Here at Rosborough Partners we take advantage of these winter months to hone our skills with training and education. Our teams are currently going through hands-on training and attending seminars to learn the latest products, tools and techniques. Staying on top of technology and innovation elevates the level of service we provide and reflects back in your stunning sites.

This month our staff is attending a wide variety of training to gain skills and obtain or renew certification on an array of beneficial landscape products and services. Our goal continues to be providing the highest level service to our clients, and these courses help to achieve that end.


We hope you are having a great week. As we move further into autumn, our team is planning for winter and how to best service your landscape throughout the season. Based on the past few years, we anticipate large temperature swings and elevated levels of precipitation that leave behind winter storm damage and debris, along with potential major snow melts.

Because of the pattern of the past few years, we are offering winter landscape policing services for your property. These services can include, but are not limited to:

  • Fallen tree limbs and broken branches
  • Hanging/hazardous branches or trees
  • Shrub damage
  • Garbage blown onto property
  • Parking lot and island debris
  • Shoreline clean up

Winter policing packages can be customized by service needs and frequency based on your specific requirements, and services are available on a Time & Materials basis. Our staff will work with you to formulate a plan that mitigates the effects of winter’s damage and that meets your needs and budget.

If you have any questions or would like to request winter policing services, please contact our main office at 847/549-1361, Monday-Friday 8:30am-5:00pm.

Plant Health Care

As everyone is aware, we have had a record breaking start to the season.  Record snow in April, record rain in May, and a wet start to June.  These extreme weather conditions have resulted in an increase in the plant disease and pest issues listed below, which we are diligently monitoring on client sites. In particular, Doublefile Viburnum and Burning Bush were hit hard, and many have not come back this season.  The Rosborough team is inspecting for these plant health care concerns for our clients and providing recommendations as needed.

Red thread on turf
Dollar spot on turf
Mites on burning bush
Leaf beetle on viburnum
Scale on magnolias and euonymus
Leaf miner on boxwoods and hawthorn trees

Our teams are working hard to apply the appropriate treatments for each of these issues, and in many cases re-applying due to rain.

If you believe you have a matter that requires attention or diagnosis, please contact our office: 847-549-1361 Monday-Friday 8:30am-5:00pm.

Product Replacement For Weed Control


We hope this communication finds you well.  As many of you are probably aware, there have been reports in the media regarding Roundup non-selective weed killer, and in particular the active ingredient glyphosate.  We are aware of the reports and are paying close attention to the court case in San Francisco.

Glyphosate is the most commonly used herbicide and has been used safely for more than 40 years by landscape professionals around the world. It also continues to be approved by the EPA, and studies have shown when properly applied is safe and effective.  However, we understand there could be concerns from media coverage.

Therefore, effective August 1, Rosborough Partners will be switching to a non-selective weed killer that is a non-glyphosate alternative and dropping Roundup from our inventory.  This new product is FDA regulated, safe to use, and we believe its effectiveness will be comparable.

If you have any questions or requests for service, please contact your Account Manager or Plant Health Care professional directly, or call our office:847/549-1361 Monday-Friday 8:30am-5:00pm.

With the extreme cold blowing through the Chicago area this week, please consider the following safety tips:

* Avoid prolonged time outdoors. If you must, dress in layers. Cover any exposed areas of skin – including the face, neck, hands, etc.

* Know the risk, signs and symptoms of hypothermia
– Adults: Shivering, exhaustion, confusion, fumbling hands, memory loss, slurred speech and drowsiness.
– Children & Infants: Bright red, cold skin and very low energy.

* Know the risk, signs and symptoms of frostbite
– A white or grayish-yellow skin area
– Skin that feels unusually firm or waxy
– Numbness
– At the first sign of redness or pain in any skin area, get out of the cold or protect any exposed skin – frostbite may be beginning.
– A victim of frostbite is often unaware of frostbite until someone else points it out because the frozen tissues are numb.

If you experience of hypothermia or frostbite, seek immediate medical attention. Do not wait!

Other Safety Reminders:

* Have an emergency kit ready in your car – blankets, flashlights, water, snacks and jumper cables are a few of the essentials.

* Keep your cell phone on a full charge.

* Keep your car’s gas tank full or fill it when the gauge hits the ½ tank mark.

* Don’t overexert yourself while shoveling snow. Call 9-1-1 if you experience chest pain.

* Extreme cold is dangerous for pets too. Keep your pets indoors as much as possible.

Finally, consider the following safety tips when using supplemental heat sources such as space heaters:

* Ensure that all combustible items are kept away from the unit

* If using a kerosene heater, make sure it’s in a well-ventilated area.

* Do not run your stove or oven to generate heat

* Homes with high-efficiency furnaces should make sure the venting to the outside of the home is clear and not snow covered.

Bottom line, please extreme caution during these dangerous conditions and do everything that you can in order to keep yourself and your family safe.

Good Morning,

We want to inform you that instances of Fire Blight have come to our attention, a plant health care issue that affects ornamental trees such as Pear, Crabapple and Alder, and is brought about by the record precipitation and extreme temperature and humidity swings we have been experiencing. This unique set of weather circumstances creates an ideal environment for Erwinia amylovora, the bacterium responsible for Fire Blight, and can cause critical damage fairly quickly which is incurable.


Fire Blight affects ornamental trees, and presents as a tan or reddish fluid seeping from discolored branches or trunk cankers combined with curled and/or browning foliage near the infection site.


We recommend careful pruning out of diseased wood in accordance with horticulture practices, including sterilization of tools between cuts. Because there is no cure for Fire Blight, severely affected trees may require removal.

Our plant health care professionals will be looking for signs of Fire Blight at client sites, and will make contact regarding treatment if any issues are identified.

Please contact our Plant Health Care Department (847-549-1361) if you have any questions or believe you have infected trees.

And The Award Goes To…


Rosborough is excited to have won an award for our work on the Shakespeare Garden at Northwestern University. Below is the press release announcing this wonderful honor.

Rosborough Partners (RP) has won the Gold Award from the Illinois Landscape Contractors Association (ILCA) for their construction work on the landmark ‘Shakespeare Garden’ on the picturesque Northwestern University campus in Evanston. This landscape was in collaboration with Hitchcock Design Group, and the award recognizes Rosborough Partners for their superior construction in updating the garden while still honoring its long-standing history. Initially commissioned and still controlled by the Garden Club of Evanston, the design of the Shakespeare themed garden was originally done in 1913 by Jens Jensen, the celebrated landscape architect made famous for his “prairie-style” designs. In restoring the garden back to its original splendor, Rosborough’s attention to detail included incorporating elements from the Elizabethan era for visitors to feel transported back in time as they stroll through the garden.


“Partnering with Northwestern University and Hitchcock Group to rehabilitate this historic garden has truly been an honor,” said Phil Rosborough, President of Rosborough Partners. “The garden was time worn and in need of rejuvenation to restore its life and character, so our team worked with a committee to research plants and architectural details from Shakespeare’s boyhood home to ensure accuracy, such as fragrant heirloom roses and clematis-filled wooden obelisks. Our goal was to invite visitors to slow down and immerse themselves in Shakespeare’s world, so we also updated the flagstone sitting area for guests to literally stop and smell the roses.  We are humbled by the recognition and thrilled to receive this award.”


Rosborough Partners is one of Chicagoland’s premier full-service landscape architecture firms, offering a full array of residential and commercial garden and landscaping services to help you transform your outdoor space into a warm and welcoming part of your life. Their remarkable work on this historic garden was honored February 1, 2018 at the iLandscape Show, ILCA’s Midwestern event for landscape professionals. This award, in addition to two others this year, marks the 16th ILCA award Rosborough Partners has received for excellence in landscape design, construction and maintenance, emphasizing their commitment to service and stewardship, and an overall superior client experience.

Rosborough’s honor is awarded by the ILCA, whose mission it is to enhance the professionalism and capabilities of members by providing leadership, education, representation, and services, while promoting environmental awareness and the value of the landscape industry.

Chicago Flower & Garden Show

And what a wonderful morning it is. The staff is busy with excitement preparing our exhibit for the Chicago Flower & Garden Show at Navy Pier, March 14-18 … planning, designing, and building … telling our story through this very special presentation. Our ‘Garden Trilogy’ display, in keeping with the show’s FlowerTales theme, is inspired by Bernie’s Book Bank and their important ‘Books For A Better Life’ mission to bring quality reading material to under privileged children.
We will reveal some of the book-inspired surprises in our garden later, but in the meantime, enjoy these Flower & Garden Show photos from previous years to give you an idea of the spectacular displays being created for everyone’s enjoyment.
To anyone that has grown tired of winter’s tight hold, we would persuade you to attend the show for a refreshing jump on spring, complete with colorful blooms, heady fragrance, and most importantly … fantastical gardens that bring to life your cherished childhood imaginings. We look forward to seeing you there!  For tickets and information:
For those looking for a special night out that honors the crucial work of this year’s beneficiaries, we encourage you to attend the Flower & Garden Show charity night, Tuesday, March 13, for an evening of horticulture inspired fashion, delicious food, and aromatic spring flowers.
