Your lush lawn is your personal getaway and a beautiful representation of your home. However, lawn diseases can hijack your personal paradise and decrease your curb appeal. Here are some of the major lawn problems that can hurt your turf as well as ways you can help prevent lawn diseases.   

<p>Lawn Diseases</p>

Red Thread Lawn Disease:

(aka Pink Patch) is a grass fungus disease marked by small, bleached, light pink or red patches on the lawn. Small, water-soaked spots cover a large portion of the grass leaf, and as they enlarge, the tissue dries out and fades to a tan color.  A balanced lawn fertilization program and specific watering habits can help prevent the occurrence of red thread, however the best first step to disease prevention is a TruGreen® Healthy Lawn Analysis® to identify the specific needs of your lawn.


Thatch isn’t an infestation or infection, but a tightly interwoven layer of plant materials that can develop between green turf and the soil. It holds water but dries quickly, like a sponge, and it has basically no nutritional value for your grass. Lawn aeration is most effective as a preventive measure, ventilating the soil before thatch builds up.

Brown Patch:

Brown patch strikes all the common turfgrasses. The fungus causes spots on leaf blades that can eventually turn whole leaves brown, and creates large circular patches of blighted turf. Hot, humid conditions make it worse. Proper watering in midday to prevent wet grass at night as well as proper mowing on a frequent basis to promote air movement and drying of the leaf blades can help prevent this lawn disease. Brown patch activity and damage can be accelerated by unbalanced or over-fertilization; a Healthy Lawn Analysis can help determine if your lawn has the right amount of fertilization.

Summer Patch:

At its worst during drought and heat stress, summer patch loves to attack Kentucky bluegrasses (as well as some ryes and fescues). It’s one of the more difficult lawn diseases to control. Yards that are under stress from heavy foot or pet traffic will tend to have a higher occurrence of the disease. Avoiding unnecessary stress to the turf and reducing foot and pet traffic can help lessen the symptoms. Relying on a lawn expert to provide recommendations is the best option for effective prevention.

Dollar Spot:

Dollar spot is named by its characteristic of small tan patches, about the size of a silver dollar, that form in the early stages of the disease and grow outward. Most common when humidity is high but rainfall has been low, this fungus is at its worst when leaves are wet but the soil is dry.  Implementing the right watering and mowing schedule can help to control this lawn disease. Also, since dollar spot often occurs on thatched, drought-stressed lawns, a lawn aeration service can help control thatch and improve moisture penetration. 


Difficult-to-control weeds can cause lasting damage to lawn health. Most of the toughest weeds are perennials that can regrow even after intensive treatments. Maintaining vigorous turf that can out-compete weeds is the best method for control. A TruGreen lawn expert can recommend a customized plan designed specifically for your grasses and soils.
