Companion Planting for Roses: Nature's Pest Control and Design

True companion planting goes beyond "what looks pretty together." It builds a balanced ecosystem where plants, insects, and birds collaborate to suppress pests and diseases naturally.

Plants That Recruit Beneficials

For hummingbirds & pollinators: Agastache, Nicotiana, Salvia, Monarda (Diane's Seeds research)
To repel Japanese beetles & borers: Tansy, Rue, Garlic (Alabama Extension)
To repel aphids: Feverfew, Alliums (onions, chives, garlic)
To deter rose beetles: Parsley
For nematode suppression: Marigolds (multi-season)
Alliums also reduce black spot, mildew, spider mites (Texas Garden Toad)

Design & Root Compatibility

Santa Barbara Rose Society emphasizes non-competing root zones: Alstroemeria, Dianthus, and Dahlias coexist well and help control spider mites. Avoid planting companions that crowd rose feeder roots, which regenerate each spring.
