Augustine Grass Die?

how to revive st augustine grass
You may be wondering why your St. Augustine Grass is dying and how you can revive it. There’re a few potential causes – not enough water, poor soil quality, pest infestations or diseases like brown patch root rot fungus or gray leaf spot. Excessive fertilizer applications can also cause burning and wilting of grass.

With proper care and attention, however, you should have no trouble reviving your lawn to its former glory!

Lack of Water

Lack of water can cause your St. Augustine grass to wilt and die, as was John’s case. He had fertilized it regularly, but his lawn still needed help. To revive it, water deeply (at least 6 inches) twice or thrice a week with clean filtered water. Make sure to adhere to a regular watering schedule.

Fertilize at the recommended frequency and avoid over-mowing and scalping. Perform aeration techniques like dethatching and soil tests.

Proper lawn prep before planting is essential too. Ensure adequate soil depth and add organic content into the mix for added nutrition!

Poor Soil Quality

If your lawn’s soil quality is sub-par, the roots of your St. Augustine grass won’t be able to grow deep and strong enough to keep it healthy. To improve the health, a few strategies should be employed, including:

  • Pre-emergent herbicide application before planting new grass, to prevent weeds.
  • Adding compost or humus to enrich soil with organic content.
  • Applying balanced fertilizer for nitrogen and iron requirements.
  • Aeration techniques like dethatching regularly.
  • Taking soil tests for pH levels and nutrients deficiencies/excesses to identify amendments needed.
  • Mulching to conserve moisture, suppress weeds, reduce erosion and improve overall condition of grassy areas.

With these tricks under your belt combined with proper watering schedules, you’ll have an attractive lawn in no time!


You’ll want to keep an eye out for pests like grubs and chinch bugs – they can cause damage if left unchecked. Organic control methods are best – introducing beneficial insects or using natural solutions instead of chemical treatments. Plant resilience is important too – remove leaf litter regularly from the grass surface and mulch around plants for extra protection. If you’re facing a fungal issue due to overwatering or high humidity, there are fungicidal treatments available. Plus, proper care techniques like deep watering twice weekly (at least 6 inches into soil depth) and mowing at no more than 2-4 inches in height.


You should be aware of common diseases that can affect your lawn, such as brown patch, root rot fungus and gray leaf spot – all of which can cause wilting and browning. Fungal infestations are a major issue for St. Augustine grass due to its propensity to hold excess moisture in the soil.

To prevent these issues from arising, proper fertilization strategies should be implemented along with over seeding practices or irrigation techniques designed specifically for this type of grass species to ensure adequate drainage.

Cultural practices, such as regular dethatching, will help reduce dead spots caused by excessive organic matter build up and reduce fungal disease risk.

Brown discoloration may indicate an underlying problem related to gray leaf spot or other types of fungi, so it’s important to address potential fungal problems and provide preventive measures.

Excessive Fertilizer Applications

Avoid over-fertilizing your lawn, as too much can burn the grass and cause irreversible damage. Visualize the consequences of excessive fertilizers like a wildfire spreading across an arid landscape, consuming everything in its path and leaving barren destruction behind.

The timing for fertilizer applications is critical; it’s best to wait until St. Augustine Grass has resumed growth after high heat or drought before applying any fertilizer at all. Soil testing should be done regularly to determine missing or excess nutrients in order to avoid damaging effects from improper fertilizing methods on St Augustine grass roots and root rot fungus diseases which are common in poorly drained soil with poor air circulation caused by compacted soils due to excessive use of fertilizer products containing nitrogen levels that exceeds recommended levels for this type of turfgrass species.

Natural alternatives such as composting can help reduce weed control while improving soil quality rather than using chemical remedies which may not always provide desired results when dealing with certain types of weeds commonly found growing within areas where st augustine grass is installed.

For optimal lawn health care, ensure proper mowing heights (2 – 4 inches), adequate watering techniques (1 – 1/12 inch/week), deep water twice per week throughout summer months, and regular dethatching every spring season will also aid greatly towards healthy looking st augustine lawns free from disease outbreaks due to extreme heat conditions along with avoiding over-application of fertilizer at all times during warm seasons.

Reviving St. Augustine grass can be achieved with the right steps and care. Water your lawn adequately to allow for deep penetration and encourage strong roots. Improve soil quality to prevent shallow root growth and grass death due to lack of nutrients or fertilizer burn. Dethatch the lawn to remove organic matter buildup, preventing air from reaching the root zone. Replant bare spots with plugs or runners to restore bald patches caused by disease or pests, and increase overall thickness and greening of the turfgrass area. Bringing life back into your landscape!

Step 1: Water Your Lawn Adequately

Regularly providing your lawn with the right amount of water, as well as deep-watering twice a week during hot months, is essential for maintaining lush and healthy grass.

To revive St Augustine Grass you need an adequate fertilizing program along with regular mowing at the correct height (2 ½ – 4 inches). You also need to control pests such as chinch bugs or grubs that can weaken even a healthy lawn by damaging its roots system.

Watering your St. Augustine Grass shouldn’t be done lightly; it needs to soak down to at least 6 inches in order to keep root rot fungus away and provide enough moisture for proper growth.

Soil testing can help identify missing or excess nutrients so they can be corrected accordingly, which will ultimately give strength back into this type of grass when revived properly.

Step 2: Improve Soil Quality

To maintain a healthy and strong lawn, you need to improve the soil quality. One way to do this is by mulching with bark chips or straw. This will help retain moisture and stop weeds from getting access to sunlight, preventing dead patches in your St. Augustine grass.

Aerating the soil regularly can help break up compacted areas, letting water and nutrients reach deeper roots for better absorption.

Fertilizing requirements vary, depending on local knowledge of what type of fertilizer works best. Use it no more than three times a year for optimal results. Keep an eye out for proper pH balance throughout the season, and use weeding techniques when needed.

All these elements together will create a thicker appearance in your grass over time.

Step 3: Dethatch the Lawn

Detaching your lawn with a dethatching rake will help break up any compacted areas, allowing the roots to get access to more water and nutrients. It’ll also reduce the amount of thatch build-up, which restricts grass growth. Aerating soil better for fertilizing and facilitating proper over seeding strategies while managing weeds in different varieties of turfgrass effectively are just a few benefits.

Dethatching is especially beneficial for St Augustine Grass as its high tolerance makes it susceptible to root rot fungus diseases when there’s too much thatch buildup around the base of plants. So, dethatching regularly ensures your St Augustine Grass fares well all year round.

Step 4: Replant the Lawn

Now it’s time to start replanting your lawn and get the lush, green grass you desire. You can do this by using St Augustine Grass plugs or runners for bare spots in the lawn.

To ensure a successful re-growth process, make sure proper fertilizer timing is followed and mulching techniques are applied correctly. Different types of grass varieties may require different mowing heights, so research which type of St Augustine Grass seed works best for your area and climate conditions.

With proper care, you’ll soon see rich blue-green blades popping up everywhere! Applying a pre-emergent herbicide before planting will help prevent weeds from appearing later on, as well as protect against root rot fungus disease caused by overwatering or extreme humidity levels.

When mowing with your lawnmower, make sure it’s set at an appropriate height. Cutting more than one third of blade length should be avoided, if possible – too low won’t allow enough nutrients into the roots, potentially leading to death.

Water Your Lawn on a Regular Basis

Water your St. Augustine grass lawn on a regular basis to keep it green and healthy. Think of it as a deep, nurturing drink that will give it life!

Aerate your lawn – essential for oxygen exchange and water absorption. This helps revive the roots.

Perform soil tests regularly to determine fertilization schedules and irrigation systems. Bring back a lush, thick carpet of turfgrass.

Control weeds. They compete with St Augustine Grass for nutrients and water, leading to an unhealthy lawn if left unchecked.

Apply fertilizer according to label instructions. This ensures the right amount of nutrients are delivered at appropriate times, promoting root growth and overall healthiness while reviving St Augustine grass.

Dethatch Regularly

Regularly dethatching your lawn can help make sure it’s healthy and vigorous. Dethatching is the process of removing a decomposing layer of organic matter that accumulates over time on top of soil, reducing its ability to absorb moisture or fertilizer. This helps promote strong root systems, reducing the risk of turf diseases like root rot fungus disease, and prevents weeds from taking hold in your grass.

Fertilizer application should be done with caution. Applying too much at once can burn your lawn. Customer service representatives can advise you on how best to apply it, depending on what type grass you have planted, for optimal growth results without damaging it further.

Mowing Should Be Done With Care

When mowing your grass, take care not to cut too much of the blade at once. This can damage and even kill it. Use a low setting when cutting St. Augustine grass to avoid scalping or removing more than one-third of the blade length in each pass. Otherwise, it will suffer from stunted growth and may die.

To ensure optimal health for your lawn, consider using fertilizer safely. Follow package instructions and don’t over-fertilize or let fertilizer burn occur. Overseed techniques can help thicken patches which have died out due to lack of nutrients. Aeration methods break down compaction and increase water absorption rates, plus allow oxygen to move deeper into root zones.

Pruning should be done yearly with quality tools designed specifically for St. Augustine Grass, like edging shears. Soil testing should be done in springtime before applying fertilizers. This will help professionals determine the type and amount of nutrient content needed.

Utilize proper watering techniques: 1-1.5 inches per week with deeper soakings reaching 6 inch depths. Regular applications from certified Lawn Experts will help keep St. Augustine Grass lush and green all year round.

Use Pre-emergent Herbicide

To keep your lawn looking lush and green, consider applying pre-emergent herbicides. They help control weed growth and protect the lawn from diseases like root rot fungus.

Professional lawn care companies like TruGreen can provide assistance with fertilizing tips, overseeding tips, aeration techniques, weed control methods and disease prevention. This helps keep your St Augustine grass healthy.

Applying pre-emergent herbicide also improves the nutrient uptake capability of the soil, which is essential for good quality grass growth over time.
