Rose Companion Plants and Their Benefits for Your Roses

1. Lavender

Lavender is a popular herbaceous plant that is well-suited as a companion for roses. The fragrant lavender releases calming oils into the soil that act as a natural deterrent against many common rose pests such as insects and rabbits. Research has also shown roses planted near lavender tend to exhibit improved hardiness and vigor with less need for pesticide applications.

The pest-repelling properties of lavender come from its extensive root system, which spreads the oils below the surface. Gardeners have found lavender to be an effective companion, helping to protect nearby roses without the rose bushes suffering any ill effects themselves.

Its calming scent is also enjoyed by many rose-lovers. With some strategic planting of lavender between rose bushes each spring, a gardener can take advantage of these companion-plant benefits all through the growing season.

2. Catmint

Like its cousin lavender, catmint (Nepeta cataria) is appreciated by gardeners for its pest-repelling properties and ornamental value when paired with roses. The fuzzy gray-green leaves and whorls of pink or blue flowers emit a scent that repels many insect pests that may otherwise damage rose blossoms.

Similar to lavender, catmint spreads these natural oils through an extensive root system underground. When planted adjacent to or intermixed with roses, catmint helps protect the vulnerable rose bushes from harm without the need for chemical pest control applications. At the same time, the eye-catching catmint adds visual interest and diversity to the rose garden.

Its ornamental attributes pair well with a variety of rose colors and varieties commonly grown. Both casual and experienced rose growers have found strategic use of catmint to benefit plant health and reduce pest concerns season after season.

3. Garlic

Garlic is a popular plant that provides numerous benefits as a companion for roses. While most gardeners grow garlic for use in cooking, its strong scent also deters many common pests that target roses.

When planted around the edges of rose beds, garlic emits a powerful odor from its below-ground bulbs that helps repel soft-bodied insects and other small herbivores that may attempt to feed on delicate rose blooms or foliage. In addition to its pest-repelling characteristics, garlic also acts as a nutrient powerhouse when grown amongst roses.

Its bulbs enrich the surrounding soil with minerals and vitamins extracted from the earth. With regular watering and sunlight, garlic circulates these beneficial nutrients through its leaves and bulb, improving the overall health and vigor of nearby roses for enhanced flower and hip production. Perhaps best of all, a border of garlic deters pests naturally without any need for chemical sprays or powders around valuable rose bushes.

With minimal effort, gardeners can incorporate this multi-purpose allium to help strengthen their roses’ defenses against common insect and mammal pests. While many organic remedies require repeated applications, garlic offers seasonal-long protection through its roots and leaves underground and at soil level. Its stench safely shields vulnerable blooms and foliage without being reapplied like synthetic pest controls.

Though not always aesthetically pleasing, a strategically placed perimeter of garlic bulbs keeps roses beautiful from the inside out with healthy green leaves and bountiful fragrant flowers. Many rose gardeners find garlic to be an indispensable long-term investment for biological pest management where traditional poisonous chemicals are unwanted.

4. Chives

The subtle yet aromatic chive is a versatile plant that pairs well with roses as both an ornamental edging and pest deterrent.
