These are just a few examples of the many companion plants that can be used in edible landscaping. By incorporating these plants into your garden, you can create a healthy and thriving ecosystem that is naturally resistant to pests and diseases.
Benefits of Companion Planting in Edible Landscaping
Companion planting is the practice of growing different plants together in order to benefit each other. In edible landscaping, companion planting can aid in organic pest control, as well as provide a range of other benefits.
- Natural pest control: Some plants repel pests, while others attract beneficial insects that prey on them. For example, planting marigolds with your vegetables can help to repel nematodes, while planting parsley can attract ladybirds, which will eat aphids.
- Improved soil health: Some plants, such as legumes, have the ability to fix nitrogen in the soil. By planting legumes alongside your vegetables, you can improve soil fertility without the need for chemical fertilizers.

How to Plan Your Companion Planting Layout
Companion planting is not just about planting different plants together but also planning your layout thoughtfully. The following steps can help you plan your companion planting layout:
- Choose the right plants: Before planning your layout, choose the right plants that you want to grow. Make sure to select plants that grow well together and have compatible needs for sunlight, water, and soil nutrients.
- Group plants according to their needs: Group plants with similar needs in terms of sunlight, water, and soil nutrients together. This helps to ensure that all plants in the group get the necessary conditions for their growth.
- Select companion plants: Once you have selected the main plants, it's time to choose companion plants. Companion plants are those that can help the main plants by repelling pests or attracting beneficial insects.
- Plant the tallest plants first: Start by planting the tallest plants in the back of the bed or container. This helps to ensure that all plants get access to sunlight, and the tall plants don't overshadow the shorter ones.
- Plant companion plants next: Plant the companion plants around the main plants in a way that maximizes their benefits. For example, plant marigolds around tomatoes to repel nematodes.
- Fill the gaps: Finally, fill any remaining gaps with smaller plants that complement the main plants and companion plants. This helps to create a cohesive and visually appealing layout.
By following these steps, you can create a companion planting layout that not only looks beautiful but also helps to control pests organically.
Common Mistakes to Avoid in Companion Planting
Companion planting is a great technique to incorporate in your organic pest control strategy. However, it is important to keep in mind that not all plant combinations work well together. Here are some common mistakes to avoid when planning your companion planting:
- Planting incompatible plants together: Certain plants can have adverse effects on their neighboring plants. For example, onions and garlic can inhibit the growth of beans and peas, while fennel can stunt the growth of tomatoes and other plants in the same family. Research which plants are compatible with each other before planting.
- Planting too close together: While companion planting involves planting different types of plants next to each other, it is important to give each plant enough space to grow and thrive. Planting too close together can lead to overcrowding and competition for resources like water and nutrients. Make sure to research the spacing requirements for each plant before planting.
- Not rotating crops: Companion planting is not a substitute for crop rotation. Planting the same crops in the same spot year after year can lead to a buildup of pests and diseases in the soil. Make sure to rotate crops to prevent this from happening.
- Ignoring soil pH: Different plants thrive in different soil pH levels. For example, blueberries prefer acid soil, while spinach prefers a more neutral pH level. Make sure to consider the soil pH requirements of each plant when planning your companion planting.
- Not considering plant height: When planning your companion planting, it is important to consider the height of each plant. Taller plants can shade out shorter plants, preventing them from getting enough sunlight. Make sure to plant taller plants where they will not shade out shorter plants.
- Not considering watering requirements: Different plants have different watering requirements. For example, tomatoes need frequent watering, while drought-tolerant plants like sage and thyme prefer less watering. Make sure to group plants together based on their watering requirements to avoid over- or under-watering.
By avoiding these common mistakes, you can create a successful companion planting strategy that will help control pests and diseases in your edible landscape. Remember to do your research and plan accordingly for each plant's needs.
Success Stories of Companion Planting in Edible Landscaping
Companion planting is an effective technique that can help you maximize your yield by planting different crops together in the same space. Some plants can help repel pests, while others can enhance the soil quality. Here are some of the success stories of companion planting in edible landscaping:
Tomatoes, Basil, and Marigolds: Planting marigolds near tomatoes and basil can help repel nematodes, which are plant-parasitic worms that can harm your crops. Marigolds can also attract beneficial insects, such as ladybugs and lacewings, which prey on pests like aphids and spider mites. Additionally, basil can improve the flavor of tomatoes and also repel pests.
Corn, Beans, and Squash: Known as the "Three Sisters," these three crops have a symbiotic relationship that can improve soil quality and yield. Corn provides support for beans to climb, while beans fix nitrogen in the soil, which can benefit both corn and squash. Meanwhile, squash can provide ground cover, which can suppress weeds and retain moisture.
Lavender and Rosemary: Both lavender and rosemary have strong fragrances that can repel pests like moths and slugs. Additionally, they can attract beneficial insects, such as bees and butterflies, which can pollinate your crops and also prey on pests like aphids and whiteflies.
Nasturtiums and Cucumbers: Nasturtiums can attract aphids away from cucumbers, which are susceptible to aphid infestations. Nasturtiums can also provide ground cover, which can suppress weeds and retain moisture. Additionally, the flowers and leaves of nasturtiums are edible and can add a peppery flavor to your salads.
Chives and Carrots: Chives can help deter pests like carrot rust flies, which can harm your carrot crops. Additionally, chives can attract beneficial insects, such as hoverflies and parasitic wasps, which can prey on pests like aphids and caterpillars.
Companion planting can be an effective way to promote a healthy and diverse ecosystem in your edible landscape. By planting different crops together, you can reduce the need for harmful pesticides and fertilizers, and also improve soil quality and yield. Experiment with different combinations and see what works best for your garden!
