Healthy St Augustine grass lawns look great. They are lush and green, with a nice texture underfoot.
When you walk on them, they don’t crunch or feel like walking on ice. They look great in the summer and they look great in the winter.
Overwatering not just St Augustine grass but any type of grass will kill it.
In fact, overwatering is the number one cause of lawn-care problems, according to the University of Florida IFAS Extension. It can damage a lawn in several ways:
- Too much water at one time will wash away soil nutrients and compact the soil, making it hard for grass roots to grow.
- If water stands on top of the soil for too long, it will drown the grass roots.
The roots need oxygen to live, just like we do. Without oxygen, they die and decompose into the ground, which makes the soil even harder for new grass to grow.
5 Signs You’re Over Watering St Augustine Grass
Here are 5 signs that you are over watering St Augustine grass:
1 – Limp Grass blades
St Augustine grass that is over watered will appear to be a little greenish, and the leaves will become limp. If you notice this, it is time to cut back on watering your lawn.
2 – Inconsistent Growth
The blades of grass will start to grow in different directions, and not straight up like they should. This is a sign that your St Augustine grass is getting too much water, and needs less water.
3 – Discoloration
The edges of the leaves will turn brown or yellow, which means there is not enough oxygen for the plant to thrive properly. This could also mean that you are over watering your St Augustine grass, so it may be time to cut back on watering it if this happens often.
4 – Dying Roots
St Augustine grass that is over watered can cause root rot which means the roots will start to deteriorate or die off because of too much moisture around them. If you see signs of this happening, it may be time to reduce your watering schedule for your lawn if this happens often.
5 – Mold or Fungus Growth
Watering too much can cause fungus in your lawn which can cause brown spots and dead patches in the lawn itself as well as disease problems with other plants nearby that are susceptible to fungus infections from fungus spores found in infected soil or water sources from over watering St Augustine grass too much!
When Your St Augustine Grass Isn’t Getting Enough Water
This is the opposite scenario to overwatering – underwatering. You could be conservative with watering your St Augustine grass lawn, but with some negative effects.
Here are some signs your St Augustine grass needs more water:
It’s turning brown
St Augustine grass is a warm season grass, which means it grows best in the spring and summer months. When it starts to turn brown in the fall, chances are you’re not getting enough water.
If you notice that there is yellowing between the blades of your St Augustine grass, this could be a sign that you need to water more often or increase how much water your lawn is receiving at any given time.
If your St Augustine isn’t getting enough water, its roots won’t be able to absorb nutrients from the soil as easily as they should be and this can cause yellowing between the blades of grass. This will eventually lead to brown patches on your lawn if you don’t act quickly!
Dry & hard ground
The ground around your lawn should be soft after a rain storm or watering session because that means there is plenty of moisture in the soil for your St Augustine grass to absorb and use as it needs to grow lush and green!
If you notice that there are large areas where the ground feels hard after watering or rain, this could mean that you aren’t giving your lawn enough water at one time or over a period of time during each watering session and it may need more water than what you are currently providing it with!
If you notice that there are brown patches of grass where your St Augustine grass is growing next to the sidewalk, this could mean that there is too much shade in that area for your grass to grow or it may be getting too much water from runoff or sprinkler system overspray!
If you notice this happening, try moving your sprinkler system so that it isn’t watering those areas anymore and if possible, move the trees around the area so there is more sunlight on that side of your lawn!
If you have a St Augustine lawn and you experience a drought or heat wave, this can cause your St Augustine to look thin, patchy and even yellow in some spots!
This is because when St Augustine grass doesn’t get enough water during these times, its roots will start to die off and it will eventually stop growing.
When this happens, you will see large patches of yellowing between the blades of grass which can turn into brown patches if left untreated! To prevent this from happening again in the future, make sure you water at least once a week during hot summer months to keep your lawn healthy!
