Companion planting is a time-tested gardening technique that involves strategically placing different plants near each other to enhance growth, deter pests, improve soil health, and maximize space. This method leverages the natural relationships between plants, creating a more productive and resilient garden ecosystem .(Real Simple, Yale University)
🌿 Key Benefits of Companion Planting
-
Natural Pest Control: Certain plants emit scents or compounds that repel pests. For example, marigolds release aromatic chemicals that deter aphids and other insects .(Wikipedia)
-
Attracting Beneficial Insects: Flowers like sweet alyssum and calendula attract pollinators and predatory insects, such as parasitic wasps and ladybugs, which help control pest populations .(Tom's Guide)
-
Soil Enhancement: Legumes like beans and peas fix nitrogen in the soil, benefiting neighboring plants that require higher nitrogen levels .(Beaumont Enterprise)
-
Optimized Space and Shade: Tall plants can provide shade for sun-sensitive crops, while ground-covering plants suppress weeds and retain soil moisture .(Martha Stewart)
🍅 Examples of Companion Plant Pairings
-
Tomatoes: Pair with basil to repel pests like thrips and enhance flavor; marigolds can deter nematodes and aphids .(Martha Stewart)
-
Beets: Grow alongside garlic, lettuce, and bush beans to deter pests and improve soil nitrogen levels .(Homes and Gardens)
-
Cabbage Family (Brassicas): Plant near sage or dill to repel cabbage moths and other pests .(Almanac.com)
-
Carrots: Onions and chives can help repel carrot flies .(Martha Stewart)
⚠️ Plants to Avoid Pairing Together
-
Fennel: Known to inhibit the growth of many other plants; best planted separately .(extension.wvu.edu)
-
Beans and Onions: Onions can stunt the growth of beans and peas; it's advisable to plant them apart .
