Each September, Milwaukee and Mequon become part of one of nature’s most awe-inspiring journeys: the monarch butterfly migration. These vibrant pollinators travel thousands of miles to their wintering grounds in Mexico, and Southeastern Wisconsin plays a critical role in helping them get there.
Whether you have a sprawling backyard in Mequon or a compact garden in Milwaukee’s East Side, your landscape can offer vital rest stops, fuel sources, and safe passage for migrating monarchs. Here’s how GardenScapes helps homeowners turn their yards into monarch-friendly havens.
Why Monarchs Need Our Help
Monarch populations have declined sharply in recent decades due to habitat loss, pesticide use, and climate change. Their migration is physically demanding, and without access to nectar-rich plants and safe resting zones, many butterflies won’t survive the journey.
Milwaukee County and Ozaukee County lie directly along the monarch’s central flyway. That means local gardens can make a measurable difference.
Top Ways to Support Monarchs in September
1. Plant Late-Season Nectar Sources
Monarchs need energy-rich nectar to fuel their flight. In Southeastern Wisconsin, the best fall bloomers include:
- Goldenrod (Solidago spp.)
- New England Aster (Symphyotrichum novae-angliae)
- Sedum ‘Autumn Joy’
- Joe-Pye Weed (Eutrochium spp.)
These native plants thrive in Mequon’s clay soils and Milwaukee’s urban beds alike, offering bold color and butterfly appeal.
2. Leave Milkweed Standing
While monarch caterpillars feed exclusively on milkweed earlier in the season, mature plants still serve as wayfinding markers and shelter. Avoid cutting back:
- Common Milkweed (Asclepias syriaca)
- Swamp Milkweed (Asclepias incarnata)
- Butterfly Weed (Asclepias tuberosa)
GardenScapes recommends leaving milkweed intact until spring cleanup to protect overwintering insects and seed dispersal.
3. Skip the Sprays
Even organic pesticides and herbicides can harm butterflies and pollinators. Instead:
- Use manual weeding or mulch to suppress unwanted growth
- Encourage beneficial insects like ladybugs and lacewings
- Choose integrated pest management strategies
GardenScapes offers eco-friendly garden maintenance packages for Mequon and Milwaukee clients who want a safe, pollinator-friendly yard.
4. Create Rest Stops and Shelter
Monarchs need places to land, hydrate, and hide from wind. Add:
- Flat stones for sunbathing
- Shallow water dishes with pebbles
- Dense shrubs or ornamental grasses for wind protection
Even small additions can turn your garden into a monarch oasis.

Supporting monarchs isn’t just good for butterflies—it’s good for biodiversity, soil health, and community pride. GardenScapes helps Mequon and Milwaukee homeowners design landscapes that are beautiful, functional, and ecologically responsible.
