What weed killer are you using? Follow the directions and don't spray the trees. Spray when there is no wind and the temperature is not too hot (directions will specify when it's too hot and it could volatize). Makes sure the weed killer can be used with the type of grass you have (read the directions).

Wide spectrum Weed and Feed type products aren't a great idea under trees. Some are sensitive. Some are not.

I'd spot spray the weeds with the correct amount of the proper herbicide, but I'm not familiar with dollarweed as we don't get it up here and we don't have Bermuda. Somebody more familiar with Bermuda and dollarweed will chime in, I'm sure.

I dont think your live oaks will be killed. Just buy the right product for the grass. Look for "Safe for Bermuda, St Augustine" on the lablels. You can use a hand pump sprayer around the trees. It does not take much. Just a light mist, you don't have to soak the plant area or you will kill the grass too. . Be patient and give it 2 weeks and you can probably just spot spray what survived (you missed). I don't have any experience with dollar weed, but clover is pretty easy prey.

Also buy a concentrate bottle where you pour a little in a garden spray bottle or a pump sprayer to apply. Don't buy those bottles already ready to attach to your hose that the big box store all push. You get almost nothing for your money. Concentrate bottle is usually same price and you get 3X more for your money.

Like this. One application of the ready made Vs about 3 applications of the concentrate. Same price.

I would avoid the "weed and feed" stuff. If you need to attack weeds, use a herbacide. If you need to fertilize, use a fertilizer. I would avoid the "one bag does it all" stuff. They seem to cater to the lazy and misinformed and my understanding on what I have read is they dont excel at either of them. What if the "weed & feed" herbicide did not work well on your weeds? You going to apply more? Now you are going to burn up your lawn with the excess fertilizer. Keep it separate and things will be more simple.

It seems to me that good herbicides will be applied in liquid form (not weed and feed) and good fertilizer will be in pellet form (not Miracle Grow Lawn food).

Texas is big but I'll assume your spring weather is not fully under way yet. In other words, your grass is still mostly dormant. You may have brown spots now but it probably will get filled in.

I wonder if the barkless trees might be crepe myrtle?

Texas is very big. I have three houses (anyone want to buy two of them??) about 150 miles apart and they are clearly in different phases of springtime. One yard never went dormant while another is still in dormancy. If you live in Brownsville, you have spring instead of winter. If you live in Dumas, you have spring instead of summer. In other words, we really need to know where you live.

You should decide right now whether you want to have bermuda or St Augustine. They can coexist, but it will look weedy. Or you can start catering to the St Aug and it will easily stomp out the bermuda. But neither one will thrive with dollarweed and/or clover. Most likely your "clover" has yellow flowers about now. That's not clover, but it's a weed that will keep either bermuda or St Aug from filling in. Decide which you prefer and we can help you eliminate the other one. You won't need chemicals either way. Don't overseed anything until you have decided. And if you decide on bermuda, again, don't overseed. If you have thin spots where the bermuda should be, then you have shade issues and no amount of seeding will solve that. And if you decide to overseed the bermuda, you have to wait until June anyway because the ground is not hot enough yet to sprout bermuda seed.

Before you buy a herbicide, you need to know whether you have Floratam St Augustine. The blue bottle pictured above will kill Floratam. For floratam you need the black bottle with purple labeling. But don't get that until you know what you have. Floratam usually has purplish stolons running across the surface of the soil. But another precaution is that most St Aug will develop purple runners in the winter. So wait until the grass is growing and you have mowed it twice before checking.

I also suspected the barkless tree was a crepe myrtle. If it is not putting out leaves yet, then you must be in Austin or further north.

Whatever bugs you have, ignore them until you can describe them to us. Photos work great for bugs. By far most bugs are beneficial, so you don't want to go spraying insecticide on everything. It is better to go by what issues you might be having. Are you seeing bugs eating plants?

If you decide to post pictures (recommended), try to take the close-ups on a cloudy day and the distance shots on a sunny day. If we are looking for shady areas, then we need sunlight. But close ups always look better with no direct sunlight.

I would rake the leaves out of the lawn and make a compost pile if you don't already have one. St Augustine does not like to be kept wet on the blades, and those live oak leaves can do that. Or you could pile them up as mulch in any flower bed to help keep weeds out. The grass in the second picture is poa annua, a bothersome weed that will die from normal heat anyway, only to return more dense next spring.

If this were May (or you lived south of San Antonio) and I saw those yellow spots on the grass blades, I'd be concerned about disease. For this time of year, north of San Antonio, that is fairly normal. Really need to know where you live to be more helpful.

Crane flies are not a lawn problem in Texas. Did someone tell you they were? Maybe if you had 10s of thousands of them, then I'd get concerned. The crane fly larvae lives in compost piles or moist mulch. Then they "hatch" into adults. The adult has no mouth so it never eats. It does mate and lay eggs. Then it dies in 10-15 days. In a month you'll never see another one until next March.

Have you decided whether you want to keep the bermuda or the St Aug?

Where do you live?

I guess I will stick with St, Aug, as that seems to do better in the shade and there is a lot of shade between the patio and the pool. I do clear out the leaves every week, but if you have a live oak I am sure you know that right now it is impossible to keep them entirely clean unless I pay for a daily lawn service. And for clarification, I live just outside of Dallas. I am hoping that just fertilizing, watering and mowing will help my lawn fill in and overtake the weeds.

Will the crane flies die off, or will they be around all summer? I know they don't bite, but every time the door opend a dozen of them fly in and I spend 30 minutes chasing them. I am also worried about mosquitoes and looking into something that I can spray myself (perhaps from one of those haldheld three gallon sprayers that the pest control people use) to keep them at bay.

Although if you'd like to give me a standing ovation, I certainly wouldn't object.
