Lawn Fertilization and Treatment questions, answered by experts

Despite being moderately high-maintenance, St. Augustine grass is popular for several reasons. The biggest properties that make this grass a winner for southeastern lawns include its salt, heat, humidity, and shade tolerance. This grass species is excellent for coastal regions with high humidity, mild winters, and salty skies. It’s also easy to establish in yards.

Yes—hiring a professional lawn care company is worth it if you don’t have much free time to devote to lawn care. Lawn care pros will ensure that your lawn receives the vital nutrients it needs to grow and thrive, and you’re guaranteed to have a healthy, beautiful lawn. Aside from that, it’s a convenient service that frees up your time so you can do the things you love and enjoy. 

The safest method to avoid killing your turf grass is hand pulling Johnsongrass. You can also apply vinegar for a safer herbicide, but it will still burn your lawn if it gets on it.

A typical schedule may involve four to six treatments annually, but needs vary based on lawn conditions, weather, and maintenance goals.

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.
