How to Help Overwintering Pollinators

Raise your hand if you want to help butterflies, bees, and other pollinators. Good for you.

In my last blog post, I discussed two ways to help pollinators starting in the fall. Waiting to cut back perennials until spring and letting some leaves lie protects overwintering insects.

But there is so much more you can do to help this fall and year-round. It’s all about creating habitat, providing safe spaces for pollinators to live, eat, shelter and raise young.

My neighbors raised their eyebrows when I plunked a moss-covered log into my landscape. But it looks terrific in my woodland garden, a natural accent that provides shelter and food for wildlife.

So, adopt a log. Spiders and beetles are attracted to the moist areas under logs and peeling bark. Bees and butterflies nest and overwinter in drier parts of logs.  

Logs help other wildlife, too. Chipmunks use them as highways, toads love their moisture, and other critters use them for sunbathing. 

Lay logs horizontally, burying one end a few inches to maintain some moisture. And be sure to ask permission before tossing that log into your pickup. Mine came from a family property. Honest.

Dead-standing trees called “snags” also provide habitat for pollinators and other wildlife. As long as a tree poses no danger to you or your home, consider leaving it. What looks messy to us is beautiful to wildlife. 

Beetles and other insects burrow through dead wood, creating tunnels that cavity-nesting bees such as mason bees lay their eggs in. Other insects tuck under bark. I once saw a striking mourning cloak butterfly emerge from the bark of a dead tree.

If leaving a whole dead tree is too much for your sense of order or safety is an issue, fell the tree but leave the log in part or whole. Or leave just the stump. Hardwood logs with the bark attached add more varied, longer-lasting habitat.

What else can you do to enhance your habitat for pollinators beyond planting native plants that flower from spring to frost? Plenty.  

Add a rock pile or wall. Bumblebees, leafcutter bees, and wasps nest in their cavities. Ground beetles and many other insects shelter where soil meets stone.

Use different sizes and types of rocks and skip the mortar to create more protected nooks and crannies. Planting native plants nearby makes the area even more attractive to pollinators and other beneficial insects.  

Thanks for all you are already doing to help support and protect pollinators. It matters.
