Living in Florida, you know how quickly your St Augustine lawn can go from lush and green to parched and brown. This is especially true during the dry winter months.
In Florida, the best time to plant new St Augustine grass is in the spring or fall, when temperatures are mild and rainfall is more frequent. This allows the grass to establish a strong root system before the hot summer months.
St Augustine grass requires about 1 inch of water per week, either from rainfall or irrigation, to stay healthy. It's also a good idea to water your lawn deeply but infrequently to encourage deep root growth.
During the hot summer months, it's essential to maintain your lawn's height at 2.5-3 inches to prevent scorching. Regular mowing also helps to promote a dense, weed-free lawn.

Florida Lawn Care Seasons
Florida has a subtropical climate, which means our lawn care seasons are a bit different from those in cooler regions. Spring arrives relatively early in Florida, and this is the perfect time to start watering your St. Augustine grass two to three times a week.
During the summer months, your St. Augustine grass will be fully mature, and you'll need to water it two to four times a week, depending on your soil's moisture-holding capacity. Sandy soil, for example, will require more frequent watering.
In the fall, you can reduce your watering schedule to one to two times a week, depending on the rainfall in your area. This is also a good time to add an autumn-blend fertilizer to your lawn. Here's a quick rundown of the recommended watering schedules for each season:
In the winter, your St. Augustine grass will enter a dormant stage, and you should reduce your watering and mowing schedule to once a month. However, if your area doesn't get cool enough for the grass to remain dormant for more than a few days, you should apply a low-nitrogen fertilizer in the winter.

Remember to only water your lawn when necessary, and avoid overwatering, which can lead to root rot and other problems. By following these tips, you'll be able to enjoy a lush and vibrant lawn all summer long.
Watering
Watering is a crucial aspect of Florida lawn care, particularly when it comes to St. Augustine grass. This type of grass requires consistent watering to thrive.
In Florida, St. Augustine grass needs about 1 inch of water per week, which can come from rainfall or a sprinkler. Using a sprinkler in the morning is recommended to avoid burning the grass in the full sun.
Overwatering is a common mistake that can lead to pooling water and fungus. It's essential to avoid overwatering to keep your lawn healthy.
St. Augustine grass prefers deep, infrequent watering, typically once or twice a week. This practice helps strike the right moisture balance and prevents stress or damage from drought or excess moisture.
Early morning watering is recommended to reduce evaporation. Aim to provide about 1 to 1.5 inches of water per week, factoring in any rainfall.
Here's a rough guide to help you determine how often to water your St. Augustine grass based on your soil type:
Keep in mind that these are general guidelines, and you should adjust your watering schedule based on your specific climate and soil conditions.
Lawn Maintenance Tips
St. Augustine grass is a low-maintenance option for Florida lawns, but it still requires regular care to thrive. Start by watering your grass two to three times a week in the spring, and adjust the frequency based on soil type and weather conditions.
In the summer, St. Augustine grass needs more frequent watering, typically two to four times a week. Water in the morning or early afternoon to avoid evening humidity that can lead to lawn fungus.
Mowing is another crucial aspect of St. Augustine lawn care. Keep the grass blades 3-4 inches long, and mow every 5 days to 2 weeks, depending on the time of year and weather. In cooler climates, wait until the grass greens up in the spring to mow.
You should also apply a St. Augustine-safe weed and feed fertilizer about two to three weeks before the grass turns green in the spring. This will help control weeds and provide essential nutrients for healthy growth.

By following these lawn maintenance tips, you'll be well on your way to growing a lush, healthy St. Augustine lawn in Florida.
Lawn Care Practices
Lawn care practices for St. Augustine grass in Florida are crucial for maintaining a lush and vibrant lawn. Fertilizing is a key aspect of lawn care, and it's best to fertilize in late spring and early fall, avoiding the cooler winter months and rainy season.
To promote strong root development and a dense, lush turf, maintain a mowing height between 2.5 and 4 inches, and mow every 7 to 14 days during the growing season.
Proper mowing and fertilizing practices can help prevent weeds, disease, and pests in St. Augustine grass. Here are some tips to keep your lawn healthy and vibrant:
By following these lawn care practices, you can enjoy a beautiful and thriving St. Augustine lawn in Florida.
Grass Care
Fertilizing your lawn is crucial for keeping it lush and vibrant, especially for St. Augustine grass. Proper fertilization involves applying a balanced turf fertilizer with elements like nitrogen and potassium during the spring green-up.
To fertilize effectively, conduct a soil test to determine its specific needs. Depending on the soil test and soil pH, more or less fertilizer may be needed. So, apply three to four times throughout the growing season so the grass receives the right nutrients at optimal times.
Mowing St. Augustine grass correctly is vital for its health and aesthetic appeal. This grass type thrives when cut to a specific height and frequency. Maintain a mowing height between 2.5 and 4 inches to promote strong root development and a dense, lush turf.
It's better to mow grass when it is dry to avoid clippings clogging the mower. You should also follow these mowing tips: Keep grass blades 3-4 inches long, mow every 5 days to 2 weeks, and mow when the grass is at least 75% green and the soil temperature is above 65 degrees.
Dethatching is necessary to remove a layer of dead grass and other organic matter that settles just above the surface of soil. This can be done early in the spring, before applying your pre-emergent herbicide, by mowing your lawn to half of its normal height and then using a dethatching rake or mechanical de-thatcher.

Here are some general guidelines for maintaining your St. Augustine grass:
- Water two to three times a week in the spring and fall, and two to four times a week in the summer.
- Apply a St. Augustine-safe weed and feed fertilizer two to three weeks before you expect the grass to turn green.
- Avoid using herbicides on your grass if the temperature gets above ninety degrees.
- Pull any weeds by hand and mow as necessary, but at least once a week.
- Add an autumn-blend fertilizer and a St. Augustine-safe herbicide in the fall to get rid of any weeds.
- Reduce mowing and watering to one to two times a month during the winter if your area gets cool enough for the grass to remain dormant for long stretches.
The ideal pH range for your soil should be 5 - 8.5. If your soil is too acidic, lawn lime can be added to raise the pH level of your soil.
Sodding
St. Augustine grass is grown through a unique process where plugs of already grown grass are planted instead of seed, due to the high cost of seed.
This method works well because the stolons or runners on the plugs will quickly grow and fill in bare patches of grass to form a thick carpet of turf.
Watering the new sod is crucial to help the roots take hold in the lawn, which is essential for a healthy and lush appearance.
In tropical and sub-tropical climates, St. Augustine plugs can be planted year-round, as the grass doesn't go dormant.
Common Lawn Issues
St. Augustine lawns in Florida are prone to lawn issues, and it's essential to be aware of the common problems that can affect your turf. Gray spot, root rot, and large patch (also known as brown patch) are common fungal diseases found in St. Augustine lawns.
These diseases can thrive in the warm, tropical climates of Florida, making it crucial to take preventative measures to protect your lawn. Fungicides are an effective way to keep fungi at bay, and can also help treat existing fungal diseases.
Chinch bugs, grubs, and mole crickets are also common pests that can damage your St. Augustine lawn. Chinch bugs suck the moisture out of grass blades, while grubs infest the root system, weakening the grass.
Weed Control
Weed control can be a challenge, especially in South Florida lawns. Overwatering is one of the biggest mistakes people make, but it's not the only issue. Hand-picking weeds is an option, but it's arduous and not always effective.
Chemical herbicides can be used, but make sure to follow the label instructions carefully. Schiavon recommends using a product that's specifically designed for lawn care, as using a combination of weed killer and grass fertilizer can be a recipe for disaster.
Pre-emergent herbicides can be applied in early spring to prevent weed seeds from germinating. Post-emergent herbicides are effective for dealing with existing weeds, but be sure to check the label for temperature restrictions.
Manual removal of weeds is often enough for smaller infestations of less than 100 square feet. This can be a good option for dealing with weeds like crabgrass.
Here's a quick rundown of the best times to apply pre and post-emergent herbicides:
By following these tips, you can keep your lawn looking its best and prevent weeds from taking over.
Treating Chinch Bugs in My Lawn
Chinch bugs are a frequent pest in St. Augustine grass, causing yellow and brown patches that can begin in areas that are over-watered.
To identify chinch bugs, look for tiny black-and-white colored adults on leaf blades. This is according to UF.
There are multiple granular and liquid chemical treatments for chinch bugs available in stores. Heavy infestations can take multiple applications of insecticides to eradicate the problem.

Some effective insecticides for chinch bugs include trichlorfon, bifenthrin, and carbaryl. These chemicals can be found in products available at stores like Sodsolutions.com.
For extreme infestations, trichlorfon is recommended. However, always follow the instructions on the product label and take necessary safety precautions when using insecticides.
Here are some common signs of chinch bug infestation:
- Yellow and brown patches on the lawn
- Tiny black-and-white colored adults on leaf blades
- Areas of the lawn that appear to be affected by drought
By being aware of these signs and taking action early, you can prevent chinch bugs from causing significant damage to your lawn.
