St. Augustine grass can be one of the more difficult grasses to care for, especially when it comes to dealing with dead spots. The good news is there are steps you can take to restore and revitalize your lawn.
First, determine the cause of the dead spots in your lawn. Soil compaction, drought, over-fertilization, thatch buildup, and improper mowing are all possible causes of St. Augustine dead spots. Once the source of the issue has been identified, the best course of action for treating the spots can be taken.
For soil compaction, aerating the lawn will help to break up the compacted soil, allowing water and nutrients to reach the grass roots more easily. Additionally, watering the grass deeply but infrequently can also help reduce soil compaction.
An easy solution to drought-related dead spots is to water the entire lawn regularly and consistently, as this will help to evenly distribute moisture without wasting too much water.
When it comes to over-fertilization, the damage can sometimes be too severe to fix, so it’s important to identify the issue early and reduce the amount of fertilizer applied. In cases of minor over-fertilization, the excess can be absorbed by the grass and the spot may recover on its own.
If thatch buildup is causing the dead spots, dethatching will be necessary to help break up the layer of debris and allow the grass to more easily access sunlight, water, and nutrients.
Finally, in cases of improper mowing, identify any areas that may have been mowed too low and reseed the spots with St. Augustine grass seed.
Overall, fixing St. Augustine dead spots can be a challenging process, but with the right steps and regular maintenance, you can have a healthy, vibrant lawn in no time.
Why do I have dead spots in my St. Augustine grass?
Dead spots in St. Augustine grass can be caused by a number of factors, including inadequate irrigation, pets, and even grubs. Without sufficient water, the grass will typically start to turn brown in areas and can die off, leaving dead spots.
Pet urine can act as a fertilizer, but when the nitrogen found in it builds up it will start to burn the grass and also leave dead spots. Lastly, grubs are a common issue when it comes to dead spots – they will usually feed on the grass roots and can damage the lawn.
In order to prevent dead spots in your St. Augustine, make sure to keep your grass adequately watered and fertilized, maintain it frequently, and address any grub issues promptly. Doing these things will help encourage lush, healthy grass that won’t be susceptible to dead spots.
Will dead St. Augustine grass come back?
Unfortunately, once St. Augustine grass is dead it is not likely to come back. It is a very sensitive grass and can die from a variety of environmental factors such as excessive heat and drought stress, soil compaction, overfertilization, poor drainage, herbicide damage, and more.
To ensure that St. Augustine grass is able to come back and remain healthy, it is important to regularly provide adequate nutrition and water, mow at the right height, reduce soil compaction, monitor your soil’s pH levels, and protect it from pests or harsh elements like excessive heat or cold.
You should also avoid using a herbicide unless absolutely necessary, and never apply too much fertilization. If the original problem that caused the death of the grass has been resolved and the grass is planted in a healthy environment, then the dead grass may be able to come back to life over time.
How do I treat dead spots in my lawn?
Dead spots in your lawn can be treated in a few different ways. The first thing you should do is identify what is causing the dead spots. Common causes include fungus, grubs, too much or too little water, inadequate light, or fertilizer burn.
Once you have identified the cause, you can address it properly. For example, if the cause is fungus, you can try treating the spots with a lawn fungicide. If the cause is grubs, you can use a grub control insecticide to eliminate the problem.
Inadequate light can often be improved with additional sunlight or aerating of the lawn. If the spots are due to either too little or too much water, you should adjust your watering schedule accordingly.
Lastly, if the cause is fertilizer burn, you should reduce your fertilizer application or adjust the type of fertilizer you are using.
Finally, once you have eliminated the cause, you can sow grass seed in the dead spots in order to help the area recover. Make sure to use freshly purchased grass seed and to keep the area well-watered for optimal growth.
Additionally, consider using a starter fertilizer to help promote the growth of the grass. Once the grass is growing, you can continue your regular mowing, watering, and fertilizing of the area to ensure it remains healthy and free of dead spots.
What fertilizer should I use for St. Augustine grass?
When fertilizing St. Augustine grass, it is important to choose the right fertilizer to ensure optimal health and growth. The best fertilizer to use for St. Augustine grass is a slow-release, balanced fertilizer with an equal ratio of NPK, or nitrogen, phosphorus and potassium.
Nitrogen promotes green, healthy growth and should make up about half of the total nutrients in the fertilizer. Phosphorus encourages strong root systems, and potassium strengthens the overall health of the grass.
It is important to check the labels of the fertilizer to make sure that the NPK ratio is equal, typically appearing as a “4-4-4” or “3-3-3”. If applied correctly, a slow-release fertilizer should provide mid to late season nutrition throughout the growing season.
Additionally, St. Augustine grass should only be fertilized twice a year – once in late spring/early summer and then again in the fall – using 1 to 1.5 pounds of fertilizer per 1000 square feet each time.
Applying too much fertilizer at one time can damage the grass, so it is important to follow the instructions on the package.
Will St. Augustine grass fill in bare spots?
Yes, St. Augustine grass can be used to fill in bare spots. As a warm-season turfgrass, St. Augustine grass grows to be a dense, lush lawn when given the right conditions. To fill in bare spots with St.
Augustine grass, it is important to use appropriate planting techniques and lawn care practices. To begin, remove any dead, dying, or diseased grass before patching the bare spots. Then, till the bare area to a depth of two to three inches using a rake, garden fork, or soil aerator.
Break up any large clumps of soil and add a 1/2 to 1 inch layer of topsoil. Make sure that the area has good drainage. If the soil is overly saturated, add some sand to help improve water drainage. Once the soil is ready, spread the St.
Augustine grass seed or sod over the area, and gently rake the area to create a subtle gradient. Finally, water the area deeply, and keep it well-watered until the grass is firmly established in the ground.
Adequate lawn maintenance is essential to maintain a healthy, uniform lawn; mow, edge, and fertilize on a regular basis.
Will St Augustine recover from brown patch?
Yes, St. Augustine will recover from Brown Patch. This lawn disease is caused by a fungus called Rhizoctonia solani, which thrives in humid temperatures between 80-90 degrees Fahrenheit. It is usually seen in areas of low nitrogen and high thatch.
Brown patch begins as light green irregular patches and progresses to dark green and tan dead patches. To help prevent further outbreaks of Brown Patch, you should provide regular fertilization with a high nitrogen content, reduce thatch buildup and mow your lawn with a sharp blade to reduce disease pressure.
Additionally, water the grass deeply to promote a deep root system that can better resist disease and stress. With proper care and maintenance, St. Augustine can make a full recovery from Brown Patch.
How do you bring dead grass back to life?
Bringing dead grass back to life can be done by following several steps. First, reduce the amount of traffic on the grass to allow it time to rest and recover. If the grass was previously over-watered, make sure to water less often and more deeply to help the grass develop deeper roots.
Next, aerate the soil to improve air and water absorption. Use a soil test to determine which lawn fertilizer would be best for your grass type and apply it evenly. Finally, keep your grass mowed at the recommended height for the type of grass you have.
Mowing at the recommended height will help promote healthier grass and keep it from becoming overgrown and weak. Following these steps can help bring dead grass back to life and keep it healthy in the long term.
How do you get rid of GREY leaf spots?

What causes grey leaf spot?
Grey leaf spot is a fungal disease that is caused by the fungus Pyricularia grisea, which is found in tropical and subtropical climates around the world. On turfgrass, it typically causes lesions or spots on the leaf blades, which may become circular and turn tan or grey in color.
Symptoms of grey leaf spot can include light to dark green spots on the grass, fading of the color, weakened turf, and early death of the grass. Grey leaf spot tends to be most active during warm, humid weather and is usually more severe on weeds than on turf.
Other cultural care practices that can help reduce grey leaf spot include mowing height, proper fertilization, and proper irrigation. In addition, fungicides may be necessary to reduce and control infection.
What does fungus look like in St Augustine?
The appearance of fungus in St Augustine will depend on the variety present. And therefore it can come in a variety of shapes, colors and sizes. Generally, St Augustine fungus will appear as circular spots with a light grey-brownish hue and a white center.
These spots can range in size from half an inch to multiple inches in diameter. They often have a powdery texture, which is made up of the spores that have been released from the fungus. Fungus can also form long brownish-black threads in the grass, known as string-like structures or hyphae.
Additionally, some fungus can cause discoloration in the leaves and produce white or tan puffballs, which are also referred to as mushrooms.
Why does my grass look silver?
Grass that appears silver in color is usually a sign of a fungal disease that is known as powdery mildew. This fungal disease is caused by a variety of fungi and can occur in any type of grass, although it tends to be more common with cool-season turfgrass species.
Powdery mildew is caused by a lack of air circulation and can be initiated by humidity and shading from trees. Grass that has powdery mildew will appear silver in color due to the white fungal spores that are visible on the leaf blades.
To reduce the likelihood of powdery mildew in turfgrass, it is important to maintain proper turf cultural practices—such as proper mowing and fertilization, adequate irrigation, and aeration. Additionally, improving air circulation around the grass by pruning trees and shrubs can also help to prevent the disease from occurring.
If powdery mildew does appear, chemical fungicides can be used to control its spread.
How do I know if my lawn has fungus?
Some of the most common symptoms include discolored or wilting grass, bald spots or patches, and mushroom-like growths on the grass or ground. Discolored grass may appear yellow, brown or even in other colors.
Wilting grass appears drooping or flattened down. Bald spots or patches may appear as bare or empty areas of grass. The mushroom-like growths can come in a variety of colors, such as white, tan, yellow, brown, or even dark purple and black.
If you notice any of these signs in your lawn, it’s important to identify and treat the fungus as quickly as possible to avoid it spreading and harming the rest of your lawn. If you’re unsure if your lawn has fungus, it’s best to consult a professional lawn care expert.
How do you treat lawn fungus?
Treating lawn fungus can be a tricky and lengthy process, but taking a few simple steps will help you get rid of this pesky problem. The first step is to determine the type of fungus you’re dealing with in order to choose the most effective treatment method.
