Is My Lawn Dead?

Tuesday, July 19th, 2011

With every day that passes during this miserable hot and dry spell, Tulsa area lawns continue to turn from green to brown from the effects of the drought.  Some homeowners have given up on even trying to keep up with the watering demands this summer as they watch their lawns turn brown and dormant. Leaving folks to wonder…”Is my lawn dead?” It’s not dead, but it’s sure not very pretty or healthy.

Dead or Dormant?

Not dead, dormant

No the lawn is not dead--only dormant.

Bermuda grass and zoysia grass are warm-season grasses that are well-adapted to hot weather.  However, they still need soil moisture in order to grow and survive. When the weather is as extreme turf will naturally just shut down and go into summer dormancy by turning brown. It’s not dead–it’s just dormant, same as it is during the winter when it’s brown and not growing. As long as the temperatures remain as they are, and no rainfall or irrigation occurs, the turf will remain brown and dormant. This is just the natural response the plant has in order to survive.  (more…)

It’s in the Genes!

This week I attended a conference at Oklahoma State University (go pokes!) on winterkill and spring dead spot. I know it doesn’t sound too exciting for most folks, but that’s what I do—take care of turf. So, I went to see if there was any new information on these two things which have caused me to lose hair every spring over the past 26 years.

Yea, that bermudagrass looks pretty dead, Dr. Martin!

My previous blog was about winterkill. And yes, we sure enough have had some from the winter of 2009/2010. Dr. Dennis Martin, the head of the turfgrass department from O.S.U., showed us the damage they received on their turf plots, spoke about the factors involved in winterkill, along with recommendations on what to do to help bermudagrass turf recover.

It’s always amazed me over the past 26 year when homeowners look at their lawn, and it’s damaged from winterkill, not as green, has a few more weeds, etc, than maybe the lawn across the street. “Why does my lawn look so bad, and Billy Bob across the street doesn’t do anything with his lawn, and look how nice it looks!” We’ve seen some of this with the winterkill event, with some lawns being damaged, even just in certain areas, while other lawns are just fine.

Winterkill of Bermudagrass

Wednesday, April 28th, 2010

Winterkill along a concrete edge, where soil temperatures were colder. Also, too much ice melt could have caused this.

I recently received a memo from Dr. Dennis Martin, Turfgrass Extension/Research Specialist from Oklahoma State University, concerning winter-kill of bermudagrass. Although it looks like the problem is not as severe as he and others believed it would be, there are areas of turf that have been damaged, or are just slow to come out of dormancy. A recent Tulsa World article also had information about winterkill and the effect it was having on local golf courses.

Even during the mildest of winters in Oklahoma, several node and internode segments of the aerial shoot system of bermudagrsss are killed by freezing temperatures. Sunlight  then bleaches the dead tissue to a straw colored appearance. Following these events and while temperatures remain too low for sustained regrowth, people refer to the bermudagrass as “being dormant.”

The relatively severe winter of 2009/2010 has resulted in above average winter-kill of bermudagrass across Oklahoma. “Winter-kill” simply means that part or all of the turfgrass plant died during the winter season. Winter-kill can occur from either acute or extended exposure to low temperatures. It can also be due to complications from the interaction of low temperatures and any number of stressing factors such as insuffient or excessive soil moisture, shade, excessive traffic, soil compaction, low mowing height, insufficient or excessive nutrients, or any number of other predisposing stressful physical, chemical, or biological factors.

The Native American Lawn

Monday, March 15th, 2010

My wife and I recently spent a Sunday afternoon driving up to the Tallgrass Prairie Preserve northwest of Tulsa. The Nature Conservancy purchased 29,000 acres of prairie land several years ago with the goal of recreating a functioning tallgrass prairie ecosystem, preserving the native biodiversity of the prairie. If you’ve never taken the short drive up through Skiatook and on to Pawhuska, it’s worth the trip.


Buffalo, along with fire, are nature's way of "mowing the grass" on the native prairie.


The Tallgrass Prairie Preserve is what this part of Oklahoma, and on up through the great plains, looked like before the area was settled. This is how God created this area—with vast expanses of tall grass, wildflowers, birds, and herds of buffalo. At this time of year, the prairie is a sea of brown, dormant grasses, along with a splattering of buffalo herds roaming the area. And there are no weeds, as urban home lawns that are not treated are showing right now. A weed is a plant growing out of place. In the native prairie, the ”weeds” we are going after in the home lawn, are welcome somewhat, as they do have their place in the native prairie for a time.

This is how your lawn would look if left to itself, after about 200 years of ecological succession.

I’m an ecologist at heart, and by trade. My degree is in Biology, and remember learning about the native prairie, and things such as ecological succession. Many folks think that Bermudagrass is native to Oklahoma, but that’s not true. It was imported from Africa years ago, and has adapted quite well. Zoysiagrass came from China (as a lot of other stuff did also). There are in fact only four true native grasses that grew in eastern Oklahoma for thousands of years, before the Sooners came, and the growth of cities, agriculture, and the urban environment of today.

I love the prairie, and the changes it gives us during the seasons. I love the mountains also, which is obvious, as I’m hiking through the Appalachians from May through September.  The tallgrass prairie is a unique ecosystem, which takes hundreds of years to fully develop, yet can be destroyed in a short period of time. Things we think of as destructive, such as fire, actually bring life to the prairie, through generation of regrowth of green vegetation.

While this isn't the prairie, it works for me.

Face it though–we mainly live in cities. The environment of cities, with turf and landscaping is totally different, which is fine. While I love the tallgrass prairie, I don’t think our neighbors would like buffalo grazing on our lawn. The city I’m sure would not like it if we did a controlled burn on our dormant turf! And yes—I’ve seen some homeowners try that. One actually burned part of his home also. I love green, lush turf in lawns along with healthy trees and shrubs. That’s what works in the urban environment, but it’s not natural! Left to itself, your lawn and landscape would change through the natural process of succession, and eventually end up as a tallgrass prairie, or possibly an upland forrest.

That’s what makes our job as turfgrass managers in fact so challenging. In reality—we’re fighting against mother nature, to produce the ultimate lawn and landscape! Left alone, your lawn wants to have weeds, which is the first stage of succession. And we’re trying to stop that, and produce an environment with just one species—bermudagrass, or zoysiagrass, or fescue.

Now that’s OK. I’m not down on turf—believe me. It’s what works best in the city. It’s my job to produce that nice, thick, green turf. And, there are tremendous environmental benefits in the urban environment to the turf we are growing, even though it’s not native grass to this area. We cannot grow native grasses like Big Bluestem, Little Bluestem, Indiangrass, and Swithgrass in your urban neighborhood. It’s not gonna work. There is a place for them, and it’s on the native prairie. I’m all for that–believe me!

Here's to the "not-truly native" American lawn!

So here’s to the guys like us at LawnAmerica, who are trying their very best to produce great-looking and healthy lawns in Tulsa, Owasso, Jenks, Broken Arrow, Bartlesville, Sapulpa, Sand Srpings, Bixby, and many other communities in Northeast Oklahoma. It’s tough trying to fight the powers of mother nature, trying to produce a tallgrass prairie in your front lawn with the constant introduction of weed species. They are not weeds to mother nature—they’re plants. If our weed-control products don’t get them all, give us a break. We’re trying, but we don’t want to overdo it at the same time.

We’re also proud of our product—healthy, green lawns which add value to your property and benefits to the urban environment. And personally, I always will have a nice lawn to enjoy around my home to play on, walk on, and enjoy. But someday, I also hope to have a tallgrass prairie or an upland forest at the edge of my lawn to walk into and enjoy. As the song goes—give me a home where the buffalo roam.
