Long time lurker here. Between family and work, I have neglected my lawn for a bit too long and its looking kinda rough. Its obviously very late in the season, but looking forward, I want to set myself up well for next year.

I am located in CT (06478 to be precise).

The yard is 1.5 acres, probably 3/4 acre lawn area. Attached are pics of some common weeds/crab grass that I have.

To get a jump on next year, should I worry about fighting the weeds now..? If so, what is the best weed killer I can use..?

For fertilizer, I spread some milorganite in the spring and fall. I hope to get around to a soil test in the next couple weeks to see what else I need, like lime etc.

I'd rather not pay a pro, but am open to the possibility, just don't know how to find someone worthy of my hard earned money.....

In my area at least, it cost me the same if not less to have a service come out and fert/treat my lawn than I can do it myself. Plus I dont have to take the time to do it so IMO im coming out quite a bit ahead. You can get free estimates on a lawn fert service or ask your neighbors or friends if they use one.

But if your just looking for what to do, Scotts has a good site filled with lots of great info.

Several of my neighbors use the local Lawn Doctor office. Their lawns look great, few if any weeds, god color, etc. But from conversation, I know the Lawn Doctor guy doesnt do soil testing. They are just on a "standard" program. I figure if I were to learn as much as I can about doing it myself, then I'll have the choice to either DIY or hire someone, but I'll have the knowledge to know if I am getting good service from....

I let my lawn appearance tell me the job my service provider is doing personally.

This is the best time of the year to spray broadleaf perennial weeds... the reason for that is, all seasonal plants that need to survive the winter begin to store foodstuffs as the days shorten and the weather cools down...

Be sure the moisture level of the soil is adequate, the plants are not stressed, but happily growing and they'll suck in that poison like a glass of Kool-aid...

For the CG,,, just toss some seed on the areas where they freeze off and you'll have their dead bodies as cover to get them going...

Looks like CG to me and the others look like broadleaf perennials... the recommendations for post emergent control for those weeds are herbicides like 2,4d... if they're perennial, they need to be sprayed... :)

Isn't proper identification the best way to ensure proper treatment..?

Broadleaf vs grassy leaf IS your proper identification when using herbicides... some claim that Dicamba is better on Creeping Charlie than 2,4d or mecroprop,,, but generally All 3 are combined together to make the product... :)

From what I have been reading on this forum, if my second pic is indeed Stilt Grass, Acclaim Extra seems to be the recommended treatment. For the other broad leaf weeds, I think you are right, there are many herbicides that will do the trick, and a blend might be the best way to go....

I did get a quote from the local Lawn Doctor, he actually took a sample of the offending grass and got back to me just this morning, he also came to the conclusion it was Stilt Grass. Said he had a product that "might" take care of it, but no guarantee, I plan to ask him for the name of this product...maybe its Acclaim..Other option was round up and re-seed.

I had previously mentioned a concern about over-seeding without an irrigation system. Seems we've been going through some relatively long dry patches, and my yard is just too big to handle with hoses...We are also getting a bit late in the season I think. So he recommended doing a couple of ferts this year and get full time on the program with pre-m, etc in the spring.

So I think I'll start, it should help with most of my problems anyway. We'll see how the next year goes and then re-evaluate.

I don't know what "Stilt Grass" is but it looks like CrabGrass to me... does it die in the Fall with Frost???

Overseeding is no real problem w/out irrigation... You can put the seed down now in the aereas you want to thicken up and the seed germinates when it is ready... just because it doesn't come up in 2 weeks or less doesn't mean its not coming up at all...

The last 2 years in a row we had a dry October, so most of the Fall seeding didn't brighten up the November landscape,,, however I applied the Dormant seeding, around the time of the ground freezing and the first snow and I had a great Spingtime greenup as a result...

Put off your Pre-M, until your new grasses are mature enough to handle it... :)

So you're saying pic 1 and 2 of the original post are the same? Just crabgrass? I'm no expert, but I comfortably assert they are not the same!

My Thoughts On the Weeds:
1. Crab
2. Stilt
3. Oxalis (clover)
4. Creeping Charlie
5. Wild Violet

If you are really antsie about the crab grass, you could spray it with a herbicide containing quinclorac (contrary to popular opinion, I have had good luck with the Weed B Gon Max w/crabgrass). I let it die and then pull it to open up soil for new seed.

For the broadleafs, given the type you have, I would actually lean towards a tryclopyr based herbicide. I had better luck with it than a 2,4-D based. They are relatively hardy, so I would treat it and then retreat it 10 or so days later. Some clovers and the creeping charlie has a waxy layer that needs to be broken down for effective treatment so I think re-treating is key. They die a slow death so it can be two weeks before you notice them dying off, but they will die.

For all other broadleafs, a blend of 2,4-D, MCPP and Dicamba work well. I usually keep two products on hand for weeds, a Triclopyr Based and a 2,4-D based. I prefer the concentrate so I can tweak the concentration at use a little depending on the weed. Weed B Gon products have worked fine for me.

These are my un-professional opinions that I have developed from reviving the lawn that came with the house we bought last fall (in other words, it is what I have tried personally). Unfortunately, I have learned more about weeds than I ever wanted to this spring/summer.

I had started the year spot spraying weeds as they appeared with things like weed-b-gone. Worked great on things like the pink clover, dandelions, etc. I usually mixed it up slightly stronger, and treated twice, about a week apart. Didn't touch the creeping charlie. It also doesn't seem to afect the weed int he last pic, red wood sorrell I think.

The crab grass is annoying, but I know it will die back and I should get good control if I can start a good preM program in the spring. The japanese stilt grass in a bit concerning, mainly because i wasn't completely sure thats what it was.

I am going to start with the local lawn doctor, he seems to be saying enough to make me feel he knows something about maintaining a nice lawn. I am not expecting drastic results with the crab grass or stilt between now and winter, but hopefully I am setting myself up for a better lawn next year...

Get a different broadleaf mixture and hit the CC in the Fall... this is the best time of the year to take out the CC... I still haven't seen your stilt grass, only the CG appears... I'll have to page back and try again, but is it a perennial grassy weed???

Hmmm...there are 5 pics on the first post....not being able to see them has gotta be confusing..haha

Stilt grass=Japanese Stilt Grass. Its an annual I believe, considered an invasive species in 14 states.....

3. Yellow woodsorrel aka oxalis
4. Wild violet
5. Creeping woodsorrel

All 3 of these weeds will be better controlled with a broadleaf combination containing triclopyr. Violet might take multiple applications still. Look for Ortho Clover, Chickweed, and Oxalis Killer (CCO). It is straight triclopyr and can be applied alone or combined with your other weed b gon mix.

1.) Crab Grass (or any other weed grass)
2.) Asiatic Dayflower. Good luck killing and controlling that one.
3.) Clover
4.) Wild Violet
5.) Black Medic while still a bit green.

3 and 5 are definitely oxalis varieties. You can see new and spent oxalis seed pods in the last picture. Not clover or medic.

#3, does this have a common name? I have some old memory of another name...and being told its edible? Maybe I was just a little kid eating grass..? haha

You have a couple of noticible difference

2. Asiatic dayflower vs. Japanese Stilf Grass

I googled asiatic dayflower. I can see the similarities in the leaves, but I have never seen mine flower. Certainly int he middle of the yard where I mow, it gets cut too soon. Its invaded some planting beds too, where it can grow significantly before I get around to pulling it, and still havent noticed any flowers. Next time I am out there, I will be looking for them though.

5. Balck Medic vs. red/creeping wood sorrel.

The leave of the black medic don't loook very "heart" like to me. Nor have I come upon any pictures with color like what I see in my lawn.

I too still eat oxalis to this day for the sour/bitter flavor. Then I kill the rest with triclopyr. I don't recall any other name for it though.
As for the creeping woodsorrel pictures, search purple creeping woodsorrel and you should find plenty of options. Oxalis corniculata Vs. oxalis stricta(yellow).

Did notice the leaf pattern after you mentioned it.

As for the Day Flower Versus Stilt grass, the leaf in your picture looks more like the day flower to me.

But, I'm not there to make an up close judgement on that one.

This might help your diagnoses though.

And, if you haven't seen the flowers at all or yet, it could possibly be deer tongue grass.
