Common Causes of Dead St. Augustine Grass

Common Causes of Dead St. Augustine Grass
Are you having trouble reviving your St. Augustine grass? You’re probably dealing with one of three common causes: pest infestation, grass diseases, or over-fertilization. To achieve the best results in restoring your lawn to its former glory, it’s important to correctly identify and address each of these issues.

Pest Infestation

Pests can be a major problem for your lawn, so keep an eye out and take preventative measures to ensure that your turf stays healthy. Chinch bugs and other insect larvae are common culprits of St. Augustine grass death.

Grub control is also necessary since grubs feed on the roots of the grass plant, causing it to die off.

Using a grub killer product or applying copious amounts of fertilizer may help with fighting pests, but should only be done after soil testing has been conducted in order to maintain balance within the soil environment.

The deep watering technique, along with regular mulch fertilizing, will help grow strong roots. Meanwhile, using lawn repair products high in mulch and fertilizer will revive dead patches caused by insect damage.

Regularly monitoring your lawn for pest infestation is key. Taking early action when needed can save you from having to replace large sections of St.

Grass Diseases

Watch out for signs of disease in your lawn, as it can quickly take a toll on the health of your turf. To prevent diseases like brown patch or gray leaf spot, maintain soil quality with organic content and fertilizers.

Regularly water according to a schedule and apply fertilizer correctly based on soil testing results.

Disease control also relies on pest management. Remove thatch buildup, which creates an ideal environment for pests to thrive in. Taking proactive steps, such as adding layer compost or hummus, will help improve grass growth and reduce the presence of disease-causing organisms in your lawn’s ecosystem.

Maintaining healthy soils through proper application techniques is essential when it comes to preventing common diseases from ruining St.


Overfertilizing can quickly damage your turf, so be sure to apply fertilizer correctly based on soil testing results. Lawn experts recommend a balanced approach when it comes to fertilizers – too much or too little will create an imbalance in the soil and lead to grass death.

Furthermore, using herbicides as part of patchwork repair may do more harm than good if not used properly. To avoid excessive chemicals damaging St Augustine Grass, use manual weed removers instead of chemical-based solutions and always conduct a comprehensive soil test before applying any product containing nitrogen or phosphorus content.

With these tips from lawn professionals in mind, you’ll be able to maintain healthy soils with proper application techniques that prevent common diseases from ruining your beautiful turf!

Using a Grub Killer

Using a grub killer to protect your St. Augustine grass can be like constructing an impenetrable fortress around it. Applying chemical treatments and monitoring the soil quality will help fend off pesky pests.

Emphasizing proper watering techniques and practicing regular lawn maintenance, such as mowing at the correct height, are key for the optimum health of your turf.

Repairing With Patchwork

Repairing your turf with patchwork is a great way to get it looking lush and healthy again! Adding fertilizers, mulch layers, and herbicides can help revive a small patch of your lawn.

Keep a consistent schedule for watering and maintain suitable conditions year-round.

Dethatch Regularly

Dethatch Regularly
Regularly dethatch your turf to prevent insect damage and keep it looking lush. Dethatching is the process of removing excess thatch, which is a layer of dead and decaying organic matter lying between the grass blades and soil surface.

Removing this layer helps avoid disease and allows for better water penetration into the ground.

If you’re replanting in spring or early summer, wait until late fall before dethatching so your St.

To ensure deep watering throughout this time period, use a hose with an adjustable nozzle set on low pressure. Stick a pencil or screwdriver into the soil to check adequacy at least once per week.

Finally, apply herbicide prior to planting new grass plugs. Thoroughly remove sod from affected areas and then apply garden-safe weed killer products high in mulch and fertilizer, such as Lawn Repair product specifically designed for St.

Mowing With Care

Mowing With Care
Maintain a mowing height of 2.5 to 4 inches for your St. Augustine grass, so it can thrive in the warmer weather and withstand heavy foot traffic. Additionally, regular mowing helps prevent disease by removing excess thatch and allowing better water penetration into the ground.

When it comes to lawn care maintenance for this species of grass specifically, here are some key tips:

  • Water Management: Stick a pencil or screwdriver into the soil weekly to check adequacy before considering deeper watering techniques like reverse osmosis or filtered water systems, which help apply moisture more evenly over larger areas.
  • Fertilizer Types: Use natural fertilizers with low nitrogen content as they allow less leaching from rainy periods while providing essential nutrients during spring months when temperatures start rising again!
  • Soil Testing & Weed Controls: Conduct soil testing prior to planting new grass plugs to determine if additional organic material is needed.
  • Mowing With Care: Keep an eye on blade length setting at all times – never lower than 2 ½ inches because doing so will cause damage due to both heat stress and insect infestations affecting root establishment.

By following these simple steps, you’ll be able to successfully revive your St. Augustine Grass easily and quickly while avoiding common issues such as those commonly seen with other types of turfgrass varieties out there today!

Watering adequacy should also not be overlooked. Stick a pencil or screwdriver into the soil weekly to check if more water is necessary prior to the spring months when temperatures begin rising again in Central Texas regions!

Fertilization strategies are equally important here too. Using natural fertilizers with low nitrogen content will prevent excess leaching while providing essential nutrients that are required for proper growth recovery during those hot summer days ahead!
