- In this video I'll be showing you how to dethatch and overseed a lawn using the Greenworks Dethatcher. This is my second project with this Greenworks Dethatcher and it works great to remove the thatch and keep the existing grass intact. I also overseeded the lawn after dethatching with a little bit of Jumpstart Kentucky Bluegrass to see if we can add a new variety of kentucky bluegrass to my backyard.

For those asking about grass seed, here’s what I recommend - ryanknorrlawncare.com/product-category/grass-seed/
Could all that thatch in my lawn be the reason why my manual reel mower doesn't work anymore ???
Meaning, it can't be pushed for more than a couple of feet before it gets stuck on the grass.
I'll really appreciate your response. And thankful that I found your channel, keep up the good work 👍👍👍
What sprinkler did you use to water your lawn at the end of the video?
This is the video that brought me to this channel, and here I am still watching after over two years.
Excellent review. No attitude. No gimmicks. Good editing in condensing a lot of detailed information. I’ll buy one.
I agree
and some sweet video timing to the music cues 👌🏻
Another great video! Just a note...according to the manual, for the height adjustment, the number at the BOTTOM of the wheel, not at the top, is the height where it is set.
Just ordered the Greenworks Dethatcher and it works great. Well worth the cost. And the cost is affordable.
drops $100 worth of seed, hopes "a little bit of this takes hold" LOL I think we can all relate.
Are you in a 4 season climate?
If you have snow cut low, dethatch fall fertilize then just before snow seed the shit out of your lawn/ 25kg/ 50lb bag and let the snow do the work...then a month or 6 weeks into spring hit it with Scotts Max Green.
@@GrandNational66 I’m in Minnesota, when should I lay down the fertilizer and how long can I wait before seeding? It’s early October now.
@@DirtyJobsGuy1 Scotts fall fertilizer the red bag rotary set to 3.5 on spreader = 2 applications mid Sept mid Oct.
I seed just before snow fall...1st week of Nov..no germination till spring providing it contacts the ground...grass must be short and well power raked.
I detached a couple days ago. First time in a few years. I had enough dead grass to sell a farmer for hay. Wow, what a job!! I rented thatcher from Home Depot. Going to look into buying Greenworks for future.
Bought one of these last fall after seeing your last video and was amazed by the amount of thatch that kicked up. Great machine.
It's a great little tool. I love it.
If you started at the top of your lawn, you wouldn’t have to worry about running over the extension cord every time you finish a pass. I just bought one of these I’m a first time homeowner and gonna do this for the first time. It was very helpful video, thank you.
That’s a long day of work. Best part is the chair, beer, and watching the grass grow 👍
You've got that right!
@@ryanknorrlawncare Or, ... grass with your grass? heh heh heh
Hear the Westie's in the background. Classic "pay attention to me" bark. Love it.
Those are awesome dogs!
Had to come back to this video cuz im doing this today haven't dethatched in 2 years..got my greenworks an your elite perennial rye ready 👍🌱
Thanks for this video Ryan, i now realise i dont really need to cover with top soil after over-seeding as i previously thought
Ryan I purchased the Green works dethatcher and love it. My yard is roughly 5 thousand square feet and this little green monster pulled up enough thatch to fill a full size pickup truck. It never gave me a problem and never over heated. Thanks for the recommendation 👍
Does anyone have a comparison of the Greenworks vs Sun Joe dethatcher? I have seen both recommended in different videos, seem pretty similar
just bought my green works dethatcher and can't wait to test it! thought about trying the sun joe for the scarifier but i was able to get a really good price on the green works. lookin foward to messin up my yard :)
I picked up a dethatch rake for my riding mower, it does an OK job to just drag it over the lawn. A single pass for light thatch. 3-4 passes for heavy thatch removal. I have never used a power dethatch machine as a DIY guy.
Amazing video...great job. Love the care u give your lawn.
Thank you for sharing your expertise....👏👏👏👏
Good video I bought a house late last summer and the yard is awful. I'll be watching lots of your videos for tips.
Thanks for the video. Only tip I have is with a corded mower if you start at the house you won't have so much trouble moving the cord.
lol that aerial shot!!!! your neighbors are mad jealous!
Hey Ryan, loving your videos as well as podcasts- very entertaining and informative! I am in southwest Georgia with 2500 sqft of centipede in front yard and 1000 sqft backyard of new zoysia sod. I just started this year really tackling front centipede to get it where I want it. Back in the spring I overseeded and did a little topdressing. After all that watering for new seed, I had a lot of crabgrass and spurge come in too. I did two apps of Tenacity(post-emerge) and that killed the crabgrass quickly, I plan to use the Spectracide for lawns to hopefully kill the spurge once it cools off here a bit more. I did put down some 15-0-15 +iron after the Tenacity, planning to do soil test in early spring to get a real plan together for next year in terms of ferts. My real question is on what to do first thing in the spring. With all the dead crabgrass I have some large thin spots. Im thinking of dethaching to remove dead stuff, use Tenacity as pre-ermege, put down more centi seed, then topdress with a manure/sand mixture and level as best I can(I have a few ruts from having trees removed). Sorry for long comment, just hoping to get some thoughts from you. Thanks and keep up the great work! I plan to get on the Patreon soon.
Thank you for the video! I plan on dethatching and then leveling my lawn this weekend.
love your vids man, has me super motivated to get my lawn Renovated. THANKS!!!
Just bought a greenworks dethatcher…knew this was then place to go for the 411. Thx!
Professional quality video. Nicely done.
I know I am getting old when I spent hours on Ryan's channel
You did a great job making this video. Great info, thanks!
After watching your video last year on dethatching I bought one from Amazon! Thanks for the tips man!!!
Awesome! Glad I could help. That little machine does a great job for the price.
Have a similar model from another brand. Does the trick (especially for the once a year I use it.) Made my rookie mistake last year and blew out my preemergent barrier with the dethatcher. Crab grass loved me for it.
There's always lessons to be learned and sometimes we just have to do it the hard way.
There is something very satisfying about watching a dethatcher do it's job and seeing the junk come up. You're going to be the single reason I will own one some day! 😁
It's a nice little tool. Thanks for watching!
I've been mulching the last bag back into the lawn. Just spread it around and mow it, but it doesn't even need to be mulched, the lawn can absolutely break this down now. I try to return the last raked thatch because its usually the oldest debris from the deepest layer..
9:51 total domination!
for reals! I wonder how many hours a week he spends on his lawn. Just looks amazing and healthy!!!
That's a damn fine lawn! Putting the Jones to shame!
I was thinking the whole time - "How stressful would it be to live next to this guy?".
I have used one of these for the past three years, I like it better than the one you can rent from the big box stores. The rental one really destroyes your lawn and sprinkler heads if you hit them. You do need to make a few more passes, but lawn work is quiet time for me. Wife and kids leave me alone, because they are afraid I will ask them to help
Thanks for the great video!
I’ going to buy one soon.
Wow, you lawn looks great (compared to your neighbors)! I just purchased my Greenworks Dethatcher. Hoping I do just as good a job like you!
Great video, Ryan….very informative! 👍🏾
great presentation and very easy to understand . thanks a million !~
Great video. I'm about to overseed for the first time, decided after research to go with the Sun Joe dethatcher over the Greenworks, it's on sale today also. I was going to overseed at 2 lbs per 1000 sq ft but now I'm going to cut it back to 1 as per your recommendation.
Just depends on the type of seed and how thin your lawn is so take that into consideration
@@ryanknorrlawncare Thanks Ryan
9:52, that picture says it all. 😎
Brilliant video, thanks from London, England
Love the lawn and the hat Skol
Thanks for the video Ryan, great work.
Thanks!
I have one of these. Does seem to bog down at 3 inches, so I would recommend 2 inches. Take it from me though ... if your grass is trained for 3 or more inches, don't take it right down to 2 and then try to use this ... unless you plan to overseed. Lesson learned on a test patch. Get it down to 2 slowly and allow it to get accustomed to 2 inches before using this. I normally cut it at 2 in the fall anyway and 3 to 3.5 in the summer so I typically use 2-3 weeks sometime in August to get it back down to 2 in preparation for the fall. My mistake was going from 3 to 2 in one shot on a test area and then immediately de-thatching ... yeah, that didn't work so well ... that was an exercise in only the strongest grass survives. Great little machine though.
LOL You definitely have the best-looking yard.
Do you actually hand water all 4K sq foot? And still manage to keep it that green? You sir just won the medal of medals 😂
Those Greenworks dethatchers work great. Just have to take it slow, and give that small electric motor time to cool off. Do relatively small sections at a time and rake or suck up the thatch between sections. I had to replace the tines after 3 seasons, as they tend to wear down. Takes a while to replace them, but I did it over the winter months while I was stuck in the house due to the snow on the ground.
I actually need to add that to my list of things I need to work on soon as I have a few tines that need to be replaced.
Ryan as always your the best thx!
Love your videos! Great content.
Thanks!
I’ve been watching your vids for a while now! I’m in MN and I’ll be dethatching and overseeding next week. I’m using the SS9000 Perennial Ryegrass blend. Thanks for your vids man! I appreciate the work you put into these vids. Footage is looking great!
Great! Let me know how it goes with the seeding. I love that ryegrass.
That bluegrass 😍. I'm excited to see that bluegrass germinate.
Gotta love the bluegrass! Can't wait for it to pop again and then I'll probably hit it with some iron and we'll be striping like there's no tomorrow. Man, I'm a nerd.
I have the same dethatcher and I find starting my runs closest to the place I plug the machine in and working away helps avoid manipulating the cord out of the way some.
Very good tip. I'll make sure to try that next time.
What brand and model is that white dethatcher and where to get it?
Ryan, last year when I did my lawn renovation. I used a blend of KBG which has 25% of Jump Start in it. That variety of KBG really germinate fast. Took like 1 week... ! Nice Job !
Nice! I will be at a week this Wednesday.
Can you do 1/2 pure midnight blue and 1/2 jumpstart? What's in jumpstart?
jumpstart is a cultivar that is supposed to be one of the fastest germinating types of kentucky bluegrass. Most take at least 21 days otherwise.
Ryan Knorr Lawn Care that's true up to a month if you use Lowe's brand.
Stay away from the KGB 🤣
Excellent excellent thank you.
6 weeks ago I decide my lane needed much help and work. I found you and getting ready to go here.
But
Aeration? 20 years of no care just cutting.
Must amd will be thatch.
Is aeration critical to start with in this lawn makeover?
Thank You Ryan
Scott
I bought the same machine 3 days ago. It does work amazing. I then went over my lawn with the lawnmower but it didn’t really pick up the thatch. I got one bag collected. Next day the lawn looked dull. Lots of leftover thatch was sitting on top. I ended up having to rake my lawn and got another 2 bags!
Any reason why my mower didn’t pick it up? What did I do wrong?
Great video, good job
did both today even put down starter, hope its not to late its oct 14
Love the beats on this vid.
beautiful lawn man! Looks like my neighbor's lawn except he doesn't' allow his 3 young kids to
play on the lawn.
I am sold on a dethatcher! I have about the same size lawn you do and just tried doing it by hand...forget it! After two hours I wore my shoulders out and barely did an eighth of the yard. Checked them out at Lowe’s, same as yours for $115. Getting it next week when the unit arrives.
I think you'll be pleased how well these little machines work and are very easy to use.
Hey Ryan! How often should I thatch my lawn? I just bought and used a pull-behind dethatcher to my midwestern lawn two weeks ago - the first time in 10 years. Is this a seasonal task? Does it depend on how thick the lawn is? Thanks in advance...
Hi, I got top soil laid down, but has formed into "concrete." Can I use a dethatcher to help loosen the couple inches on top so I can seed?
New subscriber here, great stuff! I bought this machine last year and it's amazing how much thatch comes up when you would never know by looking at it. Great yard you have too 😎
Glad to have you! Thanks for checking out the videos and yes I've been very impressed with the machine.
thank you for the great video
My turf needs to be thickened up this fall, and from what I’ve been reading I need to dethatch beforehand. Should I also core aerate at this time?
Thank you for sharing.
What do you put down after overseeding? Fertilizer? Peat moss?
I just bought this dethatcher on amazon and expect in within a week. I laid down a pre-emergent on the lawn about 3 weeks ago (didn't expect to buy this) - should I wait to use the dethatcher or can I use it as soon as it arrives? Thanks!
Hey Ryan. Should you still water the grass if you have a thatch problem? I don't want to use a power rake until the fall so I can seed in the cooler weather. Thanks.
I hope you realize that if you work your way towards the end of the yard and not towards the power outlet this extension cord will never be in your way.
Good tip. I’ll try this next time I mow my lawn. I’m so tired of tossing the cord out of my way.
I was thinking the exact same thing!
Also, the cord shouldn’t be all twisted up like that either. Maybe a video on how to properly coil extension cords.
I have some burnt patches after using lockup fertilizer spread in the 3rd week of June, I’m going to dethatch with a rake & break up soil soil to weaken the lockup, apply soil, seed & peat moss in the patches apply water, cool season grass perennial rye mix ... should I are areate instead & over seed or just fix the patches
What time of the year is best to do this? I’m in PA, early spring before seeding ? Late fall before seeding ?
Thanks Ryan. When spreading seed and fertilizer do you use the same spreader tool?
I have St. Augustine grass, can that be dethatched with all those runners? Without tearing it up
How’s it work for pulling out creeping charlie?My yard is full of it.
Thanks Ryan! No aeration after power raking? You went right to over seeding after power raking. I live in SW Kansas City, so very similar conditions.
Ryan, I apologize if I missed it in one of your videos... but when purchasing grass seed how can I tell what seed was used in my lawn? I live in northern Indiana so I know I would need something for cold seaons. I just do not want my lawn to have multiple colors (as I have never dethatched/over seeded before). My OCD will be terrible if I have all kinds of greens in my lawn!
Nice b roll man!
Where you reccomend to get some kbg seed ? For Overseeding. My lawn is kbg and per rye mix
I've had this machine for a few years. It works well. All these electric tools are awesome including the tillers. Sucks to drag a cord but you do not need to stop to refill fuel and you can buy them for under $100.
I've been impressed as well.
Good video question when is the best time to do the dethacher. And mi grass is big like 4 inches right know is better cut the grass first or do with the dethacher machine.i live in virginia
I heard the Sun Joe dethatcher/scarifier was similar but overall a better performing machine..Can you do a comparison? Please and Thanks for the awesome content.
Ryan...Live in Michigan..love you channel. just de-thatched...Do you not recommend plugging or slice seeding? Is a channel or hole not needed for the grass seed to germinate? Am I ok with just cutting my lawn low then over seeding?
4:50 Great tip. Thanks! 👍
Will this work with removing moss? Recently got a home and the yard is a mess. I wanna remove moss and aerate the lawn and put down new seed. What would be the best way to go about doing this? Living in upstate it's still freezing weather.
Low setting is 2 or 3 in the spreader? I have roughly the same amount of swft
Best b roll in the lawn care game!
Things have improved a lot since this video haha
Keep it up man! My grass looks great thanks to you lol!!
Thatch also increases your chance of getting fungus and other lawn diseases too
best lawn channel no question. No offense to the lawn care nut
I appreciate that! Lots of great lawn channels out there so I'm glad the community is growing.
Need to buy a dethatcher but not sure whether to go with green works or the sun joe scarifier, opinions?
A lot of the seed that I purchased is covered with a starter fertilizer. Do I still use an additional starter fertilizer?
Could you use an lawn overseeder? It seems as though the lawn overseeder would dethatch and sow the seed at the correct depth in the ground in one process.
How often should a lawn be dethatched during the spring summer and fall?
In which period i can overseed tye lawn? Can i do it in july?
If I am going to detach and plug aerate, do I dethatch first?
Hey Ryan, how do you like the Scotts mini spreader? Im considering one but I hear that product gets trapped in the wheels and leads odd trails.
So you don’t have to de thatch in the early spring before geeenup?
What type of sprinkler was that?
How many square feet is your backyard?
How may times would you have to move it to water your backyard?
Hi Ryan, do I still need to use a pre emergent after detaching?
Perfect timing on the the vid Ryan. Today I de-thatched my 1200sqft back yard with the same green works dethatcher after having done it a week ago as well. It works great! I pulled out 3 full lawn bags of thatch from such a small yard. Overseeded today with some local seed mix and top dressed - hoping for good results. Some spots were really bare so I added more seed there. Just curious how often and for how long should I water? I'm thinking 3x a day for 10 minutes to start - any suggestion?
Yeah just enough to keep it from drying out. That can be different amounts depending on your climate etc but since it's a cooler part of the year that helps a lot as well. Good luck!
Great video.
Thanks!
You’re such a nerd like me, love it ! I ended up getting the Exmark commercial 30 for my PT lawn mowing business and I love it. It cuts through thick grass.
