Whether you’re a seasoned green thumb, just starting out or looking into sustainable gardening, understanding how companion planting works can truly enhance your gardening experience.
So, let’s dive into some of the best plant combinations that will help your garden flourish and make your time in the garden even more enjoyable!
The Benefits of Companion Planting
Companion planting is more than just a clever gardening trick; it offers a range of benefits that can transform your garden into a thriving ecosystem. Here are some key advantages of using companion planting techniques:
Improved Growth and Yields
When you strategically pair plants, you can boost their growth and yields. Certain combinations enhance nutrient uptake, leading to stronger plants and bountiful harvests. For example, we suggest planting tomatoes alongside basil as it not only makes for a delicious culinary duo but also promotes healthy growth for both plants.
Natural Pest Control
One of the standout benefits of companion planting is its ability to naturally control pests. By growing plants that repel harmful insects, you can significantly reduce the need for chemical pesticides. For instance, marigolds are known for their pest-repelling properties and can be planted among vegetables to help keep aphids and nematodes at bay.
Attraction of Beneficial Insects
On the other hand companion planting also encourages a diverse range of beneficial insects to visit your garden. Ladybirds, lacewings, and bees are just a few examples of helpful critters that can be drawn in by certain plant combinations. By creating a welcoming environment for these beneficial insects, you’re ensuring natural pest control and improved pollination for your crops.
Enhanced Flavour of Certain Crops
Believe it or not, companion planting can even enhance the flavour of your produce! For instance, growing borage near strawberries is said to improve their sweetness. This simple practice can elevate the taste of your homegrown fruits and vegetables, making your meals even more delicious.
Increased Biodiversity in the Garden
Embracing companion planting promotes biodiversity, which is crucial for a healthy garden ecosystem. By mixing different plants, you create a balanced environment that supports various species, helping to reduce disease and improve soil health. A biodiverse garden is not only more resilient but also more visually appealing!
Common Companion Planting Combinations
Now that we’ve explored the benefits of companion planting, let’s dive into some popular plant pairings that can make your garden flourish. These combinations not only promote healthy growth but also enhance pest control and attract beneficial insects. Here are some tried-and-true companion planting combinations to consider:
Mint with Brassicas
Mint is a fantastic companion for brassicas like cabbage, broccoli, and cauliflower. Its strong scent confuses flea beetles, helping to protect your leafy greens from these pesky pests. Just remember to keep mint in a pot, as it can easily take over your garden!
Marigolds with Tomatoes
Adding French marigolds (Tagetes) around your tomato plants can do wonders. The vibrant flowers emit a scent that deters whiteflies and other common tomato pests. Plus, marigolds attract pollinators, making this combination a win-win for your garden.
Carrots with Leeks
Carrots and leeks make an excellent pairing thanks to their aromatic properties. The smell of leeks can help deter carrot flies, while the scent of carrots may repel leek moths. This symbiotic relationship allows both crops to thrive side by side.
Lavender with Carrots and Leeks
Lavender isn’t just a beautiful addition to your garden; it also attracts pollinators and deters pests. Planting lavender near carrots and leeks can enhance pollination and protect these crops from harmful insects. Plus, the fragrant blooms will add a delightful aroma to your garden!
Wormwood with Beans
Wormwood (Artemisia absinthium) is another powerful companion plant. Its strong scent can repel aphids from bean crops while attracting beneficial insects like lacewings and ladybirds that prey on these pests. This combination helps keep your beans healthy and thriving.
Borage with Strawberries
Borage is known for its striking blue flowers and cucumber-flavoured leaves. When planted near strawberries, borage can improve their flavour and attract pollinators like bees and butterflies, ensuring a more bountiful harvest.
Thyme with Roses
Thyme is a charming herb that makes a great companion for roses. Its strong scent can confuse pests, such as blackfly, while also attracting beneficial insects. Planting thyme near your rose bushes can enhance their beauty and protect them from unwanted pests.
Calendula with Courgettes
Calendula, with its cheerful blooms, is an excellent companion for courgettes. This vibrant flower attracts pollinators, increasing the chances of successful fertilisation for your courgette plants. Plus, calendula can deter pests, helping your courgettes grow strong and healthy.
Plant Combinations to Avoid
While companion planting can significantly enhance your garden’s health and productivity, not all plants play well together. Some combinations can hinder growth or invite pests, making it essential to know which pairings to avoid. Here are some plant combinations that simply don’t mix well, along with the reasons why:
Garlic and Onions with Beans and Peas
Garlic and onions are well-known for their strong scents, which can be effective against certain pests. However, these aromatic plants can inhibit the growth of legumes like beans and peas. Their natural compounds may prevent these crops from thriving, leading to lower yields in your garden.
Mint or Onions with Asparagus
Mint is a popular companion for many plants, but it doesn’t get along with asparagus. The aggressive growth of mint can compete with asparagus for nutrients, and onions can also have a similar effect. It’s best to plant these crops separately to ensure they all have the space and resources they need.
Cucumbers, Squashes, and Potatoes
This combination is a classic example of incompatible plants. Cucumbers and squashes can attract pests that are also drawn to potatoes, leading to an increased risk of disease and pest issues. Planting them together can create a perfect storm for your vegetable garden, so it’s wise to keep these crops apart.
Cabbages with Strawberries
While both cabbages and strawberries can flourish in the garden, they are not the best companions. Cabbage can attract pests like aphids, which may also target strawberries. This combination can lead to more pests in your garden and less fruitful plants. To protect your strawberries, it’s best to plant them away from cabbages and other brassicas.
By being mindful of these incompatible pairings, you can avoid potential setbacks in your garden and maximise the benefits of companion planting. Remember, the goal is to create a controlled environment, similar to greenhouse growing, where all your plants can thrive together!
Understanding Allelopathic Properties
Allelopathy plays a crucial role in companion planting. This natural process occurs when certain plants release chemicals into the soil that can inhibit the growth of neighbouring plants. Understanding this interaction can greatly affect the success of your garden, especially when growing vegetables. Being aware of allelopathic plants helps you make informed choices, avoiding combinations that could unintentionally suppress plant growth.
What is Allelopathy?
Allelopathy refers to the biochemical interaction between plants, where one species releases substances that can suppress or enhance the growth of others. This can be beneficial when used strategically in companion planting, but it can also lead to challenges if not properly understood. Recognising which plants possess allelopathic properties can help you make informed decisions about plant pairings and avoid potential pitfalls.
Examples of Allelopathic Plants:
Walnut Trees: Known for their powerful allelopathic effects, walnut trees release a chemical called juglone, which can be detrimental to many garden plants, including tomatoes, peppers, and potatoes. If you have walnut trees in your garden, it’s wise to keep these sensitive crops at a distance.
Sunflowers: These vibrant blooms not only brighten your garden but also produce compounds that can inhibit the growth of nearby plants like potatoes and other members of the nightshade family.
Sage: While sage is an excellent companion for many plants due to its strong aroma, it can also suppress the growth of some crops when planted too closely. This makes it essential to consider placement when planning your garden.

Our Tips for Successful Companion Planting
Now that you’re familiar with the basics of companion planting, it’s time to dive into practical tips to help you implement this method successfully in your garden. Whether you’re a beginner or an experienced gardener, these simple yet effective strategies can enhance plant health, improve yields, and keep pests at bay.
Understand Growing Conditions
The key to successful companion planting is matching plants that thrive in similar conditions. Consider the sunlight, water, and soil requirements of each plant. For instance, pairing sun-loving crops like tomatoes with marigolds works well as they both thrive in full sunlight. Conversely, avoid planting shade-lovers like lettuce next to tall plants like corn, as they may block the necessary light.
Focus on Soil Health
Healthy soil is the foundation of any thriving garden, especially when it comes to companion planting. Incorporate organic matter such as compost to enrich the soil, improve drainage, and encourage beneficial organisms. Some companion plants, like legumes (peas and beans), even fix nitrogen into the soil, benefiting neighbouring crops like leafy greens and brassicas.
Consider Plant Compatibility
When planning your garden, think about how different plants interact with each other. Companion planting isn’t just about pest control – it’s also about ensuring that plants don’t compete for the same resources. For example, fast-growing, shallow-rooted plants like lettuce work well with deep-rooted companions like carrots, as they don’t compete for space or nutrients.
Attract Beneficial Insects
One of the most powerful benefits of companion planting is its ability to attract beneficial insects like bees, ladybirds, and hoverflies. Planting aromatic herbs like thyme or flowers such as calendula can boost pollination and keep pests in check. Ensure you mix pest-repelling plants throughout your vegetable patch for maximum effect.
Practice Crop Rotation
To make the most of companion planting, consider rotating your crops each season. This helps prevent the build-up of pests and diseases while improving soil health. For example, follow nitrogen-hungry crops like tomatoes with nitrogen-fixing legumes the following year to restore the soil.
Experiment and Observe
Every garden is unique, and what works in one plot may not work in another. Companion planting involves some trial and error. Experiment with different combinations, and observe how your plants respond. Keep a gardening journal to track successes and areas that need tweaking, so you can refine your strategy over time.
By incorporating companion planting techniques into your garden, you’re not just planting seeds — you’re fostering a natural system that promotes healthier, more resilient plants. Whether it’s using aromatic herbs like basil or mint to repel pests, or attracting beneficial insects like ladybirds to boost pollination, this method offers a holistic approach to gardening that aligns with nature.
