Rhubarb Companion Plants
For many gardeners, the rich, deep hues of rhubarb stalks signify the onset of warmer months and the promise of desserts to come.
Beyond its culinary fame, however, lies a lesser-known but equally important facet of the rhubarb plant: its potential in the world of companion planting.
Rhubarb, with its broad leaves and distinctive growth pattern, interacts with its surrounding plants.
When strategically placed in a garden, rhubarb can serve multiple roles.
It not only aids other plants in their growth but can also be a shield against certain pests.
Additionally, certain plants can boost rhubarb's vitality, ensuring a healthier, more bountiful harvest.
But why does companion planting with rhubarb matter?
Firstly, understanding these relationships can save gardeners time and effort by reducing the need for chemical pest controls and fertilizers.
A well-organized garden, where rhubarb companions are strategically placed, can harness nature's own methods to achieve balance and promote health.
Secondly, understanding these interactions can yield a more prolific harvest, both of rhubarb and its neighboring plants.
With the right companions, rhubarb can flourish and provide even more of those tart, delicious stalks for springtime recipes.

Benefits of Rhubarb in the Garden
Rhubarb, while commonly recognized for its bright pink stalks and role in delicious desserts, also stands tall as a formidable ally in the garden ecosystem.
This perennial favorite offers several advantages, making it an essential player in holistic and sustainable gardening.
Deters Pests:
While rhubarb may be enticing to us humans, especially in a pie, certain pests find it repelling.
Many gardeners have fewer issues with pests like leaf beetles when rhubarb is nearby.
This means that the surrounding plants benefit from this natural shield, reducing the damage and ensuring healthier growth.
Living Mulch:
Beyond its pest-repelling properties, rhubarb has another ace up its sleeve.
Its large, expansive leaves sprawl across the garden floor, acting as a natural ground cover.
This "living mulch" maintains soil moisture, prevents excessive evaporation on hot days, and curbs the growth of unwanted weeds.
With its shade, rhubarb also aids in preserving the soil's organic matter, leading to richer, more fertile ground over time.
Soil Enrichment:
The deep-rooted nature of rhubarb means it can draw nutrients from deeper soil layers, which are often untapped by other plants.
As the rhubarb plant sheds its leaves and they decompose, these nutrients are returned to the topsoil, benefiting the plants around it.

Best Companion Plants for Rhubarb
In the choreographed dance of companion planting, certain plants share a special relationship with rhubarb.
These harmonious interactions lead to enhanced growth, reduced pest issues, and a thriving garden.
Let's explore the top contenders that make excellent neighbors for rhubarb:
Strawberries
The mention of strawberries and rhubarb together often evokes thoughts of delicious pies and jams.
But their harmony extends beyond the kitchen.
In the garden, strawberries benefit from the shade provided by rhubarb's broad leaves, which helps keep their roots cool.
In return, strawberries, with their ground-hugging nature, act as a living mulch for rhubarb, conserving moisture and suppressing weeds.
Here are the strawberries I recommend growing:
Beans and Garlic
A less obvious but equally beneficial pairing involves beans and garlic.
Beans, as legumes, have a unique ability to fix nitrogen in the soil, a nutrient that rhubarb relishes.
Garlic, on the other hand, repels several pests and can keep potential threats to rhubarb at bay.
Here are the beans I recommend planting:
Herbs
The world of herbs offers several allies for rhubarb.
Catnip, for example, with its fragrant leaves, attracts pollinators and deters certain pests, ensuring that your garden remains a lively but protected space.
Additionally, some herbs can improve soil quality, ensuring rhubarb has a rich base to thrive upon.
Here are the catnip seeds I recommend planting:
Cucumbers
These refreshing vegetables can benefit from the shade provided by rhubarb on hot summer days.
The shade ensures cucumbers remain hydrated and less prone to stress, leading to a crunchy and juicy harvest.

Plants to Avoid Near Rhubarb
Just as some plants thrive alongside rhubarb, others might not fare as well in its vicinity.
These interactions, stemming from nature's complex web of relationships, can be due to various factors ranging from competition for nutrients to chemical incompatibilities.
Understanding which plants to keep at a distance from your rhubarb patch can make a significant difference in the overall health and productivity of your garden.
Brassica Family
While members of the Brassica family, like broccoli, cauliflower, and cabbage, are staples in many gardens, they don't typically make good neighbors for rhubarb.
The reason remains a subject of debate among gardeners, but some speculate it's due to competition for nutrients or potential soil pH clashes.
Potatoes
The world of companion planting is filled with age-old wisdom, some of which warns against planting rhubarb near potatoes.
While the exact reasons aren't scientifically established, it's believed that both plants might compete for similar soil nutrients, leading to suboptimal growth for both.

Black Walnut
This tree is known for producing juglone, a chemical that can inhibit the growth of many plants, rhubarb included.
If you have black walnut trees on your property, it's best to ensure your rhubarb patch is planted at a considerable distance to avoid the harmful effects of this natural herbicide.
Tomatoes
Another surprising entry in the list of rhubarb's unfriendly neighbors is the tomato plant.
Both plants, being heavy feeders, could compete for nutrients, especially if the soil isn't adequately enriched.
Moreover, rhubarb leaves, which are toxic, might pose a risk if they come into contact with tomato fruits.
Ensuring that rhubarb is planted with care, away from these potentially conflicting neighbors, can lead to a healthier, more productive garden.
While companion planting offers invaluable insights, it's also essential to observe your garden's unique dynamics and adjust based on the specific needs and responses of your plants.
