By selecting specific companion plants, gardeners can attract beneficial insects that help control pests and improve overall plant health. In this article, we will explore some companion plants that can be used to attract beneficial insects in raised beds.
1. Marigolds
Marigolds are well-known for repelling a wide range of pests including aphids, whiteflies, and nematodes. These vibrant flowers have a pungent scent that many insects find repulsive. Additionally, marigolds attract ladybugs and parasitic wasps, both of which are beneficial insects that feed on common garden pests.
2. Nasturtiums
Nasturtiums are not only visually appealing but also attract a variety of beneficial insects. They attract predatory insects like hoverflies and ladybugs, which help control aphid populations. Nasturtiums also repel squash bugs, beetles, and whiteflies. Planting nasturtiums around your raised bed can act as a natural pest deterrent.
3. Sunflowers
Sunflowers are not only attractive to humans but also attract a range of beneficial insects. These tall, showy flowers are particularly appealing to bees, providing them with a rich source of nectar and pollen. Bees play a crucial role in pollinating plants, resulting in better fruit and vegetable yields in the raised bed garden.

Additionally, dill flowers attract pollinators like bees and butterflies, making it a valuable companion plant in raised beds.
5. Calendula
Calendula, also known as pot marigold, is a beautiful flowering plant that attracts hoverflies and bees. Hoverflies are natural predators of aphids and other small insects, making them valuable allies in the fight against pests. Calendula's bright orange petals also add color and visual interest to the raised bed garden.
