Plants to Avoid in Your Rose Garden
While companion planting can offer numerous benefits to your roses, not all plants make good neighbors.
Here are some plants you might want to think twice about before introducing them to your rose garden.
Grasses
Grasses immediately adjacent to rose beds, can be problematic as companions. Grasses compete aggressively for water, nutrients, and light, which can stress roses and reduce their vigor.
Additionally, lawnmowers and trimmers used around roses can accidentally damage the plants.
Thinking about removing grass from your garden? Check out my guide How to Remove Grass to Start a Garden.
Vegetables and Herbs with Heavy Water Needs
While some herbs and vegetables can be beneficial to roses, those requiring a lot of water may not be suitable companions.
Plants like cucumbers, melons, and squash demand significant moisture, which can lead to overwatering issues for roses, potentially causing root rot or fungal diseases.
To learn more about growing squash, check out my guide Growing Pumpkins in Containers: A Complete Urban Garden Guide.
Large Shrubs and Trees
Large shrubs and trees can compete with roses for sunlight, water, and nutrients. Their extensive root systems can overpower the comparatively less aggressive roots of rose bushes, hindering their growth and bloom production.
Consider growing shrubs in containers, check out my guide Top Low Maintenance Evergreen Plants for Pots.
Mint
While mint has many benefits its aggressive growth habit makes it a poor companion for roses.
Mint can quickly overrun a garden bed, competing with roses for space, light, and nutrients. If you want to include mint in your garden, consider planting it in containers to keep it contained.

Why Companion Planting?
Companion planting is a big part of sustainable gardening, offering a multifaceted approach to cultivating healthier plants and more vibrant gardens.
When it comes to roses, companion planting isn't just about beauty; it's a strategic method that can enhance the overall health and productivity of your garden.
Here’s why:
Natural Pest Control
One of the primary benefits of companion planting is its role in natural pest management. Certain plants can repel common rose pests such as aphids, Japanese beetles, and spider mites.
For example, the strong fragrances of herbs like lavender can deter pests, reducing the need for chemical insecticides.
Disease Prevention
Diseases like black spot and powdery mildew are less likely to spread in well-aerated gardens where air circulation is promoted by the strategic placement of companion plants.
Additionally, some companions can improve soil health and moisture levels, creating less favorable conditions for fungal diseases.
Enhanced Pollination
Including plants that attract pollinators can significantly increase your garden's productivity.
Bees, butterflies, and other beneficial insects are drawn to companion plants like bee balm and salvia, which in turn helps to pollinate your roses, leading to better bloom production.
Improved Growing Conditions
Certain companion plants can improve growing conditions for roses by enriching the soil, providing shade or support, and even enhancing nutrient uptake.
For instance, plants from the onion family can deter pests and improve soil quality, while tall companions can offer some shade during the hottest parts of the day, preventing sun scorch.
Biodiversity
A diverse garden ecosystem is more resilient and less susceptible to outbreaks of pests and diseases.
Companion planting introduces a variety of plants that support different insects and microbial life, contributing to a balanced garden ecosystem.
Aesthetic Harmony
Beyond the practical benefits, companion planting allows for creative expression in the garden.
By combining roses with a variety of textures, colors, and heights, you can achieve stunning visual displays that change throughout the seasons.
Space Optimization
Especially relevant for small gardens or those with limited planting area, companion planting makes efficient use of space.
Underplanting roses with low-growing companions can maximize garden productivity and beauty without requiring additional square footage.
Companion Planting Tips
1. Understand the Needs of Your Plants
Before introducing companion plants to your rose garden, it's crucial to understand the specific needs of each plant.
This includes sunlight requirements, water needs, soil type preferences, and growth habits. Roses, for instance, generally prefer full sun, well-draining soil, and regular watering.
Your companion plants should thrive under similar conditions to ensure they don't compete with roses but rather complement their growth.
2. Consider Bloom Times and Colors
To achieve a visually appealing garden throughout the growing season, select companion plants with staggered bloom times.
This ensures that at any given point in the season, your garden will have splashes of color and interest.
Additionally, consider the color palette of your roses and companion plants to create harmonious or contrasting combinations that enhance the beauty of your garden.
3. Plan for Height and Spacing
Proper spacing is essential to prevent overcrowding and ensure each plant receives adequate light, air, and nutrients.
Taller companions should be placed behind or around the roses to provide a backdrop without overshadowing them.
Lower-growing companions can be planted in front or as ground cover to suppress weeds and maintain soil moisture.
4. Promote Biodiversity
Diversity in plant species not only contributes to a garden's aesthetic appeal but also supports a healthier ecosystem.
A mix of companion plants can attract a variety of beneficial insects, deter pests, and reduce the risk of disease.
Incorporate a range of perennials, annuals, herbs, and even small shrubs to create a dynamic and resilient garden environment.
5. Soil Health and Mulching
Companion plants can contribute to the overall health of the soil in your rose garden. Additionally, using organic mulch around your roses and companions can help retain soil moisture, suppress weeds, and gradually improve soil structure and fertility.
To learn more, check out my guide The Best Alternatives to Traditional Mulch for Your Garden.
6. Watering Considerations
While roses and their companions may have similar water needs, it's important to implement a watering regime that meets the specific needs of each plant type.
Use drip irrigation or soaker hoses to deliver water directly to the root zone, minimizing leaf wetness and reducing the risk of disease.
Here is the soaker hose I recommend:
7. Rotate Companions
Just as with vegetable gardening, rotating companion plants from year to year can help prevent soil depletion and reduce the buildup of pests and diseases.
Experiment with different companion plants to see which combinations work best with your roses and garden conditions.
FAQs
Can companion planting really help prevent diseases like black spot?
Yes, companion planting can play a significant role in disease prevention, including the dreaded black spot on roses.
Plants such as garlic, and other members of the onion family have been noted for their ability to deter various pests and possibly reduce fungal infections due to their natural antifungal properties.
These companions can help improve air circulation around the rose bushes and may have compounds in their roots or foliage that suppress or repel disease-causing agents.
However, it's important to maintain good garden hygiene and practice proper spacing and watering to maximize these benefits.
What should I plant with roses to deter aphids?
Plants that are known to repel aphids include marigolds, garlic, and lavender. These plants can emit scents or substances that are unappealing to aphids, helping to keep them away from your roses.
Furthermore, planting flowers like calendula and sweet alyssum can attract beneficial insects such as ladybugs and lacewings, which are natural predators of aphids.
Incorporating these plants into your rose garden can help create a more balanced ecosystem, reducing aphid populations naturally.
Are there companion plants that should be avoided around roses?
Yes, it's wise to avoid planting certain species too close to roses due to competition for resources or increased risk of disease.
For example, plants that have heavy water or nutrient needs may compete with roses, potentially stressing the plants and leading to poor growth or bloom.
Vegetables that are prone to the same pests and diseases as roses, such as tomatoes (which can share blight with roses), should also be planted with caution.
It's beneficial to keep roses away from large trees and shrubs that can overshadow them and aggressively compete for water and nutrients.
How do I choose companion plants for my rose variety?
Choosing companion plants for your roses involves considering several factors, including the specific needs and characteristics of your rose variety.
For example, if you have climbing roses, you might select companions that can fill in the lower space without competing aggressively for resources.
For shrub roses, consider perennials that match or complement their height and spread. Always take into account the sunlight, soil, and water requirements of both your roses and the potential companions to ensure they are compatible.
Can I use companion planting in pots?
Absolutely! Companion planting can be effectively utilized in container gardens. Choose companions that have similar pot size and care requirements as your potted roses.
Low-growing herbs, annuals, or perennials can complement miniature or patio roses beautifully in pots.
Ensure that the companion plants do not overtake the rose in terms of growth, and pay careful attention to watering, as container plants typically require more frequent irrigation.
This approach can add visual interest and provide the same benefits as in-ground companion planting, such as pest deterrence and increased biodiversity.
