Quick question I have just used tenacity for the first time n I was wondering if I need to water after I use it n how long before I see results cause tbh it seems like my weeds grew alot more lol. I live in deep south Texas if that's helpful.
Please help lol
I've been very disappointed with Tenacity on my clover, but very impressed with its ability to control crabgrass.
Ryan - I look forward to these videos every week. Just did my dethatching, aerating, and overseeding this weekend! I am thankful for all of your knowledge you're passing on to all of us!
One of the most informative and simplistic videos on herbicides. I’m a user of Speed Zone and it is a very affective product for my needs.
Ron, Does speed zone completely wipe out the weeds then or do you need to apply again? I was going to buy some and try it out
Ryan low key just called his neighbors out.
Great Vid Ryan! Lots of useful info in this vid! Just a suggestion, I think you should have touched on when it is safe to spray a Post like Speedzone after and over seed! Label is the law of course. But some may have just over seeded a couple weeks ago and then go out and spray a 3way Ester! That may setback the baby grass a bit or even kill it. I would recommend not spraying any weed control on a over seed or reno until at least 2 mows on the baby grass. As always I appreciate all your content, and your continued education and teaching! Peace and God's Love! Chad Upstate NY
I totally agree with you on Tenacity. I was under the impression that it's the Holy Grail of Post-Emergents. However, my experience of it wasn't that great. It works though but it was just ok.
I find tenacity works well on nutsedge. Definitely needs multiple applications but I load it with Tzone for more effective results and greater weed selection/coverage. I use Scott’s W&F for my broadcast pre-emergent. Start in the winter with broadcast on the snow around Feb/March. Knocks out most weeds and I do a light maintenance with it at each summer holiday. Keeps me weed free all summer long.
Thanks for the video and great info as always.
Me too, yellow nutsedge in my cool season lawn was basically dead with one application, then I overseeded and did one more blanket application of Tenacity and the nutsedge was totally toast after that. Hopefully there is less next summer, but I know I have a tool to deal with it effectively. They say you should always expect to apply Tenacity 2-3 times to get a thorough kill and not develop pesticide resistance
That was a great video Ryan. I'm currently studying RHS level 2 in the UK, and you gave me a great overview with some excellent practical advice. Can't wait to get started on my lawn. Many thanks.
Great advice on Tenacity. I see it pushed often as an end. Great for seeding, but in my case I follow it up with prodiamine 6 - 8 weeks later based on my germination and seedling growth.
The Bonide weed beater is an absolute beast on weeds. I had a huge clover problem (Tacoma Wa) and the Bonide just obliterated the weeds. An absolute gem
Thanks for this video and all the products reviews, I was about to order Tenacity, I think I'll hold off, your'e the go to youtuber when it come to lawns! lots of great info on all your videos.
I appreciate you watching!
Once you use Speedzone it's hard to go back to anything else, unless you need crabgrass control, then the quinclorac addition is needed.
Q4 is great for that.
People swear by Tenacity for knocking back clover. However in my experience it very slowly kills only about 20% of the patch, which takes up to 3 weeks. By week 4 or 5 it starts to fill back in that 20% it knocked back and I'm at square 1. In general I have much better luck with more broad based weed killers (that also kill clover) and they tend to work faster.
Looking good! Can't wait to really start getting into this community, this channel has been such an awesome source of info for a noobie
So awesome how just maintaining and proper lawn care will take care of most weed problems with very minimal spray if any! My lawn 2 years ago was all crabgrass and now so thick most weeds don't stand a chance! Great videos keep up the good work!!
I know this video is 2 years old but I learned something today. You can mix Quinclorac with Speedzone! I can't hardly wait to try that combo. Thanks Ryan!
Thanks Ryan - looking at your strategy getting away from broadcast weed control. Speed zone it is!
I would love it if you made a video on how to get rid of Bermuda and/ or effectively manage it in a cool season lawn.
Tzone is the best thing I've ever used on creeping charlie. Tenacity is fantastic for crab grass...pricey, but worth it. Two applications with surfactant a must. I use the Ortho on clover and broadleaf. Ryan always recommends good products. Great, informative videos.
Nutsedge is the bane of my yard.
MrMadeinthe80s , tenacity with duo stick surfactant.
Sedgehammer has worked well for me
@@ryanknorrlawncare So far Ive used Sedgehammer+, Certainty, Vexis and Image. I'll kill it off in one area and it pops up in another. Just going to stay on top of it with Certainty until it doesnt come back again. Im not picking it either and the products seem to be yellowing them up and killing it off, but man is it a pain because it grows so much faster than the grass.
Great timing, Ryan! My fall lawn reno grass is grown in. Now I have to spray the weeds that came in too.
Just make sure your new lawn is mature enough and check the labels of the product you are using to see how long it's recommended to wait to spray after seeding
Thanks Ryan. Learned a lot from you. Unfortunately I have 2 Acres with no irrigation and have to scale everything up from what you do. Keep up the good work on the videos
Great video. Thanks!
I just picked up a sprayer today. Used Ortho nutsedge killer with hose applicator last week, it was all over the backyard. The nutsedge is dying off, but some areas have taken a little damage and started turning brown. It's suppose to kill clover too, but doesn't seem affected. I'll wait another week and maybe spot treat it with their purple label weed killer. I'll only spot treat weeds in the front yard to avoid such a situation. Apparently the nutsedge killer is also taking out some crabgrass that was hiding. I have spot treated crabgrass if i find them, usually they are pretty large before i do. I think I put down my pre-emergent too early and not strong enough. Going to do it based on temp next year.
I've been using speedzone for 17 years. Had weed issues at my first house. Went to the nursery and found an old guy in the agricultural area. He turned me on to it.
I assume it is safe for all grass?
@@mkarias11 I know it’s safe for all cool season grasses.
i over seeded 3 weeks ago and part of my lawn is close to 5", will it do any damage waiting for the rest of lawn to catch up making the high half crazy high??? (not crazy crazy but you get it) thanks for great content.
I'm in the same boat as you. However with colder temperatures the growth is slowing. I plan on let it go until the new seedlings branch off with 3 shoots. Maybe only 2 shoots it gets real long. Then it's time to mow, on the highest setting, and bag the clippings. Then a few days later mow again on the highest setting, then a few days later lower the setting a notch and mow again.
I wanna wait maybe to week 5 since seeding to mow but man its moving slowly
I would start to mow it
Thanks mate for the info good stuff this!
I have a good healthy thick lawn, I get a little crab grass when it get hot but in general no weeds.
Can you use speed zone for weeds if I over seeded 3 weeks ago? I'm in Wisconsin if that matters. Thanks!
Another great video Ryan .... thanks for the information and product reviews ..... btw, your lawn looks dynamite!!
Hey Ryan great timing for us as usual and love your videos, thank you for helping! Question: I’m just north of Seattle and I didn’t use a starter fertilizer on my 1,000 ft PRG overseed a couple days ago, can I spray one of the liquids from Simple Lawn Solutions? I have the growth booster on hand but that’s it. THANKS!!!
Yes you can
Ryan Knorr Lawn Care AWESOME that’s the best news ever! Thanks a million
So I notice the directions on the bottle of simple lawn solutions doesn’t say to water in the Growth Booster after application. Am I missing something or is that the case?
You should make some videos about landscaping design. I'd bet that would be a good way to have videos to make over the winter season.
Great content. I thought Tenacity was the end all be all. Appreciate the info. Trying to get rid of a huge patch of creeping bent grass. This weekend will be my second application out of 3. Hope I can eradicate it so my overseed can bring it back to life.
Tenacity is the go to for bent removal but bent is not a weed....well, not technically haha
Really good info. Thanks, Ryan.
Hi Ryan, i hope this comment finds you. I love you videos. Your videos make me feel like i can tackle my own lawn problems. Is there any way i could send you pictures of my lawn and get your advice? Also im a little worried about using chems on my lawn where the kids and the dogs play. Hope to hear from you.
Hey! Unfortunately I can't do one on one due to lack of time but I have many resources here in the videos and guides on my website as well
Great information and tips Ryan! 👍🏻
I'm new to lawn care, so I am delighted to have found your channel. I live in SE MN. Just sprayed my whole yard with Tzone, (it needed it.) I will hit it with fertilizer in the next couple of days. I would like to do the liquid aeration this spring, and also a pre-emergent crabgrass preventer. Should I then wait until late August to overseed, or can I/should, I overseed before the crab grass preventer?
Thanks to your channel I have a much better looking lawns during the fall-spring monthes. The one spot I still have issues is around my rosemary bush. Does rosemary kill or stress turf, or do I have another issues that I still need to investigate? I'm doing the same thing to that part of the lawn that I'm doing to the rest of the lawn., and the rest is flourishing.
Dang man! You rounded the bend to 200k subs! Almost there!
Tenacity needs to be sprayed 2-3 times for full effect. Best to spray bent in the fall with Tenacity. It will wipe it out!!!
My yard was about 50% bent. I've hit it twice within the past 30 days and seeded 2 weeks ago. Might spot spray it one more time in a few weeks. Seems to be dying off good.
I used 2/3 teaspoon per gallon, rather than the 1/2 teaspoon for broadcast spraying. The 1/2 teaspoon is for spot spraying weeds because people have a tendency to over do it when spraying weeds. Use a non-ionic surfactant like turbo sticker or just plain old Dawn dish detergent. It breaks up the wax coating on the grass blade and allows the Tenacity to get in easier. Good luck to you!!!
This is very helpful. thank you.
Great tips and another great video!
Hi buddy I live in Oklahoma with some clay based soil. I'm trying to get my annual Ryegrass to bust off any pointers.
We have not had any rain in a while but we have great well water.
I aerated the group and even drug a pallet with nails in it 2 weeks ago but still hardly any growth. Love your videos and thanks for your help. If it helps I can link a video of my lawn if that helps.
Thanks
Shea!
Can youu do something on poa annua. Its a nightmare for me
I wish i could just hire you to come over and fix my terrible yard and make it look like yours haha.
I didnt know you have a lawn care channel. Great music btw, could you do some vids playing your songs on your guitar?
Man great video truly helped me out!!!
I just did a complete lawn renovation on a new construction. I’m seeing dozens of ant hills as the baby grass is just sprouting. Is this an issue? I don’t want to spray and hurt new grass. Maybe a video on this would help those who have complications on a yard renovation! Thanks.
Sure wish you where my neighbor....lots to know great video.
Any recommendations for moss?
Great video Ryan. I just did a complete renovation and the soil sand combo I got must have had goose grass seeds in it. I didn't blanket spray tenacity before I seeded because the starter fertilizer had it in there but still came up in my SS1000 tall fescue. Mowed it 5 times now question is what would you spray. Thanks and keep up the awesome videos.
The Man with the Plan Ryan Knorr gettn it done!😎👊 Awesome!
My lawn is perfect no weeds. But I do apply weed control to my elderly neighbors lawn.
So did you hit your newly seeded areas with the drive and speedzone?..i have both products that i use for my spot spraying..i just renovated and noticed crabgrass popping up..i wont concerned and said i will just get it with a pre in the spring..itll be dead n gone in a month anyways..
The areas I sprayed were ones that I didn't do Overseeding
Great information!
I still keep getting confused about how/when to use tenacity, humic acid, super juice.
I overseed my lawn 2 weeks ago. Can I spray the newly seeded areas?
No you will need 3-4 mows before any spraying
Thank you for replying and the advice!
RYAN. you have dogs as I do. What is your suggestion when spraying these products when it comes to our animals.
Thank you, Ryan👍
Does this also apply to new renovations done in the last month? My new grass is a month old and I want to prevent as much weed as possible for coming up, but I am not sure if these products will kill my young grass
Most of these products will mention applications to newly seeded lawns. Usually the new grass is mature enough after 3-4 cuttings to handle herbicides. But as always, the "label is the law".
For a new lawn I would always error on the side of caution and know you can deal with weeds later on
@@ryanknorrlawncare I just read this comment and would like your opinion. I over seeded/core aerated my lawn and the grass is growing but I'm seeing some weed growth, would you recommend I do anything now or wait until spring? I really do appreciate your videos and look forward to watching them. Ps.. I'm seeing mushrooms growing in the yard, should I get my soil tested or is there something I can do? Thanks in advance.
@@andrewfiertek5937 I can’t speak for ryan but I just did an overseed, I’m gonna wait until spring to kill the weeds. The mushrooms, you can just pluck them, bag them and throw them away. They’re harmless to your lawn
@@bertieckid thanks I was thinking about spraying in the Spring and now I will! TY
Hey Ryan, I've got tall fescue.
What do you think of a weed and feed spray that connects to your hose? The one I got is a weed control plus nitrogen. Thanks for all your info. Your grass looks killer!
Have you had good success with the ester based herbicides in cool weather? I’ve heard mixed things..
Ester does well in the cooler temps but if it's super cold, the control might be slower
Tenacity and prodiamine is safe to use at the same time for cool seasons, yes? Spray one, then the next day spray the other (I ask for for early spring pre emergent control) for next year.
I suppose you could do both. I just go with prodiamine or similar in the spring
Ryan, do you have issue with Bermuda grass? If yes, what would you recommend do use?
I would have thought tzone would be more effective than speedzone. Tzone is a 4way herbicide and speedzone is a 3way. I used tzone at max rate on what I think is creeping charlie. It weakened the weed. I reapplied yesterday. Hopefully it will kill it this time around
24d in the strength found in speed zone does a lot of control for many things
Par3 is the best stuff i have used too date
Absolute legend
what to use in Europe? we have almost zero products compared to USA.. and when you find a weedkiller you have to have a license to buy it
When are you going to go all in, and get a bentgrass yard going?
Someday
You have so many products to use against weeds,crabgrass.. Forbidden for homeowners long time ago here in Sweden...:/
I have quite a bit of weeds on my lawn. I’m in the northeast, if I spray weed killer now how long do I need to wait to aerate and seed?
saw some sites recently mentioning putting down pre-emergent in the fall rather than spring. any input?
Which weed killers are okay to use on grass that only has germinated a week or two ago? I am scared of accidentally killing the seedlings, but I want to kill a few weeds popping up. I'm seeing what I think is clover, dandelions, and some kind of wide bladed grassy thing that is a lot lighter than the grass.
Tenacity only on new grass. Wait a few more weeks for anything else
I wouldn't worry too much about the weeds right now in a new renovation. You can start to take care of that when things have matured
@@ryanknorrlawncare Thanks for the advice!
Do u have a video on a good yearly program? I had my yard hydroseeded last summer with fescue and it’s grown in great and thickened up but I’ve got a lot of weeds that came in over the summer especially clover. I put down milorginte in July and Scott’s winterguard weed and feed two weeks ago and after that app my yard looks worse than before. It’s dry and browned a bit maybe cause I went to heavy on the scotts.
Can U blanket spray using the speed zone????Or is it only for spot spray????
Great video I live in Texas and I have Saint Augustine grass is very thick and healthy but it always die in the winter time what can I do to keep it strong and green doing the winter time what do you recommend
That is a warm season plant. It is natural to go dormant or brown in winter so not much you can do there
Can you do a video on the key points to get a thick lawn? My lawn is never thick enough and I think that's because the lawn is very muddy. Although the soil seems wet all the time, the water actually cannot drain properly. So the seeds will float on the water after I overseed. Have you experienced that?
Steph Fong Spraying liquid aeration on the poor drainage area is one thing that could help.
I have potbelly piggies dat are house trained and go outside to potty and stay outside. What do ya recommend fer a weed control dats safe fer piggies
How do I control weeds on my new seeded lawn?
So Speed Zone (and all the other) is safe for all grass?
Hi. Is there a pet's safe fertilizer and variety weed killer but not grass you could recommend? My pupson eats grass for his gut. And I don't want to use chemicals that might damage his health... Great video.
How soon after overseeding can I kill or remaining weeds with these products.
How long should you wait to apply weed treatments after a renovation? I’m 3 weeks out and the tenacity is starting to wear off and little weeds popping up. I haven’t mowed yet and probably a couple weeks from that (KBG). Thank you!
I wouldn't worry too much about the weeds at this point. Once that bluegrass matures you can see what weeds have survived into next season
I did a tall fescue overseed 4 weeks ago and where I overseeded it's looking great, some of those blades are 4 in tall and I've already mowed them twice but some of my bare spots just don't seem to get tall or thicken. I am trying to figure out what is causing those areas not to grow tall and thicken like the rest of the lawn? Any advice would be helpful
So many variables that it's hard to say but a check of the soil there is a good first step to see what might be different than the areas around it
@Jordan Friesen I am in a similar boat but used blend of fescue and KBG. My weak spots I think is caused by lack of water coverage or by the fact that I can't seem to keep the family from walking on the lawn.
@@ryanknorrlawncare Does it make sense to add some top soil and do another seeding in those bare spots or wait to the spring and see if anything fills in?
What would be the best product for clover? Lot of it!
:53 Lawn looks great. You have to be the talk amongst the women of the hood (the guys must hate you though haha)
Can you mix tenaciuty with others,, like in the same jug?
When you say same jug do you mean the sprayer’s compartment?
At best I would use to separate milk jugs to mix then combine. If you really want to be safe you can use smaller containers, and as long as combining the two chemicals afterwards doesn’t turn into a gel solution then you should be safe.
What is the second ingredient? You also want to avoid canceling out the effectiveness of the two chemicals, so if you want to be even safer look up the active ingredients of Tenacity. Then cross reference that with the new herbicide to see if there is already a known product combination at the pro-level.
ZeroTurn just wanting to mix tenacity and tzone some surfactant, so I don’t have to spray twice
Is it ok to use SpeedZone & Drive xlr8 four weeks after seedings?
I need products safe for a dog....what can I do?
My backyard is thin from washout after new construction/Hydroseed. Lots of crabgrass or quack grass after july and onward. Would you recommend not doing a pre-emergent and just overseeding the heck out of the backyard and once that grows a bit, then apply a pre-ermergent?
You could try putting seed down right before winter and hopefully having it come up in the spring and then applying pre-emergent after things have emerged and germinated
Thanks man, I really appreciate it. Thanks for making things so easy to follow along and clear to understand.
Don't pre emergent kill grass seed too? What do you think is more important kill weeds first or level over seed? My dad waited too long to cut the grass and left clumps of clippings that killed half the lawn so I bought a thatch rake and got most of the dead stuff flattened loosened and removed
I would start getting grass growing and take care of weeds later
Weed control with a pesticide ban. what's your recommendation, Ryan ?
Love it
How long to wait with tenacity after an Overseeding? I missed the “do it at seeding” poibt
Do big box stores carry any of this? Menards only carries granular products
Menards will have the weed b gone and similar homeowner options
I have Bermuda and I have a clover problem. I’ve used home owner chemicals and can’t seem to control them they keep coming back every season
For bamboo, I must use glyphosate?
Hello Ryan thank you for sharing your knowledge. After how many days we can start mowing after overseeing with Ryebgrass. I am in zone 5B.
Whenever it's tall enough to mow at the height you want to keep it at so basically 10-14 days is usually when I start
What about getting rid of fungus?
