Best Plants to Attract Digger Bees to Your Yard

Digger bees are fascinating solitary pollinators that play a crucial role in the health of our ecosystems. Unlike social bees such as honeybees or bumblebees, digger bees live alone and nest underground, often in sandy or loose soil. Attracting these beneficial insects to your yard can enhance pollination for your garden plants and contribute to biodiversity. One of the best ways to invite digger bees is by planting the right flowers and plants that provide food and habitat.

In this article, we’ll explore the best plants to attract digger bees, their benefits, and how to create a bee-friendly environment in your yard.

Why Attract Digger Bees?

Before diving into the plant selection, it’s important to understand why digger bees are worth attracting:

• Excellent Pollinators: Digger bees efficiently pollinate native wildflowers, vegetables, fruits, and garden plants.
• Non-Aggressive: These solitary bees are generally non-aggressive and rarely sting unless directly threatened.
• Biodiversity Boosters: They support ecological balance by pollinating native plants and providing food for other wildlife.
• Soil Aeration: Their nesting behavior aerates the soil, improving its health and fertility.

Creating an environment that supports digger bees benefits both your garden and the wider environment.

What Do Digger Bees Need?

Digger bees primarily require two things:

1. Floral Resources: Nectar and pollen-rich flowers for food.
2. Nesting Sites: Undisturbed bare or lightly vegetated patches of well-drained soil for digging nests.

Your plant choices should focus on native, pollen-rich flowers that bloom at different times to provide continuous forage throughout the growing season.

Best Plants to Attract Digger Bees

1. Wildflowers

Wildflowers are among the top choices for attracting digger bees because they tend to be native to the area and well-suited for local pollinators.

• Black-eyed Susan (Rudbeckia hirta)
  Bright yellow petals with a dark center, black-eyed Susans bloom mid-summer through fall and offer abundant pollen.

• Purple Coneflower (Echinacea purpurea)
  Known for their large pinkish-purple petals, these flowers bloom mid-summer and provide ample nectar.

• Wild Lupine (Lupinus perennis)
  These tall spikes of blue-purple flowers bloom in spring and early summer, attracting many types of solitary bees.

• Bee Balm (Monarda didyma)
  With vibrant red, pink, or purple tubular flowers blooming mid-summer, bee balm is a magnet for pollinators.

2. Native Perennials

Native perennials often provide reliable sources of nectar year after year with minimal care.

• Goldenrod (Solidago spp.)
  Blooming late summer into fall, goldenrod’s bright yellow clusters are critical late-season forage for digger bees preparing for winter.

• Penstemon (Penstemon spp.)
  Bell-shaped flowers in shades of pink, purple, or white bloom in late spring through summer.

• Asters (Symphyotrichum spp.)
  Fall-blooming asters bring much-needed pollen late in the season with star-shaped purple or white flowers.

• Milkweed (Asclepias spp.)
  Besides supporting monarch butterflies, milkweed flowers attract many bee species with their nectar-rich blooms.

3. Herbs That Attract Bees

Many herbs produce aromatic flowers that appeal to solitary bees including digger species:

• Lavender (Lavandula spp.)
  The fragrant purple flower spikes bloom from late spring into summer and attract a variety of pollinators.

• Thyme (Thymus vulgaris)
  Small purple or pink blossoms in early summer provide nectar sources in rock gardens or herb beds.

• Borage (Borago officinalis)
  Blue star-shaped flowers bloom all summer long offering excellent pollen and nectar supplies.

• Catnip (Nepeta cataria)
  Producing lavender-colored blooms from spring through fall, catnip attracts many native bees.

4. Legumes

Plants from the pea family (Fabaceae) are favored by many digger bees because they offer protein-rich pollen:

• Clover (Trifolium spp.)
  Both white and red clover bloom from spring through fall and are excellent forage plants for ground-nesting bees.

• Lupines (mentioned above) also belong to this family with their nitrogen-fixing ability improving soil health alongside supporting pollinators.

5. Annual Flowers

Incorporate some annuals if you want quick blooms that also attract digger bees:

• Cosmos (Cosmos bipinnatus)
  With delicate daisy-like flowers in shades of pink, white, or orange, cosmos blooms from summer until frost.

• Sunflowers (Helianthus annuus)
  Large heads filled with pollen-rich florets bloom mid-summer into fall attracting many pollinators including ground-nesting bees.

Creating a Habitat for Digger Bees

Plant selection is only part of the equation; creating the right environment is equally important for attracting digger bees.

Provide Bare Ground for Nesting

Digger bees nest underground by excavating tunnels. They prefer dry, sandy or loose soil with plenty of sunlight. Maintain patches of bare ground free from mulch, plants, or heavy foot traffic where they can dig safely. Avoid tilling these areas during nesting season (spring to early summer).

Reduce Pesticide Use

Avoid chemical insecticides and herbicides that can harm solitary bee populations. Opt for organic gardening practices or use targeted pest control methods that minimize damage to beneficial insects.

Provide Water Sources

A shallow water source like a birdbath with stones or a shallow dish helps bees hydrate—especially important during hot summer months.

Plant Diverse Blooms

Include a variety of flower shapes, colors, and bloom times to supply continuous nectar and pollen throughout the growing season. Diversity supports different bee species’ preferences as well as enhances ecosystem health.

Avoid Lawn Monocultures

Lawns offer little forage value. Replace parts of turf with flowering ground covers or wildflower patches to make your yard more attractive to pollinators including digger bees.

Seasonal Bloom Timing Tips

To support digger bees year-round:

• Early Spring: Plant crocus, wild lupine
• Late Spring: Include penstemon, thyme
• Summer: Grow bee balm, lavender, cosmos
• Late Summer/Fall: Goldenrod, asters, clover

This succession ensures food availability across all active months for these solitary insects.

Conclusion

Attracting digger bees enriches your garden’s biodiversity while supporting essential pollination services. By planting native wildflowers, perennials, legumes, herbs, and even some annuals combined with providing suitable nesting sites like sunny bare soil patches—your yard will become a haven for these gentle solitary bees. Avoid pesticides and maintain water sources to give them a welcoming environment year after year.

Start by incorporating some of these recommended plants today—your efforts will not only beautify your yard but also nurture vital wildlife making your outdoor space truly flourish.
