In garden landscaping, companion plants refer to combinations of different plant species that are strategically planted together to benefit each other in various ways. These combinations can provide mutual support, protect against pests, improve soil quality, and enhance the overall aesthetics of a garden. Here are some common examples of companion plants that can be used in garden landscaping:
1. Marigolds (Tagetes) and Tomatoes
Marigolds have a strong scent that repels many pests, including nematodes that can damage tomato plants. By planting marigolds near tomato plants, the marigolds act as a natural pest deterrent, reducing the need for chemical pesticides.
2. Basil and Tomatoes
Basil is a fragrant herb that can improve the flavor of tomatoes when planted nearby. It also repels certain pests like flies and mosquitoes. In turn, tomatoes provide shade for the basil plants, helping them thrive in hot weather.
3. Nasturtiums (Tropaeolum) and Cucumbers
Nasturtiums attract aphids away from cucumber plants, acting as a sacrificial trap crop. They also add a pop of color to the garden. Additionally, the strong scent of nasturtiums can deter squash bugs, which are common pests for cucumbers.
4. Sunflowers and Corn
When sunflowers are planted around the perimeter of a cornfield, they can attract beneficial insects such as ladybugs and lacewings. These insects prey on pests, like aphids and corn earworms, helping to protect the corn crop naturally.
5. Chives and Roses
Chives have strong-smelling leaves that repel aphids, a common pest for rose bushes. By planting chives alongside roses, they serve as a natural pest deterrent and help to keep the roses healthy.
6. Carrots and Onions
When carrots and onions are interplanted, they can help repel pests such as carrot flies and onion maggots. The strong smell of onions can mask the scent of carrots, making them less attractive to pests.
7. Dill and Cabbage
Dill attracts beneficial insects like ladybugs and parasitic wasps, which prey on pests that commonly affect cabbage plants, such as cabbage loopers and aphids. Planting dill near cabbage helps to naturally control these pests.
8. Lavender and Roses
Lavender is known for its aromatic fragrance and can attract pollinators like bees and butterflies. By planting lavender near roses, it can help increase pollination and improve the overall health and vigor of the rose bushes.
9. Mint and Peppers
Mint acts as a natural repellent for pests like ants and aphids. By planting mint near pepper plants, it can help protect them from these pests. However, mint can be invasive, so it is recommended to plant it in containers to keep it from spreading uncontrollably.
10. Potatoes and Marjoram
Marjoram has a strong scent that can deter pests like potato beetles from damaging potato plants. Planting marjoram near potatoes can help protect the crop and improve its overall yield.
Conclusion
Companion planting in garden landscaping offers many benefits. It can help reduce the need for chemical pesticides, attract beneficial insects, improve pollination, and enhance the flavor and health of plants. By strategically choosing and interplanting companion plants, gardeners can create a more balanced and harmonious ecosystem within their garden.
