Hollyhocks are beautiful and tall garden plants that can add charm to any landscape. However, they are often vulnerable to pests such as aphids, Japanese beetles, and spider mites. Using companion plants is an effective, natural way to protect hollyhocks without relying on chemical pesticides. This article explores how to select and plant companion species to defend hollyhocks against common pests.
Understanding Hollyhock Pests
Hollyhocks attract several pests that can damage their leaves and flowers. The most common pests include:
- Aphids
- Japanese beetles
- Spider mites
- Flea beetles
These pests can weaken the plants, reduce flowering, and even cause plant death if not managed properly. Introducing certain companion plants can help repel or distract pests, promoting healthier hollyhocks.
Best Companion Plants for Hollyhocks
Choosing the right companion plants involves selecting species that naturally repel pests or attract beneficial insects. Here are some of the most effective companions for hollyhocks:

- Lavender: Its strong fragrance deters many insects, including beetles and moths.
- Catnip: Attracts beneficial insects like predatory wasps that prey on pests.
- Salvia: Provides a habitat for pollinators and repels unwanted insects.
- Chives and Garlic: Their strong smell can deter aphids and beetles.
Planting and Maintenance Tips
To maximize the effectiveness of companion planting, follow these tips:
- Plant companion species close to hollyhocks, ensuring they have enough space to grow.
