What Is Necrotic Ring Spot?
Necrotic ring spot is a very severe, extremely destructive turf disease caused by the proliferation of a fungus that kills the roots and the leaves of your grass.
Like any fungus, the species that causes necrotic ring spot disease thrives in moist environments, making its appearance if the soil underneath the lawn is not able to drain properly, either because it has become too compacted or because it cannot evaporate excess moisture for some other reason, such as overwatering, improper grass height or prolonged and excessive raining.
Fortunately, necrotic ring spot can be easily prevented with the help of adequate lawn care practices – here is what you should do:
– aerate the lawn first, preferably in fall – remove any plugs of soil and break up compact layers to allow the lawn to breathe;
– apply special fungicides and slow-release fertilizers is how to make grass green and to strengthen the lawn and to protected against fungus;
– use an appropriate lawn watering technique – water the lawn early in the morning, before the lawn is heated up by strong sunshine, to allow the grass to dry properly and to make the most of the water. Don’t overwater the lawn – watering two times a week should be enough;
– Don’t cut the grass too short;
– use clean and very sharp blades to avoid injuring the leaves of grass and to prevent re-infestation with the fungus.
