Companion Plants for Sunflowers

Companion planting is a practice in agriculture where certain plants are grown together to enhance each other’s growth and repel pests. When it comes to sunflowers, there are several companion plants that can be beneficial in terms of pest control, nutrient uptake, and overall garden health.

1. Marigolds

Marigolds are often considered the perfect companion plant for sunflowers. Their strong scent repels many common garden pests, including aphids, nematodes, and beetles. Additionally, marigolds attract beneficial insects like ladybugs and lacewings, which feed on harmful pests. Planting marigolds around sunflowers can help protect them from insect damage.

2. Nasturtiums

Nasturtiums are another excellent companion plant for sunflowers. These vibrant flowers act as a natural trap crop, attracting aphids and other pests away from sunflowers. Nasturtiums are also known to repel whiteflies and squash bugs. Their trailing vines can provide ground cover, reducing weed growth and conserving soil moisture.
