Nurturing Nature in Your Yard
Newsletter A reader wanted to attract pollinators and foster biodiversity without spending a bundle to redo her property. Weve got tips. Gabrielle Stevenson needed advice on how to welcome pollinators and other wildlife to her front yard in Roseville, Calif. She knew that replacing part of her lawn with native plants was the best way to nurture biodiversity there. But she didnt want a mess and didnt know where to begin. She also didnt have thousands of dollars to hire a professional landscaper. Which plants should she buy? How should she arrange them? To be honest, I find it quite daunting, she wrote in an email to us last month. It can be. But its worthwhile, according to scientists. Native flowers, grasses, shrubs and trees in cities and towns offer food and habitat for wildlife facing alarming declines, particularly and . They also save water, since native species, when theyre placed in an appropriate spot, generally dont require watering once established. It seemed like a good topic on Earth Day Eve. So, for guidance on how people can get started without much time or money, I called Rebecca McMackin, the former director of horticulture at Brooklyn Bridge Park, an urban wildlife haven that attracts rare insects like the two-spotted lady beetle and the golden northern bumblebee. Heres what she had to say. Its true that gardens take effort, McMackin said. Theres the research, the money, the maintenance. So, she advises cautious newbies to start small. Pick a corner of your lawn to replace first, rather than the whole thing, McMackin said. Pay attention to how sunny or shady, wet or dry it is, because youll choose your plants accordingly. If its a small area, you can pull out the grass yourself, with your hands or with the help of a spade or shovel. Instead of discarding the grass, McMackin suggests, simply shake off the soil and place it to the side, roots up, to return to the earth. Insects cant eat just any plants. Theyve evolved over thousands of years to consume certain kinds. The most famous example in North America is the monarch caterpillar, which can eat only milkweed. Oak trees, the heavy hitters of host plants, feed . But many plants that are widely used in American gardens are food deserts to local caterpillars. One reason caterpillars are important: . Wherever you are, the best thing to do is to plant butterfly host plants, McMackin said. They are just an absolutely magical thing that people can do that really illustrates the beneficial impact that we can have so quickly. To find host plants in the United States, you can plug your ZIP code into the . Their data is from Doug Tallamy, a professor of entomology at the University of Delaware whose work has helped catalyze a growing native plant movement. Many native flowers evolved alongside tall grasses that acted as natural scaffolding. When planted alone in a garden, these lanky species can lean over. Plants that are taller than two feet can look wild and messy if not sited or arranged properly, McMackin said. Keeping plants low will maintain a managed aesthetic. In much of the eastern half of the United States, one option is eastern red columbine, host to the columbine duskywing, among other insects. It blooms when ruby-throated hummingbirds are migrating back from Mexico, and the birds are drawn to the red flowers. The ruby-throated hummingbird is the pollinator partner for that flower, McMackin said. Without that bird, those flowers are not going to reproduce as much. And those birds have come to rely on that flower when they get here. (The West has its own , which also nourish hummingbirds.) We often imagine ornamental gardens filled with nothing but flowers, McMackin said. But shrubs are beautiful, highly beneficial for wildlife, and less work than most garden perennials. So are trees, which have been called meadows of the sky, offering flowers to pollinators and leaves to caterpillars. An enormous fraction of North Americas butterfly and moth caterpillars many thousands of species are known to feed on just a couple dozen kinds of woody plants, said David Wagner, an entomologist at the University of Connecticut who specializes in caterpillars. Trees also , stash carbon out of the atmosphere, filter air and suck up storm water. Search the internet for native plant nurseries in your area. People who work there are a good resource for questions, too. Bigger nurseries are starting to carry more native species, but be sure to ask whether theyve been treated with pesticides. Many states have native plant societies that keep track of pop-up sales in your area. Some can also point you to plant lists and sample designs, .
