(MCT)—After our seemingly endless winter, most of us are itching to load up on plants and get our hands dirty. Whether you grow on a grand scale or tend a couple of pots, chances are you’ll be buying plants at a garden center or plant sale. When you do, a growing chorus of voices is urging you to keep bees in mind.
Bee die-offs, colony collapse disorder and possible causes have made headlines. They’ve also “made the public aware of our stewardship role with bees,” said Vera Krischik, associate professor of entomology at the University of Minnesota.
In fact, bee-friendly gardening was named a top national trend for 2014 by the Garden Media Group.
“Here in Minnesota, there’s a lot going on with bees,” said Lex Horan, Minneapolis-area organizer for the Pesticide Action Network North America, which helped organize a “swarm” at a Minneapolis Home Depot in February to urge the retailer to stop selling products believed to be toxic to bees.
People have been packing auditoriums for bee seminars, pushing for new legislation to protect bees and beekeepers and urging retailers to stop selling and using neonicotinoids, a widely used class of insecticides that some suspect is playing a role in recent bee die-offs.
Research on neonicotinoids’ impact on bees is underway. But in the meantime, several large local players, including retailers Bachman’s and Gertens and wholesale grower Bailey Nurseries, have decided to err on the side of caution and eliminate or sharply reduce their use of neonicotinoids.
Trying not to kill bees is only one piece of the pollinator-protection puzzle, however.
With more and more habitat lost to development and agriculture (corn and soybeans, the state’s top crops, don’t provide nectar), bees need food, too. And that’s where home gardeners can really help, according to experts.
“The main thing is to plant more flowering plants,” said Heather Holm, of Minnetonka, Minn., a landscape designer and author of the new book “Pollinators of Native Plants: Attract, Observe and Identify Pollinators and Beneficial Insects With Native Plants” (available at www.pollinatorsnativeplants.com ).
Native bees, in particular, have a short flight distance — about 500 yards, she said. “If you and your neighbors aren’t providing forage, they will have a hard time finding food.”
From the pollinators’ perspective, it’s important to have a continuous succession of plants flowering throughout the growing season, Holm said. “In most gardens there is a gap,” especially in early spring and late fall. Holm advises gardeners to evaluate their landscape, identify the flower gaps and fill them. Good early-spring bloomers are woodland plants, such as bloodroot, Dutchman’s breeches and wild geranium. Good fall bloomers include asters and goldenrod.
And all flowering plants aren’t equal, from the bee’s perspective. “Stick with straight species” rather than cultivars, Holm advised. “If breeding has changed the flower color, it can also change the fragrance or nectar. It may look better to us, but it may not be attractive to bees.”
When choosing plants, opt for older, simpler varieties, Holm said, even if it means passing up the plants that catch your eye with their showy form or unusual hue. “Rethink how a bee or pollinator would see your garden — not just what you think is prettiest, with double flowers or a brand-new introduction in a cool color,” she said.
