How Tall Does St. Augustine Grass Grow? When Should You Mow It?

When it comes to lawns, there are a few different types of grass that people tend to choose from. One popular option in Florida is St. Augustine grass. This type of grass can be found in many yards across the country.

But one question that often comes up is: how tall does St. Augustine grass grow? In this blog post, we will answer that question and provide some additional information about this type of grass.

How Tall Does St. Augustine Grass Grow?

If you don’t keep it trimmed, St. Augustine grass will get to be 12 inches tall and fill with flowers and seeds. If you want to maintain a neat lawn, however, you should mow it down to between 2-4 inches.

How Often Should You Mow St. Augustine Grass?

St. Augustine grass should be mowed once a week during the growing season, which is typically from April through October in Florida.

In general, St. Augustine mowing heights during the summer are about 2–4 inches. Never remove more than a third of the leaf blade at a time when mowing in the summer. If you remove more than that, the grass will become stressed, and it may be discolored for a short time.

Taller blades provide more shade for your root system to remain cool and hydrated during the hot summer days.

During the winter months, you can reduce the frequency of mowing to every two weeks or so. Just be sure not to let the grass get too long, as this can lead to problems come springtime.
