understand the relationships between different plant species. Here are some key factors to consider when choosing complementary plants for your garden.
Understanding plant relationships
Different plants have different needs and abilities, and understanding their relationships can help you create harmonious planting combinations. Some plants release natural compounds that can inhibit the growth of certain pests or diseases, while others attract beneficial insects that provide pollination or pest control services. By studying plant relationships, you can make informed decisions about which plants to grow together.
Identifying beneficial companions
Certain plants have natural affinities for one another and thrive when grown together. For example, tomatoes and basil are often touted as excellent companion plants because basil is believed to improve the flavor of tomatoes while repelling pests that commonly affect tomato plants. Similarly, carrots and onions are known to benefit from being grown together, as onions can deter carrot fly.
Avoiding harmful combinations
Just as some plants benefit from being grown together, others should be kept apart. Some plants emit chemicals that can hinder the growth of nearby plants, a phenomenon known as allelopathy. For example, planting beans and onions together can inhibit the growth of both plants. It is important to research potential harmful combinations and avoid planting them in close proximity.
Creating a Planting Plan
When incorporating companion planting in your garden, it is essential to develop a well-thought-out planting plan. Here are some strategies to consider when creating your plan.

Carrots and onions make excellent companions in the garden. Onions act as a natural deterrent for carrot fly, which can damage carrot crops. Interplanting onions between rows of carrots can help protect your crop from this common pest while utilizing space efficiently.
Lettuce and radishes
Lettuce and radishes are another great combination. Radishes have a quick growing cycle and can be harvested before lettuce reaches its full size. By planting radishes alongside lettuce, you can make the most of your garden space and enjoy a variety of fresh greens.
Companion Planting Techniques
To effectively incorporate companion planting in your garden, it is important to familiarize yourself with different techniques. Here are three popular companion planting techniques to consider.
Interplanting
Interplanting involves growing different plant species together in the same area, maximizing space utilization. For example, you can plant lettuce between rows of broccoli or radishes between rows of carrots. Interplanting also helps diversify the garden ecosystem and promote overall plant health.
Bordering and edging
Creating borders or edges using specific companion plants can help deter pests and attract beneficial insects. For instance, planting marigolds around the perimeter of your garden can help repel harmful insects like nematodes while attracting pollinators. Experiment with different bordering and edging plants to find the combinations that work best for your garden.
Trap cropping
Trap cropping involves planting a sacrificial plant to attract pests away from your desired crops. For example, planting marigolds near a crop that is prone to aphid infestation can divert the aphids to the marigolds, preserving the health of your main crop. Trap cropping can be an effective strategy to minimize pest damage in your garden.
Attracting Beneficial Insects
Beneficial insects play a vital role in any garden ecosystem. By attracting these insects to your urban garden, you can promote pollination, pest control, and overall balance. Here are some ways to attract beneficial insects through companion planting.
Flowering plants for pollinators
Including flowering plants in your garden that attract pollinators, such as bees and butterflies, can significantly increase the fruit set and yield of your plants. Consider planting flowers like lavender, sunflowers, and bee balm to attract these important pollinators.
Herbs to attract beneficial insects
Many herbs have the ability to attract beneficial insects. For example, planting fennel can attract ladybugs, lacewings, and hoverflies, all of which are natural predators of common garden pests. By including herbs like fennel, dill, and cilantro in your garden, you create a welcoming environment for these helpful insects.
Repelling harmful insects
Companion planting can also be used to repel harmful insects. For instance, planting marigolds, nasturtiums, or garlic alongside your vegetable crops can help deter pests like aphids, whiteflies, and nematodes. These companion plants emit natural compounds that repel pests, reducing the need for chemical interventions.
Companion Planting with Herbs and Flowers
Herbs and flowers can be valuable additions to your companion planting strategy. Here are some popular herb and flower combinations that work well together.
