What Are Companion Plants?
Companion plants are nature’s little helpers, carefully selected to grow alongside your main crop and provide mutual benefits. It’s like having a team of tiny gardeners working tirelessly to keep your plants healthy and happy. These companions can do everything from repelling pests and attracting beneficial insects to improving soil quality and even boosting flavor.
The Best Companions Plants for Broccoli
Now, let’s dive into the star-studded cast of companion plants for broccoli that can make your broccoli patch thrive like never before!
Root Crops
Radishes, beets, carrots, turnips, and rutabagas make excellent root crop companion plants for broccoli patches. These unassuming veggies do more than just add variety to your harvest – they play a crucial role in keeping your soil healthy and aerated.
Radishes, with their pungent flavor and vibrant hues, are quick-growing companions that can help loosen the soil with their spindly roots. Plus, they act as a trap crop, luring pesky root flies away from your prized broccoli. Learn how to grow radish.
Beets, those ruby-red beauties, are more than just a colorful addition to your salads. Their deep taproots help break up compacted soil, allowing your broccoli’s roots to spread and access vital nutrients more efficiently.
Carrots, the quintessential root crop, make excellent neighbors for broccoli. Their feathery tops provide light shade, helping to retain moisture in the soil, while their roots delve deep, aerating the earth as they grow.
Turnips, with their bold flavor and hardy nature, can withstand cooler temperatures, making them ideal for extending your growing season alongside broccoli. Their sprawling greens also help suppress weeds, keeping your garden tidy.
Last but not least, rutabagas, those unsung heroes of the root veggie world, bring a unique blend of flavors to your garden. Their deep roots help break through tough soil, while their leafy tops provide additional ground cover and shade for your broccoli plants.
Aromatic Herbs
Dill, rosemary, sage, thyme, and basil are the fragrant ambassadors of the herb world, and they make fantastic companion plants for broccoli. Not only do they add a delightful aroma to your garden, but they also serve as natural pest deterrents, keeping those pesky critters at bay.
Dill, with its feathery foliage and distinctive flavor, is a true multitasker in the garden. Its umbels attract beneficial insects like ladybugs and lacewings, which feast on aphids and other pests that might threaten your broccoli crop.
Rosemary, a hardy evergreen shrub, is more than just a culinary delight. Its strong scent confuses and repels many common garden pests, including cabbage moths and carrot flies, making it an invaluable ally for your broccoli patch. Learn how to propagate rosemary.

Last but not least, basil, the beloved herb of Italian cuisine, is a must-have in any broccoli companion garden. Its strong scent confuses and deters aphids, thrips, and spider mites, while its delicate flowers attract pollinators to your patch. Learn how to plant basil.
Flowering Plants
Marigolds, nasturtiums, alyssum, calendulas, and cosmos are the cheerleaders of the plant world, adding vibrant pops of color to your broccoli patch while attracting a host of beneficial insects to keep your crop healthy and thriving as companion plants for broccoli.
Marigolds, with their bold orange and yellow blooms, are a gardener’s best friend. Not only do they attract pollinators like bees and ladybugs, but they also release compounds that deter nematodes, whiteflies, and other pests that might target your broccoli. Learn how to grow marigolds.
Nasturtiums, with their edible flowers and peppery leaves, are more than just a pretty face. These trailing plants act as a trap crop, luring aphids and other pests away from your broccoli while also providing ground cover to suppress weeds.
Alyssum, a low-growing annual, forms a carpet of tiny white or purple flowers that are irresistible to beneficial insects like parasitic wasps and lacewings. These predators will gladly patrol your garden, keeping pest populations in check.
Calendulas, also known as pot marigolds, are a stunning addition to any garden. Their bright orange blooms attract hoverflies and other pollinators, while their pungent odor deters rabbits and deer from nibbling on your precious broccoli.
Cosmos, with their delicate petals and airy foliage, are a magnet for bees, butterflies, and other pollinators. These graceful flowers not only add a touch of whimsy to your garden but also help ensure a bountiful broccoli harvest through their pollination services.
Other Vegetables
Spinach, onions, potatoes, lettuce, and bush beans make excellent veggie companions for your broccoli patch, each offering unique benefits to help your cruciferous crop thrive.
Spinach, a nutrient-dense leafy green, provides excellent ground cover and helps retain moisture in the soil. Its shallow roots don’t compete with your broccoli’s deeper ones, making it an ideal planting partner.
Onions, with their pungent aroma, are natural pest deterrents. Their strong scent confuses and repels aphids, cabbage worms, and other common broccoli pests, while their shallow roots aerate the soil and allow for better water infiltration. Learn how to plant onions.
Potatoes, those humble tubers, make surprisingly good companions for broccoli. Their broad leaves provide shade and help retain soil moisture, while their roots help break up compacted soil, allowing your broccoli’s roots to spread more easily. Learn how to plant potatoes.
Lettuce, a cool-weather crop, is a perfect pairing for broccoli. Its shallow roots don’t compete with your broccoli’s deeper ones, and its low-growing habit provides ground cover to suppress weeds and retain soil moisture.
Bush beans, with their nitrogen-fixing capabilities, help enrich the soil with vital nutrients that your broccoli plants crave. Their compact growth habit means they won’t overshadow your cruciferous crop, making them an ideal space-saving companion.

Plants to Avoid with Broccoli
While companion planting can work wonders for your broccoli patch, some plants simply don’t make good neighbors. These incompatible companions can compete for resources, stunt growth, or even attract pests that could harm your beloved cruciferous crop.
Tomatoes
These juicy fruits can actually stunt the growth of your broccoli plants, so it’s best to keep them separated. Tomatoes and broccoli have different nutrient and environmental requirements, making it challenging for both crops to thrive when planted together.
Strawberries
While strawberries are delicious, they’re not the best buddies for broccoli. Their sprawling runners can compete for nutrients and water, leaving your cruciferous crop feeling neglected. Additionally, strawberries can harbor pests like spider mites, which could easily spread to your broccoli plants.
Pole Beans
These climbing vines can quickly overshadow and shade your broccoli plants, blocking out the precious sunlight they need to thrive. Pole beans also have aggressive root systems that can out-compete your broccoli for water and nutrients.
Fennel
With its strong licorice-like aroma, fennel can actually stunt the growth of broccoli and other members of the brassica family. This pungent herb also attracts cabbage moths and other pests that could wreak havoc on your broccoli crop.
Mustard Greens
While mustard greens are part of the brassica family, they’re not the best companions for broccoli. These spicy greens can attract the same pests that target broccoli, leading to an infestation that could decimate your entire crop.
Nightshades
Plants from the nightshade family, such as eggplants and peppers, should be kept away from your broccoli patch. Like tomatoes, these crops can stunt the growth of your broccoli and potentially harbor pests or diseases that could spread.
| Plants to Avoid with Broccoli | Reason to Avoid |
| Tomatoes | Can stunt broccoli growth, different nutrient and environmental requirements |
| Strawberries | Compete for nutrients and water, can harbor pests like spider mites |
| Pole Beans | Overshadow and shade broccoli plants, aggressive root systems compete for resources |
| Fennel | Can stunt growth of broccoli and other brassicas, attracts cabbage moths and other pests |
| Mustard Greens | Attract the same pests that target broccoli, leading to potential infestations |
| Nightshades (eggplants, peppers) | Can stunt broccoli growth, harbor pests or diseases that could spread |
By avoiding these incompatible plants and focusing on the best companion options, you’ll create a harmonious garden ecosystem that supports your broccoli’s growth and keeps pests at bay.
