St. Augustine grass is a popular warm-season grass in the south that makes a great turf grass for your lawns. It’s loved for its coarse blades and fast growth rate which helps prevent weeds from taking over. As beautiful as this grass is, it is still susceptible to brown patches that can appear in early spring and late fall. These unsightly patches can ruin the appearance of your lawn and allow for weeds to invade. Thankfully, there are some methods and precautions you can take to prevent brown patch from taking hold of your grass.
Proper irrigation is important in keeping brown patch at bay. Watering your lawn too late will keep your grass damp at night which is the right conditions for brown patch to appear. Instead, it is recommended to water in the early morning to allow enough time for any excess water to dry out before night.
Obviously you need to water your grass, but how much is too much. Remember, brown patch thrives under damp conditions. Since St. Augustine grass is a warm-season grass it doesn’t need to be watered too often. Only water when the grass is dry or beginning to show signs of drought. Every 5-10 days is ideal.
Fertilizing is an important part of lawn
maintenance but knowing which time to do so is just as important. The nitrogen found in fertilizer promotes lush new growth which is an easy target for the brown patch fungus. This usually occurs in the early spring and late fall when conditions are more suitable for the fungus to grow. To avoid helping out the fungus only fertilize with nitrogen-based fertilizers in late spring or summer
Compacted soil and thatch buildup can prevent water, air, and nutrients from getting to the roots of your grass. When this happens, water will pool or runoff, creating ideal conditions for brown patch to grow. To prevent this you should aerate your lawn at least once a year.
It’s important to mow St. Augustine grass regularly to avoid the spread of the fungus. Over time grass clippings settle under the grass and create thatch. As we stated above, thatch is a contributor to soil compaction as it prevents water and air from getting to the roots. Thatch can also retain moisture which is a breeding ground for brown patch.
