Welcome, fellow garden enthusiasts! In this post, we dive into the fascinating realm of companion planting, focusing our attention on the versatile and charismatic rhubarb. Rhubarb isn’t just the star of pies and jams; it’s also a fantastic companion in your garden, enhancing the growth and well-being of its plant neighbors. So, grab your gardening gloves and join me on this journey as we unlock the secrets of companion planting with rhubarb.
Understanding Rhubarb
Before we delve into the intricate dance of companion planting, let’s take a moment to appreciate the wonder that is rhubarb. Known scientifically as Rheum rhabarbarum, rhubarb is a cool-season perennial vegetable with vibrant, thick stalks and large, fan-like leaves. While its tart flavor makes it a favorite in the culinary world, rhubarb’s value extends beyond the kitchen.
Rhubarb is an excellent source of nutrients like vitamin C, potassium, and dietary fiber. Its medicinal properties have been recognized for centuries, with traditional medicine utilizing rhubarb for its potential to aid digestion and support overall health. But what makes rhubarb truly unique is its role in the garden as a companion plant.

The Benefits of Companion Planting
Companion planting is a gardening technique that involves strategically placing different plants together to promote mutual benefits. These benefits can include improved pest control, enhanced pollination, increased nutrient uptake, and overall healthier plant growth. By harnessing the power of companion planting, gardeners can create a balanced ecosystem where plants work together harmoniously.
Rhubarb, with its robust nature and unique qualities, is an excellent team player in the garden. Let’s explore the various benefits of companion planting with rhubarb.
- Pest Control: Rhubarb as a Guardian
One of rhubarb’s superhero qualities is its ability to deter certain pests with its toxic leaves. The oxalic acid present in rhubarb leaves acts as a natural insect repellent. Planting rhubarb alongside susceptible crops can provide a protective barrier, discouraging pests like aphids and beetles from making a feast of your garden.
For instance, consider planting rhubarb near your prized cabbage or broccoli. These cruciferous vegetables often fall victim to cabbage worms and aphids, but with rhubarb standing guard, you create a pest-resistant fortress.
- Soil Enrichment: Rhubarb’s Generosity
Rhubarb is not just a guardian; it’s also a generous giver. This plant has a deep root system that reaches down into the soil, drawing up essential nutrients. As rhubarb leaves break down, they contribute organic matter to the soil, enriching it and creating a fertile environment for neighboring plants.
When strategically placed, rhubarb can be a boon to nutrient-hungry companions. Try pairing rhubarb with nitrogen-loving plants like beans or peas. Rhubarb’s nutrient-absorbing roots will help break up compacted soil, allowing the legumes to fix nitrogen and benefit from the enriched soil.
- Weed Suppression: Rhubarb’s Ground Cover
Tired of battling relentless weeds in your garden? Rhubarb might just be the ally you need. With its large, overlapping leaves, rhubarb creates a natural ground cover that shades the soil beneath. This shading effect inhibits weed growth, reducing the competition for water, nutrients, and sunlight.
Consider planting rhubarb around perennial crops like strawberries or asparagus. The dense foliage will not only suppress weeds but also provide a living mulch that conserves soil moisture and maintains a more stable soil temperature.
- Attracting Pollinators: Rhubarb’s Blooming Beauty
While rhubarb is primarily grown for its stems, it produces tall, attractive flower stalks that burst into bloom. These flowers are a beacon for pollinators, such as bees and butterflies, which play a crucial role in the reproduction of many fruit and vegetable crops.
Strategically placing rhubarb near fruit trees or berry bushes can enhance pollination and boost fruit yields. The nectar-rich flowers of rhubarb act as a welcome pitstop for pollinators, ensuring a steady flow of these essential garden workers.
Companion Planting with Rhubarb
Now that we’ve explored the myriad benefits of companion planting with rhubarb, let’s get down to the nitty-gritty and discuss some practical pairings for a thriving garden.
- Rhubarb and Beans/Peas: A Nutrient-Packed Duo
Beans and peas, known for their ability to fix nitrogen in the soil, make excellent companions for rhubarb. The legumes benefit from the enriched soil created by rhubarb’s deep root system, while rhubarb, in turn, enjoys the nitrogen boost provided by its green companions.
Plant rhubarb on the north side of your bean or pea rows to avoid shading these sun-loving legumes. This partnership creates a dynamic duo that promotes healthy growth and higher yields.
Caution: While we recommend the pairing of rhubarb with beans and peas for the nitrogen-fixing benefits, it’s essential to exercise caution. Introducing too many nitrogen-fixing plants in close proximity, including beans and peas, can lead to an excess of nitrogen in the soil.
Rhubarb, although benefiting from nitrogen, has its limits. An overload of nitrogen can result in overly lush foliage at the expense of robust stalk development. To strike the right balance, provide enough space between rhubarb and legumes, allowing them to collaborate without overwhelming the rhubarb.
- Rhubarb and Brassicas: Guardians of the Greens
Brassicas, including cabbage, broccoli, and kale, often face the wrath of cabbage worms and aphids. Enter rhubarb, the guardian of the greens. Planting rhubarb around your brassicas creates a protective barrier, deterring pests and reducing the need for chemical interventions.
Ensure that rhubarb is positioned to the south or west of your brassica patch to avoid shading these sun-loving vegetables. This strategic arrangement forms a natural defense system that keeps your cruciferous crops pest-free.
- Rhubarb and Strawberries: A Berry Bliss Alliance
Strawberries and rhubarb aren’t just a match made in dessert heaven; they also thrive as companions in the garden. Rhubarb’s dense foliage acts as a natural mulch, suppressing weeds and conserving soil moisture, which is particularly beneficial for the shallow-rooted strawberries.
Plant rhubarb at the edges or between rows of strawberries, allowing the two to coexist harmoniously. This partnership not only enhances the health of both plants but also brings a delightful pairing to your garden landscape.
Caution: While we recommend the partnership of rhubarb and strawberries, it’s essential to note that continuous planting of strawberries alongside rhubarb may not be ideal. Both plants are susceptible to certain diseases, and planting them in the same location year after year can increase the risk of disease transmission.
Practice crop rotation and avoid planting strawberries in the same spot where rhubarb grew the previous season. This simple precautionary measure helps break the disease cycle and maintains a healthier growing environment.
- Rhubarb and Fruit Trees: Orchestrating Pollination
Fruit trees, such as apple or cherry, can benefit from the presence of rhubarb in their vicinity. The tall flower stalks of rhubarb attract pollinators that play a vital role in fruit set and development. Bees and butterflies, drawn to the nectar-rich flowers of rhubarb, become active pollinators for your fruit trees.
Consider planting rhubarb at the borders or within the drip line of your fruit trees. This strategic placement creates a visually appealing and functional partnership that encourages a bountiful harvest.
- Rhubarb and Garlic/Onions: A Pungent Partnership
If you’re a fan of culinary delights and want to boost the health of your allium crops, consider planting rhubarb alongside garlic and onions. Rhubarb’s pest-repelling properties can help keep onion flies and aphids at bay, providing a protective shield for your aromatic alliums.
Position rhubarb on the south or east side of your garlic or onion beds to avoid shading these sun-loving crops. This collaboration not only contributes to a safer, pest-resistant environment but also adds a pungent twist to your gardening endeavors.
- Rhubarb and Carrots: Beneath the Soil Harmony
Carrots, with their delicate roots, often benefit from companions that can help deter pests and improve soil structure. Enter rhubarb, a subterranean ally for your crunchy orange delights. The deep-rooted nature of rhubarb helps break up compacted soil, creating a more hospitable environment for carrots to grow long and straight.
Plant rhubarb in proximity to your carrot rows, allowing them to share the underground space without competing for nutrients. This dynamic duo creates a harmonious relationship that fosters healthy root development and tastier carrots come harvest time.
- Rhubarb and Lettuce/Spinach: Shade and Shield
For those leafy greens in your garden, rhubarb can play the role of both shade provider and pest deterrent. Lettuce and spinach, with their tender leaves, benefit from the large, rhubarb leaves that create a protective canopy, shielding them from intense sunlight and reducing the risk of bolting.
Plant rhubarb on the west side of your lettuce or spinach beds, allowing the afternoon sun to be filtered through the rhubarb leaves. This not only protects your greens but also provides a picturesque garden scene of contrasting foliage.
- Rhubarb and Tomatoes: The Dynamic Duo of Flavor
Tomatoes and rhubarb might seem like an unconventional pair, but their alliance can yield delightful results. Rhubarb’s ability to deter certain pests can benefit tomatoes, especially against aphids and nematodes. Moreover, the enriched soil created by rhubarb’s deep roots provides a nutrient-rich foundation for tomato plants.
Plant rhubarb on the outskirts or within the tomato patch, ensuring that it doesn’t overshadow the sun-loving tomatoes. This partnership not only enhances the flavor of your tomatoes but also contributes to a healthier, more robust crop.
- Rhubarb and Herbs: A Flavorful Garden Tapestry
If you’re a fan of cultivating an herb garden, rhubarb can be an excellent companion for various herbs. The protective nature of rhubarb can help shield herbs like basil, cilantro, or parsley from pests, creating a diverse and flavorful garden tapestry.
Integrate rhubarb along the edges or between herb beds, allowing for a visually appealing arrangement. This not only promotes a thriving herb garden but also adds a touch of whimsy to your overall garden design.
- Rhubarb and Pumpkins/Squash: Spreading Vines, Controlled
For those who love growing sprawling vines like pumpkins or squash, rhubarb can be a strategic partner. Rhubarb’s upright growth habit provides a natural trellis for the sprawling vines, preventing them from overtaking your garden space.
Plant rhubarb at the north or northeast side of your pumpkin or squash hills, ensuring they receive ample sunlight. This collaborative effort not only keeps your garden organized but also allows for efficient use of space and resources.
As we’ve uncovered, the world of companion planting with rhubarb is vast and filled with exciting possibilities. From warding off pests to enriching the soil and enhancing flavors, rhubarb proves to be an invaluable ally in the garden. Feel free to mix and match these companion planting ideas based on your gardening goals and preferences. The beauty of companion planting lies in the experimentation, observation, and the joy of discovering the unique dynamics that unfold in your garden.

Asparagus, another perennial vegetable, may not be the best bedfellow for rhubarb due to their conflicting root systems. Rhubarb’s deep roots can encroach upon the space that asparagus needs for its extensive root network. This can lead to competition for nutrients and water, potentially impacting the overall health and productivity of both crops.
Consider giving each plant its designated area in the garden, ensuring they have ample room to spread their roots without encroaching on each other’s territory.
3. Rhubarb and Mint: The Invasive Intruder
Mint, with its vigorous growth and invasive nature, might not be the best companion for rhubarb. Mint tends to spread rapidly and can overrun the space, potentially smothering the growth of rhubarb. Additionally, rhubarb’s preference for well-drained soil may clash with mint’s ability to thrive in damper conditions.
If you’re keen on having both in your garden, consider planting mint in containers to control its spread or designate a separate area for this aromatic herb.
In the intricate dance of companion planting, knowing what not to plant with rhubarb is just as crucial as understanding its beneficial partnerships. By avoiding potential clashes and conflicts, you pave the way for a garden where each plant can thrive independently and contribute to the overall beauty and productivity of your green haven.
Final Thoughts
In the intricate dance of the garden, rhubarb emerges as a versatile partner, contributing its unique strengths to the collective well-being of its companions. From pest control and soil enrichment to weed suppression and enhanced pollination, rhubarb’s role in companion planting is truly multifaceted.
As you embark on your gardening journey, consider the potential of rhubarb to elevate your garden’s harmony.
