As we conclude this month’s discussion of lawn and tree diseases, we want to remind homeowners that they will be the first to notice a problem or symptom in their yard. Look for changes in the coloring and health of your turfgrass each time you mow or trim your lawn. You will spot the changes first. The earlier treatment begins, the sooner your lawn will be restored to its healthy, lush thickness and coloring. This week we are taking a closer at the not-so-magical fungal disease called Fairy Ring. While this disease is steeped in myth and folklore, including the idea that the rings bring luck or fortune, lawn care experts will tell you that this disease is not one to be ignored.
Fairy Rings are a type of fungal disease that look innocently like a ring of mushrooms. In fact, instead of a fanciful fairytale ring built by fairies, these arcs or circles of mushrooms are a sign that there is something wrong under foot. Fairy rings are caused by a diverse family of soil-inhabiting fungi called basidiomycetes. They typically appear as dark green circles in the lawn ranging in size from a few inches to 200 feet or more in diameter. A circle of mushrooms develops around the infected area – thus named the fairy ring! These “rings” can become unsightly and damage the grass roots below the surface. The fungus then depletes the soil of the needed nutrients to grow, and kills the turf.
Controlling this fungal disease can prove to be fairly difficult. Depending upon the size and severity of the rings, lawn specialists can determine if dethatching, aeration, chemical control, or reseeding is necessary. A well-cared-for lawn is the best prevention for this disease. This includes regular watering, dethatching, fertilizing, and soil testing.

As we continue to examine the many types of diseases that can affect the trees and grass around your property, we want to remind our readers that, while they should keep a vigilant eye on their plantings and lawn, diagnosis and treatment is best left to the professionals who can identify the disease correctly and create a treatment plan that is right for your property. This week, we are taking a closer look at the lawn disease known as Dollar spot, including the identification, symptoms, and treatment options available.
This disease is often underestimated because the small round spots only grow to about a few inches around – about the size of a silver dollar! Unfortunately the spots, which lesions in the shape of an hour glass on the width of the blade of grass, can mean that the disease is killing the turf clear down to the root. This, in turn, could cause serious damage to your beloved lawn. Dollar Spot, like the other diseases discussed this month, is also a fungal disease.
This disease specifically thrives when:
- the temperatures get between 70° F to 90° F,
- the soil moisture is low,
- the humidity is high,
- there is low nitrogen fertility,
- there is too much thatch on the lawn, and
- homeowners cut the grass too short.
Since this disease thrives when the soil moisture is low, a good course of treatment is a watering schedule based upon the climate and precipitation in your area. Included in a treatment plan should be an examination of the nitrogen levels and the health of the soil. If the disease has gotten a hold of the roots in patches around your yard, reseeding may be necessary.

Over the past couple of weeks we have been discussing the diseases that can impact your trees and turfgrass that you have so carefully nurtured throughout the growing season. While no lawn is immune to disease, there are some steps homeowners can take to avoid the growth and spread of these damaging diseases. This week, we are examining Brown Patch including the symptoms, causes, and treatments to get your lawn looking healthy and green again.
Brown Patch first appears as circular patches in your lawn that are brownish-yellow in color and range from 6 inches to a few feet in diameter. The small circles can grow and join with other circles to create larger patches of the disease. This aptly named disease is caused by a fungus called Rhizoctonia. It is one of the most destructive of all turf lawn diseases in that it can sneak up on a homeowner and destroy large patches of lawn seemingly overnight if the conditions are right. Brown patch is most likely to occur during extended periods of heat and humidity when night-time temperatures remain above 68° F.
Brown Patch loves all types of grasses and attacks a wide variety of grass types indiscriminately. Lawns that receive large amounts of fast release nitrogen fertilizer are most susceptible. This disease can wreak havoc on tall fescue, Kentucky bluegrass, and perennial ryegrass.
Once your lawn has been tested and evaluated by a professional, there are a variety of treatments. Call Pro-Tech Lawn Care to find out the right treatment option for your lawn this year. Reach out to us at (603) 382-9644 or Toll Free: (800) 313-4733, and visit our website.
Last week, we began our five-part series on Lawn and Tree Diseases with a discussion of Dutch Elm Disease. This week we are shifting our attention to diseases that can impact your lawn. Red Thread is one such lawn disease that can damage the overall look and health of your turfgrass. Let’s take a closer look at the symptoms, types of grasses affected, and what you can do if you spot this disease in your yard.
The telltale sign that your lawn is infected with Red Thread disease is the appearance of dying patches with red or pink fibers interwoven between blades of grass. The most common cause of this particular turfgrass disease is low levels of nitrogen in the soil. Usually this disease emerges in late May or June, but can be present at any point during the growing season. The conditions that favor red thread growth include: low levels of nitrogen, temperatures between 68° F and 75° F, and high levels humidity.
The grasses that are most typically affected include bermudagrass, bluegrasses, fescues, bentgrasses, and perennial ryegrass.
Red thread can survive for years if left untreated. Since it is not possible to control the weather or the fungal pathogen, it is a good idea to stop this disease by treating the soil through fertilization to raise the nitrogen levels. Have a professional test your soil and regularly feed your turf to avoid this disease and keep your lawn looking lush and green.

The United States Department of Agriculture (USDA) Forestry Division, reports that every year millions of trees across America succumb to drought, disease, pests, and wildfires. Forestry ecologists and scientists are increasingly alarmed, and say the essential role of trees – to provide clean water, lock up carbon, and shelter whole ecosystems – is being undermined on a grand scale. Much of this crisis is being driven by climate change and the spread of diseases and pests. In an effort to educate and inform our readers, this month we will be doing a five-part series on Lawn and Tree Disease.
Dutch Elm Disease (DED)
Dutch elm disease has killed millions of elm trees in the U.S. since the early 1930s. Symptoms of this fungal infection include yellowing of leaves and wilting. The branches and stems of elms also develop streaks of discoloration. The fungal infection impacts the the vascular (water conducting) system of the tree. This results in clogging of vascular tissues, preventing water movement to the crown and causing visual symptoms as the tree wilts and dies.
Dutch elm disease is spread by bark beetles. These beetles travel between sick and healthy trees, thus spreading the disease even further. It is crucial to remove infected trees from your landscape and grind them into wood chips. This stops the beatles from spreading. Dutch elm disease treatment options also include preventive fungicide injections that help protect trees for two to three years, planting trees that are Dutch elm disease-resistant, and properly pruning the branches.
These beautiful trees not only clean the air and provide shade, but also add value to your property. So this fall, take a few moments while you are doing yard clean up to look up and examine the branches, stems, bark, and leaves of the trees in your area.
