New chick learning all of this as my husband has Young Onset Alzheimer’s and he took care of this stuff. Nobody told me it involved math! Lol! We have a very odd shaped big back yard and small front yard so hopefully after this video, I will “get it right”. I had hired a lawn guy last year and watched him put a few products down with a spreader.I saw my husband had one and asked someone how to apply which products to our lawn and when. Since lawn guy I tried wasn’t really honest, I felt I’d be wasting my money so I am learning to do it myself! Thank you for this video!
Good luck! You'll do great
Under Construction is an obstacle that reduces the importance of the lawn. Pushing 90,000 sq.ft. I plan to just mow until August, then nuke the grass that is there. I plan to sow a stand of KBG shortly after as fall grass seems to be less labor and expense battling the weed pressure. On the fence about an irrigation system as 2 acres will be a small fortune. Great Vidya Ryan. Great production and detail. Cheers.
I will have to look into that. Last year I watched your video in weed be gone that I used to spray on my lawn last summer and it worked. It got rid of all the clover and other weeds from my lawn
Yeah those products are cheap but work well
Tony Madera same thing here his advise was spot on got rid of all the clover in my lawn thanks Ryan
I'm watching this a week after I just applied my first step with pre emergent and realizing how many things I did wrong! Thanks!
And next time you'll have everything right :)
Buying a spreader and throwing down pre-emergent and fertilizer for the first time ever this week. This video and the project lawn series from last year have been super helpful. Thank you!
Awesome!
I think its easier for me to control the N and prodiamine output if i do them separately. Liquid pre em followed by granular fert a week later. And i love the tip about putting extra fert in spreader. Badass bro. Never even thought of that.
I like to control separately most of the time as well...but there is a time and place for N mixed in for neglected lawns. Thanks for watching!
Project lawn that is 80,000 sf had my interest. I have a larger lawn that I recently renovated. So many videos on RUclips are geared towards smaller lawns and some of the methods aren’t practical for large lawns as you mentioned in the video. Keep the updates coming!!
Thanks again Ryan, I’m in central Minnesota and followed your videos last year, but couldn’t get rid of the crabgrass. I was hoping you’d put together a video for pre emergent on crabgrass. Soil temp is 45 degrees here, so I’m a few weeks behind you, but will follow your steps!
Ryan I appreciate the vids. The hubby thinks our lawn is looking better every year. I still struggle with spreader rates and how much I put down but I'm getting better. I live in the DC area and have a clay based lawn. Lordy the struggle is real. That clay in the summer is rough on.the lawn. And I have 3/4 zoysia on the front lawn and cool season fescue/bluegrass on my back yard. I literally have a bi-polar yard.
Thanks for using Scott's Elite Spreader. I bought one last Summer and there is not a lot of information out there on them.
Hi Ryan.
I have a question.
I reseed my lawn the last week of August and the grass looks pretty strong now, do you think that I should apply crabgrass pre emergent? Or should I wait till the next spring.
Thanks in advance.
Could you please go over the the rates for the powder prodiame for the back pack sprayer
I look forward to seeing the project lawns this year
Great video.I thought you had a sprinkler system installed last year. Why don't you use it?
Great video. Watching it rain now and like damn, my forecast doesn’t have rain in it either!
Can't wait to see that giant lawn become a lush deep green color
Mother Father! Great episode. LIke these project lawns...
Man that second project lawn is an absolute behemoth! looking forward to the progress. You'll get it right... all in time!
Maybe 5 years haha
Doc did a video like this recently. Basically set the spreader to 1/4 of the max opening and use that as a starting point. Made it really simple as I started weighing everything this year also... like a good lawn geek lol
You have to wait a couple weeks before you can overseed after using this stuff right? That sight says soil temps are reaching 60 here so I feel like I'm too late...
It would be months before overseeding...usually minimum 60 days
If we overseeded about a month ago, when would you recommend we should put down the pre-emergent?
Great video Ryan! The prill size sure makes a difference on spreader settings.
Brand “S” may be smaller and the herbicide sticks better to the weeds where brand “L” may be larger and doesn’t stick to the weeds then jambs the spreader open.
Definitely a learning process and your videos do help no matter where or what we’re working on.
Happy Easter and stay safe during Covid 19.
Very very true...calibration is the way to know for sure
Glad you emphasized blowing the fert off the cement. I see so many company’s just spread and go.
Not a good practice
Hi Ryan, what is Foxtail ? Because I have a weed ?/ grass thing that grows in bunches that if left to get tall will make fuzzy things on the ends, nothing will kill it. Please help 🙏
Can I apply in summer time ?
Crabgrass starts germinating once temperatures reach 50-60’s that’s why it’s only recommended to put down in early spring I live in NY. And I’ve put down mid February when temps break if we get snow eventually snow melts and any left over crabgrass fertilizer will soak into the soil giving you an early start on lawn care especially if you want to squeeze in a spring overseed in between fertilizer applications
I was starting to wonder about your project lawns.. Thanks for the update Ryan!
Great video, Ryan. Really looking forward to see how that large product lawn responds. Thanks.
80k sq ft is insane! Sorry to marker dye on your seat right at the end. Good luck on your project lawns this year.
Man, that huge lawn looks like a lot of work. That would be quite an accomplishment to get that thing looking good. It'll be interesting to see how it looks in the fall. I think I would just cut it in half and figure out something else for the back of the property like trees, plants and grasses. Thats work too for a number of years but once you can get it established its mostly maintenance free. Also, that's a dream property for someone that is into growing food. Unlimited sun and more space than you would ever need.
I use a LESCO Dithiopyr product. No spreader settings but it was easy to figure out & find what setting works for me. Afterwards I wrote the setting number on the bag.
Glad you showed the before shots on the big project. I was feeling a bit ashamed of my beloved super turf 2. That yard is a monster of a project though, and has come a long way.
Same brand of fert I get from my local place landscape supply. Decent prices for sure.
Thank for the video. Excited to follow with your other projects.
Great video Ryan, looking forward to seeing that project lawns results!
Hi Mr. Knorr! Been watching your channel for a while and I want to say , thank you for all the tips ! Amazing work ! I do share the passion for my loan so I want to see if you could share tips for people in Mexico ! Truly appreciated! Where to buy ? Types of grass ! Everything
My lawn service put down my pre-emergent a two weeks ago but I'm seeing some crab grass growing near the edges of the yard ... should I be pulling this stuff out by hand while I can still see it before cutting the grass for the first time or is there something I can spray it with to kill the stuff which survived?
Looking forward to the project lawns and whatever else you have planned for this year!
So many plans down the tubes right now...but I'll think of something :)
@@ryanknorrlawncare Yeah I bet. Hopefully soon we'll be in a much better situation.
Question Ryan, on your warm season lawn care guide in the nitrogen section what does the 0.2 and 0.8 decimals stand for ? Thanks for the reply !!
How would you compare the Scotts lawn products to what you get at the turf supply stores?
Ryan what spreader would you recommend for a smaller size lawn 5000 sq ft?
I was thinking to put crabgrass preventer and Scott’s starter fertilizer bag at the same time. Is this ok
I really liked your explanation on the spreading settings and weighing material out. It's an extremely similar approach I have. Well said.
Great work Ryan keep up the great video's
I feel like the 25N in my locally popular pre emergent requiring the two apps really prevents me from getting on a regular feeding schedule. Add to that spot seeding, over seeding, etc. and it’s actually a handicap. I think I’ll be switching to non-fert pre emergent.
Hey I enjoy watching your videos and learning how to properly grow my grass and take care of it .
I personally have no grass in the front or the back of my home .
So I was told to used the Scott Halts crabgrass preventer , but no idea when to spread grass seed ... any idea ???
I google the answer but not a persistent answer one says 6weeks another 12weeks
Is there something you recommend that’s pet friendly and for existing weeds? Something like a 3 in 1? I’m a little late to the game as far as preventing them from growing for the year.
Love the Award brand of products.
Definitely need to see more of the large project area!
Also I purchased the pdf book the other night. Will be printing it out soon to have a physical copy to have for reference
Hey Ryan, im in southern california and put some fescue down 3 weeks ago it was overseeding and looks great, about to cut it tomorrow..there are like 2 spots that look like a cat digged in and didn't grow, how can i fox that? seed again in those spots or give it its 1st cut and wait?
is there any way you could give us your input on controlling moss? Like more of a prevention and of course killing it?
I applied Scott’s turf builder halts crabgrass preventer with lawn food to my yard. After I applied this, I followed up with peat moss. Did I make a mistake by applying peat moss after?
I bought Scott's triple action pre-emergent. Do you think it works?
Brought out the big spreader, nice. Great video.
I just overseed my lawn 3 weeks ago and now I am getting a lot of the crabgrass. How long should I wait to use tenacity? Thank you.
May be wrong based on a quick google search. Tenacity can be used at seeding. Otherwise should wait until it has been mowed twice. Sorry for confusion.
Hey Ryan .. I applied Scott’s turf builder crabgrass control and after watching this video realize that there is a lot of nitrogen in that product and it shows the grass grows fast .. what product do you suggest for my next application to prevent dandelion and broad leaf weeds?
Info here - ruclips.net/video/-l2cBTlsQug/видео.html
The neighborhood project lawn is looking great. The big project lawn well, that should be interesting. Personally myself I’m curious how that is going to pan out. It looks rough but certainly not horrible. Curious which tall fescue seed you went with because it could also be the germination rate that contributed a little to that random patchiness even near the house which I’m sure was watered. Sun/heat, water, and good seed to soil contact are easy to handle in small chunks. A massive lawn like that doesn’t happen overnight without a LOT of care.
It's high end seed from United...we are WAY ahead of last year in that specific area we were focused on last year so I'll be interested to see how it looks by winter. It all depends on budget which I am not in charge of...haha
Hey Ryan.. So , I live in New Jersey. Its spring time now. Average air temps are around 55-60 degrees. I've done some patch work already (from the dog) , & its germinating nicely. At 1:44 you mentioned that using pre-emergent with fertilizer will cause the grass to grow quickly (as the summer approaches).. Do you have something specific that you suggest? Because I want to get rid of the crabgrass, but would also like my lawn to grow faster. And yes, I mow my lawn myself, & can keep up with the growth. The other thing I wanted to ask you. I have a mini Scott's push seeder. How can I avoid the spreading from spreading too wide of an area? Can I keep the spreading somehow to just the width of the spreader?? Thanks buddy.. Appreciate you..
John
Hey Johnny, I landscape in New York and New Jersey. If you didn’t put a starting fertilizer down when you seeded, I would use 21-22-4 staring fertilizer now. It’s a staring fertilizer, pre emergent, and weed killer all in one but doesn’t kill grass cool season grass then in 6 weeks fertilize again with 19-0-6 dimension + fertilizer to further prevent weeds through the summer. Usually I would reccomend using dimension with fertilizer now then again in 6 weeks but since you just seeded the dimension could interfere with the growth of the seed (dimension is a pre emergent).
@@brendandoherty2630 thanks so much, Brendan.. That's very valuable information.. And I'm taking it to the bank!! Lol
How about for the "little guys?" How to put down pre-emergent for small properties (1/4ac)? Liquid or pellet? Thanks.
Hi Ryan, great advise on pre emergent. I am in Nova Scotia,Canada. Temp is still around 40-50 deg. I want to overseed soon. What comes first, pre-emergent or overseed. I usually cover my seed with some Peat moss. Will that defeat the purpose. Cheers, Greg
Well said Ryan. It’s easy to see what the bag says, but there are those times when the bag doesn’t give spreader settings, and you freak out.
This is early September I live in Hewitt Texas I have crabgrass I was wanting to know with my saint Augustine grass what is the best pre-emergent did I can put down that's granular
Great video Ryan. Was able to get some work done on my lawn over the weekend by following your Complete guide. Looking forward to the results and hard work! Thanks again for the content you're providing.
I really wanted to use that Scotts crabgrass preventer here on my lawn in Europe. Unfortunately it is not available here. Any ideas on good alternatives here in the Netherlands?
Great video Ryan! You have been a great guide through the spring season. Soil temp is 50 degrees here in Indiana and the crabgrass is already present in my yard. Should I go with this pre emergent or look at post emergent solutions? I made the error of already putting down overseed/fertilizer!
crabgrass shouldn't show until mid summer so I'm betting it's something else
That huge lawn is going to look nice when completed. Thanks for another great video.
I'd like this guy as my neighbor 😊
Ryan! You didn't talk about your Elite spreader! Do you like it? I got one in the off-season and really like it so far.
Yeah it's good. Works well for my needs and a little more "comfortable" ride than the super cheap one :)
Great and informative video Ryan!!!
What would be a good grass for no shade in Kentucky? We just moved into our dream home and I’m wanting to redo the yard.
I would say it sort of depends on exact location but that's likely transition zone so a warm season grass or Tall fescue for cool season grass
I always feel so torn about throwing down herbicides that impact pollinator weeds, like dandelion. Do you compensate by planting pollinator-friendly flowers or such? I did 2 apps of pendulum last fall because I have a horrible poa problem that makes me wanna pull my hair out and I'm going to use a preemergent this season,, but I felt so guilty that I'm planting a windlflower garden and bought a bee house.
Does it only work before grabgrass starts to grow or can it be applied after
Hey Ryan. I overseeded about 3 weeks ago and I am seeing some pretty positive results so far. Is there any risk to harming the new grass if I were to apply a pre-emergent now? Thanks!
Yeah it has specific instructions on there for when you can apply after new grass and I believe it's a decent chunk of time. Check the label to be sure
Thank you for the video! Something I am confused about is if I wait until soil temps are 70 degrees for the second application (typically late May I think) will I still be able to overseed in early September? Should I just put the second application down earlier to ensure I’m not overseeding less than 4 months after applying pre emergent?
Usually the heat of summer and rainfall breaks it down in the soil but also utilizing core aeration before seeding will break the barrier pretty well if there's anything left
How are you liking the Scott's elite? I'm having issues with the mini edgeguard. Can't decide to upgrade to the elite or an earthway 2600 🤷🏻♂️ thanks for the vid man!
I got my elite spreader at my local Walmart for 45 bucks brand new in box. I used it two times and I like it so far.
I love that garage door! It looks very expensive though.
Good segment. 👍🏼
Do you ever hose out your Scotts spreader? I do and it sheds off rusty water from internal metal near the wheels and bottom. I got a new one and it did the same thing.
Were you calling for your mother at the end? 🤪
Totally understand the marker dye. Kicked over bottle onto my basement floor when putting down preemergent this year. Blue dye every where.
It's terrible stuff!
Thank you for the vids! I enjoy learning from you.
Thanks for watching!
If I put pre-emergent crabgrass preventer down in the spring won’t I have to worry about it affecting the seed I planted in the fall of last year with over seeding?
It depends when it was planted and if it grew in the fall. If it came up and was actively growing then you are fine with pre-emergent in the spring
Would putting prodiamine down interfere with St. Augustine plugs spreading?
I applied Barricade by Andersons on 3/27/21...I'm in NY, soil temp was around 47 and have 2 acres. I bought a Lesco 80lb broadcast spreader(the Cadillac of spreaders imho) and applied it but now 4/17/21 I have crab grass, dandelions and all kind of other crap growing in my yard...am I doing something wrong??? FYI this is a newly reseeded GCI TTTF I bought from Pete which looks AMAZING even with the damn weeds
If I plan on reseeding in fall should I apply preemergent in summer ?
Weeds grow and strive in summer heat so it’s best to put pre emergents down to prevent overgrowth of weeds. It also helps when over seeding in fall you want to make you follow those steps when you over seed it helps choke out weed growth
Thank you for your videos. I'm still confused on knowing the correct math for product application. I have some new bags of fertilizer that I purchased last year at a local seed store that closed. I have 4,000 sqft on the back of my house and 2,500 on the front. The bags of fertilizer say 16-20-5 (50 lbs) and the other 29-0-4 (42 lbs) how do I know how much (lbs) do I need for each area?
At the 8:48 mark: "So you're probably thinking to yourself right now, this seems like a lot of work." Ha ha! Yeah, but that's what you do when you are a perfectionist. I've done the same thing. Thanks for the video.
We perfectionists are all the same... :)
@@ryanknorrlawncare Glutton for punishment is what I call myself :) 👍🏻
Is preemergent safe to use with pets and dogs that run on the lawn. Can it be damaging to their paws?
Hello, I have been binge watching all your videos lol.. We just re-seeded 2 days ago, how long after should we use fertilizer? And our yard is in bad shape with weeds, we are just doing our best to do what we can with it. Feeling hopeless 😩
You can put some on right away if you want...many use starter fertilizer along with new seed
Ryan, I am good on the crabgrass prevention and I am now going into late spring/ summer with large bare spots but there is a lot of ST Aug runners here and there, so I know it will fill in quick. My question, HOW MUCH WATER should I be putting on these areas per week? I have new inground irrigation setup with 1/2" twice per week. Gulf south MS, all St. Aug. pre-ermg is all down for fall and spring, first fert app easter w/e. THANKS
St Aug needs water and 1-1.5 inches per week is typical
Awesome info, Ryan. Question... i live in a similar climate to you (I live in Nebraska) I just applied a half dosage of Barricade (April 11, 2021) granule with my Scott’s Edgeguard spreader and I have a bag of Scott’s Halt Crabgrass Preventer I haven’t used. Can I use the Scott’s Halt later in the season (Early June) as a second application instead of the Barricade? What would be your recommendation? I know Scott’s Halt has Pendimethalin. Will this conflict with the Barricade? Thanks!
You can use either one for your second app
@@ryanknorrlawncare Thanks, I appreciate the suggestion.
Any particular reason you choose Prodiamine over Dithiopyr?
See, always checking to see your latest videos lol! Now I have a pretty good question I think... “ if you have a sand based soil 80/20% , does it make sense that you can safely go over recommended fertilizer rates because it doesn’t hold as much and drains much faster, so you can fertilize more frequently?
You want to stick to recommended rates but may need to fertilize more often...the recommended rate is there to make sure it's appropriate for the lawn and doesn't cause any damage
Ryan Knorr Lawn Care So stick to recommended rates but applying for frequently makes sense? Just to be clear.
Excellent video man. Excellent!😎👊👌
You mentioned prodiamine not being great at broadleaf prevention like dandelions. Have you ever mixed in isoxaben as an extra preemergent for broadleaf weeds? I know it's usually associated for use with broadleaf but I don't know for sure how effective it is.
Hope to be trying that in the future
Hey Ryan. Great videos! I need to over seed my lawn and grow new grass in some areas where I installed trenches for landscape lighting last fall. I think I put down my seed too early. Because I haven’t seen any of the seeds germinate yet, and it’s been two weeks now. When should I put down seed? I live in southern New Hampshire. Thanks Joel
It's probably still too cold. Wait until things are warming a bit more and if nothing is coming up..seed again when the soil temp comes up to around 60
Do you have any good tips for getting rid of quack grass in northern minnesota with Kentucky blue grass and fescue lawns?
Get that bluegrass and thick as you possibly can and it may start to choke it out...otherwise you are down on your hands and knees painting the quack blades with roundup...not much fun :(
You can't seed for quite a bit after prodiamine right?
Awesome, just what I was looking for!
I'm having problems with dandelion, any suggestions? New subscriber. Thanks for your videos!
Videos comes out tomorrow :)
@@ryanknorrlawncare thanks for your videos, love them!
What do you think of Jonathan Green lawn applications?
You mention the clay soil...my entire yard is garbage. What can I do to better the soil and therefore have better grass??
