Creating a native garden in Zone 7 offers many benefits, including attracting local pollinators and supporting native wildlife. However, managing pests naturally is essential to maintaining a healthy garden. One effective strategy is companion planting, which involves planting certain species together to deter pests and promote plant health.
Understanding Companion Planting
Companion planting is an age-old practice that uses the natural relationships between plants to reduce pest problems. Some plants repel pests, while others attract beneficial insects that prey on harmful pests. In Zone 7 native gardens, selecting the right companions can enhance plant resilience and reduce the need for chemical pest control.
Native Plants and Pest Prevention
Zone 7 features a diverse range of native plants, including:
- Black-eyed Susan (Rudbeckia hirta)
- Purple Coneflower (Echinacea purpurea)
- Goldenrod (Solidago spp.)
- Switchgrass (Panicum virgatum)
- Little Bluestem (Schizachyrium scoparium)
These plants can be paired with specific companions to naturally deter pests. For example, planting aromatic herbs near native flowers can repel unwanted insects.
Effective Companion Plants for Pest Control
Some of the best companion plants for native Zone 7 gardens include:
- Marigolds: Repel nematodes and aphids.
- Yarrow: Attracts beneficial insects like ladybugs and predatory wasps.
- Goldenrod: Supports pollinators and discourages pest buildup.
- Sunflowers: Draw pests away from other plants and attract beneficial insects.
- Alliums (garlic, onions): Repel aphids, beetles, and other pests.
Planting Tips for Success
To maximize pest prevention through companion planting:
- Mix aromatic herbs like basil, thyme, and oregano with native plants.
- Plant pest-repelling species along garden borders.
- Ensure proper spacing to allow air circulation and reduce disease risk.
- Introduce flowering plants that attract beneficial insects early in the season.
Additional Strategies for a Healthy Native Garden
Companion planting is most effective when combined with other natural pest control methods, such as:
- Encouraging native predators like ladybugs and lacewings.
- Maintaining healthy soil through composting and mulching.
- Removing pest-infested plants promptly.
- Using physical barriers like row covers when necessary.
By integrating companion planting with these practices, gardeners can create resilient, pest-resistant native gardens in Zone 7 that support local ecosystems and reduce chemical use.
