Pollinators like bees and butterflies need help during winter to survive and thrive in spring. By making small, intentional changes in your yard, you can protect their habitats and support ecosystems. Here’s how:
- Leave plant stems and seed heads standing: These provide shelter and nesting spots for solitary bees.
- Keep leaf litter: It acts as insulation and protects insects like moths and ground-nesting bees.
- Plant native species: They support local wildlife and stay resilient through winter.
- Create brush piles and bare ground: These offer shelter and nesting areas for various pollinators.
- Provide water: Use shallow containers with stones to ensure pollinators can safely drink.
- Avoid pesticides: Protect overwintering insects by skipping chemicals and minimizing soil disturbance.
- Plan for year-round blooms: Ensure food sources are available in every season by planting native flowers with staggered bloom times.
These steps not only help pollinators survive the cold but also prepare your garden for a vibrant spring.
Gardening for Pollinators in Fall and Winter (Online Lecture)
1. Keep Plant Stems and Seed Heads Standing
Skip the fall garden clean-up if you want to give pollinators a helping hand through the winter. While dried stems and seed heads might not win any beauty contests, they’re essential for supporting beneficial insects. These leftovers from your garden serve as both shelter and food for various pollinators, especially solitary bees.
Take mason and leafcutter bees, for example. These solitary bees use hollow or pithy stems to create their nests. By cutting back perennials in the fall, you could unintentionally destroy these vital homes.
Native plants with sturdy, long-lasting stems are the best option to keep your garden pollinator-friendly. Consider planting perennials like coneflowers (Echinacea spp.), sunflowers (Helianthus spp.), black-eyed Susans (Rudbeckia spp.), Joe-Pye weed (Eutrochium spp.), and goldenrod (Solidago spp.). These plants not only provide structure but also offer food and shelter during the colder months.
Height is another important factor. Experts suggest leaving stems at least 12 inches tall [4] to give pollinators enough space to nest and overwinter. If you absolutely need to trim, hold off until late spring when pollinators have emerged from their winter hideouts. When you do trim, focus only on diseased stems, leaving the healthy ones intact to protect both your garden and its tiny inhabitants.
There’s an added bonus: those standing stems will naturally break down over time, enriching the soil and reducing the need for extra fertilizer. By leaving these winter structures in place, you’ll not only help pollinators but also boost the overall health of your garden’s ecosystem.
2. Keep Leaf Litter and Natural Mulch
Fallen leaves aren’t just a yard chore – they’re a lifeline for pollinators during the winter months. While many homeowners rush to rake and bag them, leaving some leaf litter in place can make a big difference for beneficial insects trying to survive the cold season.
Just like standing plant stems provide a safe haven, leaf litter acts as a protective blanket. It insulates pollinators such as luna moth and swallowtail butterfly pupae and supports about 70% of native bees that nest in the ground [3][4]. Ground beetles and solitary bees rely on this natural layer for warmth and protection from predators. A study by the Xerces Society revealed that removing leaf litter can reduce butterfly and moth populations by as much as 80% in managed landscapes [2]. That’s a huge loss for ecosystems!
Beyond helping pollinators, decomposing leaves improve soil health by adding nutrients, which can reduce the need for fertilizers [2][3]. If you’re worried about your yard’s appearance, there are ways to make leaf litter work for you. Move it to less visible spots like under shrubs, around tree trunks, or in garden beds. You could even shape it into decorative mounds or spirals that look intentional while still serving as a habitat [2][3].
For the sake of overwintering insects, it’s best to wait until late spring – when temperatures are consistently around 50°F – before clearing away the leaves. This ensures pollinators have had enough time to emerge safely [1][3].
If you’re in Maryland, Pro Landscapes MD can help you incorporate leaf litter into your garden design. By maintaining this natural cover, you’re not just helping pollinators now – you’re laying the groundwork for a thriving habitat in the future.
3. Choose and Plant Native Species for Winter Interest
Native plants play a crucial role in creating successful winter habitats for pollinators while adding visual appeal to your garden. Unlike non-native species, which often struggle with Maryland’s climate or fail to meet the needs of local wildlife, native plants have evolved alongside local pollinators over thousands of years. This natural partnership ensures they reliably support pollinators during the colder months.
Take winterberry holly (Ilex verticillata), for example. Its vibrant red berries brighten up winter landscapes while providing essential food for birds. The dense branches also offer shelter for overwintering insects. Similarly, Eastern red cedar (Juniperus virginiana) delivers year-round evergreen foliage, acting as a windbreak and protective cover. Meanwhile, switchgrass (Panicum virgatum) holds its structure through winter, with seed heads feeding birds and hollow stems serving as nesting sites for solitary bees.
Even plants like coneflowers (Echinacea spp.) and goldenrod (Solidago spp.), which may appear dormant above ground, remain busy supporting wildlife. Their standing stems offer nesting spots for beneficial insects, and their seed heads provide much-needed food for birds throughout the season. What sets these native plants apart from ornamental varieties is their perfect timing – they bloom, seed, and go dormant in harmony with the needs of local wildlife. This natural rhythm makes native species both beautiful and ecologically valuable.
To establish these plants successfully, consider planting native wildflowers in the fall or early winter. Many species require 30–90 days of cold, moist stratification [5] to germinate, ensuring they’re ready to support pollinators come spring.
For the best results, cluster native plants in groups of three to five [3]. This arrangement increases pollinator activity, even during those brief warm spells in winter.
If you’re unsure where to start, Pro Landscapes MD’s horticulturists specialize in identifying the best native species for Maryland’s unique soil and climate. Their expertise in site preparation, plant selection, and placement can help you create a garden that not only looks great year-round but also serves as a thriving ecosystem for pollinators and wildlife.
4. Create Shelter with Brush Piles and Bare Ground
Preserving natural elements in your garden can go a long way in supporting pollinators, especially during Maryland’s chilly months. One simple yet effective way to help is by creating brush piles and leaving patches of bare ground. These features might look a bit untidy, but they serve as vital shelters for various pollinator species.
To start, loosely stack pruned branches, twigs, and dead stems to form crevices. These crevices provide protection for solitary bees like mason and mining bees, as well as butterflies such as swallowtails and fritillaries, shielding them from freezing temperatures and harsh winds[3][4].
Building a brush pile is straightforward. Use large logs as a base, then layer smaller branches and twigs on top to create multiple hiding spots. Place the pile in a quiet, partly sunny area that’s shielded from strong winds. Be sure to use untreated, noninvasive wood for safety[2][3].
Bare ground patches are equally important. Around 70% of native bee species in North America are ground-nesters. These bees dig tiny burrows in the soil to overwinter, but they can’t do so if the ground is covered by thick mulch, dense grass, or hardscaping materials[3][6].
Set aside small, sunny areas with well-drained soil – just a few square feet – free of mulch and vegetation. These patches, placed near flower beds or along garden edges, give ground-nesting bees a safe spot for overwintering and easy access when they emerge in spring[3]. It’s also important to avoid disturbing these areas or walking on moist soil during fall and winter, as this can damage the bees’ burrows[1].
For gardeners in Maryland, these features can be tucked into less visible parts of the yard. Keep brush piles away from the house, and limit bare patches to small, intentional spaces. This approach balances aesthetics with the added benefit of attracting more pollinators to your garden[3].

5. Provide Access to Water
Even during winter, pollinators need access to water for hydration. However, natural water sources often freeze or become scarce in Maryland’s colder months, making it essential to offer reliable alternatives in your garden.
To address this, use shallow containers that are safe and easy for pollinators to access. Look for dishes or trays no deeper than 1–2 inches, as deeper containers can pose a drowning risk for smaller insects. Fill these with clean water and add pebbles, stones, or marbles to create safe landing spots where pollinators can perch while drinking[2].
During freezing weather, place these water sources in sunny, sheltered areas near pollinator-friendly plants or brush piles. South-facing locations that receive plenty of sunlight can help reduce freezing, while spots shielded from strong winds make the water more inviting. Check these water stations daily, replacing frozen water with fresh, lukewarm water as needed. A simple trick to keep water from freezing is to float a small ball on the surface, which can help maintain an open area. For harsher conditions, consider using heated birdbaths to ensure a consistent water supply. On warmer winter days, when pollinators are active – even with snow on the ground – snow and ice alone often fail to meet their hydration needs, especially in urban and suburban areas.
You can create a simple drinking station using a ceramic or plastic saucer filled with water and pebbles. Alternatively, repurpose items like pie tins or plant trays, adding stones for safe access.
For gardeners looking to elevate their water features, Pro Landscapes MD offers custom solutions that combine practicality with aesthetic appeal. Now, let’s explore other ways to minimize disruptions for pollinators in your garden.
6. Skip Pesticides and Limit Disturbance
Winter is a crucial season to steer clear of pesticides in your pollinator-friendly garden. Many pollinators spend these colder months in a dormant state, hiding as eggs, larvae, or adults nestled in leaf litter, hollow stems, or the upper soil layers. Even a single pesticide application can harm these overwintering insects and disrupt their food sources, potentially reducing their survival come spring [2][3].
Did you know that over 70% of native bee species nest in the ground? This makes undisturbed soil and leaf litter absolutely essential for their survival [3]. Excessive raking, soil tilling, or chemical treatments can destroy these critical winter shelters, leaving pollinators without a safe place to weather the cold.
Physical disturbance can be just as harmful. That pile of leaves you might be tempted to clear away? It’s a lifeline for many beneficial insects. Those dry, brown plant stems that look lifeless? They’re often winter homes for solitary bees and caterpillars, providing protection from freezing temperatures and predators [3].
Instead of reaching for pesticides, rely on nature’s own pest control methods. Birds, beneficial insects, and a diverse range of plants can naturally keep pests in check without harming overwintering pollinators. If you need to address diseased plants, remove only the affected parts and handle them gently to minimize disruption to the surrounding habitat [2][3].
Another effective strategy is to adopt rotational garden maintenance. Leave about one-third of your garden or meadow untouched each year, rotating the areas left undisturbed. This ensures that pollinators with varying emergence times always have a safe place to overwinter [1].
The U.S. Fish & Wildlife Service sums it up perfectly: sometimes, doing less is the best way to help pollinators [3]. In Maryland, for instance, gardeners have discovered that leaving natural debris in place significantly boosts pollinator survival in the spring [3].

7. Plan for Year-Round Blooms and Future Habitat Improvements
Winter is the perfect time to map out a pollinator-friendly habitat that provides food and shelter across all seasons. By planning for continuous blooms, you can ensure pollinators have access to reliable food sources during critical times, like early spring and late fall, when natural options are scarce [3]. This planning builds on the habitat maintenance you’ve already tackled during the colder months.
Focus on planting native Maryland species that bloom in different seasons – spring, summer, and fall. Choose plants with staggered flowering times so there’s always something in bloom from early spring through late fall [3][4]. A simple way to do this is by charting bloom periods to spot and fill any seasonal gaps in your current garden. This ensures pollinators have a steady supply of nectar and pollen, even when nature’s pantry is running low.
Winter is also a great time to prepare your garden for new growth. Remove invasive plants, improve soil conditions, and plan new planting areas [5]. For larger projects, you might need several rounds of treatment to fully eliminate non-native grasses before introducing native plants. These steps help create a healthier environment for pollinators in the upcoming seasons.
If you’re planning to seed wildflowers, take advantage of winter’s natural cold stratification process. Many wildflower seeds need 30–90 days of cold, damp conditions to sprout [5]. By scattering or drilling native wildflower seeds into prepared soil in late fall or early winter, you let the weather do the hard work. Lightly rake the seeds to improve contact with the soil, but don’t bury them too deeply – many wildflowers need sunlight to germinate [5]. Pair this seeding approach with a diverse selection of plants to cover any seasonal gaps.
Incorporating a variety of flower shapes and colors can attract a wider range of pollinators. Additionally, adding features like brush piles or leaving areas of bare ground can support the 70% of native bees that nest in the soil [4].
