re: My lawn from hell. How do I fix this?

Be more educated

That yard doesnt look too bad. The first thing you need to do is have patience. That wont clear up in 6 months. In fact it may take 2 more seasons. Do the post emergant per instructions on bag.

Next year, start early with pre-emergant and cut your grass weekly in Feb-March even if it doesnt look like you are cutting anything. This chops the early weed sprouts down, keeping weeds and undesirables from growing further and spreading or getting mature. Late spring, the grass will over take weeds.

Jan-March is when you prevent weeds for the entire season.

That was intended for the guy who said "sail your trailer"

First pic looks like Virginia button weed. We have that shite everywhere and spend a good deal of time each spring killing it off

honestly, that just looks like winter weeds to me...they will all die as soon as the temps warm up a bit. I would just keep them mowed and soon the summer grasses will come out of dormancy and take over for the rest of the year.

if you just want to kill them for the hell of it, spray a couple of doses of 2,4-D...

I'm totally against weed and feed products. Kill the weeds first then feed your desirable grass. When my bermuda is 50 percent green in the spring I apply first round of a high nitrogen fertilizer. Make sure it gets a minimum of 1 inch of water a week, then fertilize again 6-8 weeks later. Make sure you water regularly in heat of the summer, a stressed lawn is more apt to develop weeds. Fall pre emergent of Barricade in mid October to prevent winter weeds the spring pre emergent of Demension in mid February to prevent crabgrass and other summer weeds.

What would you reccomendations use on st aug?

My lawn looked worse than his 2 years ago, it's not bad today after using atrazine/weed free zone and spot treating

I would smoke it with roundup and spread some river sand on it. Let the Bermuda grass take it over.

If you are going to spray a selective herbicide and want to save the lawn, use a mower with a bagger to capture the weed seed heads. Don't use river sand for any of your repairs. It usually has tons of weeds in it.

Damn those prices for spectacle, gonna have to stay with my Dimension,
