What is Companion Planting?
At its core, companion planting involves strategically placing different plants near each other to create a mutually beneficial environment. It’s a time-honored technique, often rooted in traditional farming practices, that respects the complex relationships within nature. Instead of relying solely on chemical solutions, companion planting leverages these natural interactions to create a healthier, more resilient garden ecosystem. Think of it as a community where plants support each other, much like a real neighborhood.
Why Should Beginners Care About Companion Planting?
For beginners, companion planting can feel like an advanced skill, but it’s actually quite accessible and beneficial right from the start. Here’s why it’s worth considering:
- Reduced Pest Problems: By attracting beneficial insects and deterring pests, you’ll need fewer interventions to keep your plants healthy.
- Improved Soil Health: Certain plants can enrich the soil, making it more fertile for others.
- Increased Yields: By creating a better growing environment, companion planting can lead to more abundant harvests.
- Less Chemical Use: Natural pest control and soil enrichment mean you can garden more organically.
- A More Diverse Garden: Experimenting with companion planting encourages you to grow a wider variety of plants.
Key Principles of Companion Planting
Before you start mixing and matching plants willy-nilly, let’s delve into some of the foundational principles:
Repelling Pests
Certain plants, like marigolds and basil, naturally emit strong scents that can confuse or deter pests. For example, marigolds are well-known for repelling nematodes and other harmful insects, making them excellent companions for vegetables like tomatoes and peppers. Here’s a great list of pest-repelling plants.
Attracting Beneficial Insects
Having a diverse garden is essential for attracting beneficial insects. These include pollinators like bees and butterflies, as well as predatory insects like ladybugs and lacewings that feed on pests. Herbs like dill, fennel, and yarrow are excellent at attracting these helpful insects. Learn more about how to attract beneficial insects to your garden.
Nitrogen Fixation
Legumes, like beans and peas, have a unique ability to “fix” nitrogen from the air into the soil. This is a huge benefit to plants that need nitrogen to grow. This natural fertilization means that you don’t need as much fertilizer and your plants will be stronger and healthier. Consider planting beans near crops such as corn, squash and even greens.
Providing Physical Support
Some plants can physically support others, acting as a natural trellis. For example, corn stalks can provide a support structure for vining plants like pole beans. This is a symbiotic relationship, where the corn benefits from the beans fixing nitrogen, while the beans have a place to climb.
Improving Soil Structure
Different plants have different root structures that can break up the soil, improving aeration and drainage. Deep-rooted plants can also draw up nutrients from lower levels, making them available to shallower-rooted plants. Consider a mix of roots when planting for optimal soil structure.
Shade and Shelter
Taller plants like sunflowers can provide shade for more delicate plants that might struggle in intense sunlight. This can help prevent scorching and keep the soil cooler and moist. Similarly, ground cover plants can help to shade the soil and suppress weeds. This is an important aspect when dealing with a very hot climate, or delicate crops.
Common Companion Planting Combinations
Now, let’s dive into some specific companion planting combinations you can try in your garden:
The Three Sisters
This classic combination is a Native American tradition involving corn, beans, and squash. The corn provides support for the beans to climb, the beans fix nitrogen in the soil, and the large leaves of the squash help to shade the soil and suppress weeds. It’s an almost perfect example of the power of companion planting.
Tomatoes and Basil
Basil not only tastes great, but it also repels pests like tomato hornworms and whiteflies. It is also said to improve the flavor of tomatoes. Plant these two together and you’ll see healthier, more productive tomato plants. This combo is easy to fit into small gardens or containers.
Carrots and Onions
The strong scent of onions repels carrot flies, while the scent of carrots is said to deter onion flies. This is an excellent example of mutual protection, keeping both crops safe. Leeks also offer similar benefits. Here’s more on companion planting with root vegetables.
Cabbage and Rosemary
Rosemary has a strong aroma that can deter cabbage moths, which are notorious for laying eggs on cabbage leaves. Planting rosemary nearby will also add variety to your garden and can be used fresh, or dried.
Cucumbers and Dill
Dill is excellent for attracting beneficial insects that prey on cucumber pests. It also enhances the overall health of the cucumber plants. Dill is easy to grow and will also provide a welcome addition to many recipes.
Lettuce and Chives
Chives have a strong odor that can repel many pests, while lettuce appreciates the shade provided by the larger, taller chive plant. Learn more about pairing leafy greens and herbs.
Peppers and Petunias
Petunias can attract beneficial insects and repel aphids, which can be a nuisance for pepper plants. The vibrant flowers also add color and beauty to your garden, making it a delightful place to visit.
Garlic and Roses
Garlic is known for its pest-repelling properties and can help protect roses from aphids and other pests. It also improves the health of the soil, which is especially important for healthy rose bushes. Plus, it’s a great two-for-one when harvesting time comes.
Mint and Cabbage
Mint is a natural repellent of cabbage moths, flies and many other pests. It can also be planted near tomatoes, rosemary and other common garden plants. Mint spreads easily, so consider keeping it in a container to prevent overgrowth.
Beets and Onions
Just as with carrots and onions, these root vegetables thrive when planted together. Onion’s strong scent helps deter many of the pests that would enjoy eating beets.
Plants to Avoid Placing Together
While companion planting is all about beneficial relationships, it’s equally important to know which plants don’t get along. Here are some pairings to avoid:
Fennel with Most Vegetables
Fennel can inhibit the growth of many vegetables, including beans, tomatoes, and cabbage. It’s a strong plant and should be kept away from most other garden vegetables. It’s best to plant it in a separate area.
Onions and Beans
Onions can inhibit the growth of beans, so it’s best to keep them separate. While onions are great companions to other vegetables, legumes prefer to be on their own, or with crops that are not from the allium family.
Potatoes and Tomatoes
Both potatoes and tomatoes belong to the same family and are susceptible to similar diseases. Planting them close together can make disease spread more easily between the plants. It’s best to rotate them through the garden and never grow them side-by-side.
Brassicas and Strawberries
Plants in the brassica family (such as broccoli, cauliflower, and cabbage) may stunt the growth of strawberries. Strawberries tend to prefer living in groups with other compatible plants.
Sunflowers and Potatoes
Sunflowers can sometimes inhibit the growth of potatoes and other plants by competing for resources like water and nutrients. They are also known to attract diseases that may pass over to other vegetables.
