If you want natural, organic pest control and better crops or blooms, you need more beneficial insects in your garden.
Bees, butterflies, hoverflies, and wasps all need a few essential elements in a garden to thrive.
Umbel-shaped blooms such as yarrow and buckwheat are the preferred food source of many beneficial insects.
Other insects prefer flowers that have a central cone that serves as a landing pad, such as blanket flower and coneflower.
The larvae of many beneficial insects need their own food sources. In Northern California, native narrowleaf milkweed (left) is an excellent host plant for monarch caterpillars (right).
