Garden Guidance: Turn Your Yard Into A Pollinator Paradise

Did you know that almost all of the world’s plants need to be pollinated? Bats, birds, beetles, bees, butterflies, wasps, and moths all play this essential role in ecosystems and are crucial in the reproduction of two-thirds of the all crop species. Sadly, many pollinators are in rapid decline. About a decade ago, beekeepers in the United States and abroad started seeing a concerning drop in honeybee populations.

According to Eric Lee-Mader, pollinator conservation co-director for The Xerces Society for Invertebrate Conservation, it is common for beekeepers to lose 15% of their hives each year from winter starvation and other factors. In 2004 and 2005 however, beekeepers began to lose 30, 40 or even 50 percent of the hive population annually. Beekeepers and scientists alike are baffled and trying to determine the exact cause. There are likely several factors: parasites, persistent pesticides (neonicotinoids), and habitat loss working together.

Although loses in honeybee populations can have a financial impact, loses in native pollinators can be less quantifiable, but of great importance. Native pollinators provide essential agricultural services, estimated at $3 billion annually in the United States alone.

From leafcutter bees to bumble bees to mining bees, there is great diversity in the wild bee population of North America. Mader says there are roughly 4,000 species that are truly native to the continent and are highly adapted to native crops.  Although honeybees are not going extinct, there are native bee extinctions that are taking place in the United States. The rusty patched bumble bee, for example was once very common here and may go extinct this year. 

While pesticide use, habitat loss, and the introduction of diseases are the main causes of declining pollinator populations, our gardens can be mini sanctuaries for pollinators. Follow these tips from the United States Forest Service to keep our pollen-loving friends healthy and plentiful.

Avoid hybrid flowers, especially “double” flowers

To create the perfect bloom, plant breeders often sacrifice the pollen, nectar, and fragrance, which are unfortunately essential for pollinators.

Increase visibility of plants to pollinators

Design your garden to plant in groups or drifts rather than as single plants to enable pollinators to locate blooms, and plant a variety of colors to attract a variety of pollinators.

Provide larval host plants

To attract colorful butterflies, grow plants for their caterpillars to feed on. Some species, such as monarch butterflies, are only attracted to one or two plant species. Attract monarchs with milkweed, and black swallowtails with dill, carrot, parsnip, or parsley. Many larval host plants will experience leaf damage, an indication they are providing benefit, so locate them where they will not be an eye sore.

Create a salt lick for butterflies and bees

Provide damp soil with a drip hose or birdbath on bare soil, and mix in wood ash or sea salt into the mud. Some butterfly species also enjoy fruit, so leave out an over-ripe banana, apple or orange on top of a sponge in a dish with slightly salted water for a nice snack.

Grow pollinator-attracting native plants

Native plants are four times more attractive than non-native plants to pollinators. In addition, native plants usually require less maintenance because they are ideally suited to the local environment.

Leave dead wood for nesting

Most bees are solitary species, meaning that a female bee will mate and they lay eggs in cells by herself. Providing dead trees or even a dead limbs for nesting sites for native bees can help them thrive. Another option is to drill holes ranging from 3 to 5 inches deep on scrap lumber mounted on posts or eaves.

 Add a nectar source with a hummingbird feeder

Make artificial nectar by mixing four parts water with one part sugar, and never use artificial sweeteners, juice, or honey. Dissolve sugar and allow it to dry before placing in a red colored feeder.

Cultivate plants that are pollen and nectar sources throughout the growing season

Provide a wide range of plant, including perennials and annuals, with a variety of flower shapes and sizes. Also, grow night-blooming flowers to encourage moth and bat populations.
