St. Augustine is a popular type of warm-season grass, especially around the gulf coast. The beautiful blue-green color, its resilience to salt, and its tolerance heat set it apart from other types of grass. However, it’s helpful to keep in mind the pitfalls of planting St. Augustine grass in Hammond, LA.
The southern chinch bug will occasionally dine on zoysia grass, bermuda grass, and other warm-season grasses, but it prefers St. Augustine. Damage from chinch bugs will appear as irregularly shaped sections of dying or dead grass. Watch your lawn for these brown patches with a ring of yellowing grass around them. These shapes will expand and eventually devour your entire yard.
Proper maintenance is key to keeping chinch bugs out of your lawn. Eliminate and prevent thatch buildup, since this is where the pest prefers to nest. Mow your lawn once a week, only cutting off about ⅓ of the grass blade. Aerating and proper irrigation will also help boost your lawn’s health and keep the chinch bugs at bay.
St. Augustine is susceptible to many types of lawn fungus, including Brown patch, Fairy rings, and Dollar spot.
Brown patch is the most common problem among St. Augustine lawns. This fungus appears as brown circular patches of dead or dying grass. It usually shows up in the spring or winter, as the temperatures cool off and excess water sits on the lawn.
The best way to treat brown patch is to prevent it. Begin by watering your lawn in the morning, giving the excess water time to evaporate. Don’t water too frequently (a depth of 4 to 6 inches should be plenty.) Avoid nitrogen-rich fertilizers and make sure to aerate your lawn.
St. Augustine grass spreads quickly throughout your lawn, filling in patchy areas and keeping your yard looking lush and healthy. However, this quick-spreading grass doesn’t know when to quit. It may be challenging to keep the St. Augustine out of your flower beds.
Using a thick mulch in your flower bed will block the wandering grass from getting any sunlight, effectively killing it. A glyphosate-based herbicide is also extremely effective against St. Augustine grass, and it won’t harm your ornamentals. Just make sure to follow the instructions on the label and avoid contact with your skin and eyes.
