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.

A spot herbicide for weed control is effective at killing crabgrass and not grass, but it depends on the type of herbicide. Always check the label to ensure that your herbicide is safe for grass but tough on crabgrass. Overall, spot treatment is ideal because it puts fewer herbicides into the soil, which can damage the soil. If you’re wanting a natural remedy to crabgrass that also won’t harm surrounding grass, you can also hand-remove crabgrass or even pour boiling water or 5% vinegar over crabgrass as a spot treatment.

If your lawn has a higher pH than recommended for your type of grass or it looks yellow, sulfur can help. If your lawn is slow to grow and not very lush, it could also benefit from a  higher sulfur content. Sandy soil is especially vulnerable to sulfur deficiencies.

Most businesses schedule services weekly or biweekly to maintain a professional appearance and healthy lawn.

If you plan on laying new grass seed, try to wait eight weeks before stepping on it. You might need to wait an entire season to drive your car across the driveway. Sod establishes itself in the ground in about two weeks.
