Companion planting is an age-old gardening technique involving strategically planting different crops to improve growth, deter pests, and attract beneficial insects. Understanding which plants thrive together can create a more productive and harmonious garden. Here are some powerful combinations to enhance your gardening success:


The Benefits of Companion Planting

Pest Control: Many companion plants naturally repel harmful insects or attract beneficial ones that prey on pests. This reduces the need for chemical pesticides and promotes a healthier garden ecosystem.


Improved Growth: Certain plants release chemicals or provide nutrients that enhance the growth of their companions. For example, basil improves the flavour and growth of tomatoes.


Disease Prevention: Companion planting can reduce the spread of diseases by creating a diverse planting environment that disrupts pest life cycles and inhibits the spread of pathogens.


Pollination: Flowers like cosmos attract pollinators, which are essential for the fruiting of many plants. This can lead to higher yields and more robust plants.


Space Utilization: Companion planting allows for efficient use of garden space by layering plants with different growth habits, such as tall plants providing shade for ground cover plants.


Plant asparagus with asters, basil, cilantro, dill, marigolds, nasturtiums, oregano, parsley, peppers, sage, and thyme. This combination not only repels nematodes that attack tomatoes and asparagus beetles but also benefits from the pest-repelling properties of these companions.


Basil is known to improve the flavour and vigour of tomatoes. It’s also a great companion for asparagus, oregano, and peppers. Additionally, basil helps repel aphids, asparagus beetles, mites, flies, mosquitoes, and tomato hornworms, making it a versatile and essential herb in any garden.


Catnip attracts pollinators and parasitoid wasps while repelling aphids, asparagus, Colorado potato beetles, and squash bugs. Planting catnip can enhance the overall health of your garden by attracting beneficial insects that keep pests in check.


Chives are excellent for improving the flavour of carrots and tomatoes. Their presence can enhance the taste of these vegetables and keep your garden flavorful and productive while attracting beneficial visitors.


Cosmos flowers attract parasitoid wasps, tachinid flies, lacewings, hoverflies, minute pirate bugs, spiders, ladybird beetles, big-eyed bugs, damsel bugs, and other predatory insects. These beneficial insects help control unwanted pest populations naturally. Cosmos can be planted throughout the garden to complement and protect.


Cucumbers thrive when planted beside asparagus, beans, celery, corn, dill, lettuce, onion, peas, radish, and tomatoes. This diverse planting strategy supports the growth of cucumbers and their companions while deterring pests.


Dill is a good companion for cabbages, cucumbers, lettuce, and onions. It attracts beneficial insects, including ladybugs and predatory wasps, which help manage pests in your garden.


Parsley likes to grow with asparagus, carrots, chives, corn, sage, onions, and tomatoes. Its presence can enhance the health and flavour of these plants, making them a valuable addition to your garden.


Strawberries grow well when planted with beans, borage, garlic, lettuce, onions, peas, spinach, and thyme. These companion plants can improve the yield and health of your strawberry patch.


Tomatoes benefit from being planted with asparagus, basil, beans, borage, carrots, celery, chives, cucumbers, garlic, lettuce, marigolds, mint, nasturtium, onion, parsley, and peppers. This diverse mix can enhance tomato growth, flavour, and pest resistance.


Yarrow attracts beneficial insects like hoverflies, ladybeetles, and wasps. Its scent also repels aphids, making it a valuable plant for protecting your garden from pests.
