Pollinators — bees, butterflies, moths, hoverflies, beetles, and even some birds — are the quiet workforce behind a huge share of the food we grow. If you want healthier crops, better yields, and a more resilient farm ecosystem, attracting and supporting pollinators is one of the highest-return investments you can make.
Why pollinators matter for farms
Quick principles to guide everything you do
- Food + Shelter + Water = Pollinator habitat. Provide continuous bloom, places to nest/overwinter, and water. (U.S. Fish and Wildlife Service)
- Diversity wins. A mix of native perennials, herbs, and annuals that bloom at staggered times attracts a wider range of insects. (NRDC)
- Scale matters. Planting clumps/strips of the same species (rather than single plants scattered) helps pollinators find and use food more efficiently. (SARE)
- Farm practices affect habitat. Minimize disruptive soil tillage near nesting areas and reduce the use of broad-spectrum insecticides. (AgAmerica)
Actionable steps (what to do this season)
1. Map and prioritize
- Crop fields that most need pollination (e.g., squash, cucurbits, almonds, berries).
- Margins, headlands, fallow fields, ditches, hedgerows, and riparian strips, where habitat can be added with low opportunity cost. Start small — a 2–5% area devoted to habitat (flower strips, hedgerows) can yield big pollination benefits for nearby crops. (SARE)
2. Plant for continuous bloom
- Spring: fruit-tree blossoms, willow, early native wildflowers.
- Summer: clover, borage, phacelia, sunflowers, coneflowers.
- Fall: goldenrod, asters, sedum. Aim for at least three species flowering at any time during the season to support different pollinators. (U.S. Fish and Wildlife Service, Ohioline)
3. Use native plants and plant in patches
4. Create nesting and overwintering habitat
- Ground-nesting bees: leave some patches of bare, well-drained soil and minimize tillage there. Up to 70% of bee species nest in the ground, so conserving undisturbed patches is critical. (AgAmerica)
- Cavity nesters (e.g., mason bees): install bee boxes, stems bundles (hollow reeds), or leave standing dead wood.
- Overwintering sites: Leave some leaf litter, undisturbed stems, and brush piles in non-crop areas throughout the winter. (U.S. Fish and Wildlife Service)
5. Provide water and mineral sources
6. Reduce pesticide risks
- Avoid broad-spectrum insecticides during bloom. If treatment is necessary, apply in the evenings or before/after bloom, and target only problem pests.
- Prefer integrated pest management (IPM): monitoring, beneficial insects, trap crops, and spot treatments.
- When possible, switch to selective, low-toxicity products and avoid systemic insecticides during bloom windows. Reducing chemical exposure is one of the fastest ways to improve pollinator presence. (The Spruce)
7. Adjust tillage and cropping timing
8. Design landscape features that scale
- Wildflower strips: plant across field margins or between rows; 3–6 m strips can support strong pollinator communities.
- Hedgerows & windbreaks: native shrubs provide blossoms, berries, and nesting habitat.
- Flowering cover crops: integrate clover, phacelia, buckwheat, or vetch into rotations to provide mass bloom when fields would otherwise be bare. (SARE, North Carolina Field and Family)
9. Partner locally
10. Monitor and adapt
Sample plant list (farm-friendly, broadly useful)
- Early: willow species, crocus (on small scales), fruit-tree blossoms, native bulbs
- Mid-season: borage, phacelia, clovers (white/red), lavender, oregano, sunflowers, cosmos
- Late: goldenrod, asters, sedum, late-blooming native asters
- Herbs: dill, fennel, thyme, oregano, borage — great for tiny solitary bees and hoverflies. For best results, substitute regionally appropriate native species; check your regional extension or Xerces/USFWS plant guides for localized lists. (US Forest Service, Southern Living)
Common farmer concerns (and quick answers)
- Won’t flowers attract pests?
Some companion flowers do attract herbivores, but they also attract predators and parasitoids. Thoughtful placement and IPM minimize risks — many farmers report net benefits. (SARE) - “I don’t have land to spare.”
Even small strips, such as cover crops or planting herbs in field corners, can have measurable benefits for nearby crops. Scale what you can and expand over time. (North Carolina Field and Family) - “Bees will sting my workers.”
Most wild bees are non-aggressive; stings can be minimized by timing worker activities and avoiding disturbances to their nests. Educating staff about pollinator behavior helps. (U.S. Fish and Wildlife Service)

FAQs
Q1: Will flowers attract pests to my crop?
A: Some companion flowers may attract herbivores, but they also draw predators and parasitoids. Thoughtful placement, trap cropping and IPM minimize risks — most research and farmer reports show a net benefit for pollination and pest control. SAREXerces Society
Q2: How much land should I dedicate to pollinator habitat?
A: Start small — 2–5% of farm area as field margins, strips, or hedgerows can produce measurable pollination benefits for adjacent crops. Expand as you see benefits. SARE
Q3: Are most native bees ground-nesters?
A: Yes — many estimates show a large majority of wild bees nest in the ground (commonly cited figure ~70%), so set aside undisturbed, bare-soil patches. AgAmerica
Q4: When should I avoid spraying pesticides?
A: Avoid broad-spectrum pesticides during bloom and apply treatments at evening when pollinator activity is low. Prefer spot-treatments and IPM tactics. USDA
Final thought
Rebecca Vittetoe
I’m Rebecca Vittetoe, a field agronomist working with farmers through Iowa State University Extension.
Most of my time is not spent in an office—it’s spent in the field. I work directly with farmers, crop scouts, and ag professionals to solve real problems they face every season. From pest pressure to nutrient issues, I focus on what is actually happening in the field—not just what is written in books.
Over the years, I’ve learned that good farming decisions come from a mix of research and real-world experience. That’s what I try to bring into everything I do.
At toagriculture.com, I share simple, practical insights from the field:

What works—and what doesn’t
My focus areas include crop management, pest management, soil health, and cover crops. I’m especially interested in helping farmers improve productivity while keeping their farming systems sustainable.
Agriculture is always changing. My goal is to make that change easier to understand—and easier to apply in the field.
