Actually, I'm sorry to recommend tightening the purse strings in such an economy but you might recommend if she attend religious services or some type of social club to ask for someone in her neighborhood at those functions. They are liable to have simply applied too much weed killer in an area and killed the grass. As her friend monitor the service for her and help her make new arrangements if need be. Since I've been on disability I have a budget so tight that every time I need to buy something I think it over, over and over. And furthermore, before I moved into this house (by the way I save money compared to government HUD rent and will own this house in 15 years although most home buyers lucky for me scoffed at this house as it's not a new one and requires minor improvements) I lived in government HUD apartments and the government housing professional caretakers were frankly a negligent disaster. In fact the Somerset Housing Authority lost a 3 million dollar law suit after they had residents pleading to remove a large unstable tree but they ignored the pleas and the tree fell on an innocent pregnant woman and killed her. They actually have the nerve to appeal the decision but I expect they'll loose. In my time there I had to complain repeatedly about the neighbors dropping heavy things all day and night on my ceiling and infesting the apartment building with bed bugs! I also called the police on several occasions. I witnessed professional exterminators come in a spray a squirt or two of insecticide in the apartment knowing that was useless. I told them about trees and plants growing to the apartment gutters where the grounds maintenance was so negligent and a year later no change. I watched the meter readers fabricate false meter readings for both electricity and natural gas. I had to go to their office and challenge the false readings. I had to good to their office and file complaints against the exterminators. I had to go to their office and file complaints against the neighbors. I eliminated the bed bugs and roaches myself by cutting off the central heat and not using the gas stove for 3 months and washing everything multiple times, including the inside of the vents with Pine Sol. The roaches and bed bugs simply avoided the cold and Pine Sol and stayed in the neighbor's apartments that weren't killed by the Pine Sol and lack of food not that they need much. The above are 'services' from college educated professionals in service to the US government so help out your neighbors when you can. A university professional isn't smarter than you. They are simply educated in a niche that you aren't. And look at US government in Congress and the President and Wall Street and tell me you're going to listen to them and accept everything they say automatically? No way! They sound like the banal comments section on YouTube or 1/2 dozen other web sites. And these lawn service give people with no experience and often no real interest in horticulture jobs caring for lawns simply because they applied for work. Lots of times you don't get what you paid for.

Thanks, all, for weighing in. Yup, NHBabs, this does appear sedge-like (or nutsedge-like, which is the only sedge I'm all too familiar with). I'm fairly certain it's not nutsedge as the root structure is different. So, gyr_falcon, will happily forego those lucky stars today! :) Probably not kyllinga -- one article describes these having waxy leaves, and mine are definitely nutsedgy glossy. jekeesl -- I'm always very careful to use a roots-and-all approach when weeding (Mom and Dad taught us well -- we kids spent many, many a weekend pulling weeds in the yard!), as opposed to plucking the tops (which I have indeed read may stimulate growth). Because they're interspersed in the lawn, I can't use an herbicide. And leaving them untouched wasn't an option as it was apparent the St. Aug was struggling to gain territory. I will run this past the County Extension -- thanks again!

Good point about the shade. Can you post a mid day picture taken from, say, across the street, showing how much shade you get? Generally St Augustine will spread about 2 inches per week when the temps are in the 70s if everything is going well. You applied a chemical fertilizer waaaaaay too early even for the Woodlands. I just read Randy Lemmon's website recommendations. At first it sounded fine, but he gets into preventive treatments for disease, which I STRONGLY disagree with. Your soil requires a healthy population of beneficial fungi to be healthy. Treating it for no reason kills off the beneficial fungi and destroys the soil biology. Then looking at the rest of his suggestions it appears he's selling fertilizers just like Trugreen is. He's just not applying it for you. And he's selling far too much. Growing great St Augustine is really easy. Water deeply (1 inch all at one time) but infrequently, mulch mow at the mower's highest setting every 1-2-3 weeks (depending on how fast it's growing, fertilize once in early May (for the Woodlands) and again on Labor Day and Thanksgiving. You do not need to core aerate. As you pointed out it's hard work. You can do a much better job by spraying the lawn with shampoo at a rate of 3 ounces per 1,000 square feet followed by deep watering. Then 3 weeks later you can reapply if you think the soil has not become soft enough. I sprayed mine in 2012 and after a rain like today it's almost too soft to walk on without turning your ankle. If you want to get rid of weeds, wait until April and spot spray the weeds with an atrazine product. Be careful to read the directions 2 times. You should only spray atrazine once a year so make it count. It will kill just about everything except the St Augustine in 3 weeks. The odd thing about spraying it is you have to walk backwards so you don't walk through the stuff you sprayed. Atrazine is not a friendly chemical, hence these warnings. After a decade or so of doing these lawn care forums I'm willing to go out on a limb and proclaim that most people do not water properly. I mentioned deep and infrequent. Deep is 1 inch all at once. Infrequent depends on the temperature. With temps in the 90s you only need to water once a week. Yes, even in the Woodlands. And yes, even in Phoenix. With temps in the 80s deep water once every 2 weeks. With temps in the 70s water once every 3 weeks. With temps below 70 you can water once a month. This is probably the most important part of lawn care. Once you get the water controlled, then the mowing and chemicals (or organics) will work better for you. I have become full organic and have seen some benefits. If you want to continue with full chemical fertilizers, I would suggest at least once a year you apply an organic fertilizer like corn meal or alfalfa pellets (rabbit chow). These materials feed the microbes living in the soil and make everything work better. These are quite often all it takes to make poor soil healthy again.

Ideally you should start a new topic. I believe you did not get a normal amount of rain this winter. Have you been watering? I ask because I see some nut grass in the pictures, and nutgrass prefers really wet roots. Once you start watering deeply and infrequently, the nutgrass should go away/dormant without doing anything else. Raise your mower all the way to the top. The top is around 4 inches, but it it is 6 inches, so much the better. Look up above in this thread to the picture of my back yard with the cat in it. See how the cat is nestled down into the grass. In fact, since this is your back yard, you don't have to mow it at all. St Augustine will grow up to 32 inches tall. It's not a lot of fun to play in, but the point is the grass will do very well even when left alone. In mid April spray the yard with this product from Walmart. Atrazine is the important ingredient. This herbicide will wipe out everything except the St Augustine and bermuda. Spray on a day with little wind, walk backwards when you spray, and walk into the wind so any wind carries the spray away from you. This is a leaf misting spray, not a soil drench. You don't have to spray longer where the weeds are. It takes about 3 weeks before you realize all the weeds are dead and gone. If you are watering deeply and infrequently, both grasses should thrive. Ultimately the St Augustine will march through the bermuda and choke it out, because the tall St Augustine provides too much shade onto the common bermuda. This will take a few years or you can buy new St Augustine sod to speed up the process. You should not ever need to reseed into bermuda. If you have bermuda and it's not doing well, you're doing something wrong and even new seed will struggle. Besides, for you in Covina the best time to put down bermuda seed is in late June and July. If you put seed down now it won't germinate until late June or July when the soil is hot enough. Two more things: First, spray your yard with baby shampoo at a rate of 3 ounces per 1,000 square feet. If your yard is 1,000 square feet, put 3 ounces into the bottle of a hose end sprayer, fill the bottle with water, set the adjuster on any spray flow, and spray it all out evenly until it is gone. You can use any clear shampoo - it doesn't have to be baby shampoo. Whatever Dollar Tree has and you like the fragrance is fine. Second, call these feed stores to see if they have corn meal, soybean meal, or alfalfa pellets (ask for rabbit chow). Get prices for a 50 pound bag. Any one of these materials will do, so pick any one you like and spread it at a rate of 15 to 20 pounds per 1,000 square feet. Corn meal will be the cheapest at under $10. If they quote you $20 or $30, they're talking about corn gluten meal, not ordinary cornmeal. CGM works, too, but it costs more. All these are organic fertilizers. I think I mentioned to wait until late May to fertilize. If you use an organic, you can do it NOW (two weeks ago). Your soil looks gray and not healthy. If you want to get a soil test, send it to Logan Labs in Ohio. I know UCR and UCD do soil testing in California, but Logan Labs performs more tests on the soil for less money than the universities do. Get the $25 test. Let us know and we'll tell you where to send the results for a free reading telling you all about the soil. As a side note, it looks like someone has topdressed your yard too many times with too much soil. The soil level looks about 1.5 inches too high. It should be down closer to the edge of the concrete. If you ever chose to renovate, you should be removing soil and not bringing in more.
