What Can I Plant With Cabbage – Boost Yields And Stop Pests Naturally
Growing a big, beautiful head of cabbage is one of the most rewarding experiences a gardener can have. However, if you have ever tried it, you know that cabbage can be a bit of a magnet for pests like cabbage worms and aphids.
The good news is that you do not have to fight these battles alone. By understanding what can i plant with cabbage, you can create a mini-ecosystem that protects your crops and boosts their flavor naturally.
In this guide, I will share my years of experience in companion planting to help you choose the best neighbors for your brassicas. Whether you are a beginner or a seasoned pro, these tips will help you grow your healthiest garden yet.
The Science and Magic of Companion Planting
Companion planting is more than just a gardening tradition; it is a smart way to manage your garden’s health. When we talk about what can i plant with cabbage, we are looking for plants that provide specific benefits.
Some plants act as “bodyguards” by masking the scent of cabbage from hungry insects. Others act as “trap crops,” drawing pests away from your main harvest so the cabbage can grow undisturbed.
Additionally, certain companions help improve the soil structure or provide much-needed shade. This holistic approach reduces the need for chemical pesticides and creates a more resilient garden environment for everyone involved.
Improving Soil Health Naturally
Cabbage is a heavy feeder, meaning it pulls a lot of nutrients from the earth. Pairing it with the right neighbors ensures the soil stays balanced and fertile throughout the growing season.
Plants with shallow roots won’t compete with the deep-reaching roots of a mature cabbage. This allows both plants to thrive in the same bed without stealing each other’s “dinner” or water supply.
Maximizing Your Garden Space
If you have a small backyard or raised beds, space is at a premium. Companion planting allows you to “intercrop,” which is just a fancy way of saying you can grow two things in the same spot.
By tucking small, fast-growing plants between your slower-growing cabbages, you get two harvests for the price of one. It is an efficient way to make every square inch of your precious garden soil work for you.
what can i plant with cabbage to Repel Common Pests?
One of the biggest hurdles in growing cabbage is the dreaded cabbage white butterfly. These little flyers lay eggs that turn into hungry green caterpillars that can turn a cabbage leaf into Swiss cheese overnight.
When deciding what can i plant with cabbage to stop these pests, aromatic herbs are your best friends. Their strong scents confuse the butterflies, making it harder for them to find your cabbage heads.
I always recommend planting a “barrier” of strong-smelling plants around the perimeter of your cabbage patch. This simple trick has saved my harvests more times than I can count over the last decade.
The Power of Aromatic Herbs
- Rosemary: This woody herb has a very potent scent that masks the smell of brassicas. It is a perennial, so it can stand guard year after year.
- Sage: Sage is fantastic for deterring cabbage moths. Plus, the beautiful purple flowers attract pollinators that help the rest of your garden.
- Thyme: This low-growing herb is perfect for filling in the gaps around the base of your cabbage plants. It provides a living mulch while repelling pests.
- Dill: While some say to avoid it, I find that dill attracts beneficial wasps. These tiny “good guys” actually prey on cabbage worms, acting as a natural pest control team.
Using Alliums as a Scent Barrier
The onion family, or alliums, are perhaps the most effective companions for any cabbage variety. This includes onions, garlic, leeks, and chives.
Their pungent aroma is highly effective at warding off aphids and flea beetles. I like to plant a row of onions between my cabbage rows to create a “scent wall” that pests simply don’t want to cross.
Onions and garlic also have very different nutrient needs than cabbage. This means they can grow side-by-side without competing for the same minerals in the organic soil.
Vegetable Companions for Better Growth
Beyond pest control, some vegetables just grow better when they are near cabbage. These relationships often involve physical benefits, like providing shade or breaking up tough soil.
When you are planning what can i plant with cabbage, think about the height and growth habit of the plants. You want a diverse mix that utilizes different levels of the garden bed.
For example, tall plants can provide a bit of relief from the afternoon sun. Since cabbage likes cooler weather, a little bit of dappled shade can prevent it from bolting or becoming bitter during a heatwave.
Leafy Greens and Radishes
Lettuce and spinach are excellent companions because they grow quickly and stay low to the ground. They act as a living mulch, keeping the soil cool and moist for the cabbage roots.
Radishes are another secret weapon. They grow so fast that you can harvest them before the cabbage even starts to head up. They also help loosen the soil, making it easier for cabbage roots to expand.
Pro Tip: Plant your radishes at the same time as your cabbage seedlings. By the time the cabbage needs more space, the radishes will be on your dinner table!
The Benefits of Celery and Beets
Celery is often cited as a great neighbor for cabbage because it is thought to improve the overall health of the plant. Some gardeners even swear it improves the final flavor of the cabbage.
Beets are another solid choice. They don’t take up much room above ground, and their roots grow to a different depth than cabbage. This prevents “root competition,” which can stunt the growth of both plants.
Always remember to leave enough room for the cabbage to reach its full width. A mature cabbage can be surprisingly wide, so don’t crowd these companions too tightly against the main stem.
Flower Power: Beautiful Allies for Your Brassicas
Who says a vegetable garden can’t be beautiful? Adding flowers to your cabbage patch isn’t just about aesthetics; it’s a strategic move for a healthier harvest.
Many flowers attract “beneficial insects,” which are the predators that eat the pests we don’t want. By planting flowers, you are essentially hiring a 24/7 security team for your vegetables.
Don’t worry—these flowers are perfect for beginners! Most of them are very easy to grow from seed and require very little maintenance once they get established in the sun.
Nasturtiums: The Ultimate Trap Crop
If I could only pick one flower to plant with cabbage, it would be the nasturtium. These vibrant orange and yellow flowers are highly attractive to aphids.
By planting nasturtiums a few feet away from your cabbage, you draw the aphids to the flowers instead of your crop. This is called “trap cropping,” and it is a very effective organic gardening technique.
Nasturtiums are also edible! You can toss the peppery leaves and flowers into a salad for a beautiful and nutritious addition to your meal.
Marigolds and Calendula
Marigolds are famous in the gardening world for their ability to deter nematodes and other soil-borne pests. Their strong scent also helps keep away various flying insects that might target your cabbage.
Calendula, also known as pot marigold, is another fantastic choice. It attracts hoverflies, whose larvae have a huge appetite for aphids. It’s like having a tiny army protecting your garden.
I love the contrast of the bright orange calendula petals against the deep green or purple of the cabbage leaves. It makes the garden look like a professional landscape while doing heavy-duty work.
The “Bad Neighbors”: What to Avoid Planting Near Cabbage
Just as some plants are best friends, others are bitter enemies. Knowing what can i plant with cabbage also means knowing what to keep far away to avoid disaster.
Some plants compete too heavily for the same nutrients, while others actually attract more pests to the area. If you plant these together, you might find that both plants struggle to survive.
I always keep a small garden journal to track which pairings worked and which didn’t. Over time, you will learn the unique “personality” of your own soil and climate.
Keep Strawberries at a Distance
Strawberries and cabbage are a classic example of a bad pairing. Strawberries are known to stunt the growth of cabbage, and cabbage can negatively affect the flavor of the berries.
This is likely due to the specific chemicals these plants exude from their roots. To be safe, keep your strawberry patch in a completely different bed or at least six feet away from your brassicas.
The Heavy Feeder Conflict: Tomatoes and Peppers
While it might be tempting to put all your favorites in one bed, tomatoes and peppers are not good neighbors for cabbage. All three of these are “heavy feeders.”
If you plant them together, they will fight over the nitrogen and phosphorus in the soil. Usually, the cabbage loses this battle, resulting in small, stunted heads that never quite reach their full potential.
Additionally, tomatoes can sometimes attract similar pests or diseases that can jump over to your cabbage. It is much better to rotate these crops in different areas of your garden each year.
Avoid Pole Beans and Mustards
Pole beans can sometimes cast too much shade, preventing the cabbage from getting the light it needs to form a tight head. While bush beans are okay, give the climbing varieties some distance.
You should also avoid planting other members of the mustard family (like broccoli, kale, or cauliflower) too close together. This creates a “buffet” for pests and allows diseases like clubroot to spread rapidly.
Step-by-Step: Planning Your Cabbage Companion Layout
Now that you know the best and worst companions, let’s look at how to actually put them in the ground. A little planning goes a long way in ensuring a successful growing season.
First, choose a spot that gets at least 6 to 8 hours of sunlight. Cabbage loves the sun, but it also needs consistent moisture to keep its leaves crisp and sweet.
Follow these simple steps to set up your companion-planted bed. Remember, gardening is a journey, so don’t be afraid to experiment a little with your layout!
- Prepare the Soil: Mix in plenty of aged compost or well-rotted manure. Cabbage needs rich soil to grow those heavy heads.
- Space Your Cabbage: Plant your cabbage seedlings about 18 to 24 inches apart. This leaves room for the companions in between.
- Add the Alliums: Plant onions or garlic in the spaces between the cabbage plants. These will grow straight up and won’t crowd the cabbage.
- Tuck in the Herbs: Place herbs like thyme or sage at the corners of the bed or along the edges.
- Sow the Flowers: Scatter nasturtium or marigold seeds around the perimeter to create a protective ring.
- Mulch Well: Use straw or shredded leaves to cover the soil. This keeps moisture in and prevents weeds from moving in on your companions.
Frequently Asked Questions About what can i plant with cabbage
Can I plant cabbage and broccoli together?
While they are related, it is generally better to give them some space. Planting too many brassicas together can attract a concentrated population of pests like the cabbage looper. If you do plant them together, be extra vigilant about checking for eggs under the leaves.
Do marigolds really help cabbage?
Yes! Marigolds are excellent for deterring pests. Their scent is a natural repellent for many insects, and their roots produce a substance that can kill harmful nematodes in the soil. They are one of the most reliable companions you can choose.
What is the best herb to plant with cabbage?
When deciding what can i plant with cabbage for the best results, rosemary and sage are top contenders. Their strong, woody scents are very effective at confusing the cabbage white butterfly, which is the primary enemy of most cabbage growers.
Is it okay to plant cabbage near potatoes?
Yes, potatoes and cabbage are generally considered good companions. They don’t compete for the same space in the soil, and some gardeners believe that potatoes help repel certain beetles that might bother the cabbage.
A Final Word from Greeny Gardener
Gardening is all about working with nature rather than against it. By choosing the right companions, you are creating a diverse and healthy environment where your plants can truly thrive.
Don’t feel like you have to get everything perfect in your first season. Start with one or two companions—maybe some onions and a few marigolds—and see how your garden responds.
Now that you know what can i plant with cabbage, you are well on your way to a harvest that is not only abundant but also grown with care and intelligence. There is nothing quite like the taste of a homegrown cabbage that you protected with your own hands (and a little help from some floral friends).
So, grab your trowel, head out to the garden, and start planting. Your future coleslaw and sauerkraut will thank you! Go forth and grow!
