Great video Allyn! You always remind me of the Dad in ‘Honey I Shrunk The Kids’ laying in your grass with that contraption on your head..lol!

[@wwolfram33]

During the spray application, it is mentioned to spray tip to tip (@12:43). Does this also mean 'edge' to 'edge' of the spray into the yard?

[@webbspinner57]

I still love the crunch of your lawn as you walk... looking forward to when my lawn gets to that health.

[@sandywilson8169]

Glad I watched this, been binging your info lately.. watched several videos about applying Prodimine and most say 5.2g per gallon/1000'.... it appears that here in SE Florida (Ft. Laud) I doubut my soil ever gets below 70 degrees for more than a couple days all year, so the standard application rate for me would be 13g per galon.

[@TheLawnCareNut]

5.2 g / 1000 in early spring and gain in mid-late spring and 13g / 1000 in fall (now)

[@webbspinner57]

Just want to say thank you for all ive learned from you. Before these weeds emerged i was the new kid on the block banging my chest. i'm looking forward to seeing the health of my lawn in the spring. hopefully all this prep and work helps my lawn get healthier.

[@sj7601]

I just calibrated my backpack sprayer today -- never used one before. Honestly I did the lazy way and just filled it up with 4 gallons of water (I wanted it to cover my whole lawn which is only ~5000 sq ft), dialed it in at a lower psi so it's not misting, and then walked at the same pace I do when spreading granules. It worked out pretty well, I was left without any water towards the very end. So I'm going to decrease the psi a bit and pick up my pace. My first application I'll be trying out is hydretain -- if it ever rains up north so I don't have to water. I really needed this for the summer we had, but I'll try it out for the fall.

[@TheLawnCareNut]

Yes that is also a good way to do it for sure! It's pretty funny how if you just go by "feel" you can usually get it right.

[@shakenbake11]

So for TTTF, recommendation is 3 apps, 5.2g, 5.2g, then 13g in fall. If I plan on skipping the fall preM due to overseeding, do I just stick to the same spring 5.2 and 5.2g amounts?

I started watching the part 2 and you answered my question very clear. So, thank you again. 🤘👍🏼

[@nemodown1]

Allyn totally renovated my front yard August 1st. Replaced weedy bahia with Arden 15. Everything is going strong filling in beautiful. I'm in orlando, when can i safely use a preemergent? My lawn probably wont go dormant. I will say the the Arden is stifling the nutsedge which previously ruled my yard. Also thanks for all the great info... Your the man buddy

[@TheLawnCareNut]

Pennant Magnum is what you want if you have nutsedge issues - it's espensive but worth it. You can apply it after the sod is rooted and you have mowed at least twice

[@nemodown1]

[@76tigga]

do you have any problems with the prodiamine granules settling on the bottom of your tank? Also, what is the ramifications if I add too much of the prodiamine per gallon of solution? I would think over-saturating the prodiamine on my yard is not the most environmental friendly thing to do, but it's for the sake of keeping crab grass at bay/

[@irinasharomova2267]

Thank you for reminded about do not put Prodimine if reseeding. Almost forgot about that. Then question. Can I apply Tenacity instead for fall pre emergent?

Lower nc, just put out granular dimension today sep 20. I'm afraid I'm a little late but threw er down anyway. Should look way better than the untreated centapied Lawns in 2 months. Thanks

[@dr.w7426]

Health-wise, what is safer to use: granular or spray (assuming a reasonably cautious person is using either, and not spraying on windy days)? I am thinking about exposure over time.

[@kylegordon9499]

I plan to over seed in 3 weeks, I have alot of crab grass right now. Can I spot treat that crab grass right now and still over seed 3 weeks later? Or should I let the crabgrass just die on its own? When over seeding in the fall, do I just wait for spring for any pre emergence? I'm in Maryland.

[@tylerhartsough9040]

Can I spray prodiamine and tenacity in the same container? I have existing weeds that I need to get rid of as well

Thanks Allyn. Never used pre-emergent before, but waiting for the granular prodiamine to be back in stock on your site for my first application. Maybe next year I'll try the spray. I did spray Sledgehammer a few weeks ago. Finally seeing some results but the kyllinga is still hanging on.

[@ricker752]

Can I add blue die to keep spraying precise?

[@stump182]

Not with that yellow product. It would just make green. :)

[@ricker752]

Lol

[@TheLawnCareNut]

the blue only shows you where you sprayed and if you end up "painting" the entire area but have some left in the tank, then what do you do? It's better to understand the why behind what you are doing and then you'll have the confidence to move forward. It's not as difficult as it looks.

[@thekellercrew]

I just bought two bottles. I have a little over 15000 sq ft. I'm using a tow behind sprayer. My understanding is I add enough water to cover my sq footage as long as I use the min dilution of 1 gal water per 1000 sq ft. Usually its around 18 gallons of water in my sprayer based on my pump pressure and tractor speed.

[@TheLawnCareNut]

yes that is will work, have fun! spray and pray!

[@markcurran4748]

have you done any videos on creeping bent grass?

[@superfigaccione]

I produce a similar sprayer and you are a real good user!

[@tucobenedicto109]

Currently I have a hand pump sprayer, and a large yard front and back I put down a post emeregent killer (granular) in August but in the spring because we are going to seed i will need post emergent weed killer as they have taken over. So I looked at the battery operated sprayers and the royobi is so much cheaper than the milwakee backpack not sure why? I do have some royobi batteries and have been wanting to upgrade to lithium but watiing for a deal. The lawn is in the northeast! I might put the sprayer in the mower cart and drive around. Nice video's.

Hi Allyn, I have a liquid aerator solution that I was going to spray on my St. Aug.

[@glowzinthedark69]

Might be a silly question...but can you apply Pordiamine AND Dithipyr BOTH? I picked up some Dithiopyr WSB and I am only covering ~2500sqf total....and after doing a lot of research and math I am just wondering if I will be covered in case I screwed something up. I live in CO and I primarily have KBG..so based on my math I applied 3.3g of Dithiopyr on my ~650sqf section of front yard...which doesn't seem like a lot...hence my concern. I know the amount doesn't matter...I just want to be sure I am getting the coverage I am looking for. Thanks.

[@Ambrosius13]

I live in Ellenton Florida. Do I have to wait for the soil temperature to get to 55 before I apply? Does soil temperature even get that cold here?

Never mind. Just read that it should be applied in the fall when the soil temps reach about 70. Which here it will be some time in November

Allyn, the smaller bottles of prodiamine are game changing! I just wish those had been around 2 years ago when I pulled the trigger on the 5 pound jug :D Will you be getting them to make other smaller quantity herbicides, etc. for you? Maybe a pint of a PGR like trinexapac-ethyl, etc.? Lots of possibilities there....

[@pevelyhomeowner327]

Symbiont 01 , I bought the 5# jug a couple years ago too. Still a way better value is you have larger yard. 5 oz is less than $5 so your way ahead I’m sure. Those folks with small lawn will really like the 5oz size for sure.

Some of them have a 3-5 years expiration on them, others not. My opinion is that if you keep it sealed and dry it should be fine.
