Consider helping the native and solitary bees, such as the Orchard Mason Bee with a "bee house".
"Bee houses (or bee hotels) are similar to bird houses, but instead of attracting birds, they attract native solitary bee species. Unlike honey bees, these solitary bees are extremely docile and up to three times more effective as pollinators. No, you won’t get any honey, but you will enjoy better flowers, thriving plants, and healthier vegetables in your garden!"
Learn how to maintain a backyard bee house for native, solitary bees—like mason bees—which can improve your garden's crop and flower yields significantly.
