Knockout roses are a popular choice for gardeners due to their long blooming season, low maintenance, and disease-resistant nature. However, deciding what to plant in front of knockout roses.
Choosing the right plants to complement knockout roses can enhance the beauty of your garden and provide additional benefits such as pest control and fragrance.
Understanding the growth habits of knockout roses is essential when selecting companion plants. These roses typically grow to be three to four feet tall and wide, so plants that are shorter and have a mounding or trailing habit work well in front of them.
Additionally, choosing plants with similar sun, water, and soil requirements can help ensure their success.
Benefits of companion planting with knockout roses include attracting beneficial insects, deterring pests, and adding aesthetic value to your garden. Lavender, for example, not only complements the color of knockout roses but also helps repel rabbits and deer while attracting pollinators.

Understanding Knockout Roses
Knockout roses are a popular choice for gardeners due to their hardiness and low maintenance requirements. These shrubs are disease-resistant and can withstand harsh weather conditions, making them a great option for those who want to add color to their garden without having to put in too much effort.
One of the most common diseases that affect roses is black spot disease. However, Knockout roses are resistant to this disease, which means that they require less care than other varieties. They are also resistant to powdery mildew, another common disease that affects roses.
Knockout roses are hardy and can tolerate a wide range of soil types. They prefer well-drained soil that is moist but not waterlogged. They also require a pH level of 6.0 to 7.0, which is slightly acidic. It is important to ensure that the soil is not too alkaline, as this can cause nutrient deficiencies.
When planting Knockout roses, it is important to consider their sunlight requirements. They require full sun to grow and thrive, so it is important to choose a location that receives at least 6 hours of direct sunlight per day. They also require good air circulation, which helps to prevent disease.
Water is also important for the health of Knockout roses. They require regular watering, especially during the first year after planting. It is important to ensure that the soil is moist but not waterlogged. Moisture-retentive soil is ideal for Knockout roses, as it helps to keep the roots hydrated.
Benefits of Companion Planting
Companion planting is the practice of planting different species of plants together to achieve mutual benefits. In the case of Knockout roses, companion planting can help deter pests, attract pollinators, and attract beneficial insects to the garden.
One of the most significant benefits of companion planting is pest control. Certain companion plants, such as marigolds and alliums, emit strong odors that repel pests like aphids, Japanese beetles, and spider mites.
By planting these plants alongside Knockout roses, gardeners can reduce the need for chemical pesticides and create a more natural, sustainable garden.
Another benefit of companion planting with Knockout roses is the ability to attract pollinators. Bees, butterflies, and other pollinators are essential for the health and success of a flower garden. Companion plants like lavender, alyssum, and verbenas are known to attract pollinators, which can help increase the yield and quality of Knockout rose blooms.
Companion planting can also attract beneficial insects to the garden. Ladybugs, lacewings, and other beneficial insects feed on pests like aphids and spider mites, helping to keep the garden healthy and balanced.
By planting companion plants like parsley, dill, and fennel, gardeners can attract these beneficial insects to the garden and reduce the need for chemical pesticides.
Choosing the Right Plants
When choosing plants to plant in front of knockout roses, it is important to consider a few factors. First, the plants should complement the blooms of the roses. For example, red knockout roses can be paired with white, pink, or yellow blooms.
Lavender is also a great option as it complements the color of the roses and helps deter rabbits and deer while attracting pollinators.
Second, the plants should be able to thrive in the same growing conditions as the roses. Knockout roses thrive in well-draining soil and can tolerate a bit of drought, so plants that also prefer these conditions would be a good choice.
Boxwood, Shasta daisies, marigolds, alliums, and lavandula are all perennials that can thrive in the same growing conditions as knockout roses.
Third, the plants should be able to provide year-round interest. Sage, lilies, verbena, and fuchsias are all great options as they provide colorful blooms throughout the growing season. Germander and Mexican blue sage are great options for adding texture and interest to the garden.
Fourth, the plants should be able to help protect the roses from harmful pests and nematodes. Alyssum, foxgloves, snapdragons, hosta, and catmint are all great companion plants for roses as they attract beneficial insects that can help control pests.
Finally, the plants should be able to complement the overall design and style of the garden. Lantana and geraniums are great options for adding pops of color and texture to the garden.
Planting in Different Locations
When it comes to planting in front of knockout roses, the location matters. Different locations require different types of plants. Here are some suggestions for planting in different locations:
1. Border Plant
For a border plant, consider planting low-growing plants like marigolds or snapdragons. These plants will complement the knockout roses and create a beautiful border.
If you are planting in a hedge, consider planting taller plants like boxwood or yew. These plants will create a beautiful hedge that will complement the knockout roses.
If you are planting in containers, consider planting low-growing plants like petunias or impatiens. These plants will complement the knockout roses and create a beautiful container garden.
4. Ground Cover
For ground cover, consider planting low-growing plants like creeping phlox or creeping thyme. These plants will create a beautiful ground cover that will complement the knockout roses.
5. Mass Planting
For mass planting, consider planting low-growing plants like dianthus or verbena. These plants will create a beautiful mass planting that will complement the knockout roses.
6. Driveway or Pathway
If you are planting near a driveway or pathway, consider planting low-growing plants like alyssum or lobelia. These plants will create a beautiful border that will complement the knockout roses.
7. Foundation Plantings
For foundation plantings, consider planting taller plants like hydrangeas or azaleas. These plants will create a beautiful foundation planting that will complement the knockout roses.
8. Perennial Beds or Rose Gardens
If you are planting in a perennial bed or rose garden, consider planting low-growing plants like salvia or coreopsis. These plants will create a beautiful perennial bed or rose garden that will complement the knockout roses.
8. Front Door
For planting near the front door, consider planting low-growing plants like pansies or violas. These plants will create a beautiful border that will complement the knockout roses.
Maintaining Your Garden
To keep your garden looking its best, it’s important to maintain it properly. This includes watering, pruning, and feeding your plants regularly.
Watering is especially important for knockout roses, as they prefer well-drained soil that is kept consistently moist. Be careful not to overwater, as this can lead to root rot and other problems. A good rule of thumb is to water deeply once or twice a week, depending on the weather and soil conditions.
Pruning is another important aspect of maintaining your garden. Knockout roses should be pruned in late winter or early spring, before new growth begins. This helps to promote healthy growth and flowering throughout the season.
Pruning practices may vary depending on the type of rose and its growth habits, so be sure to do your research and follow best practices. Feeding your plants is also important to keep them healthy and thriving.
Knockout roses are relatively low-maintenance and don’t require a lot of fertilizer, but it’s still a good idea to give them some extra nutrients throughout the growing season. A slow-release fertilizer can be applied in early spring and again in mid-summer to keep your roses looking their best.
In addition to these basic maintenance tasks, there are a number of resources available to help you care for your garden. Local garden centers and nurseries can provide expert advice on everything from soil preparation to pest control. Online resources and gardening forums can also be a great source of information and inspiration.
Dealing with Pests and Diseases
Knockout roses are hardy plants that are resistant to most pests and diseases. However, there are a few common issues that gardeners might encounter when growing these roses. Here are some tips on how to deal with pests and diseases that might affect your knockout roses:
Some common pests that might affect your knockout roses include aphids, spider mites, and Japanese beetles. Here are some ways to deal with these pests:
- Aphids: These small, soft-bodied insects can be removed by spraying your roses with a strong stream of water or by using insecticidal soap.

2. Rabbits and Deer
Rabbits and deer can be a problem for gardeners who are growing knockout roses. Here are some ways to deter these animals:

- Deer: Deer can be deterred by planting garlic or onions near your roses. These plants have a strong smell that deer find unpleasant.
Knockout roses are susceptible to a few common diseases, including black spot and powdery mildew. Here are some ways to deal with these diseases:
- Black spot: This fungal disease can be prevented by planting your roses in a location with good air circulation and by watering them at the base of the plant rather than from above. If your roses do get black spot, you can treat them with a fungicide.
- Powdery mildew: This fungal disease can be prevented by planting your roses in a location with good air circulation and by watering them at the base of the plant rather than from above. If your roses do get powdery mildew, you can treat them with a fungicide.
By following these tips, you can keep your knockout roses healthy and free from pests and diseases.
Adding Aesthetic Value
In addition to their stunning beauty, Knock Out roses can be enhanced by planting suitable companion plants that add to their aesthetic value. By carefully selecting the right plants, gardeners can create a harmonious and visually appealing landscape that also provides a range of benefits to the roses.
One way to add aesthetic value is by planting low hedges in front of the roses. These hedges can serve as a natural border that defines the space and adds structure to the garden. Boxwood, for example, is a popular choice for low hedges due to its versatility and ability to be shaped into various forms.
Another way to enhance the aesthetic value of Knock Out roses is by using filler plants. These plants fill in the gaps between the roses and create a cohesive look. Some great options for filler plants include lavender, creeping thyme, and daylilies. These plants not only add visual appeal but also complement the roses’ fragrance and scent.
For those who want to add fragrance to their garden, fragrant border plants like lavender and rosemary can be planted alongside the roses. These plants not only add a pleasing scent but also deter pests and attract beneficial insects.
Knock Out roses are versatile and can be used in a variety of garden styles, including cottage gardens. To create a cottage garden feel, gardeners can plant companion plants like daisies, coneflowers, and black-eyed Susans. These plants not only add to the overall aesthetic but also attract pollinators like bees and butterflies.
Choosing Plants for Specific Purposes
When it comes to choosing plants to pair with Knockout roses, it’s important to consider the specific purposes you want the plants to serve. Here are some examples of plants that can serve specific purposes:
1. Deter Pests
Some plants can help deter pests that may damage your Knockout roses. Creeping thyme (Thymus serpyllum) is an excellent choice for ground cover in front of or around your rose bushes. It not only adds a beautiful touch to your garden but also acts as a natural pest repellent by deterring Japanese beetles, aphids, and other pests.
2. Attract Pollinators
If you want to attract pollinators to your garden, consider planting Verbena or Tagetes. Verbena is a beautiful, low-maintenance plant that produces clusters of small flowers in shades of purple, pink, and white.
It is a great choice for attracting butterflies and bees to your garden. Tagetes, also known as marigolds, are easy to grow and produce bright, colorful flowers that attract bees and other pollinators.
3. Drought Tolerant
If you live in an area with hot, dry summers, you may want to consider planting drought-tolerant plants alongside your Knockout roses. Hydrangeas are an excellent choice for this purpose. They are hardy, low-maintenance plants that thrive in direct sunlight and can handle periods of drought.
4. Adding Color and Texture
If you want to add some color and texture to your garden, consider planting Verbenas. They come in a variety of colors, including pink, purple, red, and white, and produce beautiful, delicate flowers that add a touch of elegance to any garden. They are also low-maintenance and easy to grow, making them a great choice for novice gardeners.
There are many options for planting in front of Knockout roses to enhance their beauty and create an aesthetically pleasing garden.
Consider planting low-growing plants such as creeping phlox, sweet alyssum, or dwarf iris in front of the roses to provide a colorful ground cover. These plants will not compete with the roses for nutrients and will create a beautiful contrast against the taller roses.
If you want to add some height to your garden, try planting ornamental grasses or taller perennials such as coneflowers, black-eyed susans, or salvia. These plants will add a vertical element to your garden and provide a beautiful backdrop for your roses.
Another option is to plant companion plants that have similar growing requirements as Knockout roses. For example, lavender, marigolds, geraniums, zinnias, and impatiens all grow well with roses and can provide additional color and interest to your garden.
