The Village of Glen Ellyn places great pride in the trees that enhance its beauty, even deriving its name from the trees that surround Lake Ellyn. For over 25 years, the Village has been named a Tree City USA for its commitment to enhancing and maintaining trees located within the Village. 
The Public Works Department directs programs to enhance the health and diversity of trees located on public grounds. Glen Ellyn features a variety of spectacular trees within the Village.  To learn more about the Village’s forestry programs or others, please visit the links below.
Parkway Trees
Trees planted on the parkway (usually the area between the street and the sidewalk) are the property of the Village of Glen Ellyn.  If you are interested in learning more about parkway tree plantings please view the information below.

More Parkway Tree Information

Parkway Reforestation Program
Parkway trees are planted through one of the following programs:

The Village selects the species and replaces the tree in the order in which it was removed as part of its annual tree replacement program. There is no direct cost to the resident.




After calling the Village Public Works Department at 630-469-6756 and securing an approved permit, residents may hire a qualified contractor to plant a tree in the parkway at your own expense.   Replacement can be immediate with this option.

Parkway Tree Maintenance & Removal
Trees planted on the parkway (usually the area between the street and the sidewalk) are the property of the Village of Glen Ellyn. If you have concerns about the health or maintenance of a parkway tree, please call the Public Works Department at 630-469-6756 between 7:00 a.m. and 3:30 p.m.  A permit is required to plant or perform any maintenance on parkway trees.   There is no charge for these permits.


Tree & Yard Maintenance

Private Tree Maintenance & Removal
Tree care companies must be registered to do any tree maintenance or removals in the Village, whether on private or on public property. There is no charge for this registration.  A permit is not required to remove a tree from private property; however, by ordinance, removals by tree care companies must be reported within seven days after the removal is completed. 
Weed Ordinance and Private Tree & Shrub Pruning
Village Code requires that weeds be mowed to less than 8 inches. Also, residents are asked to trim private property tree limbs and shrubs that overhang sidewalks or parkways so they do not pose safety hazards. If parkway trees need to be trimmed, please call the Public Works Department at 630-469-6756.
Mulching Techniques
Mulching is one of the most beneficial things that you can do to keep your trees healthy. If done incorrectly, however, it can also lead to the death of your tree. Mulching increases soil organic matter, water-holding capacity and nutrient availability. It also acts as an insulator, buffering the soil from rapid temperature changes. It helps control weeds and protects the trees’ trunk from being hit by the lawn equipment.
To properly apply mulch, place a 2-4 inch layer of mulch in the shape of a saucer at least two to three feet out from the trunk of the tree. Do not pile the mulch up against the trunk of the tree. Mulch mounded up against a tree’s trunk (volcano mulching) can cause bark rot, which makes the tree vulnerable to disease and insect problems and may even lead to death of the tree. For more information, please contact Public Works at 630-469-6756.
Lawn and Watering Techniques
The Illinois Department of Natural Resources mandates that water conservation measures be undertaken between May 15 and September 15.  As such, Village Code restricts lawn watering year round. Odd numbered addresses may water on odd numbered days and even numbered addresses may water on even numbered days.  Watering hours are from 5 a.m. to 8 a.m. and from 7 p.m. to 11 p.m.   No watering is allowed between the hours of 8 a.m. and 7 p.m.  Notwithstanding the foregoing, freshly planted or newly seeded lawns may be watered daily between 1:00 p.m. and 4:00 p.m. for a period of 30 days.
Gator bags are a slow-watering system for newly planted trees – and trees that have been planted within the last three years. These bags, which fit around the base of the tree, are a convenient and effective way to slowly water your tree over a longer period of time.  Gator bags can be purchased at any lawn and garden center. 


Infestations threaten the health of the Village’s trees. The Emerald Ash Borer has killed millions of trees in neighboring states. Gypsy Moths, as well, can defoliate a tree in a matter of days. Both of these insects have been spotted in or near Glen Ellyn. In addition, Oak Wilt has been found in Glen Ellyn, a fungus which can kill many species of oak trees. The Village maintains a diversified stock of public trees to avoid a significant loss of tree species to threats old and new. Use the following information to help prevent the spread of these infestations within our community.

Emerald Ash Borer
The Emerald Ash Borer (EAB) is a small, green insect that has killed millions of ash trees in the United States.  EAB was confirmed in Glen Ellyn in March of 2009
EAB Frequently Asked Questions
Gypsy Moths
The Gypsy Moth is a leaf-eating insect that feasts on trees and shrubs. In large populations, it is capable of stripping plants bare, leaving them vulnerable to secondary insect and disease attacks. Gypsy Moth caterpillars can defoliate trees in a matter of days, leading to stress and susceptibility of death if it occurs over a period of years. The woods bounded by Crescent, Roger, the railroad tracks and Park Plaza, and Lake Ellyn sections of the Village have had a heavy infestation of Gypsy Moths in recent years.
Evidence of a gypsy moth infestation comes in late spring and early fall. Tan or buff-colored egg sacks found on patio furniture, trees or houses may be evidence of an infestation.  If you suspect you have a gypsy moth infestation, please call Public Works at 630-469-6756 to report your location. You can also scrape off the egg sacs and drop them in soapy water, which will help to limit the number of eggs that hatch in the coming year. Visit for more information.
Japanese Beetle
What is eating my trees/shrubs and flowers?  It may be Japanese Beetle. These insects may cause negative or unsightly appearance of tree and flower leaves or petals in your vegetation.  Please visit the following websites for more information on Japanese Beetles.
Oak Wilt Disease
This disease has been found in the area East of the tracks and North of the Railroad tracks.  This is a serious disease that affects many species of oak trees.  Oak Wilt is caused by a fungus that invades the water conducting system of a tree and interferes with the normal water flow.
Spread of Oak Wilt - Oak Wilt moves from tree to tree in a variety of ways:  It usually occurs by root graft, with infected tree roots intertwining with a healthy tree.  The other ways are by insects carrying the fungus and boring into a healthy tree, animals and pruning tools.
Symptoms - Symptoms usually progress from the top of the tree downward.  Generally the leaves at the top of the tree turn a dull green, then tan, then wilt and start falling.  This can occur in late June to early July.  As the disease progresses individual leaves quickly discolor, taking on a bronzed appearance.  Leaves fall rapidly as the disease progresses.  Trees can defoliate within a few weeks of symptoms onset. 
Diagnosis and Management - There are two ways to contain the disease: 1) provide a root graft barrier by trenching between the infected tree and healthy trees, and 2) remove the infected tree as soon as possible.  To protect non-infected trees an arborist can inject a chemical that will help protect the healthy tree from the disease.
As a precautionary measure, no pruning of oak trees should occur between April and October.  The beetle that carries the fungus is attracted to freshly cut wood.  Any firewood from an infected tree that is kept must have the bark peeled off.
Control - There is chemical and mechanical control for healthy trees. 
Please watch for Oak Wilt symptoms in your neighborhood.  If you think a private tree may have symptoms contact the Public Works Department.
