Great Explanation! I am a LCO in CT and this year is horrendous for weeds/crabgrass. I do 2 apps of Dimension .15 full rate and still had issues. I have used Prodiamine in the past and I am thinking next year doing what you have suggested. Also, you mentioned the battery operated backpack sprayer. I purchased 2 Maruyama battery sprayers about 5 years ago. I use them every day and I have not had an issue with either one. They are nicads, but the new ones are lithium batteries. They are excellent. I can spray for 1-2 days on one battery. I keep a spare in the truck.

I want to thank you and also curse at you. Until this spring I was happy with my lawn. But now I'm obsessed. And also now I have the earthwise chipper I have opposite problem of to much browns for my compost pile. It all started when I tried to identify my quack grass. Why couldn't I get rid of this 6'x6' patch over the years. I sprayed normal spray, used weed n feed, and hand picked it for years. I soon realized I had several bad grasses. Quack, poa Anna, and bunching tall fescue. I have painstakingly hand painted blades of quack all summer. I shoukd have nuked an entire zone. But also I think I'm getting lots of quack grass seed germination. My spring overfeeding didn't go real well because I watered to long and the peat moss and seed washed off some big spots. Just a slight slope. Also a few dry hot days fried some baby KBG. But my labor day seeding is growing in much thicker. I used more heavy top soil and peat. And only 7 min water times. All the fescue was cut out and mew sod has blended in. Im getting compliments on my yard again. Oh also you got me using micro nutrients, milorganite, Humate. My neighbor is now feeling bad he has 60% bunching fescue. I know he is. Plus he has big patches of rye. I know he looks at my 100 %KBG with envy. You may have taken away many fishing trips this summer but my yard is kooking good. How deep do I go down this rabbit hole??

[@pestandlawnginja]

Being the Joneses is not an easy journey but when you see the look of envy on people's face it makes it all worthwhile. Nice job slaying that lawn!

Hello Pest and Lawn Ginja, First and foremost, Thank you for all of your very-informative and extremely helpful videos. As a newbie lawn caretaker, your video have helped me tremendously. I finally learnt about preemergents and am very interested in using the Prodiamine on my grass. I am in Michigan, the temps currently are in the 20s-30s. I have Kentucky Bluegrass. I usually see a lot of Canada thistle, crabgrass and some broadleaf weeds on my yard, some dandelions too now and then. I dethatched my grass last year after watching your videos and fertilized it with Propeat, and it really helped, but the weeds still showed up now and then. I am wondering if this Prodiamine application once the temperature crosses 35, and then a Dithiopyr application in May/June would work for the weed problem I am facing, or do I need to go for something stronger? Thank you.

[@aceign3278]

BEST pre-emergent video ever! TYVM:) One question. How and when do you apply Fall pre-emergent? What is considered late for SC?

If you’re going to do it you’ll want to apply it as the soil temps are starting to get below 70 degrees. You can use a meat thermometer 🌡️ or a temperature meter found on line like green cast

I dontt hink I put mine down in time because boy I got insane weeds, but in all fairness I think it comes from across the street. My neighbors yard is riddled with weeds.

It's all about the soil temps. before 55 degrees in the spring time and before 65 degrees in the fall time. be sure to keep on the proper watering to keep it active. If it heats up or dries out it also goes away.

[@leland5150]

Be fine for mulch and stone. Immediately water it in. You'll run a risk of some temporary staining

[@raji1607]

Hi, need some help! We are probably very late and havent applied a pre or a post emergent. Should we start with a post emergent to kill existing crabgrass and then apply pre emergent? Should we water the lawn a day or two after the post emergent and then do the pre emergent? Ours is bermuda grass. Should we also apply any nitrogen fertilizers? Sorry for all the questions, but I am quite new to lawn care.

[@pestandlawnginja]

Pre -emergents are for pre seed germination. So you would want to apply a pre emergent pre 47ish degrees F ground temp. Post emergents are for when the weed emerges and presents itself to you. Pre emergents need to be watered in and post emergents should stay dry according to the label recommendations. Bermuda grass is a very hungry grass in general. contact your local agricultural department extensions for local recommendations on how many lbs of nitrogen should be applied per season. This number will most likely fall between 4 and 7lbs per season of N.

Can prodiamine or dithiopyr cause root pruning in the spring to either established turf or turf that was seeded in the fall, or does it not get that deep in the soil (at least for the prodiamine)?

both have the potential of causation.

if i did a lawn reno sept. 12 grass looks great now should i wait for the pre emerg. till April? I did use Scotts starter seed with meso. 3 times. lite application yesterday for the 3rd dose. I heard it will take out the new root system even if i do it in April. Also is the Granular version better for slow breakdown if you have heavy rain?

[@pestandlawnginja]

I'm not a huge fan of pre emergents if you can avoid it. If you have a history of weeds Its a preferred method to stop the process of germinating new weeds. it does effect root growth but i wouldn't say i've seen it kill a lawn. the meso apps only last 3 weeks tops as a pre emergent. If you were dilligent on monitoring your ground temps then i would stay that route this season. just be sure to apply it at the right time. crabrass germinates 5 days at 50-55 degrees F soil temps.

[@ERMAC4482]

Just a few question's.. 1)The pre emergent needs to go down two weeks before the ground temp is 55? How do you know its gonna be 55 in two weeks ? 2) How far apart do you fertilize and use pre emergent? 3) How does Pre emergent and fertilizer effect grass seeds ?

Subbed! Doing the lawn myself for the first time this year, and your clear breakdowns are invaluable! I have decently established bluegrass/fescue, but it's never been dethatched. Should I wait until the grass starts actively growing before dethatching and then leave a couple of weeks for recovery before prodiamine/dithiopyr?

[@pestandlawnginja]

You can apply pre m the same day. Bluegrass needs a kickstart of nitrogen at the beginning of the season. I would power rake as the soil temps hit above 50 degrees

[@starlightwolves1525]

When I did landscaping we would cut the water off to the Bermuda grass (summer grass) for about 2 weeks before we thatched (power rake) then we would mow as close to the soil as possible and then overseed. Sometimes we would put manure over the seed to help germination and keep birds from eating all the seed.

I live in Northern California near the Sierra foothills it doesn’t get that cold here between high 30’s and mid 50’s in winter I’m on 5 acres and I want to kill all the grass and weeds that are on the property because the grass though it looks pretty in winter and spring quickly sprouts foxtails. What do you recommend to keep it from coming back year after year. Oh not to mention I also want to get rid of the grass because I live in a high fire danger area too

[@pestandlawnginja]

Great question. I would do 2 apps per year with prodiamine. Right before ground temps get up to 45 early spring and right when the daytime temps get regularly below 80. Between those apps I would consider a treatment or two with dithiopyr assuming the daytime temps are below 85. Most weeds to actively germinate above 85 degrees. Other than that glyphosate (non selective herbicide) will be your friend for killing everything off. You'll need to do a reapplication every two to three months or as the weeds come up. It's important to remember ore emergents disrupt current weed seed germination. If the weed has already germinated over the past 18 months It will still emerge and that's why we call herbicides post emergents.

Personally i like to hand pull the weeds near fruit trees. you run a risk with whatever fruit tree if you spray the roots dead on. more specifically with oil based herbicides like ester based herbicides. I've been doing this a very long time and haven't experienced many issues with trees dying but the risk is there. when it comes to pre emergents i haven't really seen much of an issue.

@@pestandlawnginja You might have helped. Last year I had Japanese Stiltgrass quickly invading several ivy beds and I could not keep ahead of it here in the Virginia Blue Ridge. Cannot find the ideal amount of Snapshot granules to apply for, say, a thousand square feet of ivy beds. 3.45 lbs? More or less? 1 lb=3 cups, apparently.

[@pestandlawnginja]

Hard to say because it's a perennial plant. Your best bet is to use roundup, triclopyr ester, methylated seed oil and snapshot. Keep in mind the roundup needs to be a non repellent glyphosate based and will kill everything it touches

[@jlcsr09]

Pretty much only concerned with grassburs, anything else doesnt bother me. What’s your recommendation on that?

[@pestandlawnginja]

Best solution I've found is 2 apps of prodiamine early spring and as soon as the daytime temps get below 80 at the end of the summer. I'd personally spray the area every 6 to 8 weeks with glyphosate and a touch of nitrogen.

[@KKing-rf4ix]

@@pestandlawnginja Assuming the spurs are in turf grass like mine are, won't the glysophate kill the grass as well? I have a Bermuda/St Augustine blend here in Central Texas and have been fighting these "Devilheads" for 2 years... any other suggestions??

[@pestandlawnginja]

your assumptions are right. do not use glyphosate on grass. I'm sorry I didn't understand that's where you were applying it. You'll need a good 3 way herbicide rated for bermuda / st augustine. I would do 2 to 3 applications of pre emergents throughout the season and skip the hot months. The heat breaks down the pre emergents.

[@pestandlawnginja]

I would apply the herbicides monthly throughout the entire season, this season and next.

[@pestandlawnginja]

I've touched on that a few times. the issue is this, it all depends on the ground temps being lower than 50 degrees for a proper application. if you put it down anytime after you run the risk of the weed seeds having already started or completed the germination process. get a digital meat thermometer from walmart and be sure to get your pre emergent down before it hits 50 degrees.

Would summer be the proper season to put down post emergents such as ortho and round up? or is it best to perform this action in the fall season.

ortho and roundup have a lot of different products. what they're most infamous for is their production of roundup which is a non-selective herbicide that kills all living plants it touches. Its best used when the daytime temps are below 80 degrees

Thanks for the info and links. I am considering buying the items but I'm pretty sure i'm too late to apply them this year. Had stickers real bad last year. I live in Kansas. Subbed!

[@pestandlawnginja]

Hey Ben! Thanks for the sub. Stickers can take about 18 months to get rid of if they're a biennial like the ones I delt with. If your soil temps are above 55 degrees I would consider blanket herbicide apps every 4 to 6 weeks to ensure they dont get to seed. Then focus on the fall pre emergent.

[@Troy-Echo]

Temperatures? Everybody knows by now that knows anything about Pre-Emergent herbicides that you want to have them down well before the soil temps reach 55 degrees, but I never hear anybody mention anything about soil temperatures for the fall pre-emergence herbicide applications? The Pre-emergence herbicides you put down in the fall - do they stop weeds from germinating and showing green weeds in my Zoysia lawn over the winter, or just set you up for the following spring weeds?

[@pestandlawnginja]

Great question. it will disallow any seeds from germination once applied correctly. it will prevent fall germination which disallows some annual fall weeds and some spring weeds as well.

[@Troy-Echo]

@@pestandlawnginja At what soil temps do you start applying Pre-Em in the fall? I'd figure this is a bit more touchy as the warmer soil means more active microbes to eat away at the pre-emergents?

[@pestandlawnginja]

It's all about the ground temperature. If its post 55 degrees you'll only get post emergent control of crabgrass up to the 3 leaf stage, you will get limited pre emergent control since most seeds complete the germination between 50 and 60 degrees.

[@timothye8647]

Any recommendations for a new lawn that was hydroseeded last May (out of my control on the timing as it was a new house we bought) and didn't take well? I need to make it thicker but at the same time it was 30-40% crabgrass by mid summer last year. Not sure if I should try to control the weeds first with a pre-emergent or try to fill in the patches with new seeds and fertilizer? Or is there a way to do both and I'm missing it?

[@pestandlawnginja]

tough situation. in an ideal world we would have hoped they would have prepped the soil first. All things considered you may want to look into using Tenacity for its pre and post emergent properties assuming you're planting a cool season grass. I would do a post emerging herbicide to treat first with the tenacity before planting the new seed. I would do 2 tenacity treatments then a 3rd while planting the new seed. I'd hit it every 3 weeks as mentioned above.

[@timothye8647]

Sounds like the only way I can grow new grass and control crabgrass is with Tenacity. Yes I'm in Ohio so cool weather grass is the choice. It's a KY blue/fescue mix which is part of the reason it didn't take well last May/June with the lack of rain and high temps. We didn't move in until a month after they hydroseeded so nobody was around to take care of it.

[@badbradno2005]

Would either work on poa annua? Can't get rid of it.

[@pestandlawnginja]

both work well for poa. The prodiamine will do a better job. My recommendation is to do a late fall app and an early spring app with the prodiamine. tenacity will do the job as a post emergent solution to poa annua. Make for certain you are dealing with poa annua before purchasing the post emergent, it's not cheap.

[@pestandlawnginja]

The september and march services make sense. I personally wouldn't put it down in June. Weed seeds aren't commonly germinating in the heat of the summer IMO. The microbes are also feeding fast and the pre emergent won't last very long in those temps.

Hello, I’m in a sandy area in Minnesota. Ive brought in topsoil, and while Im getting the lawn established. Herbicide in late spring and seed in the fall. I have some open real estate for weeds. Not a big deal, Except for the sand burs Ive been pulling by hand. Do either of these work for sand burs? If so how often do you treat the lawn to prevent? And how much time do you need before you can lay seed again?

[@pestandlawnginja]

both of these products will help to disrupt weed seed germination. Sand burs are difficult because of the timing of which they germinate. If you were diligent in the application throughout the season I would say you'll do better than you're doing now. It may not be a saving grace for the first season. I commonly set peoples expectations to 2 seasons. The products do not kill weed seeds. Sand bur weed seeds can stay suppressed for years before they germinate. Regular post emergent herbicides and pre emergents will lead you in the right direction.
