I cannot answer what you have in your yard. If your home is fairly new construction chance are very likely it is a hybrid called 419 aka Tifway-I. But also understand the casino's have some of the best horticulturist money can buy. Ever been in Belagio Conservatory, Wynn, or Mirage and notice the beautiful gardens? If I am not mistaken I believe Bellagio has a huge nursery that grows most of the flowers plants, and tress for most of the Casino's in Vegas. Anyway I have never inquired what variety of Bermuda they have, but what I can tell you it is a semi-dwarf variety. If I had to guess I would say TifGreen or Sun Turf. With all that said, at this time of year you might be seeing Rye grass. They overseed with a Rye mix in mid October so it is green in Winter. The about late March, early april they will spray with a herbicide to kill off the Rye quickly as the Bermuda greens up. What I do know is the grass is not growing in soil. Like a high end golf green it is a soil less medium and in this case a very coarse sand. Anyway the grass is maintained everyday by some of the best pros in the biz.

So I take it that if the fescue is dead, then its dead. I can't revive it without re-seeding, correct? Bah. Yep when it is dead it is done and has to be reseeded. Bermuda on the other hand goes dormant when it does not receive enough water, and comes back with water. However it will not wait forever and will also eventually die. Question about bermuda - the bermuda I've seen around Las Vegas needs to be trimmed very short. Its almost like a carpet. I have doubts as to whether my mower can actually mow that short. Yes Bermuda is kept very short. That is why I mentioned it has to be mowed at least twice a week if irrigated and fed. However not all Bermuda grass is alike as their are many varieties all requiring different maintenance techniques. 1. Most of the common types from seed are used for pasture hay and erosion control and those are not mowed but rather cut once or twice a year to harvest hay. They are rarely ever fertilized except once in the spring and never irrigated. Not something you would want for a turf grass 2. Improved common seeded types for turf grass and the quality varies quite a bit in leaf size and cutting height. Some like Princess (aka P77) are near golf coarse quality requiring to be kept very short of 1 inch or less, fertilizing every 30 days during growing season, regular irrigation to maintain color. The there are several varieties which are medium quality than can be maintained around 1 to 2 inches which is probable the best fit for you. They still require frequent fertilizing and irrigation to maintain color, but you can have a decent looking stand using a push mower set for 1-1/2 inches. 3. Then there are the hybrids varieties. These are from sod, plug, or sprigs only. No seed available for hybrids. These are the high quality varities and they fall into two classes semi-dwarf, and dwarf. I will not go into dwarf varieties because they are stickily professional care used for golf greens and very wealthy people who have full time pros maintaining it. What you likely see around town and on all golf coarse fairways and tee boxes is a semi-dwarf hybrid variety. The two most common varieties used and widely grown by sod farms is Tifway-I (aka 419), and TifSport. In most states where Bermuda grass is grown Tifway-I is the default choice of all builders and landscapers. TifSport is gaining popularity as it is a little finer grain, denser, and better cold tolerance than Tifway-I. Either way they are both fairly high input grasses and best maintained at 1-inch or less with a reel type mower. However many and I would say most maintain them with a rotary mower between 1 and 2 inches. However those that do use a rotary mower do so because that came with there home and they just do not know better. It works, but not optimal. As to watering I split a different way than David recommends. Normally I would agree once a week with a deep soaking is the best method as a rule of thumb. But not for out here. Unless you are blessed and top soil was shipped in to your yard, or in a flood plain where soil is carried in from flooding, you do not have soil. You have rubble and coarse granite/quarts sand eroded from the surrounding mountains of LV. There is nothing in it to hold water and coupled with bone dry 10% or less humidity and searing temps you have to water much more frequently than most folks do. In summer once a day is the normal practice out here. At least in Prescott and Phoenix it is. Maybe Vegas is different, but I doubt it as the soil and climate are very much alike except Vegas is a little cooler than Phoenix. You guys only get up to 110, where Phoenix 115 is long sleeve shirt weather in summer. Now with that said I can say you are watering too frequently at 3 times a day for a few minutes each time. To be honest I do not know exactly what to recommend, other than when you do water, do so very early in the morning, and only once in a day. I imagine during cooler months once about every 3 or 4 days. During the blistering summer days it will take watering every day in the mornings. A lot is going to depend on which grass type you choose and actual soil conditions. I suggest you go around to a few nurseries and landscape companies to seek advice, maybe even visit a golf course and talk to a supt. You should be able to get a pretty good idea if you do that. Or if you have a neighbor with an impressive yard, stop by and ask them as most people will be flattered and tell you exactly what they do unless they pay someone to do it for them. I know from visiting Vegas often and now living in AZ, yards are rare even in the upper class neighborhoods. Just takes too much WATER to maintain them. That is why I mention Buffalo grass to be considered.

If that's the case, you need to date more often.

dRahme - My sister just wants a low maintenance and drought tolerant garden. She doesn't like gardening at all. Since I plan on putting a small lawn and gas BBQ near the guest house, I'll likely put the shrubs and trees on the perimter. I'll definitely check out your site to get some ideas, though. In her neighborhood, most people have the usual rock garden with a few drought resistant shrubs and daisies. I can't imagine her running outside to water when the temps start to get over 100 degrees (when it needs it the most!). And I understand that if plants are in the ground, the automatic sprinklers can only run for a few minutes on Satuday. In containers, though, there is no restriction on length of watering. Thanks for your thoughts Bill
