Overview

About This Region

The Maine/New Brunswick Plains and Hills region is vital for diverse pollinators, including bees, butterflies, and bats. Factors like habitat loss due to development and changes in agriculture, pesticide use, and climate change significantly impact these species. Conserving the region’s forests and wetlands, promoting native plant diversity, and reducing chemical use are crucial steps for supporting healthy pollinator populations and the local ecosystems they sustain.

Why pollinators matter here

  • Early-season flowers are critical for emerging native bees.
  • Late-season blooms help pollinators build energy for migration or winter survival.
  • Diverse native plants support a wider range of native insects than lawns alone.
  • Nesting habitat (bare soil, stems, leaf litter) is often missing in “tidy” yards.

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 “bridge” blooms.
  • Summer: Water new plantings during dry spells; add container flowers for quick nectar.
  • Late summer to fall: Great for planting many perennials and shrubs; prioritize late-blooming flowers.

Quick seasonal checklist

  • Add at least 3 bloom windows (early, mid, late).
  • Plant in clumps (easier for pollinators to find).
  • Keep one area messy on purpose (stems, leaves, and some bare soil).
  • Avoid pesticides—especially on flowering plants.

Yearly needs

Pollinator calendar

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

Late winter/early springEarly nectar/pollen; safe emergence sitesLeave leaf litter and stems a bit longer; add early-blooming native plants; provide a shallow water dish with stones
SpringSteady bloom; nesting sites (soil, stems, cavities)Plant a mix of spring bloomers; keep a small patch of bare, well-drained soil; avoid pesticide use
SummerReliable nectar/pollen; water during heat/dry spellsAdd mid-summer “workhorse” flowers; water new plantings; plant in sunny clumps
Late summer/fallHigh-energy nectar; seeds and shelter prepPlant late bloomers; avoid cutting everything back; let some plants go to seed
WinterOverwintering shelter (stems, leaf litter, soil)Leave stems standing; keep some leaves under shrubs; delay major cleanup until spring warms

Seed mix concept

A Billion Small Steps Seed mix

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

Spring starter

Spring starter: Early flowers (and flowering shrubs) that help pollinators as they emerge.

Summer bridge

Summer bridge: Reliable mid-season blooms that keep food available through the busiest months.

Fall finisher

Fall finisher: Late-season flowers (like asters and goldenrods) that help pollinators fuel up before winter.
