Overview

About This Region

The Lake Erie Lowland, Canada’s southernmost ecoregion, boasts one of the warmest climates and is part of the most floristically diverse ecozone. Characterized by fertile soils and historically rich mixed/deciduous forests, it harbors a very high richness of species of conservation concern, including over 130 national species at risk. However, extensive cropped land and significant urban development pose challenges to pollinators, limiting habitat and floral resources despite the region’s biodiversity potential. This area, stretching from Windsor to Toronto, is critical for conservation efforts.

What shapes this region

Climate pattern

  • Lake influence can soften temperature swings and shift seasonal timing.
  • Microclimates (small local weather differences) are common—sunny south-facing yards, windy lakeside sites, and sheltered urban courtyards can behave very differently.
  • Soil moisture can range from dry, sandy spots to heavier, wetter ground depending on location and past land use.

Why pollinators matter here

  • Pollinators support wild plants and many garden and farm crops.
  • Urbanization and intensive land use can reduce continuous flowering and nesting sites.
  • Native plant patches help reconnect fragmented habitats.
  • Pesticide exposure and “too-tidy” landscapes can limit survival, especially for native bees.

Seasonal timing

Planting seasons

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

Seasonal timing

  • Early spring: Focus on early-blooming natives and leaving last year’s stems/leaves in place a bit longer.
  • Late spring to early summer: Prime time for planting many perennials and adding a “mid-season” bloom backbone.
  • Summer: Water new plantings during dry spells; add heat-tolerant bloomers to prevent gaps.
  • Late summer to fall: Great for planting perennials in many sites; prioritize late-blooming natives for migrating insects.

Quick seasonal checklist

  • Plant in clusters (3–7 of a kind) so pollinators can find flowers easily.
  • Aim for something blooming from spring through fall.
  • Keep a small area undisturbed for nesting and overwintering.
  • Use mulch carefully—leave some bare soil and avoid smothering stems/crowns.

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 emergeLeave stems and leaf litter in place a bit longer; plant early-blooming natives; avoid spring pesticide “cleanup” treatments
SpringSteady bloom; nesting materials and sitesAdd a mix of spring flowers; keep some bare, well-drained soil; provide shallow water with stones for landing
SummerReliable nectar during heat; shade/water; diverse flowersPlant drought-tolerant natives; water new plants during dry spells; keep blooms coming with mid-season species
Late summer/fallHigh-energy nectar; late pollen; overwintering prepPrioritize late bloomers (goldenrods/asters where appropriate); leave seedheads; reduce mowing and deadheading
WinterShelter from cold/wet; undisturbed nestingLeave stems standing; keep leaf litter under shrubs; avoid heavy fall “tidying” that removes cocoons and nests

Seed mix concept

A Billion Small Steps Seed mix

A simple way to plan a pollinator patch is to think in three layers:

Spring starter

Spring starter: early bloomers that help the first emerging bees.

Summer bridge

Summer bridge: reliable mid-season flowers that carry pollinators through the busiest months.

Fall finisher

Fall finisher: late-season flowers (often asters/goldenrods in this broader region) that fuel end-of-season bees and migrating insects.
