Which turf grass is best


There are over 5,000,000 acres of turf grass grown along the Gulf Coast. All are warm-season turf grass, each with its own characteristics and its own pros and cons. Others, like buffalo grass – although considered a warm-season grass – do not do well in Gulf Coast lawns. There are, however, three types of grass which grow reasonably well here. (Lawn statistics for the Gulf Coast)

Bermuda grass

If you’re new to the area, and want to see what Bermuda grass looks like, go to the nearest sports field. Sports fields usually have one of two types of surfaces. One is artificial turf. The other is Bermuda grass. The chief advantage of this turf grass is it has few disease or insect problems and, although it is a warm-season grass, it is more cold tolerant than other warm- season grasses. However, the main requirement for Bermuda grass is that it needs full sun. It is also much more tolerant of traffic than other types.

One disadvantage is that it does not tolerate shade, it turns brown after the first frost. However, just because it turns brown after the first frost, it is still alive but dormant. It will return to green in the early spring. Many gardeners (including myself) despise Bermuda grass because it is aggressive, quickly invades garden beds and is a devil to remove.

Bermuda grass needs about one inch of water a week during the growing season (April-October). That includes rainwater. So, if it rains an inch this week, you don’t have to water it at all – good news on your water bill. In fact, the three warm-season grasses mentioned here go dormant in the winter. Here is an example of a lawn that has not been artificially watered in over 2 years.

St. Augustine grass

St. Augustine is the most commonly used turf grass along the Gulf Coast.It is relatively shade-tolerant and may remain green but dormant throughout most winters here. Like Bermuda grass, it does need a lot of water (about one inch a week). It is the most tolerant of salt water, which can be a boon during hurricane season.

This turf grass is susceptible to disease and insect damage, its two major disadvantages.

Zoysia

Zoysia grass is becoming more and more popular among residents along the Gulf Coast. It’s almost as shade-tolerant as St. Augustine and has few disease or insect problems, Zoysia also requires much less water than either St. Augustine or Bermuda grass and it tends to be more wear-resistant than either of the two other grasses.

A disadvantage is that it is the earliest turf to turn brown at the first frost. It is also the last to green up in the spring.

When to sod

Although theoretically, all three grasses can be sodded anytime, the very best times to sod are late October and early April. Those months are cooler than our hotter late spring and summer and allow the grass roots more time to grow without the stress of extremes of temperature. April is also the best time to aerate your lawn and add compost to it.

Questions residents have about lawn care


Q. I have trees in my yard, and the grass doesn’t want to grow well under them. What can I do?                                                                                                                                   A. Remember that grass is a plant too, and requires sunlight to convert energy to food. Of all the turf grasses that are adaptable to southeast Texas and south Louisiana, St. Augustine grows best in shaded areas. However, if it can’t get any sunlight at all, it will cease to grow under your trees. If your grass is getting thin in under-tree areas, you might think of hiring an arborist to do some minor pruning on your trees to allow more sunlight in.

QIs now the right time to use a “weed and feed” product?                                                  A. NO time is the right time to use weed and feed products. The proper time to apply the pre-emergence herbicide used in this product is before the weeds begin to grow…late February to early March. The proper time to fertilize or “feed” turf is mid-April. Applying them both at the same time is a waste of time and money. Applying “weed and feed” too early, and the fertilizer is dissipated or leached out of the soil by the time the grass needs it. Applying it too late, and the “weed” part has no purpose, because the weeds have already emerged and seeded.

Q.Why is the soil under my lawn rock hard?                                                                              A.Too much water, too many salt-based fertilizers and pesticides, too little organic matter in the soil are primary causes of hard soil. It has become compacted, making it harder for grass roots to penetrate. Pull up a handful of grass, roots and all. If the roots are shorter than three inches, your soil is too hard for the roots. Good St. Augustine, for instance, can grow roots as deep as at least six feet.

Q.What can I do to fix this?                                                                                                          A. Aerate your yard. Then add a half-inch of organic material (compost) across the top of your lawn. The compost will enter the soil and the aeration will help water and air to penetrate it (roots need air and water too).

Q. When is the best time to sod my lawn?                                                                      A.Springtime (April and May) or early fall (October) are the best times to lay sod. So, now’s a good time to resod. Remember to add organic material when you do resod.

Q. How often should I water my lawn in late spring and summer?                                        A. St. Augustine needs only one inch of water weekly, and even less if it rains. However, that doesn’t mean you NEED to water twice a week. For 2017, experts and empirical data have indicated that, because of rain and high humidity, we needed to irrigate lawns only 12 weeks out of the entire year. And about half of that time, we didn’t need to irrigate more than one time during the week. The best way to gauge how much to irrigate is to have a rain sensor installed (they’re very inexpensive – about $20.) or install a Smart controller.
