That’s why we created our lawn program, so we can get your grass healthy again with minimal headaches.

Diseases We Treat

Large Patch Disease - Large patch typically occurs November through March when temperatures fall below 80 degrees Fahrenheit. This disease occurs when there is excessive rainfall, excessive irrigation or extended periods of high humidity when the turf is wet for 48 hours or more.



Arrow lawn disease program treats gray leaf spot disease in Florida

Gray leaf spot disease - Most common in late spring to early fall where there are prolonged periods of rainfall or excessive application of quick release nitrogen sources, gray leaf is identified when the disease causes yellow spots on the leaf. As it matures, these spots turn into elongated brown and gray spots, which can kill the plant over time.

Pythium root rot - Root Rot can appear anytime pf the year when wet soil conditions are present as a result of excessive rainfall or irrigation. Poor drainage will compound the problem. These patches of disease look orange or yellow and gather in distinct patches. They typically look like wet patches in the yard and feel slimy when touched.

Identifying Lawn Fungus

  • Brown patches of dead grass that continues to grow
  • White or yellowing patches of grass
  • Spotting on leaf blades
  • Stunted grass growth in patches
  • Darkened, wet, or slimy-looking grass areas

How to Prevent Lawn Fungi

  • Mowing practices - Scalped lawns are more susceptible to lawn diseases, so mow your grass to the correct height and keep mower blades sharp. We recommend a mowing height of 3-4” for St. Augustine turf, the most common type of turf in our area.
  • Aerate soil - Once or twice a year, it is important to aerate your lawn to allow water and nutrients to better reach grass roots.
  • Water - Properly water your lawn in the early morning twice a week in spring and summer and once a week in the fall and winter.
  • Grass type - Choose your grass based on what is suited best for the Florida climate so they are able to better protect against lawn diseases in your area.
