Overview

About This Region

The Eastern Corn Belt Plains (Ecoregion 8.2.4) is characterized by rolling till plains, historically covered by oak-hickory forest and prairie. While largely agricultural today, protecting and enhancing native pollinator habitats—especially amidst widespread farming—is crucial for supporting species like native bees, which require foraging and nesting sites. Factors such as land use, soil characteristics, pesticide use, and the presence of diverse native flora (such as those adapted to its thick drift deposits and varied soil types) directly impact pollinator health and populations in this region.

Why pollinators matter here

  • Pollinators support wild plants that hold soil, feed birds, and keep ecosystems resilient.
  • In heavily managed landscapes, habitat can be fragmented—small patches help connect the dots.
  • A longer season of blooms helps pollinators find food from spring emergence through fall.
  • Nesting and overwintering sites are often the missing piece in “tidy” landscapes.

Seasonal timing

Planting seasons

Timing varies by microclimate; use this as a flexible guide.

Seasonal timing

  • Early spring: Plan, prep beds, and start with early-blooming natives (or plugs) when soil is workable.
  • Late spring to early summer: Main planting window for many perennials; keep new plants watered until established.
  • Summer: Add heat-tolerant bloomers and focus on watering, mulching lightly, and weeding.
  • Late summer to fall: Great for planting many perennials; also a key time to add late-blooming flowers.
  • Winter: Observe where snow/drifts, shade, and runoff collect; plan next year’s bloom sequence.

Quick seasonal checklist

  • Choose at least 3 species: one early, one mid, one late bloomer.
  • Add one clump (not just one plant) of a reliable native flower.
  • Leave a small patch of bare, well-drained soil for ground-nesting bees.
  • Keep some stems/leaves standing until spring warms up.

Yearly needs

Pollinator calendar

What pollinators need throughout the year, and what to do about it.

Late winter / early springEarly nectar/pollen; safe places to emergePlant or plan for early bloomers; avoid spring yard “cleanups” that remove shelter too soon
SpringSteady food; nesting sitesAdd a few native perennials; leave some bare soil; keep a shallow water source available
SummerContinuous bloom; water during hot/dry spellsFill bloom gaps with mid-summer natives; water new plantings; avoid all pesticides
Late summer / fallHigh-energy nectar; late pollen; overwintering prepPlant late bloomers; leave seedheads and stems; reduce mowing and trimming
WinterShelter and protectionLeave stems, leaf litter, and natural corners; plan next season’s bloom sequence

Seed mix concept

A Billion Small Steps Seed mix

A simple way to plan (or buy/build) a seed mix is to think in three layers so something is always blooming:

Spring starter

Spring starter: early bloomers that help pollinators as they emerge and begin nesting.

Summer bridge

Summer bridge: mid-season flowers that keep food available through the hottest, busiest months.

Fall finisher

Fall finisher: late-season asters/goldenrods and other fall bloomers that help pollinators fuel up before winter.
