How Certain Plants Help Bees Survive Winter

When most people think about supporting pollinators, they picture bright summer flowers and buzzing gardens. But the truth is this: bees need help long before spring arrives. Winter is one of the most critical periods for their survival, yet also the most overlooked.

Understanding what bees actually do over winter can help you make informed decisions about your landscape, your trees, and your property. And with just a few strategic plant choices, you can play a direct role in supporting bees during the coldest, harshest months of the year.

What Bees Do During Winter

Different types of bees have different survival strategies and understanding them is key to helping them thrive.

Honeybees

Honeybees do not hibernate. Instead, they form a tight winter cluster inside the hive. Thousands of bees surround the queen and vibrate their flight muscles to generate heat, effectively becoming their own furnace.

This requires enormous energy reserves, which come from stored honey and any late-season nectar they gather before temperatures drop. On warm winter days, honey bees may fly briefly to stretch, clean, and collect nutrients if they find any.

Native Solitary Bees

Most native bees—mason bees, leafcutter bees, miner bees, carpenter bees—spend winter in a dormant phase called diapause.

Depending on the species, they might overwinter as larvae, pupae, or fully formed adults inside:

• Hollow stems
• Underground burrows
• Cracks in wood
• Leaf litter
• Bee hotel tubes

These bees don’t need a hive, but they do need undisturbed habitat.

Bumble Bees

As cold weather arrives, the entire bumble bee colony dies off except for newly mated queens. These queens dig a small hole in the soil and hibernate alone until spring, when they emerge to start a brand-new colony.

Why Supporting Bees During Winter Matters

Healthy bee populations don’t begin in spring; they begin in fall.

1. Winter determines spring survival.

If bees go into winter underfed, with low fat reserves, their survival rate plummets. Even if they make it through, they may emerge weak, produce fewer offspring, and struggle through early spring.

2. Winter flowers offer real value on warm days.

During occasional warm spells, honeybees leave the hive to replenish energy. If your yard has winter-blooming plants, you could be providing the only nectar source within miles.

3. Habitat determines whether native bees return next year.

Cutting down all stems, removing all leaves, or over-mulching eliminates habitat for solitary bees and bumblebee queens. If their overwintering spaces disappear, so do they.

4. Strong bees mean better pollination and healthier trees.

Pollinators are an important part of the larger ecosystem that supports trees and the landscapes most property owners care about. Supporting bees isn’t just environmental—it’s practical.

Late-Fall and Winter Plants That Support Bees

These plants help bees build up reserves before winter or provide food during mild spells.

Late-Fall Bloomers

These plants are critical for winter prep. They help bees gather the final nectar and pollen reserves they need before winter dormancy begins.

• Asters
• Goldenrod
• Sunflowers
• Joe-pye weed
• Sedum ‘Autumn joy’
• Japanese anemone
• Helenium
• New England aster

Winter-Blooming Plants

These plants are lifesavers on warm days. They are great for regions that experience milder winters or occasional thaws. Even a handful of these can offer crucial winter resources.

• Witch hazel
• Hellebores (Lenten roses)
• Mahonia (Oregon grape)
• Winter jasmine
• Calendula
• Winter heather

Early-Spring Bloomers

Early spring can be "make or break" for bees. These plants help them recover quickly when they are at their weakest.

• Willows
• Maples
• Redbud
• Pussy willow
• Crocus
• Snowdrops
• Lungwort (Pulmonaria)
• Grape hyacinth

Habitat Choices Matter as Much as Plants

If you want to help pollinators survive winter, consider these simple property and landscape practices:

Leave the Leaves

Many native bees overwinter in leaf piles. Letting even part of your yard remain natural gives them a place to shelter.

Leave Hollow Stems Until Spring

Don’t cut back perennials until April, if you can. Hollow stems often house solitary bees in cocoons.

Avoid Over-Mulching

70% of native bees nest in soil. Leaving some bare ground exposed supports ground-nesting species.

Choose Native Plants

Native flowering trees, shrubs, and perennials match the life cycles and nutritional needs of local bee species better than most imported ornamentals.
