In Elk Grove Village, we care about trees and the beautiful landscape that surrounds our community. We have published a variety of information below to help you and us take care of our community together. Please feel free to submit a service request if you cannot find the information that you are looking for or would like our specialized assistance.
Working Together to Keep Young Parkway Trees Healthy: Tree Watering Program
Thank you for your interest in the Village’s new parkway Tree Watering Program. This is a voluntary program available to residents who had a parkway tree replaced during previous year (for example: In 2020, trees planted in the Spring or Fall of 2019 are eligible for the program). The program provides a $25 credit on your water bill in exchange for assisting the Public Works Department by watering your parkway tree.
Public Works crews will place a tree bag on your tree. You will then need to add water to the tree bag twice per week. This is roughly the equivalent of 40 gallons of water over the course of the program.
Your $25 credit will appear on you water bill in September/October, after the program has completed.
To participate in the program contact the Public Works Department at (847) 734-8067 or fill out a request form online by clicking here.
How to Take Care of Your Young Parkway Tree Using a Tree Bag in Four Easy Steps
Step 1 - Public Works crews will install the tree watering bag on your young parkway tree. The bag installs easily, just place it at the base of the tree and zip it up.
Step 2 - Once installed, the tree bag will need to be filled with water. To find the opening, lift up on the manufacturer’s informational tag located at the top of the bag. Insert a standard garden hose and begin to fill with water.
Step 3 - Fill the tree bag approximately one-fourth full, and then pull up on the handles located at the top. Pull the bag up slightly off the ground and then set the bag back down. This will ensure that the bag sits flat at the tree base.
Step 4 - Once the tree bag is full, the water will drain out slowly over the next 8 to 24 hours. It will need to be filled twice per week, weather permitting. Do not fill more than twice per week or add any chemicals to the water (i.e. fertilizer). Keep watering the tree bag until mid-October, at which time Public Works crews will return to remove the tree bag.
Newly planted parkway tree require special care during their first few years. Our combined efforts will ensure proper establishment and healthy growth of the parkway tree.
Please note that the transplanting procedure is traumatic to a tree, and many trees may demonstrate symptoms of shock including withered leaves or leaf loss.
After trees are planted in the spring, the Public Works Department will normally add a tree watering bag in May or June. If the rainfall totals remain above average, the Public Works Department may elect to delay placing the bags until the weather dictates. The tree watering bags will be filled about once a week for the first year by our Public Works Department staff. Please do not water the tree during the first year as overwatering may be harmful to the tree.
The second year residents are encouraged to take part in our tree watering program. Residents are offered a $25 credit on their water bill to fill a tree bag once each week..
When the tree was planted, mulch was placed around the base of the tree. Mulch helps retain soil moisture and moderate temperature extremes that can affect root growth. The use of mulch also prevents damage from lawn mowers and string trimmers. Mulch volcanoes, decorative rock, and plastic weed barriers cause damage to young trees and should be avoided.
Lawn mowers and string trimmers need to be kept away from the trunks of trees. Repetitive damage to the bark can lead to the tree’s death. Also, careful application of weed treatments is advised. Spray drift and excessive use can cause severe damage to tree foliage and roots.
Transplant Shock - Transplant shock is fairly common in newly transplanted trees. Researchers have found that a tree can lose as much as 90% of its root system when it is removed from the nursery. This causes a great deal of stress on the plant as it is tries to reestablish itself. Approximately one year of recovery is needed for every inch of tree diameter. Water is probably the most important element in caring for new trees. Since a newly transplanted tree has not extended its roots into the existing soil, adequate moisture needs to reach the root ball.
Village parkway trees are trimmed within various sections of the community during the months of December through March. The trees are pruned to eliminate low hanging branches, remove dead or damaged limbs, and reshape the tree crown thus enhancing and preserving the tree’s health and appearance. The objectives of the trimming operation include the following:
• Allow sun light to penetrate the crown of the tree to promote new growth and strengthen existing limbs.
• Eliminate weak forks in tree stems and reduce the weight on support limbs.
• Reduce the possibility of future damage to the tree by high winds and storms.
• Maintain adequate visibility and vertical clearance for vehicle and pedestrian traffic.
Public Works crews perform low branch trimming operations and remove damaged high branches. A tree contractor is typically hired to perform high branch tree trimming operations during the winter season. All branches are mulched promptly after trimming and the mulch is utilized to maintain landscape beds at various Village locations.
After the trees are trimmed they may look barren until new Spring growth occurs. History has proven that proper tree trimming is vital in maintaining the appearance and health of our urban forest.
Cottony Maple Scale
Have you noticed a sticky substance on your cars, trees, homes and other areas of your property this summer? This sticky substance is caused by cottony maple scale. Cottony maple scale is primarily found on silver maples and boxelders but can also be found on other maples, white ash, hackberry, dogwood, beech, apple, oak, linden, elm, black and honey locust.
What is it?
Cottony maple scale is one of the largest and most conspicuous soft scale insects that attack ornamental plants. The overwintering form of the cottony maple scale is a small, brown, flattened 1/8 inch long scale attached to the bark of twigs and small branches. During the summer, the scale enlarges by secreting wax resulting in a body several times greater than the overwintering form. The immature scale is flat, oval shaped, and light yellow to green.
Is that popcorn in your tree?
Females produce white, cottony egg sacs that resemble pieces of popcorn on twigs. These scales also produce large amounts of liquid waste (honeydew) so leaves and anything else beneath the tree may be shiny and sticky.
Is the sticky substance dangerous?
No the sticky substance is not dangerous. The sticky substance, known as honeydew, is secreted by the insects after they ingest tree leaves and sap.
Why am I just now noticing the sticky substance?
Cottony maple scale is always present. However, in some years, the scale population increases above “normal” and becomes large enough to get noticed. Due to a long wet spring immediately followed by a hot dry summer the scale has become more pronounced this year. The dry weather has also caused the substance to become airborne and travel greater distances from the trees it originated from.
Why is the substance sometimes grainy and discolored?
Sometimes mold grows on the honeydew, which gives it a sooty appearance. Additionally, dust and other airborne particles will become stuck to the honeydew and make it appear discolored.

What is tar spot? Tar spot is a common, visually distinctive and primarily cosmetic fungal leaf spot disease. The Initial symptoms of tar spot are small yellowish spots that form on infected leaves. These spots may remain relatively small, or may enlarge over the growing season to roughly 3⁄4 inch in diameter. As tar spot progresses, the center of the infected area becomes raised and turns black. For more information click on the link: http://fyi.uwex.edu/hort/files/2014/11/Tar-Spot.pdf
Galls are abnormal growths on plants that can result from the feeding of living organisms such as bacteria, fungi, nematodes, insects and mites. For more information click the link: http://fyi.uwex.edu/hort/files/2014/11/Deciduous-Tree-Galls.pdf
Anthracnose is very common on many types of trees and shrubs. It often occurs on the leaves of ash and maple trees, causing blotchy-brown dead areas. For more information click the link: http://fyi.uwex.edu/hort/files/2014/11/Anthracnose.pdf
Chlorosis affects the leaves and turns them yellow, except for the veins, which remain green. In severe cases, turn brown and die. Symptoms can occur on isolated branches, or over an entire tree. For more information click on the link below: http://fyi.uwex.edu/hort/files/2014/11/Chlorosis_0.pdf
Verticillium is a disease that shows symptoms on individual branches that suddenly wilt and die. Affected branches may occur on one side of the tree or may be scattered throughout the tree.
