Get a Watering Permit for New Sod

Many states are suffering from water shortages. This means that cities have to be careful with how much water they use, especially if it is being used to water your yard.

There have been restrictions on irrigation across the country. They limit when and how long we can water. These restrictions apply to any location that uses city water, your well water, hand watering or an automatic irrigation system.

What can you do? Well, if your contractor didn’t apply for a water permit when he got your sod permit, you’ll need to apply for one. These permits usually cost less than $10 and can be granted within one day. These permits allow you to drink water every day for 30 consecutive days, and then every other day for 30 consecutive days.

Factors that could impact how often/how heavily you need to water your St. Augustine Sod

Every lawn is different. There are many factors which will impact how much water and how frequently you water your St. Augustine grass. Let’s take a look.

Different soil types

It is important to consider the type of soil when deciding how often to water new St. Augustine soil. Different soils have different drainage patterns. For example, the sandy soil in Galveston, Texas drains faster than the red clay in Birmingham Alabama. Because of this, when applying my watering schedule for new St. Augustine sod, you need to be careful that you don’t over or underwater.

Angle of the Yard

Extra caution is required if your yard slopes or your sod is at the bank. To ensure water can flow down the slope, I recommend watering from the top of the hill. You’ll find that if you start at the bottom of the hill and work your way to the top, you will more than likely end up overwatering the bottom of the hill.


Weather can have two effects on your watering. The rain is the first. If you water during rainy seasons, you must compensate for the rain. Avoid overwatering during rainy seasons. It is important to stay on top of the weather forecast.

The second factor is heat. When you water in summer heat, the heat can cause a lot more evaporation. This means you need to keep an eye on the soil. You should also check how much water is absorbed by the soil and how quickly it dries out.

Signs that your new St. Augustine Sod is either too wet or too dry

You should be alert for potential problems with your new sod while watering it, or looking through the window. These are signs that you may be overwatering your plant or submerging it.

Check out the New St. Augustine Sod

Things can get complicated, just like other jobs in the yard. Sod is no exception. At first, I know you’ll probably check your new St. Augustine sod every five minutes, which is a good thing.  Instead of waiting for signs of over- or underwatering, here’s a few things you can do.

Roots Knitting

It might take a few days for the sod to start to root itself in the soil. Give the edge of the sod a gentle lift and see if it’s knitting into the soil below. If it is, it’s a sign that things are moving in a positive way.

Edges drying out

As I mentioned, be aware of the sod’s edges drying out. You don’t need to wait until they have dried out and started to cause a problem. You can catch it early by looking out for signs of drying and browning. By keeping an eye on the matter, you can prevent future problems.

Check the soil moisture

You can check the soil’s moisture in several ways. To pull the dirt back, you can use a shovel and a small garden trowel. You could also use your hands. You can purchase a garden moisture monitor for as little as $20 at Lowes and Home Depot.

Adjust your watering program

My final recommendation is that you make any adjustments to the watering schedule that are necessary. You can give the lawn more water if it appears dry. If it’s looking soggy, then ease up a little.
