When Should You Mow New Grass after Overseeding or Renovation

[@TheLawnShark]

This is good information and timely. I was thinking I needed to mow, but was hesitant. This helped me decide to go ahead and mow it. So glad I bought that manual reel mower. Nice Job Nate!

[@PacificNorthwestLawns]

Thanks Dino. 👊🏼 How tall is your grass now?

[@TheLawnShark]

@@PacificNorthwestLawns It's about 2 inches, but we have had monsoon rains for the last 6 days and a lot of it is laying down. Hoping it pops up tomorrow when it dries out.

[@PacificNorthwestLawns]

We got hit with 3 inches of rain over this last weekend. It was nice but I was forced to make the video in the garage between showers. I think it worked out OK other than a little echo

[@popeyeyankee5477]

I'm also thinking about cutting the lawn a litter shorter. I usially cut it shorter for the winter, but during the growing months my deck height is at the top setting. I'm not sure what height i should have it, but I feel like the long grass blades are matted down, espicially after striping. I feel like the matted blades are blocking sunlight and water from getting down to the soil. Thanks.

[@PacificNorthwestLawns]

@@popeyeyankee5477 what type of grass?

[@driximus]

Started reel mowing also on my first few mows this fall renovation.

[@PacificNorthwestLawns]

I see the attraction with it. It's interesting to mow with a reel. It's just not my thing. I did it for the first few weeks then went right back to the rotory.

[@kathyjankusky9870]

thank you so much! we have invested a lot...this is our third attempt bc ppl who did the work before used wrong dirt or wrong seed...so far the new grass is looking great but dont want to do anything to jinx it...great tips 😊

[@johnpham7138]

Thank you for addressing this. I was worried of walking on the grass lol.

[@anthonydickman757]

This is exactly what I wanted to know when I jumped on here. Thanks Nathan it’s perfect timing for my 2” tall PRG reno. I’ll be on the push reel in a few days thanks to your confirmation. And if we get to 80 again like it was North of Seattle today it will be just fantastic! I appreciate all of your guidance neighbor 🙂

[@PacificNorthwestLawns]

The weather forecast down here on the south end of the state looks really ideal over the next week. Hopefully it'll be the same up there.

[@PrincessCutLawnCare]

Great advise Nate! Been out there every other day cutting the new grass 😃

[@PacificNorthwestLawns]

I've been doing the same and I didn't even overseed.... 🤣👊🏼

[@brandonhyden9454]

Aerated leveled overseed yesterday no germination after 24 hrs. Man maybe tomorrow 😂. Good advice Nate. 🤜🏻🤛🏻

[@PacificNorthwestLawns]

No germination yet?? C'Mon 🤣🤣

[@yoko180]

For my first mow I used a rotary and bagged the clippings so there would be nothing sitting on top of the soil if I needed to reseed which I did.

[@PacificNorthwestLawns]

Clippings break down really quickly so you could have done it either way.

[@jamzach4]

So good Nate ! Great info brother, and perfectly explained.

[@PacificNorthwestLawns]

Thanks Scott! 👊🏼 How's it going at your place?

[@vince3871]

I put down seed 3 weeks ago and I’m well pleased with how it turn out but I m seeing some patches were some of the seed didn’t come through, should I wait to spring to reseed those areas? First timer doing this but being here in the northwest near Seattle I appreciate your videos

[@PacificNorthwestLawns]

I'd go ahead and put more seed on those spots now. It's not uncommon to have a few spots that need a little more seed.

[@lisah6076]

Beautiful green grass

[@glin930]

I just did a full lawn renovation (tall fescue seed) 8 days ago. I just got a Scotts 20” reel mower … so using 1/3 rule I will wait until grass is 4.25” tall to do the first mow because my Scotts mower is at 3” cut height? Am I correct? Is it ok to leave grass clippings on the lawn? Thx for making this video…

[@PacificNorthwestLawns]

That would be perfect if you're cutting it at 3". I leave the clippings. Doesn't hurt anything. They break down rather quickly

[@Chi-TownToon]

This video was very informative. I've been very hesitant on if I'm ready to hit with my new fiskars real mower. I'll be out there tomorrow cutting!

[@PacificNorthwestLawns]

Just be careful making turns. Pick the fiskars up to make turns if you can. You'll be fine.

[@rosemessick4742]

We have dead spots in our lawns, and put grass seed in those bare spots and when should we mow the lawn so as not to waste the seeds that have not taken root yet?

[@lysawy82]

Overseed here , TTTF in Northeast. Germinated at day 4 mowed at day 14 3" height , made a mistake using starter at seed down , should wait till germination.

[@PacificNorthwestLawns]

I don't that that's a mistake really. It works either way however. 😎

[@carlom9710]

Another awesome video Nate,today would be my 3rd cut after oveseed.Cant wait,stupid day job.hehe

[@PacificNorthwestLawns]

Awesome! Thanks for watching 😎

[@W4M-o3d]

Just the video I was looking for! Wondered about the first cut and then over seeding. I think my first cut wasn’t Low enough and some of the over seeding has not yet germinated. But it’s looking ok. I just wasn’t sure when to cut because I didn’t want to disturb the new seed. The first cut grass is now 10cm or more long. But might wait these next 6 days of work then I’ll cut. Hopefully the new seed will have set in. Thanks for the video! I’m going to look for the manual cutter now!

[@LawnNOrder]

Great info Nathan….this will help a lot of people.

[@PacificNorthwestLawns]

I hope it does. Thanks bud 👊🏼

[@troubledseed]

Ya I was going to wait roughly 2 weeks from when i over seeded but we have had such good weather and rain for grass, plus I have been watering the lawn too. I think its time now. its been over 11 days.

[@PacificNorthwestLawns]

If it feels right, go ahead.

[@troubledseed]

@@PacificNorthwestLawns I definitely will thanks for the advice!

[@colmortimer1066]

I over seeded about a month ago, I cut everything rather short as you said here, but it has been unseasonably cold here in Missouri and the seed has not really taken off yet..but the old grass is starting to be wanting mowing. I don't want to disturb the seed any, Also the tallest parts of the lawn are a few patches of weeds I seem to have to spray off every year. But I am a little nervous that the weed killer might interfere with the new grass. Of course the weeds popped up in the more bare spots where I was hoping the seed to take over first.

[@PacificNorthwestLawns]

This is exactly why you shouldn't overseed in the late winter or early spring. Fall is always better.

[@colmortimer1066]

@@PacificNorthwestLawns The local lawn center made it sound like dealing with the problems around the end of February was better than waiting until the fall. I was hoping at the worst case I could get something established especially on one hillside in the front, where it is mostly dirt dead grass and weeds. Then maybe add a bit more in the fall to any problem areas left. I was looking it up, and what I have is called Purple Deadnettle. I think I need to get rid of it if I can, without harming my seed, so the grass can fill in some, then put down a pre-emergence in the early winter to stop it from regrowing.

Great tips, Nate!

[@PacificNorthwestLawns]

Thanks Kyle 👍🏻

[@greenM1221]

On day 4 today. Seeded on Saturday still nothing. I’m sure by Friday I’ll have some germination. I was like that when I over-seeded my front yard trying to baby the new grass and not mowing worried about stepping down on it lol 😆.

Great video. I overseeded my lawn on Sept 2nd and it was cut 2 weeks after. It was growing really fast. After I mowed the lawn it looked like a checkerboard. It looks a little better now, but I'm wondering how often should I mow? Do I go back to cutting the lawn every 3-4 days or should I wait till the bluegrass starts germinating?

[@PacificNorthwestLawns]

The kbg should be germinating by mow. I'd cut as you need to.

[@DD-od5qr]

Hi Nate. So with the reel mowing do you not use the grass catcher for the grass clippings? I noticed you did not use yours

[@PacificNorthwestLawns]

Nope. I just let mulch.

[@jkbaker01]

I overseeded with KBG 6 days ago. I have a couple areas already showing and others not. I put peat on it and wondering what to do besides let it keep going. One area gets super wet from irrigation should I dial it back?

[@PacificNorthwestLawns]

You should only be watering enough to keep it moist until it's mostly germinated. Literally just 3 to 5 minutes of water several times a day is enough.

[@jkbaker01]

@@PacificNorthwestLawns oh dang. Think I did too much? Now make it worse it's gonna rain 2-4" tonight. :(

[@PacificNorthwestLawns]

No, you'll probably be just fine but I'd scale it back a little until it mostly germinates. Then you can go back to deep watering

[@zachdailyfost4433]

Hey buddy I plan on starting a dormant over seed here within a couple weeks, gonna power rake and do some light to medium leveling, soil has a fair amount of movement being as wet as it was for our winter on the east side, its a full tri stand of heat tolerant bluegrass, 2 to 3 weeks for germination, with either a 20inch cali trimmer with a grooved roller or a 27inch tru cut with no roller currently. Would i be safe to mow through my germ period as normal? ( currently once a week as the lawn wakes up)

[@PacificNorthwestLawns]

I don't ever dormant seed. I don't feel it works as well as some folks make it out to. However to answer your question, it won't hurt anything to mow it.

[@NateRuss1985]

When do you recommend applying RGS after an overseed and/or renovation?

[@PacificNorthwestLawns]

At the time of seeding, 3 weeks post germination and 6 weeks post germination

[@luvkay8439]

When should I use my lawn mower again after someone put the netting down for new grass to grow? I didn't put it there. The electric company was doing some work and they messed up the grass so they put seeds on grass and the net. I also saw some kind of metal parts they used to put down the net. I want to know when I can cut my grass again and how to remove the metal part to cut my grass?

[@PacificNorthwestLawns]

The metal things are probably just stakes or staples to hold the netting in place. They pull right up. I personally would never use that stuff. If it were me I'd pull it up right away unless you're worried about a huge rain storm washing stuff out.

[@TheScanzey]

So I always mow with a manual reel mower, I overseeded about 10 days ago. My reel mower does not catch clippings, would you just leave the clippings and rake them in a couple weeks down the line as the grass has really settled in?

[@PacificNorthwestLawns]

Just leave them, they'll decompose

[@TheScanzey]

Thanks for the quick reply, would you say it's an option to always leave them, as long as I mow consistently and never let the grass get too long?

Good video and informative, I have a question regarding first mow after overseeding , Do I mulch or bag ? You think my lawn striper would damage new grass ? I am at 18 days and look to mow soon. Thanks

Unless the grass is super tall I always mulch. Remove the striping kit until next spring.

I’m right now at 4 weeks for new renovation tall fescue, I’m going to try to mow on 5th week. Most of my grass is already 4”, I’m going to cut at 3.5”. I really think 3” is too short for tall fescue.

Cut it where ya like it. I've seen great looking fescue at 4" and at 2.25".

Question....I redid my lawn last fall. Lasted good through the winter, i have bare spots in shade area and i had lots of weeds(i pulled them) i want to overseed asap, when should i start? I'm in camas btw thanks

[@PacificNorthwestLawns]

When the soil (not air) temperatures are consistently above 55 or even 60* We aren't anywhere close to that yet. Probably closer to Mothers day. You can use something like GreenCast Online to monitor soil temperatures.

Do you leave the clippings on newly seeded grass when you cut it the first time? I'm using a manual push mower. It's new so the blades are sharp.

It won't hurt anything as long as it's not in clumps smothering the turf. If you have to, use a leaf blower to break up the clumps and spread the clippings out.
