Herb And Vegetable Companion Planting
10 Winning Herb And Vegetable Companion Planting Combinations
Companion planting is a powerful gardening technique that pairs herbs and vegetables to enhance growth, deter pests, and maximize space. Understanding which plants thrive together can create a more productive and harmonious garden ecosystem.
This blog explores essential herb and vegetable companion planting combinations and offers practical tips on how to plant them effectively. Below are examples of beneficial pairings and combinations to avoid.
1. Basil And Tomatoes
Basil and tomatoes thrive when planted together. Place your tomato plants about 18 to 24 inches apart, and position the basil around the base, spacing them 12 to 18 inches away from the tomatoes.
Ensure they consistently receive full sun and water, keeping the soil moist but well-drained. Basil helps repel flies and mosquitoes, protects tomatoes from pests, and enhances flavour.
The aromatic herb also attracts bees, boosting pollination for both the tomatoes and nearby plants.
Bonus Tip
Add marigolds to this trio to help deter nematodes and other pests.
2. Carrots And Onions
Carrots and onions are ideal companions in the garden. Plant onion sets 4 to 6 inches apart in rows, then sow carrot seeds between the onion rows, spacing them about 2 inches apart.
Onions' strong scent deters carrot flies, protecting the carrots from pests. Carrots also help loosen and aerate the soil, promoting better onion growth.
Water the space evenly to ensure both crops grow healthily. Both plants want full sun and well-drained soil.
Avoid
Don’t plant carrots near dill, as dill can stunt their growth.
3. Cucumbers And Nasturtiums
Cucumbers and nasturtiums are a great planting combination for pest control. Plant cucumber seeds or seedlings 12 to 18 inches apart in rows, and sow nasturtium seeds around the edges or between the cucumber plants, spacing them about 10 to 12 inches apart.
As a “trap crop,” nasturtiums keep cucumber beetles and whiteflies away from cucumbers while drawing aphids away from them.
Both plants prefer full sun and well-drained soil, so moisten the soil to promote healthy growth and effective pest protection.
Bonus Tip
Nasturtiums are also edible and can add a peppery flavour to salads.
4. Cabbage And Dill
Cabbage and dill make a beneficial pairing in the garden. Plant cabbage seedlings about 18 to 24 inches apart and sow dill seeds nearby, ensuring they have about 12 inches of space.
Dill attracts predatory wasps that help control cabbage worms and other pests, protecting your cabbage.
Its deep roots improve soil structure, which benefits the shallow-rooted cabbage.
Water both plants frequently to promote healthy development and pest management. They both do best in full sun and well-drained soil.
Avoid
Keep dill away from carrots, as it can inhibit their growth.
5. Spinach And Radishes
Spinach and radishes work well together, optimizing your garden space. Plant radish seeds about 1 inch apart, and sow spinach seeds 2 inches apart in the same bed.
As radishes grow quickly, they’ll help loosen the soil for the slower-growing spinach roots. Harvest the radishes within 3 to 4 weeks, just as the spinach matures, making room for the spinach to thrive. Both plants enjoy cooler weather, so plant them in early spring or fall in well-drained, fertile soil.
Avoid
Avoid planting spinach near potatoes, as they can compete for nutrients.
6. Peppers And Marjoram
Peppers and marjoram make a beneficial pairing in the garden. Plant pepper seedlings 18 to 24 inches apart in rows, and position marjoram plants nearby, spacing them about 10 to 12 inches apart.
Marjoram enhances the flavour of peppers and repels pests like aphids and spider mites, protecting them. Full light and well-drained soil are ideal for both plants. Water regularly moistens the soil, ensuring healthy growth and flavourful peppers throughout the season.
Bonus Tip
Rotate your crops every season to avoid soil erosion and lessen the accumulation of pests and diseases. This will ensure healthier plants and improved garden productivity.
7. Lettuce And Garlic
Lettuce and garlic are excellent companions in the garden. Plant garlic cloves about 4 to 6 inches apart in rows, and sow lettuce seeds between the garlic, spacing them about 6 to 12 inches apart.
The long stalks of garlic can grow later since lettuce grows swiftly and can be picked in a few weeks. Both prefer full sun and soil that drains properly, so water them frequently to encourage strong growth and efficient aphid control.
Bonus Tip
Garlic grows well alongside strawberries, carrots, and tomatoes.
8. Beans And Corn
Beans and corn are key components of the traditional ‘Three Sisters' planting method. Corn seeds are planted in rows, spaced about 12 inches apart, allowing them to grow tall as a natural trellis for beans. After the corn is approximately 6 inches tall, plant bean seeds all around it, 4 to 6 inches apart.
If adding squash, plant it between corn and beans to suppress weeds and retain moisture. Ensure all plants receive full sun and consistent watering for optimal growth.
Avoid
Don’t plant beans near onions or garlic; they can stunt bean growth.
9. Fennel And Broccoli
Fennel and broccoli are a great pairing in the garden. Plant broccoli 18 to 24 inches apart to promote healthy growth and air circulation.
Sow fennel seeds nearby, allowing at least 12 to 18 inches between the two to accommodate fennel’s larger size. Beneficial insects that attack broccoli, such as lacewings and ladybugs, are drawn to fennel.
Water frequently to encourage healthy development and pest control because both plants prefer full sun and well-drained soil.
Bonus Tip
Fennel can inhibit the growth of some nearby plants, so avoid planting it close to carrots, cilantro, or other herbs. Regularly monitor your garden to ensure all plants thrive together harmoniously.
10. Parsley And Asparagus
To successfully interplant parsley with asparagus, plant asparagus crowns in early spring, spacing them about 12-18 inches apart in well-draining soil.
Once the asparagus shoots emerge, sow parsley seeds or transplant young parsley seedlings between the asparagus plants.
This arrangement allows the taller asparagus to shade the parsley, promoting its growth while protecting it from pests like aphids. Ensure both plants receive adequate moisture and sunlight for optimal development.
Bonus Tip
Regularly harvest parsley to promote bushier growth and prevent overshadowing the asparagus. Mulching can also retain moisture and suppress weeds, benefiting both plants.

For example, fast-growing plants like radishes can be sown alongside slower growers like carrots, but if not harvested in time, they might outcompete the carrots for space and resources. Plan your planting schedule to ensure quick-growing crops are harvested before their slower counterparts mature.
4. Planting Incompatible Species
Not all plants are good companions. Some can inhibit the growth of others or attract the same pests, leading to increased competition and decreased yields.
For instance, planting beans near onions or garlic can stunt their growth—research compatible and incompatible plants to avoid detrimental pairings.
5. Neglecting Watering Needs
Different plants have different water requirements, and ignoring this can lead to issues. For example, succulents and drought-tolerant plants shouldn’t be planted alongside those that require consistently moist soil.
To make your irrigation routine easier and guarantee every plant thrives, group plants with comparable watering requirements together.
6. Failure To Monitor Plant Health
Regularly monitoring your plants is crucial for early pest detection and overall health assessment. If you notice one plant thriving while its companion struggles, it may be time to reassess its placement. Watch for symptoms of stress, such as drooping or yellowing leaves, and take quick care of any problems.
7. Disregarding Environmental Factors
Factors such as sunlight, temperature, and humidity can significantly affect plant growth. Placing sun-loving plants in shaded areas or temperature-sensitive plants in direct sunlight can lead to poor performance. Observe your garden's microclimates and position your plants according to their specific environmental needs.
8. Skipping Crop Rotation
Crop rotation is crucial to preserve soil health and avoid the accumulation of pests and diseases. Some gardeners overlook this practice, depleting soil nutrients and increasing pest problems. Each season, change the location of your plants, especially heavy feeders, to promote a balanced ecosystem.
