Have you seen powdery mildew in your St Augustine Grass? This is actually a pretty common issue during warm, wet or humid weather. All of which we are no strangers to. Generally speaking it’s hard to prevent but it’s also pretty harmless to the grass as well. You typically can brush your hand or foot across it and it will fall right off the grass blade. So long as the grass doesn’t appear to be in distress like the ones shown, there no need to react or do anything. It will usually go away the next time you cut the grass of when the weather dries up. In the event it does seem to be spreading or causing a decline to the grass, you will need to apply a fungicide to the affect area. If you’ve got any questions please let us know! Have a great Monday!
