Spectracide Weed Stop For Lawns Plus Crabgrass Killer Concentrate

I buy this to fill up the sprayer from the same brand that goes to a hose. It does the mixing for you so you just pour it in there and go. I buy this to refill it since it is cheaper for the refill if you already have a sprayer. Or you can mix it with water and use it with a bug sprayer. You have to pull back the label to see the full directions. I have found that it works best if the lawn doesn't get rained on for a few days. Waiting for a dry day will make it have more bang for your buck. Also, it can really take out weeds but it takes several days before you will notice a big difference. I use it whenever I see weeds. Roughly about 4 times per year. My yard has got a lot better since I have been using this for about a decade. You want to put seed down a couple weeks before or after using this. Not at the same time. If you use it when it is too hot it can sort of burn the grass but it hasn't been an extreme problem. It won't kill the grass if you use it as directed. Some weeds it doesn't kill or takes more applications. When you apply it you don't have to do very much. Just spray it on there and wait a week. Then do it again. Putting too much on at once seems to make it not work as good. It also works better if you aerate right before you put it down so that it gets to the roots. Several applications is better than a lot at once. It is a good deal for the price. It works best when used right after cutting the grass.

This stuff really works and my yard looks great. It really does kill the crab grass and all the other weeds. The spray bottle is easy to use and has a good coverage. It connects easily to the garden hose.

"Spectracide Weed Stop For Lawns Plus Crabgrass Killer Concentrate" was recommended by a local lawn guy as the easiest consumer product to use to clear out weeds and crabgrass. Professionals have access and expertise to use other products which work faster or are labeled for other uses now, but are still highly effective. $10 is a bargain compared to the $65-$200 stuff they use. Plus, for my yard, I can't justify the higher cost even if it is much cheaper to use, since the chemicals will need to last 10 yrs in those higher cost containers and don't deal with as many different types of weeds as Spectracide Weed Stop does. Waited until the daily temperatures were below 85 degF for a few days in late August. Never spray this stuff when it is too hot or you will kill the grass too. Ask me how I know? The weeds were taking over my Bermuda grass lawn because the Bermuda isn't as thick as it could be. Weeds filled every bare and slightly open spot that was available. I'd used some vinegar+dishsoap+salt for spot treatments of crabgrass which was very effective, but it kills everything, so for a yard with 50/50 grass and weeds, it isn't practical. Put the amount of product amount, unmixed, for my 3000 sqft grassy area into the Ortho 20gal hose-end sprayer, set the rate for whatever the instructions said and sprayed the entire yard during a dew-less morning. No rain expected for a few days. By late afternoon, some of the weeds were already showing signs they were dying. Many weeds didn't show any signs of issues for a week. I'd planned to spray again 14 days after the original treatment, if needed. By the 10th day, the vast majority of the weeds in the yard were clearly dead and the Bermuda was looking fine. I didn't spray again. In early Sept, put down some 0-0-7 fall pre-emergence. Will need to do that again in December and March. Yes, there are better products for specific weed types. Yes, there are homemade ways to deal with small patches of weeds, but I don't know of any easier product that provides the same value for weed control of larger areas with mixed grass and weeds. The 32oz container is only half used (actually, I think 20oz was used), so there's enough for treatment next late-May/early-June, if my pre-emergence efforts aren't perfect or I can't get the bermuda to fill in again next spring (which I failed to accomplish this spring too). I applied at the lower end of the application rates suggested and fully expected to need a 2nd treatment, but didn't need it. Of course, not every weed is gone. Late in the season, getting bermuda to fill in where my soil is a little acidic and mostly clay is hard. Other lawn care is necessary for the bermuda to fill in better. The yard is in Northern ATL metro area, so the timing based on temperature requirements for effective use really matter. Mid-June it is already too hot for use. I was surprised that we had cool, dry, weather in August for about a week. About 5 yrs ago, I made the mistake of applying a similar product without reading the temperature requirements carefully. This was what killed half my grass and has lead to the struggles to get the yard back since that time. I'd used that other product for a few years successfully - probably was just blind luck. It was very effective. Read the labels. Watch some youtube advice from grass people IN YOUR AREA. Ignore the advice from people in different parts of the country. They don't know what they don't know. For me, that means advice needs to come from Northern Alabama and Northern Georgia grass people. 50 miles south and the climate is different. 50 miles north and the climate is different (plus there are mountains). Advice from guys in Indianan, Iowa, Chicago, Texas, California, or Phoenix are probably great for those areas, just not good advice for a guy like me. Perhaps your local AM radio news station has a Garden Guy on the air Saturday mornings. Good source for local knowledge and questions too. Also, be careful not to spay this onto any bushes. They will be killed - well, the branches that get over-sprayed will die. I'm looking at my front hedges where about 10% were hit by over-spray and all the leaves are dead. Hopefully, the rest of that bush will be tough enough to make it through winter. It was already stressed from some shade problems that have been solved. I would post some recent photos, but we haven't had rain in a few weeks, so even the bermuda has lost the green from lack of water. When the grass is green, it is clear which weeds were killed. I probably had 10 different types a undesirable weeds in the yard from crabgrass, some moss, some low-ground cover (type of violet?), and sedges. Also have some of the neighbor's non-bermuda grass coming over too. Their yard has excellent grass, except where there isn't any dirt, just clay on the surface. Nothing grows directly in clay from what I can tell.

I have been buying it for years. It was on special here on Amazon. I would have bought a bunch, but was limited to 2 bottles. Bummer. I can get on sale at Menards. I would buy again if it goes on sale. They arrived intact.

Works great for all of my weeds, even creabgrass and yellow nutsedge. A+

In order for this to work u have to mix it exactly as they specify, any more dilution and it won't work at all. This is more cost effective than buying the premixed gallon sprayers but I wish it would cover a larger area like their other version. 6300 sq ft isn't a lot. You have to mix with water and use a sprayer which is a lot easier than using their hand sprayer. It does require more than one treatment. In one area of heavy weeds, it killed them but they came back after 3 weeks and I had to repeatedly apply 3 times. I had a lot of brambles aka brambleberry (very thorny tall plants with white flowers and fruits like raspberries/blackberries - same family rubus genus and are perennials that are very hard to get rid of since they spread through roots/tubers underground). I sprayed the leaves with this a couple of times and it killed the plants effectively. But be very careful, I made the mistake of not being careful and sprayed the neighboring azaleas and cherry blossom trees and it killed the azalea bush and the leaves in the cherry blossom tree and now turning yellow with holes. I think I may have killed my tree.

Effective for weeds and crabgrass here in the middle Tennessee area. Some types of weeds may take two applications to have them die back.

This concentrate is very handy to use with a pump sprayer, and when applied to weeds in my lawn per the instructions, works well to control pesky weeds every spring or summer.
