You can use a fungicide to help control powdery mildew, but you should apply it judiciously as it can damage soil health and persist in the soil. Most of the time, proper watering, surface drying, and limiting shade can control powdery mildew without needing harsher interventions. If you have a repeated problem with powdery mildew, you can also try planting a shade-resistant type of grass that will be less susceptible to the fungus.

Whether you’re putting down fresh seed or reseeding, there are a few things to keep in mind when seeding your lawn. Be sure to choose the correct seed for your climate, seed at the right time of year, and water two to three times a day for the first week. Generally, Dudley recommends seeding in spring and fall as it is usually cooler and rainier.

A quick search online may recommend that you give your dog apple cider vinegar to help decrease the pH level of your dog’s urine. This method won’t help your yard, though. Most turf grasses thrive on slightly acidic soil, so apple cider vinegar won’t make much of a difference. 

The main cause of grass death by dog urine isn’t the pH level anyway—it’s usually the excessive amount of nitrogen that kills your grass.

It depends on the type of grass and the condition of your lawn. We advised you to fertilize your lawn at least twice per year. However, warm-season grasses and nutrient-deficient lawns may need to be fertilized up to four times a year. Remember, you don't want to over fertilize either, so soil testing can help to determine if your lawn lacks nutrients and if it’s ready for another application.
