Fall lawn
 

Moved in to the new house first week of April. Didn't get a shot treating for pre-emergent crabgrass and weeds. At this point what is the suggestion going forward?

Crabgrass killer now, wait until mid October and dethatch and overseed or what.

the sun will no longer be directly overhead (or less and less)
so that a taller blade of grass
has more ability to shade it's neighbor....conserving moisture.

longer grass shades out weeds and makes pulling them easier

Victor , I have Scott lawn service do it . I'm on their cheapest plan .. They are very negotiable .. My plan,, they do a Spring treatment ,, 4 weed and feed treatments ,, and a fall treatment . probably for what it cost me to buy all the crap myself ,, So I get a total of 6 treatments every year and just forget about it .. Get a price .. Ours if you pay up front in the spring you get another 10% off .. I've been here when the guy sprays the lawn and spied .. very thorough and great results .. They tag it so people keep their pets off after treaments and you should keep children off the lawn
.. If I had kids that used the yard I'd think twice about the chemicals and live with the weeds ..

Crabgrass is history this year (almost) so oversees new grass. Next year before may 10th apply heavily preemergent for crab grass.

fert it now and slice seed in 10 days.

My first year of having a buddies lawn service do mine....man, what a difference. I have a postage stamp for a lawn so the cost of them treating it is about $100+ LESS that what I could have done buying it myself. I don't water either....I let mother nature do it. My lawn did turn a little ugly during the real hot and dry times, but my weeds were MUCH LESS. Plus, I have been mowing higher too....makes a big difference. I didn't think the service would make a difference in one year, but WOW was I wrong. My lawn is by no means Fenway like, but it is head and shoulders what it used to be. I almost decided to till the whole lawn and replant or go sod.....glad I didn't.
If you can, have someone come and aerate and over seed. They did mine last week and I already have new grass growing in some of the bare spots.....they even did some spots I didn't care about and grass is growing there too. I would at least do Fall Fert....

Similar situation. Our entire back yard was dug up last fall for a septic repair. Seeded it this spring but didn't fert or preemerg for crab. Germination wasn't even and the crab grass took over.

Now there's a lot of dead crab grass. It's not pretty.

Raven, wtf does that have to do with the question I asked? Yeah I know to cut the grass tall. That's not what I was asking.

Thanks for the relavent responses: mugz, dangles, Tagger, spence

it has been my experience that most lawns are cut way to short making the crab grass take hold
as it has no competition for sunlight was my point.

Grass loves the cold and you can spread grass seed right up to just before the snow arrives because that's how nature does it.

the weight of the snow pushing down on the grass seed makes it germinate and in the spring grass will begin growing right thru thinning snow.

It responds to FIRM contact with the soil which is why rolling it flat like they do on golf courses makes such a difference.
