First off, I've watched a lot of your vids. So today when I was watching Chris D'Elia's podcast and saw your name I nearly choked. Ha, he calls out a comment you left on one of his videos. It's Episode 105 at 35:56.
ha ha that;s awesome! he freaking slammed me but I am stoked that he gave me a pseudo shout out!! I love that dude!!!!
Beat me to it. Good lookin out!
A true Baby, meet you at the log cabin. HAHA @@Thelawncarenut

Thanks for making your plans and videos based on soil temps rather than time of the year. This makes your content relevant for every region.
Can't help but really appreciate all the awesome detailed info you constantly put out for us DIY people. I've learned so much and continue to learn from you even after 4 years. Keep up the awesome work Allyn. Supporter for life 4 sure!!
Just wanna say thank you allyn. Your tips and ideas sure had worked for me.
👍 The videos and weekly newsletters are very helpful for implementing a pre-emergent and post-emergent plan!
Nice job Allyn! Just be glad your not sitting under snow!
For your under-21 crowd (this means you, Jake The Lawn Kid!): Fill a glass with ice cubes, then add just enough water to cover them. Insert manual thermometer and read temperature. Adjust to 32° F, the temp. of ice water. This is how we do it in restaurants. When adjusted, drink the still -non-frozen beer at your leisure.
You're killing me 🤣. A cup of ice water is much easier. Temp is always 32 degrees but I still enjoyed your version.
Just threw down my first ever app as a new homeowner. Scotts turf builder with crabgrass preventer, active ingreient is Pendimethalin. Don't have a clue what I'm doing but I hope it prevents thistles, last summer they were out of control.
Alan, Thanks for all you do the information you provided along with Dic are going to be blended lawn program. Here in northern WV Thank Again.
I have been studying the prodiamine 65wdg 5 lb. I bought way to much I have found! But I live on a lot of land in which I mow. So I just measured some sections and am trying to figure out how much prodiamine to use per gallon. If zone a is 12,239 sq ft and zone b is 12980 sq ft and zone c is 11,050 sq ft and zone d is 1,742 sq ft. Also, I timed my sprayer like you said in one of your vids and did the math. I came up with 1:56 to spray one gallon per 1k sq ft. Thank you for your help Alan, I one day hope to have the knowledge you possess! Love your vids!
This topic is sooooo right on time.
Loved listing to this while cleaning up fallen sticks on the fields in low 30 degree weather. Come on spring! And remember kids to keep your tip and shaft clean.
LCN You can also calibrate using the boil method at 212F. And try to keep your “tip” from bottoming out. Just another method then you don’t have to try to freeze a beer. 👍🏼
Soil temp is right around 29. I wonder what -40 wind chill will do this week? Are you sure you don't want to visit? 😉
Ryan Knorr Lawn Care who’s your guest this week bro?
Yeah and in WI have 4 ft of snow more to come this weekend. seeing 30s the following weekend.
Love ur podcast with him.
The forecast high temp this Wednesday in Chicago is -12 with a low of -25. That is without the windchill.
Love the soil temp talk! I started logging mine past 2yrs. It fluctuates with the nightime lows more than the highs here in coastal CT. Right now 4 inches deep its 32.5°. So frozen couple inches. Last year didnt hit 55° until end of April. (Cold & Snowy spring)
Interesting note, up here in Michigan, Lowes is offering Sta-Green Crab Ex in a blue bag and it’s .38 Prodiamine with a 30-0-6 fert onboard for $45.00 (50 lb/15,000 sq ft)
Love this style of vid Allen! Nice work and really appreciate the content.
So many potential jokes at the end of this one. 😂
Love those drawrings over by der
TIL a 5.6% ABV beer is a "real heavy viscous beer"... You're a funny guy Allen
Would love to see more stuff on Centipede
Sterilize that dirty shaft before you stick it in "O'ver By Der" in my best Allen Hayne voice. Anyways, thanks for all the years of information, joy, and jokes! You keep me going Allen!
sup Alan, just placed an order with you at yard mastery for some prodiamine! thx for the good app, pdfs, and videos!
Glass of ice water then set it to 32° Fahrenheit, give it about 5 minutes then recheck and adjust again if needed. Great video allen. I have a question for you sir. I want your honest opinion aside from what sponsors want you to say. Humic acid(granular) humic acid dg, or humic12 luquid? Thank you sir! Long time subscriber since 2016.
When you put your hands around the sterilized shaft, it's natural that the temperature rises.
Well said, sir. 😂
2020... right before spring weeds germination (feb-march) I put out Scott's "Step One" pre emergent with "crab grass preventer "(pre emergent).. and it completely solved my spring weeds & crab grass infestation I had for many years and just let it go.... St. Augustine lawn, E. Tx piney woods region.... Buy and put it out last week of Feb - first week or 2 of March here..... IT WORKS.... Interestingly the Step 2 bag said not for St. Augustine lawns but the Step One bag didn't hurt my lawn in the least.... in the last week of April after main germination, I put out the cheap Expert Gardener Walmart brand of 'Weed and Feed'... It kicked butt man! only 2 things it didn't kill and they were a grassy type of weed..... For the first time in many years I didn't have a lawn full of little flowers sticking up (Weed flowers lol) or clover and all kinds of salad mix mess junk....
I told my neighbor "You spend all that money on lawn care and you don't have any pretty flowers in your lawn. Look at my lawn, I got all kinds of colors of pretty flowers." He said " You ain't right in the head man..." ha (he's such an ass.......)
You can also calibrate it by putting it close to your thermostat on your HVAC system
Last year I got into your channel and bought my chems...looking forward to this season. ROUND 2
you got this!
Get a Thermowerks Thermopen MK4 that you can use for BBQ, in the kitchen and the lawn. It's accurate to +/-0.7° at only takes 1-2 seconds to hit temp.
My Patience ran out. I drank the beer
Long day at for for me today, but had great and learned entertainment! Many thanks for the tips and walk through at the box store.
All in fun…. I was gonna subscribe until I saw the corona box…. Then you spilled some calibrating the thermometer.
Killian’s Red is where it’s at.
LCNs Ace hardware has the Sunniland weed control for $11.99 at least in my area of Melbourne FL sale is for the month of February
This was great. LCN getting back to his... roots.
LCN....we always used ice saturated water in a glass container and letting it sit for 20 minutes .... temperature should be 33° we use this method to calibrate our thermometers when doing automotive air-conditioning work.
Thank you for doing this with typical big box brands! I literally was looking for what I need to buy pre emergent wondering if the big box store stuff was good enough (not like my yard is that baller... yet).
Great content man, and entertaining as always. thanks for the video!
Is it weird that every time you talk about soil temps at 55 degrees I hear the Sammy Hagar song "I can't drive 55"....haha
Hey @The Lawn Care Nut, ever thought about making a visual calendar for the N-EXT products and such, kind of like DoMyOwn has? It would be a swell addition to the new guides coming out soon.
Just use a glass of ice water. Water starts to freeze or starts to thaw at 32 degrees. Best and fastest way to calibrate.
I think you're missing the humor of the bit.
Nope not missing it. Just trying to help with another why of doing it.
LCN is a true Baby, meet you at the log cabin bro!
I love the empty beer cans at the end and the humour getting a bit cheekier . When are are going to have an intoxicated LCN video ?
I only get intoxicated for live streams
The Lawn Care Nut need to know when the next one is . Us guys in the UK have to factor in time difference
Have you ever looked at corn gluten as an organic pre emergent? It also has some nice fertilizer NPK to kick start the lawn in spring. Just wondering what kind of weed control I can expect vs the chemical options you mention.
I first found the LCN site from your hybrid organic strategy. With small kids running around my lawn all the time I'd like to try organic wherever possible
You mentioned the Scott's Bonus S being pre and post. I have already have some and Wondering when I should be getting that down? In Orlando. Thanks!
Sitting at a steady 42 soil temps degrees outside of BOSTON
Fortunately, you have enough material remaining from Publix to conduct another thermometer test. Then you should test it again to make sure you get the same reading. Try it with and without salt (salt may raise the temperature). Sorry about the cool temperatures in your lawn.
Allyn, on calibrating the Accurite thermometer I thought you said there was a calibrating screw on the backside, but you adjusted the nut instead. Isn't the nut there to hold the probe tightly and it's not to be used for calibration? Also, I would guess that your digital thermometer needs calibrating from time to time too so it won't be reliable all the time for calibrating other thermometers. However, in the soil we are talking "ballpark" temperatures so exact measurements are not critical.
Thanks, Allyn, for this video on pre-emergents and the thermometers. I always learn a lot from you so I am looking forward to your next video/e-mail.
Man goes out to buy fertiliser, brings home beer
Gixer750pilot well he did not want to waste the good beer on his experiment.
Please fill a glass with all ice. Put the temp probe down in the glass. Cover with a kitchen cloth for about 5 min. Go back and the thermometer should read 32. If not then you make adjustments.
I don't currently have access to the recipe for ice.
ya sup Lawn Care Nut. I got your RGS and other NEXT from your site but I feel like I did it again. Warm March is bringing up the ground to 55 degrees so instead of waiting for my scale I just eyeballed the prodiamine. Now I have the scale and see I used to much and I read to much will nullify and negate the prodiamine leaving me no protection. But maybe if the soil heats up fast to 55 degrees the prodiamine I just put in will kill some of the seeds.......I completely forgot and didn't know I needed a scale as the prodiamine doesn't come wiht a measurement tool
Yeah it's definitely super cold down there. No growth at my grandma's lawn in Naples!
Awesome Vid, thanks my friend :)
I like your methods of testing temperature! Makes me thirsty 😎🍻
You know Allyn after I twist the nut I usually put the shaft in the shower stream to test its accuracy!
smart!
Please make a video on how to identify what kind of grass a lawn is. I bought my place last year and have no idea what my grass is
You’re killing me, Allyn. By me, I mean my subwoofer when I watch your videos in my family room. Can you cut out more of the low frequencies of your videos when you are outside with wind?
Hi LCN, We are a lavender farn in North Arkansas. Last year Crabgrass and other weeds almost killed us. Pro65 will kill 90% of these weeds. However, we are working with other factors a residential lawn owner doesn't have. Our lavender is planted in rows on raised beds with a Sunbelt weed fabric and a 2-3" layer of limestone gravel. From what I understand there is no issue using Pro65 around our lavender. My question is concerning time. We absolutely wont have time to weed this year. So should we apply at .183/1000ft @ 3 months or 2 months? I wasnt sure if we could get away with more chemical longer since we arent working with a lawn, and our season goes past Labor day. (Any weeds will be visible popping up through the gravel) Thank you for time and experience. Lagrange Lavender.
you are probably going to want to get a product locally that is labeled for use on farms. That said, yes you can put down a higher application rate to get longer coverage. This pre-emergent has a yearly maximum and you can apply that max rate in one run early in spring.
I put the temperature gauge in my pants and it shot up to 200 degrees. That was a good tip thanks
Because something is good for St. Augustine does not mean it's good for Floratam (st. aug variant). Put down Spectricide with diathopr on my entire floratam lawn, the blades are thinning. Read the labels as small as the text may be.
I am in south Florida I have Broad leaf weeds long deep roots, wild grass that runs it have seeds like nut edge grass. How can I get rid of them.
Great episode! Loved to big box comps
I started some Zoysia last season with plugs, they did very nice for the 1st year. My lawn is mostly Bermuda and would like to know what would be the best to keep the muda out of my zoysia for this coming year? Thank you
May I ask what time of day to take temperature ?
Killing me bro... -30 on Wednesday this week.
Great info as usual - love your vids! I always have to check label for herbicides for pets. I have 2 small dogs and let them out in the yard. So.... PPE for me and "read the label" as you always say for... everything else, like pets, etc.
Although your way is way more fun I calibrate mine by letting it sit inside my house and match what my thermostat says.
Can I just use a meat thermometer?
I live in Jacksonville Fl. I have been in for 6 months I have baha'I grass they had a tree up front I had it dug up and I fill they space in with st Augustin and it spreading what type of fall fertilizer should I use one for St Augustin or bahai
I think length of days has something to do with it. I'm In central Florida we start loosing leaves in mid August, when it's still brutally hot.
Will this work for Carolina Geranium?
I live in SW Michigan, my lawn renovation germinated on JULY 19, 2021
will i be able to use Prodiamine for the first time this fall when ground temos hit 70 degrees? (I dont know how much time must pass to be safe.)??
5% ABV Beer doesn’t freeze until 26° FI 🤔
so close I was! but hey, as long as we're close right? 😂😂😂😂
Close enough 👍🏻
@@Thelawncarenut the funny thing is that it was closer to real temp before you adjusted it. You made it less accurate :) Thats a plot twist right there.
I tested my digital thermometer the other day when Ginga was asking about soil temps. I tested in iced water and boiling water measure 211 for boiling water and 37 degrees for iced water inside at 70 degrees and 33 degrees outside 40 degrees... the ambinate around you is going to effect your soil temperature measurements
Glass of ice water is always 32 degrees, as long as it’s mixed and there still ice in it.
Water boils at 212F. Just boil water in a few minutes and save the beer.
I live near Nashville TN. Is there a book or calendar you could recommend that would provide a schedule of what to use when?
Name of reggae band diving to Lowes please? I gotta mow to this!
I just installed zoysia a week ago(mid September) Dallas,Texas. Is it advisable to use fertilizer at this point together with pre emergent. The sod supplier advised me not to use any synthetic fertilizers I'm confused because I see my zoysia struggling in some parts of the yard. Please help..
Does this Pre-Emergent cover more then crabgrass? I don't have any issues with crabgrass in my lawn but I do have issues with clover and dandelions.
Hey Allyn seen on the diy channel that if you take high temperature and low temperature for a day add them together then divide by 2 for three individual days then add together the three numbers you got from the individual days then divide by 3 that would be your soil temperature just curious if that would be accurate
Where can I find pre emergent and fungicide that will ship to Alaska.
I'll get that pre-emergent down as soon as that 3' of snow clears... 😂👍
soon then! lol
@@Thelawncarenut Funny guy! 😂👍
Been waiting for a revised video on prodiamine wdg cause people online don't really have a consensus on app rate longevity of protection
I have the truth, straight from the label, and I'm not afraid to share it!
I just put down my prodiamine app from the bag i purchased off your site. I also put down an app of Milo. Im up here in Chicago and my question to you is, do those two apps have any effect on when I can start spot spraying some dandelions that I already see popping up?
First, faster than Conner!
Can you do prodiamine in late winter in South Carolina on St Augustine grass?
so, let me get this straight. You can either do pre-emergent with it in your fertilizer or you can do pre-emergent by itself like incase your using milorganite which does not have pre-emergent in it?
Do you know a date when your pre-m will come out? Both options on domyown are sold out now. I want to be sure I’ll be able to get some in time to put it down here in north central Texas.
Lcn will you ever test out some of those potting soil testing thermometers for ph and such. Just curious if they work at all. I know there's no replacement for a proper soil test.
At 7:00 wouldn’t the math be 3.44 x .29 not 3.44 x .19? Not being a critic just trying to understand the math. Thanks for all you do!
I see what you did to pass the time while you were waiting for that beer to freeze 🙃
I am doing a split application of prodiamine 65 wdg, 1st one at 55 deg. soil temp and then i put down Lesco fert. 24.0.8 2%fe. my question is how long after i put down the Lesco can i do my second app. of prodiamine 65 wdg? should i wait?
I purchased the prodiamine from you recently and applied. How long until i can allow my dogs into the lawn?
I may go by Lowe's and do my own snooping, specifically the amounts of active ingredient in the store brands. The Sta-green product with dithiapyr was interesting, but if I have to double the strength it may not be the deal it seems on the surface. I've used the Lesco 0-0-7 for years but want to switch things up this year.
dithiopyr in general costs more than prodiamine from what I have found, but dithiopyr has a much more lenient yearly max. Both have the same mode of action so are interchangeable that way.
Hello, greetings, I would like to know when is the first date of the year to put prodiamine, between February and March or right now? I would like your help.
download the Yard Mastery app for free - it will tell you when to apply. You can get it in both app stores. Search "Yard Mastery"
Thanks for shopping Publix.
it's my favorite.
@@Thelawncarenut After the last video I would have thought you'd throw Winn Dixie a bone.
Have you ever heard of Fertilome? I would love to hear your insight. My guess if you like Scott’s Southern Lawn S you may have something good to say about Fertilome. A friend as been recommending it all last year and I’m thinking of doing it this year.
if it works for you and it's within your budget then it's a good fert to use for sure
Hey, if you guys have smaller lawns and need less then 5lbs of prodiamine, there are 8oz packs available on ebay.
I've got just over 1000sqft and would of never been able to use 5lbs with prodiamine within its 2yr expiration.
What about timing of a fall application for poa in Michigan? Thx
can you share a cool season info graphic? Thanks!
