I am back with more questions. We watered the seeds and newly grown grass for at least 2.5 months 2 times almost daily last year. Timing varied based on conditions from day to day. As you menitoned, most of the grass died in the hot summer and weeds took over, especially this 'small crab grass'. It spreads with rhizomes and the seeds grow on tall stems and are tiny. The grass part is tiny as well, however I can't figure out what this weed is exactly called. It grows in shade as well and most of it's main root base won't die in the Winter. We had few regular grab grasses and some other weeds as well. We did not reseed in fall due to sudden freezing & snowing conditions after hot fall weather last year. We did reseed with Damman's mix of KBG, Rye & Fescue and extra of KGB in the worst areas this March 6th. The weather looked pretty good and it rained every 3-4 days really well. We believed the dead grass & weeds would protect the seeds, so we did not rake or do anything to the ground. The dirt was very fluffy, our soil was not stripped in the past. The seed should get washed in with the heavier rain we had, correct? Or not? It is cold this week with freezing tonigt . It didn't rain for a week now. We did not water while it is too dark and cold in the morning and we didn't have the energy to do it in the evening yet. The grass doesn't seem to grow at all, we are getting very frustrated. We realize we skip some details for better grass seeding, however we have to go to work and don't have that much time during the week. We can't seem to make a good choice with the time, it is too cold, too early, it was too hot... And the weather changed so much lately, 4 months of snow with freezing; and it even snowed yesterday morning. Our biggest worries are that the grass from this spring's seeding won't grow anymore and today is the last day of March. We will be in the same boat as last year if the weather will suddenly heat up. I did some hand pulling of weeds last year and these areas look better, however some areas look verry bad - yellow. I am thinking of using Preen Lawn StepSaver Weed Control Plus Fertilizer. Or should we aerate and reseed? We did not put any weed killer down due the new seeds. This is about 1 acre of lawn we are trying to regrow last year's killed grass. We didn't do much with the sloped areas yet due to not having enought time and our right budget. Thank you for any help in advance

We're dealing with the same type of thing in our yard. Spraying it with Roundup and then keeping it covered with black plastic for a season or two helped, though it didn't get rid of it completely. You might try that if it's in a hidden area. If it's in your front yard (as ours now is), I don't know what to do. I've hard that several seasons of Roundup in a row will eventually poison all the rhizomes, but who wants to poison their lawn for two years straight?

I'm in NJ as well and when my house was completed my builder seeded grass with rye/fescue/kbg mix. It didnt fill in that well and I liked the way KBG looked so in the front of my house I kept reseeding with just KBG mixes and the back of my house with rye/fescue/kbg mix. So I think I was exactly in the same boat as you. My front looks great and it was a good thing that it was originally seeded with the mix because there is one area in the back that gets a lot of shade and KBG didnt take there but fescue did and it looks great. The rest where there is more sun fades from fescue to mostly KBG but the transformation from one to the other is unnoticable from the street. My neighbor across the street got his house built after mine and my front yard looks better then his $2000 sod. Now my backyard was originally seeded with rye/fescue/kbg mix and reseded with that as I'm still trying to get it as thick as my front yard. It looks fine but nowhere near as good as my front yard. It also doesnt require the amount of maintenance the front does and it seems to be more resistant to kid abuse. I guess what I'm trying to say its all relative to your situation and what you are trying to do. I wanted my front to be mostly KBG as it looks better but it took forever to establish and it takes more work to maintain. Not a problem for me as a like working on it. The existing mix that was seeded might not be a bad base as it will cover any places that are shaded where kbg wont grow (I dont know your yard so thats really up to you) but it wont be as uniform as the pictures posted by pure KBG owners. Tall fescue stands out in KBG and you will definitely notice it. Now my backyard didnt have to be nice but more drought and abuse resistant. Thats exactly what it is plus it doesnt require as much work. So it all worked out well for me and I got what I wanted. I have nice lawn in the front and decent but resistant and low maintenance lawn in the back. Everyones situation is different and you have to take it all with a grain of salt and decide on your own. I dont know what your lawn looks like now, how much time and money you want to spend and what kind of final quality are you looking for. Either way good luck and I hope it turns out good.

Where are you? The kind of grass you have may vary a lot depending on where you are. If you've got cool season grass, it sounds a lot like most of your lawn is KBG and the wide leaf grass is tall fescue (likely K31). It's very hardy, but not as attractive in a lawn and its faster growth rate makes it stick out. If that's what you have, you could spot spray with glyphosate and if the patches are not too large, the KBG will fill in from surrounding areas. If the patches are too big for that, you could spray a few areas at a time. The problem with killing all of the K31 and overseeding is that it might be tough to match the rest of the lawn (and if you buy the seed at a "big box" store, it may well include K31).
