Watering during the afternoon and early evening. Watering at this time can cause fungus issues because in high humid areas you want to cut down on the time your grass spends wet/humid in heat. At night the water sits longer on the grass and is not absorbed faster. So mix this with high humidity it encourages fungus and/or disease.
Infrequent mowing-Maintaining a lawn at the recommended mowing height will improve its ability to resist diseases and give it a greater aesthetic appeal. The frequency with which the lawn is mowed should be based on the growth rate of the grass. Lawns should be mowed often enough so that no more than one-third the length of the grass blade is removed at any time. Removing too much of the grass blade can increase the susceptibility to several diseases such as leaf spot fungus by depleting food reserves in the plant, making it difficult for the plant to recover from stress and injury.
Dull mower blades- Maintain sharp mower blades to avoid mechanical damage to turf. Dull mower blades rip the grass blade instead of cutting it clean which opens up the grass blades to diseases like fungus.
How to reduce the risk of Leaf Spot Fungus?
Proper watering and mowing practices.
Keeping your lawn at a good height and making sure that you are aerating and seeding yearly
Proper Turf Density- Making sure your lawn gets proper seeding every year if it needs it and that its thick, lush and healthy
Establish a good fertilization and weed control program.
However even still with all the proper watering, mowing and lawn care practices you may still get a fungus and need to get a fungus fungicide treatment. If this happens just give us a call and we will take care of the rest.
