Celebrating Arbor Day in Milwaukee's North Shore

Spring is the perfect time to dig in and give back — literally. Arbor Day, celebrated nationally on the last Friday of April, is a reminder of something easy to overlook: trees do an enormous amount of heavy lifting for our communities. They clean the air, manage stormwater, cool neighborhoods, shelter wildlife, and make the places we live more beautiful and livable.

Wisconsin's urban tree canopy faces ongoing pressure from development, invasive pests like the emerald ash borer, and aging street trees. Communities across the greater Milwaukee area — from Bay View to Grafton — have lost significant tree cover in recent decades. Arbor Day is a chance to start turning that around, one tree at a time.

Locally, trees along streets and in parks help reduce the urban heat island effect, lower energy costs for homeowners, and keep stormwater out of the sewer system. In a region prone to heavy spring rain, that last benefit alone makes tree planting one of the most practical things a community can do.

Whether you're heading to a local event or planting something new in your own backyard, here's your guide to celebrating Arbor Day 2026 in the Milwaukee area.

North Shore Arbor Day Events and Activities

National Arbor Day falls on Friday, April 24, 2026. Wisconsin observes Arbor Day on the same date — the last Friday in April — making this a great long weekend opportunity to get outside and get your hands dirty.

The Village of Fox Point will host its annual Arbor Day celebration on Friday, April 26 at 1:45 pm. Residents are invited to the 56th Annual Arbor Day Celebration held at Stormonth School.  The program includes a tree dedication, distribution of Hackberry Tree seedlings and presentation of the Tree City Flag by the DNR, recognizing Fox Point’s commitment to urban forestry.

In Bayside, residents have the opportunity to participate in the Bayside Adopt-a-Tree program. This initiative allows residents to purchase selected tree species for planting in the public right-of-way or on their private property. For trees planted in the public right-of-way, the cost is $300 and includes the tree, planting, mulching, and initial watering. Residents within the 2025 road project area may qualify for a reduced cost of $250 for right-of-way trees. For trees planted on private property, the cost is $350 and includes only the tree.

Shorewood will be hosting its Arbor Day Celebration on Friday, April 26th at 10 am at River Park. The Department of Public Works (DPW) Forestry division will be planting new trees, an effort supported in part by a grant from the Shorewood Men's Club. The entire community is invited to attend this event, which also marks Shorewood's 29th consecutive year as a Tree City USA.  

Mequon’s annual Arbor Day celebration is taking place Sunday, April 28, from 1 p.m. - 3 p.m. at River Barn Park. Last year, nearly 1,500 trees were distributed. Again this year, there will be raffles, a planting demonstration and numerous local nature-driven organizations will be on hand inside the pavilion. Don’t miss the forestry equipment that will be on display and rock painting for children! Free trees and shrubs will be given out (3 per person), while supplies last. Seedlings available this year include Black Cherry, Black Maple, Northern Red Oak, White Paper Birch, White Pine, White Spruce, American Elderberry, Hazelnut, Red Twig Dogwood, and Nannyberry.

Tree planting in Shorewood

One of the best ways to mark the day is by showing up and pitching in. The Village of Bayside is hosting an Arbor Day Celebration on April 24, 2026 starting at 9 a.m. at Ellsworth Park. The event features tree planting demonstrations, and attendees are encouraged to participate in the planting process themselves — not just watch.

It's a hands-on, community-oriented morning that's great for families, gardeners, and anyone who wants to do something meaningful with a few hours on a Friday. Trees for the event are generously donated by Bayside Garden Center.

Ellsworth Park is located in the Village of Bayside, just off Brown Deer Road. Check the Village of Bayside's website or social media for any updates closer to the date.

How to Get Free or Discounted Trees

You don't need to wait for a community event to plant a tree. Several programs offer free or low-cost trees to Milwaukee-area residents each spring.

The Wisconsin Department of Natural Resources offers a Seedling Sale each year through its nursery program, with bare-root seedlings available at very low cost for Wisconsin landowners. Species include native oaks, maples, pines, and shrubs ideal for wildlife habitat.

Many Milwaukee-area municipalities also run their own tree programs. The City of Milwaukee's forestry division periodically offers free street tree planting for eligible properties. Suburban communities including Shorewood, Whitefish Bay, and Glendale have partnered with programs like Tree Planting in Our Neighborhoods (Trees PLANT) to distribute free trees to residents. Check your village or city website in early spring — these programs often have limited availability and go fast.

The Arbor Day Foundation's online store also ships trees to Wisconsin addresses, with frequent sales that bring prices down to just a few dollars per tree.

Best Trees to Plant in the Milwaukee Area

Choosing the right tree for your yard makes all the difference. Native species tend to require less maintenance and provide the most ecological value. Some top picks for southeastern Wisconsin include:

Bur Oak — incredibly durable, drought-tolerant once established, and a keystone species for native insects and birds. Excellent for larger yards.

Sugar Maple — a Wisconsin classic, stunning fall color and great shade. Thrives in well-drained soil.

River Birch — beautiful multi-stem form, tolerates wet areas better than most trees, and resistant to the birch borer that troubles white birches.

Serviceberry (Amelanchier) — a smaller ornamental tree perfect for tight spaces, with white spring blooms and berries that birds love.

Swamp White Oak — another excellent native that tolerates the clay-heavy soils common throughout Milwaukee's North Shore suburbs.

If you're replacing an ash tree lost to emerald ash borer, consider diversifying with a mix of species so your yard isn't vulnerable to any single pest in the future.

Tips for Planting a Tree Successfully This Spring

Even the healthiest tree can struggle if it's planted incorrectly. A few basics go a long way.

Dig the hole wide, not deep. The hole should be two to three times the width of the root ball but only as deep as the root ball itself. Planting too deep is one of the most common tree-killing mistakes.

Keep the root flare above grade. The spot where the trunk widens into the roots should sit at or slightly above the soil surface.

Mulch, but don't volcano. A 2–3 inch ring of mulch helps retain moisture and regulate soil temperature — but piling it up against the trunk invites disease and pests. Keep mulch a few inches away from the bark.

Water consistently for the first two years. Newly planted trees need about an inch of water per week, especially during dry spells. A slow trickle for 30 minutes once or twice a week beats a quick blast from a hose.

Skip the fertilizer for the first year. Let the tree focus on root establishment before pushing new growth.

Connecting with Tree Experts

Local nurseries and garden centers play a crucial role in supporting the urban forest by providing residents with healthy trees and expert advice. Staff at these establishments possess valuable knowledge about which tree species are best suited for the local climate and soil conditions of the Milwaukee North Shore. They can offer guidance on selecting native trees and provide specific instructions on proper planting techniques and ongoing care requirements. Visiting a local nursery allows residents to not only purchase high-quality trees but also to tap into a wealth of horticultural expertise that can significantly contribute to the success of their tree planting endeavors.  

The Wisconsin Department of Natural Resources (DNR) is a key state agency that provides a wealth of information on forestry-related topics. Their website offers guidelines on tree planting , details about Arbor Day in Wisconsin , and information on various urban forestry programs. The DNR also plays a central role in recognizing communities for their urban forestry efforts through the Tree City USA program. Residents can find a wide range of educational materials and practical advice on the DNR's website to support their tree planting and care endeavors.  

The local county UW-Extension office serves as another excellent resource for residents. As part of the University of Wisconsin system, the Extension provides research-based information and advice tailored to the specific conditions of the region. They can offer guidance on tree selection, planting techniques, and ongoing care practices suitable for the Milwaukee area's climate and soil types. The UW-Extension also provides resources on understanding hardiness zones and may have specific publications relevant to tree care in Wisconsin, such as the "Guide to Selecting Landscape Plants for Wisconsin" (A2865). Contacting the local UW-Extension office or exploring their website can connect residents with valuable expertise and resources.  

On a national level, the Arbor Day Foundation is a prominent non-profit organization dedicated to inspiring people to plant, nurture, and celebrate trees. Their website is a comprehensive source of information on all aspects of tree care, including guidance on tree selection, planting best practices, and tips for maintaining tree health. The Arbor Day Foundation also promotes Arbor Day activities and offers various programs to support tree planting and conservation efforts across the country. Residents can find a wealth of educational materials and opportunities for involvement through this organization.  

Finally, while the North Shore communities are distinct from the City of Milwaukee, the Milwaukee Forestry Division is the entity responsible for managing street trees and green spaces within the city. Their website may contain general information on tree care practices and tree species suitable for the broader Milwaukee region, which could be a useful reference for North Shore residents seeking general guidance on urban forestry.  

Trees are an invaluable asset to the Milwaukee North Shore communities, contributing significantly to the environment, the aesthetic appeal of neighborhoods, and the overall quality of life for residents. Arbor Day serves as an important annual reminder of the numerous benefits trees provide and encourages active participation in their care and expansion. By understanding the best times and methods for planting, adopting effective ongoing care practices, and taking advantage of local programs and resources, residents can become integral stewards of their urban forest.

More Ways to Celebrate Arbor Day

Beyond planting, there are other meaningful ways to get involved this Arbor Day season.

Take a tree ID walk. Milwaukee County Parks, the Urban Ecology Center, and local nature centers like the Schlitz Audubon Nature Center offer guided nature programming throughout spring. Check their calendars for tree or plant identification walks.

Volunteer with a local conservation group. Organizations like Sixteenth Street Community Health Services, Groundwork Milwaukee, and Friends of Milwaukee's Rivers regularly recruit volunteers for habitat restoration and tree planting projects across the metro area.

Teach kids about trees. The Arbor Day Foundation's website has free classroom and family resources. Even a backyard scavenger hunt identifying tree species is a great low-key activity for younger kids on a spring afternoon.

Support urban forestry advocacy. Milwaukee is a Tree City USA community, and your local parks and forestry departments rely on public support and funding to maintain and expand the urban canopy. Attending city council or village trustee meetings, or simply submitting comments in support of tree planting budget items, makes a real difference.

Arbor Day is one of those holidays that rewards showing up. Whether it's a few hours at Ellsworth Park in Bayside or a new tree in your own front yard, the work you do this April will be growing for decades. That's a pretty good return on an afternoon.
