Get the low down on lawn disease and find out if Sunday’s chelated iron product can help.

Lawn Disease

Managing lawn disease can sound overwhelming. While there are some lawn diseases that are very difficult to diagnose (e.g. root diseases), leaf diseases are more readily identified and solvable with the right treatment. 


Common foliar diseases in turfgrass:

  1. Anthracnose
  2. Brown and yellow patch
  3. Dollar spot
  4. Snow mold 
  5. Red thread
  6. Rust

Lawn Fungus Control

Lawn disease appears when a fungus (or fungi) is present, environmental conditions weaken your lawn, and grass is susceptible and likely already stressed from other issues (soil compaction, heat, weeds, pests, other fungi). Adjusting your normal lawn care habits is key to getting fungal issues under control. There are three main aspects of care that you’ll need to consider or fix immediately. 


Adjust watering practices. First things, first. Your lawn’s watering schedule should be adjusted and fixed immediately when a foliar leaf disease is detected. At a minimum, this will halt the spread of the issue and allow you to reset watering to a cadence suited for your region, current weather, and specific lawn characteristics (drainage, grass type, etc.). 

Wait for the right conditions. Fungal issues shouldn’t be removed or repaired during poor climatic conditions like high temperatures and heat stress. This will likely only exacerbate the problem. We recommend waiting for the fall when conditions are more favorable for repairing the lawn.

Know all existing turf issues. Other existing turf problems will make disease problems worse, especially other foliar diseases. Take on IPM for lawn disease: make a checklist of current lawn issues and appropriately identify the fungal disease in your lawn so you can properly address the problem.

How-to Mend Lawn Disease

Do everything you can to dry it out

  1. Fix your watering practices and stop relying on the same watering routine throughout different seasons
  2. Begin seasonal auditing of systems, ensuring you are auditing between seasonal shifts and weather patterns
  3. Water on a set schedule, and allow some drying time between watering sessions


Sunday ProTip: Allowing your lawn to dry and recover between waterings is the most valuable thing you can do to mend fungal issues.


Seeding for repair 

  1. Prep the lawn for seed by mowing, removing clippings, and raking away debris that might hinder seed from reaching the soil
  2. Depending on grass type(s), seed-in or propagate better varieties of grass
  3. Water appropriately to ensure germination and root establishment
