One of the most effective and natural ways to improve the health of your organic garden is by attracting beneficial insects. These insects, including pollinators and natural predators, help control pests and enhance pollination, leading to healthier plants and more bountiful harvests. By planting specific flowers, you can create a vibrant ecosystem that supports beneficial insects. Here’s a guide to flowers that attract beneficial insects and how to incorporate them into your garden.
