Leave the Leaves: How Your Fall Garden Helps Native Bees Survive Winter
Your fall garden provides important winter habitat for native bees and other pollinators. Learn why leaving leaves, stems, and natural spaces can help bees survive until spring
When autumn arrives, our first instinct is often to clean up the yard. We rake the leaves, cut back dead flowers, trim stems, and prepare the garden for winter.
But if you want to help native bees and other pollinators, doing a little less may actually be better.
Fallen leaves, hollow plant stems, loose bark, and other natural garden materials can provide important habitat for insects during the colder months. Instead of clearing everything away in the fall, consider letting part of your garden remain a little wild until spring.
Where Do Native Bees Go in Winter?
Honey bees and native bees survive winter very differently.
Honey bees live together in colonies and remain inside their hive during cold weather, clustering together and generating heat to protect the colony.
Most native bee species, however, are solitary. Depending on the species, they may spend winter underground, inside hollow or pithy plant stems, in cavities, or in other protected spaces.
In many cases, the bees you are protecting aren't active adult bees at all. They may be developing larvae or pupae waiting for warmer weather to emerge.
That makes an undisturbed garden valuable habitat.
Why Fallen Leaves Matter
A layer of fallen leaves is more than yard debris.
Leaves create an insulating layer over the soil and provide shelter for insects and other small animals. Butterflies, moths, beetles, and other beneficial insects may spend part of their life cycle protected within leaf litter.
Removing every leaf from a garden can also remove some of the habitat these species depend on.
You don't necessarily have to leave your entire lawn covered in leaves. Instead, move some leaves into garden beds, beneath trees, or into less-trafficked areas where they can remain undisturbed through winter.
Leave Some Dead Stems Standing
Those brown flower stalks may not look impressive in January, but they can be useful habitat.
Some cavity-nesting native bees use hollow or pithy stems as nesting sites. Cutting every plant to the ground in fall can eliminate potential places for bees to nest and develop.
Consider leaving dead stems standing through winter and into spring.
When you eventually trim them, leaving portions of the stems standing can continue to provide nesting opportunities for cavity-nesting bees.
Don't Rush Your Spring Cleanup
The first warm afternoon of the year can make it tempting to start raking, pruning, and clearing immediately.
Give your garden some time.
Pollinators don't all emerge at once, and a few warm daytime temperatures don't necessarily mean the insects using your garden are ready to leave their winter shelter.
Instead of choosing a cleanup date simply because the calendar says spring has arrived, pay attention to local conditions and signs of sustained warmer weather.
You can also clean your garden gradually rather than removing everything at once.
What About Bee Houses?
Bee houses can provide nesting cavities for certain species of solitary bees, but they need to be managed properly.
If you install one, choose a design that can be cleaned or maintained and place it in an appropriate location. Poorly maintained bee houses can accumulate moisture, parasites, and disease.
A bee house can be useful, but it shouldn't replace natural habitat.
Standing stems, patches of bare soil, native plants, leaves, and pesticide-free areas can all help create a healthier environment for native bees.
5 Easy Ways to Help Bees This Fall
You don't need to transform your entire yard into a wildlife preserve. A few simple changes can make your property more welcoming to pollinators:
- Leave some fallen leaves in garden beds and beneath trees.
- Keep some dead flower stems standing through winter.
- Avoid disturbing bare soil where ground-nesting bees may be developing.
- Reduce or eliminate pesticide use around pollinator habitat.
- Wait before doing a complete spring cleanup so overwintering insects have time to emerge.
A slightly messier garden can be a much more useful garden.
A Little Less Yard Work Can Help a Lot
Nature doesn't clean up for winter.
Leaves fall. Flowers die back. Stems dry out. Bark loosens. And all of those things become part of an ecosystem that provides food, shelter, nesting material, and protection for countless species.
This fall, consider putting the rake away a little earlier.
Leave some leaves. Keep some stems. Give a corner of your yard back to nature.
The bees might thank you for it.
Help Build a More Sustainable Future for Bees
Supporting bees goes beyond what we plant in our backyards.
Bee Mission is working to build a more sustainable future for bees and beekeeping by creating greater demand for beekeeper-produced honey and supporting the people who care for managed honey bee colonies.
