Bamboo is one of the most unique and versatile plants found in gardens and landscapes around the world. Known for its fast growth rate and hardy nature, bamboo can provide numerous benefits like erosion control, habitat for wildlife, and versatile landscaping options.
However, bamboo is not meant to grow alone and thrives best when companion planted with other beneficial plants. Companion planting with bamboo can improve soil health, enhance pest management, provide essential nutrients, and create balanced, low maintenance ecosystems.
Companion Plants for Bamboo
This article will explore the many benefits of companion planting with bamboo and provide recommendations on the best plants to pair with different bamboo species in small and large spaces.
We’ll look at nitrogen fixing legumes, nutrient rich plants, pest repelling companions, erosion controllers, and more. The goal is to understand how to design functional bamboo ecosystems that provide value while requiring minimal inputs.
- Companion planting can improve soil health, increase biodiversity, and provide better pest management for bamboo
- Choose companions based on bamboo’s growing conditions and complementary growth habits
- Legumes, like clover, fix nitrogen to nourish bamboo and other plants
- Nutrient rich plants like comfrey add phosphorus, potassium and trace minerals
- Carefully selected companions can help control pesky insects and reduce pesticide use
- Erosion preventing groundcovers stabilize soil to protect bamboo
- Compact options allow thriving bamboo ecosystems even in small gardens
Benefits of Companion Planting with Bamboo
When planted with the right companions, bamboo gardens can become productive, low maintenance ecosystems. Some key benefits of companion planting with bamboo include:
Improved Soil Health
Different plants affect the soil in various ways. Legumes fix nitrogen, some plants mine deep nutrients, while others produce compounds that stimulate microbial activity.
When grown together, these soil enhancing properties have a multiplied effect. The diverse root systems of companion plants also create channels that improve drainage, aeration, and nutrient absorption around bamboo’s roots.
Monocultures of single plant species are vulnerable to pests and disease. But Polycultures with diverse plantings confuse pests and provide habitat for beneficial insects. They also support wildlife by providing food and shelter. This biodiversity strengthens ecosystems and makes them more resilient to threats.
Enhanced Ecosystem Services
Beyond individual benefits, intentionally selected companions work synergistically to recycle nutrients, suppress weeds, and create microclimates.
Soil fertility improves over time, reducing the need for external inputs. Water retains better in the soil, moderating moisture levels. Companions essentially amplify bamboo’s ecosystem services.
Better Pest Management
strategically placed companion plants like alliums, certain flowers, and herbs can effectively repel or attract beneficial insects to control major bamboo pests. Others may distract pests from bamboo or act as a barrier. When used thoughtfully, such biocontrols minimize pest damage without relying on pesticides.
As we can see, the advantages of companion planting go well beyond aesthetics. By pairing bamboo with plants tailored for the site conditions and overall goals, gardens become productive systems that sustain themselves with minimal maintenance. Let’s explore suitable plant partners for different bamboo needs and growing areas.
Choosing the Right Companion Plants for Bamboo
When selecting companion plants, the first step is to understand the bamboo species in question and its preferred growing conditions. Bamboos vary significantly in terms of size, spreading behavior, pH and moisture preferences. Planting companions also need to complement bamboo’s growing habits rather than compete directly with them for space, light and nutrients.
Diversity is also important the more varieties included, the greater the ecological benefits. However, gardens still need to remain aesthetically cohesive. A balanced mix of trees, shrubs, groundcovers and flowers creates vertical layers for wildlife and visual interest.
Some general principles for choosing companion plants include:
- Nitrogen fixing plants for fostering soil fertility
- Nutrient accumulators that tap hard to reach minerals
- Edibles, medicinals or ornamentals that attract beneficial insects
- Deeprooted options for maximum water and nutrient absorption
- Erosion preventers along slopes or areas prone to runoff
- Plants with varying pH, water and light preferences
- Locally native or climate adapted species over exotic varieties
Let’s explore in more detail some key families and species that make excellent bamboo companions.
Nitrogen Fixing Legumes
Legumes, characterized by their unique ability to fix nitrogen from the air, are extremely beneficial for bamboo gardens. They do this through a symbiotic relationship with rhizobia bacteria in nodules on their roots. This biological nitrogen fixation enriches the soil without external fertilizers.
Some top legume choices for bamboo include:
|White clover||Spreading rapidly via stolons to form a dense groundcover, nitrogen fixing flowers attract pollinators.|
|Crimson clover||Annual option that brings quick green manure benefits before summer heat, bright blooms for pollinators.|
|Fava bean||Tall climbers produce huge leaves to shade soil, edible beans high in nutrients.|
|Peas||Rapid cover crop for nitrogen fixation and soil protection over winter months.|
|Alfalfa||Deep taproots access subsoil nutrients and moisture, excellent companion for erosion control.|
The nitrogen fixed by legumes nourishes not only the legumes themselves but also companion plants like bamboo. This biological nitrogen pumping improves soil health and fertility over time while reducing the need for fertilizing. Legumes also prevent erosion, compete against weeds, and provide habitat and forage.
Other Nutrient Rich Companion Plants for Bamboo
Beyond nitrogen, bamboo also requires ample phosphorus, potassium, calcium and trace minerals for optimal growth. Certain plants have evolved to uptake nutrients that are otherwise unavailable to most plants. When grown together, these nutrient accumulators cycle minerals through decomposition to nourish whole gardens.
Some top options here:
|Comfrey||Potassium, phosphorus, magnesium, calcium, vitamins/minerals|
|Nettles||Nitrogen, potassium, calcium, magnesium, iron|
|Yarrow||Calcium, silicon, zinc, iron|
|Plantain||Calcium, copper, potassium, vitamins|
As dynamic accumulators, plants like comfrey and nettles scavenge minerals through their extensive root systems, even remediating contaminated soils. Their quick decomposition through mulching or composting releases these concentrated nutrients to nourish other plants. Not only do they improve soil structure and fertility, their flowers also attract beneficial insects to bamboo gardens.
Plants for Pest Control
While companion planting creates balanced bamboo ecosystems with fewer pest issues overall, certain pests will inevitably occur at some point. Carefully selected companions can help naturally ward off or control key bamboo pests such as:
- Scale insects
Some top pest repelling plant options include:
|Plant||Pest Control Mechanism|
|Garlic||Repels many insect pests through natural oils.|
|Marigolds||Release chemicals that interfere with pest development.|
|Mint||Produces strong scent masking bamboo from pests.|
|Cilantro||Masks bamboo scent, shelters beneficial insects.|
|Dill||Attracts predatory wasps and flies that parasitize pests.|
Additionally, flowering plants provide food sources for predatory and parasitic insects like ladybugs, lacewings, and hoverflies that actively hunt pests.
Careful spacing of such companions deters pests from bamboo without using pesticides. Their aromatic oils, scents and exudates safely repel major bamboo attacking insects.
Companion Plants for Erosion Control
Erosion poises a constant threat to bamboo, especially on slopes or areas exposed to heavy rain or runoff. Deep rooted grass like plants bind soil effectively and prevent nutrient loss. Some top erosion controllers for bamboo include:
|Plant||Root Depth||Growth Habit|
|Alfalfa||Over 10 feet||Deep roots create channels improving drainage & stability.|
|Bamboo||Several feet or more||Thick rhizomes anchor soil structure.|
|Purple prairie clover||2-4 feet||Forms dense mats spreading horizontally.|
|Fescue||2-3 feet||Fibrous clumping roots hold soil together.|
|Japanese sedge||2-3 feet||Fast growth forms an impervious ground cover layer.|
Paired with deep rooted trees and shrubs, these tough grasses and grass like plants protect vulnerable areas and preserve soil productivity long term. Their extensive fibrous root systems retain moisture, improve soil aggregation, and physically hold soil in place during rains. This stabilizes slopes for bamboo to thrive with minimal risk of erosion.
Companion Plants for Bamboo: for Small Spaces
For gardeners with limited space, bamboo is still an attainable option when paired with compact companion plants suited to containers or tight spots. Some top bamboo species ideal for small gardens include dwarf bamboo varieties as well as clumping bamboo.
Container gardens allow creative vertical stacking with trailing plants dangling over the edges. Some top compact bamboo companions include:
|Dwarf honeywort||Forms a 6 inch carpet of silver foliage perfect for spilling over containers.|
|Dwarf Asian jasmine||Fragrant star shaped flowers on a vigorously trailing vine perfect for hanging baskets.|
|Dwarf herb selection||Pair basil, rosemary, thyme, oregano and more for culinary and pest benefits in a compact space.|
|Dwarf butterfly bush||Attracts pollinators with funnel shaped blooms on a 2-3 foot tall shrub.|
|Dwarf azalea||Dense clusters of colorful flowers on an evergreen 3-4 foot tall, wide shrub.|
For small in ground plots, wind dwarf clumping bamboos with low growing groundcovers, creeping herbs and bulbs. Dwarf legumes fix nutrients without taking over. Emphasis should be on multilevel plantings, vertical training and maximizing space efficiently with limited plant choices. Creative container stacking mimics the structure and function of bigger bamboo ecosystems.
Companion Plants for Bamboo: for Large Spaces
In expansive gardens, bamboo truly shines when given appropriate companions to meet its scale. There is space for larger trees, shrubs and ground layers. Here are some top options for bamboo in big landscapes:
|Maple trees||60-100 feet||Provide autumn color, shade bamboo; extensive roots nourish soil.|
|Golden rain tree||60-80 feet||Attractive foliage, peelings add organic matter as mulch.|
|Hydrangea||3-10 feet||Summer flowers, holds moisture; leaves add minerals when composted.|
|Blazing star||3-5 feet||Fall bloom attracts pollinators; branching structure creates varied layers.|
|Hosta||1-3 feet||Ornamental leaves provide shade, harbors beneficial insects.|
|Switchgrass||3-6 feet||Ornamental plumes, erosion control & deep roots improve structure.|
Larger trees and structure plants foster biodiversity with habitat and forage. Their leaf drop and decomposition in autumn nourishes bamboo. Varied layers meet different needs for microclimates, food, nesting places and wind protection. Expansive bamboo forests become rich ecosystems.
