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 gardens.


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.


From all of us to all of you, best wishes for a Happy New Year!


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/evergreen damage
  • Garbage blown onto property
  • Driveway debris
  • Watering containers with live evergreens when temps are above freezing (if frost free bib is available on property)

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 our main office at 847-549-1361, Monday-Friday 8:30am-5:00pm.

Fall Decor And Landscape Services

It has been a wet but beautiful autumn so far as fall colors are beginning to appear. During this time we simultaneously celebrate the harvest and prepare your landscape for the upcoming winter. It is our goal and our pleasure to amplify the joy each season’s garden brings.

Plant Health Care

Our team will be performing the following services this week to ensure a beautiful, healthy landscape:

* Turf fertilization to promote strong root growth before winter

We don’t need the thermostat to tell us it is hot outside … just step out of the house. Like with people, plants must stay hydrated in extreme heat to retain good health. When temperatures climb into the 90’s it is important to watch for signs of dehydration in the garden, such as wilting, browning and leaves dropping. Irrigation systems offer the easiest method of ensuring sufficient moisture during the summer and can be adjusted as necessary, but alternatives are strategically placed soaker hoses and sprinklers. Turf can be left to go dormant with little or no long term damage, however, perennials, shrubs and trees, especially newly planted, can suffer and potentially perish if left unwatered. In addition, pots and annuals will need to be watched and watered more frequently. We want to make clients aware of the following industry guidelines:

Watering Guidelines
Annuals & Perennials – 1-2 hours twice a week, let top of soil dry without plant wilting.
Established Groundcover – 1 hour every 2 weeks.
Small Shrubs – soaker hose or slow trickle 1-2 hours per week.
Ornamental Trees & Large Evergreens – soaker hose or slow trickle 4 hours per week.
Lawns – Give new sod a good soaking 45-60 minutes daily. Sprinkle seed daily just enough to keep it moist. Established lawns need 1-1.5” of water per week, depending on sun exposure, or you can let go dormant.


Due to the upcoming holiday week we are planning to complete all landscape maintenance by end of the day Wednesday, July 3, 2019. This will help ensure your property is ready for you to enjoy it, undisturbed, over the holiday weekend. In order to accomplish this, you may see the crews working outside of your normally scheduled time. We wish you all a very safe and happy 4th of July.


Our goal is to make sure your property is ready for any holiday festivities, so our crews will be performing regular maintenance services as contracted but on a condensed schedule. Please let us know if you have any special requests or requirements.


The team continues performing mosquito abatement services as we head into the holiday to make sure your outdoor activities are pest free. Please note, we offer organic products, and you can be confident that all of our treatments are safe to use.


Let us know any special requests or extra services you require for events you are hosting in the coming weeks. We will make sure your landscape is looking its summer best. Call your Account Manager directly, or call our office: 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.
