Lawn Fertilization and Treatment questions, answered by experts

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.

St. Augustine is a hardy grass that’s relatively easy to grow, but it requires regular lawn maintenance to stay healthy. It’s best to keep up with a regular fertilization schedule during the growing season, plus a yearly dethatching to help it properly absorb air and moisture. Watering is also important, so be sure to water it enough to keep the soil moist.

There are several best practices you can do to keep your lawn looking healthy. Knowing when to water grass is among the most important. Having your sprinkler timer set to early morning is best because it gives your grass and plants enough time to absorb water before the sun and wind can evaporate it. To maximize a sprinkler’s impact, aerate your lawn once or twice per year. Doing this achieves better absorption and stronger root systems for your grass.

The best time to apply fertilizer to your lawn is in early fall, though some climates necessitate a different schedule. In most cases, avoid fertilizing late into fall, as this opens up your yard to winter injuries and poor health (though this is a great time to kill weeds.) You should avoid early spring fertilization, as this helps the grass leaves grow, but at the expense of developing root systems. Remember to water your lawn after fertilizing to increase its effectiveness and reduce the likelihood of runoff during a rainstorm. 

A few common lawn maintenance mistakes include failure to use fertilizer, not committing to a yearly maintenance plan, and under- and over-watering your lawn. Other issues that might arise include poor timing of lawn treatments. It’s important to dethatch, aerate, and reseed your yard at the right time of year—preferably in early spring.
