DIY how to kill crabgrass. My crabgrass is not dying. How to prevent and control crabgrass

[Music] thanks for tuning in this is Peston longe engine today we're gonna go over crabgrass control believe it or not a lot of you guys think you have crabgrass which probably dope let's check it out so I was really fortunate to find this lawn this lawn has a little bit everything in it you can see right here we've got some less desirable grasses too right next to each other traveling through the lawn got more or less desirable grasses and it just keeps going again the base of the salon is a Kentucky bluegrass but they've got these wide leaf grasses now most everybody is going to call and suggest that we get rid of their crabgrass but interesting enough a lot of this is crabgrass and a lot of it is not crabgrass it's a big difference between controlling annual grasses and trying to control perennial grasses so as a general rule of thumb there's a couple of things you guys need to understand number one there's three different types of grass and weeds you've got your annuals your biennials and your perennials now the reason why it's important to understand the difference between these three is your annuals are the grasses and the weeds that could be controlled you can also control biennial weeds now your perennial grass is important to understand it's grassy you want the grass that you want to live all year round it has a season of dormancy but not death where your annuals and your biennials will grow through the growing stage and then they will either die or they will suck down and go dormant until the next season one of my most infamous grasses that we get to hear about all the time this bunching grass right here the name of this grass is actually not crabgrass it's called tall fescue now it looks very similar to crabgrass but there's a couple of differences if we get really close and on top of this grass you'll start to see the veins of this grass now this these grass veins are really course it's always gonna have a flat square top to it and it bunches and when you get into the root base it's got about a 6 to 8 inch root to it so you have to dig deep and these roots can go really really far but one big tell sign is this node right here that you're dealing with tall fescue you'll notice this node has a cupping shape around the stalk it does not go all the way around it stops halfway through and that's how you tell it's a tall fescue now tall fescue per the name and keep in mind there's about 50 different varieties so don't want you guys getting your panties in a bunch tall fescue versus crabgrass is broadleaf tall fescue that's a bunching tall fescue grows tall grows vertical it does not grow parallel to the ground now coming up on this section we have another species this one is called Johnson grass this grass is not as veiny as your tall fescue so getting in on it you'll notice that it's not quite the same and it grows really really tall when we grab the base you'll notice that the Leafs are a little bit flatter and they don't have that cupping node at the bottom they just have a straight Bunch at the bottom and it grows out almost like a flower so here we're we have an annual grass called quack grass you can tell quack grass because it has these little nodes surrounding it they go into almost a cupping shape around it around the base and it grows from the stalk all the way up again this is another one of those grasses that is not treated and it is a perennial now as a homeowner the easiest way that you're gonna be able to spot an annual biennial or perennial grass is that your perennial grasses will grow and overwinter where your annual and biennial grasses don't so if you were seeing less desirable grasses between the months of November and May or April the end of April you know you're gonna have to dig those out there's no chemical control for those grasses and that's gonna be the best way to do it besides hitting it with Roundup now hitting it with Roundup it's not bad but I do like to stray away from it as much as possible so it's best to be dig them out and just replace the soil now both of these grasses are invasive unfortunately both of them are also perennial grasses that have to be dug out or you have to use a technique called sponging sponging is pretty simple you're gonna get yourself a bucket of Roundup and some surfactants and that's gonna help it stick to the Leafs you're gonna very gently grab a q-tip or some sponges and you're gonna lace the top two to three inches of the grass blade now hopefully over the course of about ten days that roundup is gonna go up underneath and it's gonna travel down you're not gonna have a lot of overkill now there are a couple of things that I gotta warn you with most people put it on too thick you're gonna end up having the ring of death and then you're gonna have to replace everything because the glyphosate does kill everything surrounding it Johnson grass orchard grass and tall fescue are less desirable grasses they grow through our lawns out in our region now since we can't control those a lot of people give up hope and they think that they can't control crabgrass well my friends here is mister crabgrass there's a couple of things that I want you to be aware of and want you to understand this little Spade at the very top is a really good indication you have crabgrass now crabgrass and I really like this right here because you're gonna see it actually grows parallel to the ground off of a stem almost like a stone but it also bunches in the middle and it's really not that hard to control but once it gets to be this big it makes a little bit more difficult but you can see it grows parallel to the ground not tall and that's your biggest tell sign with grass when we get in on the Leafs the leaves are silky smooth and that's also another sign you have crabgrass herbicides could be a great way to control crabgrass now it takes the right spray and we'll get into that in a little bit I kind of want to set your expectations now when you spray for crabgrass this isn't gonna happen like the roundup commercials so want to make it look like it's not gonna disintegrate it's not going to disappear what's gonna happen is you can see here as I'm walking and showing you guys that the crabgrass is going to start turning different colors it's gonna go from yellow to brown and then finally to purple now once we reach that purple state that means it's in the root ball and it will actually die now it doesn't mean it's going to disintegrate and disappear you're still gonna have to do your own hard work and actually dig it out now if I were to guess this crab rest would have been treated a couple of weeks ago and as you can see it's kind of turning all different colors of the rainbow once it starts reaching this purple color you can trace it back and you can see it starts getting purple all the way down to the stem now that's a good sign that your herbicides were effective and they're actually doing what they're supposed to do and that's controlling and killing crabgrass another effective control method for crabgrass is weather once the temperature reaches below freezing outside crabgrass will naturally die so if you're in the late fall there's really no need to treat for it if you're within two three weeks to the first freeze there's also really no need to spend the extra money controlling crabgrass is not too difficult your number one defense against crabgrass is getting a pre-emergent down before the ground temperatures are below 55 degrees you're gonna want to go to Bed Bath & Beyond or some sort of bargain shopper kitchen area and buy yourself a meat thermometer and measure those temperatures after using barricade or / diamine as the generic case you can put that down over the winter to help give you best control and then again early early spring now proved I mean unlike dive out of here does not break down until it gets hot that's when the microbes come out and eat it and get rid of it and redistribute it curative measures for crabgrass are actually pretty simple you're gonna need yourself some Quinn claw rack and some methylated seed oil now the methylated seed oil is the key because if you don't have it you're not going to kill the crabgrass it doesn't stick to the plant well enough and trust me when I say this a lot of people new in the industry forget that methylated seed oil it doesn't work now these two combined will save you a little bit of money now you can there are some products out there like q4 by PB I Gordon work really really well I just find that they take three to five weeks to kill the plant instead of two to three weeks so if you want to save yourself some time putting the active ingredients together yourself will do a much better job in my opinion I want to go the extra mile of controlling crabgrass my my opinion on this is to add some pre-emergent to your tank while you're spraying the crabgrass that way if it's dropped seeds it will help make it so those seeds don't germinate in the future now if your midseason or beginning of the season you're already getting crab grass seed heads that are coming out which is not super common but does happen it's going to stop those from growing and so I want to show you a little bit of a trick here if you have crabgrass like this little piece right here that is still within the three leaf stage you can still use a pre-emergent called death I appear to act as a post emerging and pre emerging herbicide all in one so if you catch your crabgrass early you do not need to purchase the Quinn cleric and the methylated seed oil to do the job you can simply just use the death I appear which is your pre-emergent to get proper control alright guys just remember if you guys want to control annual and biennial grasses with perennial properties you're going to need to identify them properly first you keep treating perennial grasses with an annual chemical it's not gonna work you guys have any questions or concerns hit me up in the comments don't forget to subscribe on your way out and like the video if you actually like it guys I really appreciate you guys sharing my videos I think it's going well keep the good content up till next time guys pestle on digit I'm out
