One of the best online resources for sustainable landscape and lawn care in Illinois is now available in Spanish. Like its sister site Lawn Talk, Hablemos Del Cesdped includes tips and resources for planting and maintenance, including common lawn care mistakes to avoid.
With help from these sites, homeowners and landscape professionals in northern Illinois can cultivate healthy lawns while still conserving water and preventing harmful chemicals from washing into nearby lakes and rivers. Specific natural lawn care tips include testing soil and adjusting nutrient levels as needed at the start of the season, choosing the right grass for the site, and letting lawns go dormant during dry months. The sites also provide information on lawn cultivation equipment and choosing lawn care services.
Phosphorous is a nutrient that has been linked to significant runoff problems and excessive algal growth in water bodies including the Great Lakes. Recently, Scotts Miracle-Gro announced that they will be removing phosphorous from their line of lawn fertilizers to address the issue and help reduce nutrient pollution problems.
From The Columbus Dispatch:
“The Marysville maker of lawn-and-garden products sees the move as a milestone for its industry, which it says is partly responsible for the phosphorus runoff that feeds one of the nation’s most costly and challenging environmental problems — nutrient pollution.
‘As consumers feed their lawns this spring, they should know they can get great results from our products while also protecting and preserving our water resources,’ said Jim Lyski, Scotts’ chief marketing officer, in a written statement.
Harmful algae blooms in coastal areas of the United States are estimated to have a yearly negative economic cost of at least $82 million, mostly because of their effects on public health and commercial fisheries, according to a 2006 report by the National Centers for Coastal Ocean Science.’

While it may not be lawn care season in many parts of the country, it’s never too early to look ahead to next year and the best methods, tools, and information that are available to ensure healthy lawns and healthy ecosystems.
The University of Illinois’ website “Lawn Talk” is a useful and popular site offering an abundance of information to homeowners, property managers, and landscape professionals throughout northern Illinois.
Now updated and redesigned, the website’s new look and content were made possible in part by the Great Lakes Restoration Initiative and Illinois-Indiana Sea Grant’s Lawn to Lake program. Incorporating information and resources from these two entities has made it possible for the site to move beyond traditional, chemical-heavy lawn care advice by recommending natural lawn care resources. Additionally, the relationship between lawn care and water quality is better represented and respected by the up-to-date information on the site, creating a resource that helps protect the environment while ensuring the health and beauty of lawns and landscapes.
This site update also allows University of Illinois Extension to offer even more multimedia content, including instructional videos, interactive activities and features, and more.
Illinois-Indiana Sea Grant’s education team led a workshop for teachers and administrators in the Blue Island, Illinois school district recently, offering lessons, materials, and training on bringing Great Lakes science to their classrooms.
Susan Ask, who works with IISG’s Lawn to Lake program, sent along some details about the workshop and the enthusiastic reception from the teachers:
“We had a fun and energetic workshop with teachers and principals in the Blue Island School District. The workshop focused on water quality and drew on three major initiatives within Sea Grant: Lawn to Lake, the Great Lakes Field Experiences for Watershed Educators (B-WET), and Increasing Citizen Involvement and Great Lakes Literacy (Center for Great Lakes Literacy).
We began with the basic definition and ecology of watersheds, then moved to an exploration of watershed and water quality issues brought on by urbanization, landscaping practices, and waste disposal. Teachers learned basic ecology that they can teach in their classrooms. We identified point- and non-point sources of pollution and talked about available solutions for individuals and communities to adopt.
After a presentation and discussion, we toured the recently installed rain gardens in the courtyard at Blue Island Elementary School so we could see theory put in to practice. The courtyard contains a rich variety of native plants that creates a beautiful garden throughout the year while also managing and controlling rainwater. Runoff from the roofs will be collected in rain barrels all around the building, and can then be used on the landscape as needed.
The watershed model was a big hit. We used a three-dimensional model of a watershed, with rivers and lakes, houses, farms, factories, water treatment facilities and other developments, to see how water and pollutants move through the community. Teachers will be able to borrow this model for use in their classes, helping students understand the connection between people, land use, and water. But we didn’t just look at problems. The model also let us see how natural lawn care, rain gardens, rain barrels, permeable pavement, and other practices can help prevent pollution and reduce runoff.
We showcased many of the program’s Great Lakes curricula – Fresh and Salt, Greatest of the Great Lakes, and Sensible Disposal of Unwanted Medicines. Teachers broke into groups to experience some of these classroom activities and share how they might incorporate them in their lessons. They also learned how the Great Lakes Literacy Principles will be a great way to introduce current Great Lakes issues to their students.
Most of the teachers told us that they haven’t yet integrated Great Lakes information in their educational activities, but that they plan to do so now after learning more about water quality and educational resources at the workshop.
We’re very excited to see these dedicated teachers assist and guide their students to learn more about the Great Lakes, water quality, and practical stewardship of water and land.”
In addition to Susan, the workshop was also led by IISG’s Robin Goettel and Terri Hallesy. If you are interested in educational materials and opportunities for yourself or teachers in your school/district, contact Robin or Terri at the links above or visit us online to learn more.
Runoff from a variety of land uses, including agriculture and industry, has been identified as one of the primary causes of harmful algal blooms (PDF) in the Great Lakes and surrounding waterways. The danger of these algal blooms comes in the form of botulism outbreaks, toxins, and harmful metabolites – all of which can have serious consequences for native plants, fish, and human health.
One potential solution that has been in use in Ohio is the planting of radishes, not only to help manage water and runoff, but also to improve soil quality for agricultural users.
“The radishes planted in northwest Ohio go in about this time of year and are left in the ground to die, explained our host, Allen Dean. Planting doomed radishes, it turns out, is an innovative technique he has used in recent years to improve soil nutrients and reduce runoff from his Williams County farm.
Here’s the basics on how it works: Farmers plant seeds for a plant called an oilseed radish. It doesn’t actually have to be that plant, but it needs to grow a foot or longer into the soil during the fall in a tubular shape, like a carrot or a parsnip. It also needs to grow a fair amount of foliage up on the ground. Radishes are usually more affordable.
It’s important that the plant drill down into the soil so that when it dies, usually during a mid-January freeze, it decays and leaves behind a v-shaped hole for snow and water to penetrate deeper. The decayed radishes Dean showed us looked like organic socks.
Oilseed radishes are particularly good at absorbing nutrients from the surface and sending them down into the soil as the tubular plant drills it way into the ground.”

A two-part article on WKSU’s website delves into recent research attempting to understand the causes of harmful and often very large algal blooms in Lake Erie. The potential negative impacts these blooms can have include depleting nutrients from the waterway, endangering fish and wildlife health, and causing economic concerns by prohibiting or discouraging recreation, tourism, and other industries.
Part one of the article delves into one major contributor identified by the research: agriculture.
“Financial viability is the bottom line for most farmers here along the Maumee River. The Maumee passes through 4.5-million acres of farmland before entering Lake Erie at Toledo. Along the way it picks up a lot of topsoil from farm fields. Attached to that soil are fine particles of phosphorus, one of the nutrients that helps crops grow, but also feeds algae blooms. No-till farming has reduced particulate phosphorus runoff by nearly 40-percent. But researchers from Heidelberg University say their thirty years of water quality data shows that another form of phosphorus – called dissolved phosphorus – has risen dramatically in recent years. And to reduce that nutrient enough to curb Lake Erie algae blooms will take a whole new set of techniques.”
The second article describes another common source of phosphorous and other problem substances – stormwater and sewage.
“The sport fishing industry, beach resorts, amusement parks – all took a hit from the 2011 algae outbreak. Connor says cities …not just farms…have to do more to stay on top of it.
Overflows from sewage systems that collect storm water and waste water are a fairly regular occurrence in Cleveland, Toledo, Detroit and other communities around the lake. And it’s a huge cost to fix it.”
There is a lot of interesting information in both articles, and the occurrence of and concern over these algal blooms isn’t limited to Lake Erie. All of the Great Lakes and other nearby waterways can be susceptible, so the results of studies such as these are important in helping communities prevent the same types of problems in their areas. Our friends at Michigan Sea Grant have produced a brochure for beach managers that outlines more information about algal blooms, and IISG has produced a card for homeowners that explains how to properly care for your lawn without contributing to the phosphorous problem.
Aging pipes and pollution runoff are big concerns in any city, and the cost to repair or replace old systems is very high. Often it means downtime for entire streets and systems, and a very big price tag to boot.
But cities worldwide are adopting green infrastructure elements to help manage numerous factors, from excessive burden on old systems to pollution management and more.
“Gray infrastructure is the system of pipes and ditches that channel storm water. Green infrastructure is the harnessing of the natural processes of trees and other vegetation — so-called ecosystem services — to carry out the functions of the built systems. Green infrastructure often intercepts the water before it can run into streets and become polluted and stores the water for gradual release through percolation or evapotranspiration. Trees also clean dirty water through natural filtering functions.
Advocates say green infrastructure isn’t just about being green — it makes financial sense, as well. Its cost-effectiveness depends on how benefits are assigned and valued, and over how long a time scale, but green has been shown to be cheaper than gray.”
The article (linked above) features much more information about green infrastructure examples, from Seattle to Sweden and many points in between.
Large portions of both Illinois and Indiana continue to experience very low rainfall and drought conditions, and many homeowners are wondering what to do about their lawns. With water in high demand, several communities place watering schedules or restrictions in effect in order to conserve the available water. But what to do about your lawn?
According to Richard Hentschel, a horticulture educator who works with our
Lawn to Lake program, the simple answer is – nothing.
“’If your lawn is brown, it’s not dead,’ says Richard Hentschel, a University of Illinois Extension horticulture educator based in St. Charles (urbanext.illinois.edu/hort). ‘The grass has just hunkered down into survival mode. The plants have stopped growing and given up on their leaves to conserve water and are concentrating all their resources on keeping their roots and crowns alive.’”
Lawns are capable of surviving the conditions, but one area of concern is trees.
“Lawns are easily replaced, but trees are not. Even large trees need help to survive a drought – and if they die, it can take 20 or 30 years to replace that shade. Stress from the 2005 drought killed trees over the next several years. So put trees at the top of the list for watering.
Let the hose trickle for a good long time in several places under the tree’s canopy. Or spiral a soaker hose loosely around a tree trunk. Or buy a soaker bag at the garden center that will slowly ooze water to the roots. Most of a mature tree’s roots are within 6 to 8 inches of the soil surface.”
Richard Hentschel and Rachel Rosenberg (who is also quoted in the article) are both involved in our Lawn to Lakes program, which provides information to retailers, homeowners, and landscapers about natural lawn care alternatives and their benefits.

A lot of people are probably familiar with the streams, lakes, and rivers near where they live. Many people might even be able to point out where their local water treatment plant is. But what a lot of people might not know is that the water we use often comes from a long, long way away.
Watersheds are areas where water comes together and drains to a common place. In addition to the streams and rivers and creeks that we can see, though, watersheds encompass a huge range of pathways for water, and your nearby water supply might be part of a very large system that spans multiple states.
As a result, even in areas where there aren’t necessarily rivers nearby, what goes into our water directly or indirectly can have a big impact. Development and sprawl, even well outside of cities and away from rivers or lakes, can have a significant effect, and that is the focus of a recent article from The Atlantic Cities:
“Of course, obtaining sustainable development in town isn’t enough, in and of itself, to guarantee high quality, fishable and swimmable rivers and streams. Industry plays a part; utilities and waste water treatment plants play a part; sensitive farming, ranching, and/or timbering play a part, all in different proportions depending upon the particular watershed in question.”
The interconnectedness of watersheds is one of the main motivations behind initiatives like
Lawn to Lake and
Unwanted Medicines – keeping the bad stuff out of our water protects people, plants, and animals across a wide region.
