Clovers and Creeping Charlie - gone
By C. in Chicago, IL on 07/26/2011
I have tried just about everything to knock out Creeping Charlie in my lawn. Speedzone did it with ease. The results were noticed within days of the first application. It is an amazing product.

Well worth the money!
By Travis in Lenoir NC on 05/06/2011
Used and most of the weeds in my lawn were dead the next evening. It took just a couple days on the clover, but it's dead too!!!! Much better than round up and other brands I've used in the past that had little or not effect. I would highly recommend this to anyone wanting to get rid of weeds!!

Speedzone Lawn Weed Killer
By Steve in North Branch, MI on 04/02/2012
This is the only product I have ever used that is effective in low temperatures. It gives me the ability to kill weeds when they first appear in the Spring instead of having to wait for warm weather to be effective

Great product for treating majority of broadleaf weeds and great amount of product if you don't need 1 gallon size. I blanket sprayed at 1.6 oz per 1000 sq. ft. I could see results next day. On the 4th day black medic, clover, speedwell, dandelion are all curled up and brown. Will see the end result and if there are any survivors in 2 weeks.
By Jerome in Wetumpka,Alabama on 04/26/2016
This stuff REALLY works, I found its best when spraying the whole yard to use half of the recommend amount on your yard. It will turn some of the Bermuda grass a little yellow. After it rains a couple of time the grass will tun back to normal.
Better than most, but not all
By Randolph in Virginia on 04/25/2016
I got it for dandelions and it hands down takes care of what is visible in my lawn, but within a few days there are more dandelions sprouting up. Could just be that my neighbors are also infested with them, and don't seem to attempt to control them. I just applied a second spot spraying and it seems to do the job every time. Doesn't seem to work too well on clover. I did mix with a Horticultural Spray Oil as a sticker, but the clover hasn't died off yet after the second spraying. If the clover was as dead as the dandelions there would have been another star.
Worked a little too well
By Bryan in Ohio on 04/09/2016
Applied this product to my lawn using a hose-end sprayer. Mixed and applied per the instructions. It took a few days, but I've seen a noticeable change in the few dandelions and clovers that had popped. All are shriveling and dying. One thing I did notice though is that the product killed off some of my grass as well. At first just the ends were turning brown, but now entire patches of grass have died. My yard is a fescue/blue grass mix that is supposed to be safe from this product. Probably would not buy again due to the damage to the grass. Three stars because it did a great job with the weeds, but also did a number on my grass.

SpeedZone Lawn Weed Killer
By Jln in Sacramento on 09/28/2015
After many years of searching for the ultimate Weed killer. I finally found the one. My lawn was infested with clover, dandelion and spurge. I just used my knapsack sprayer that I filled with water and a splash of Speed zone. I sprayed my Lawn and saw immediate results. After a few days, the weeds died leaving my lawn healthy again. I had to repeat the process on the clover a few weeks later in the front lawn. The spurge however never came back. Just an amazing product. Just make sure you protect your skin and wear a mask as it is a toxic chemical. Once again,Speed zone a.k.a. the Ultimate Weed killer!

Dissappointed in Gordon's Speed Zone Weed Killer
By Bill in farmingville, NY 11738 on 08/27/2015
Followed instructions for proper concentration amount with water. Applied to broad leaf weeds throughout the lawn area applying with new sprayer (by hand). The broad leaf weed did not change color or welter. Sorry but the product did not hold up to its claim. Thank you.
By Jerry in Binghamton, NY on 08/16/2015
I have given a 3 star rating to Speedzone because I'm still in the process of attacking this tenacious weed. I tried SZ in the summer and it only wilted the weed but killed very few. I have read that the fall is a good time to apply SZ because the violets are taking in food for the winter months and more easily absorb the SZ. My advice is not to apply until the fall or spring when the violets are actively growing. To be continued.

Well,after searching for years for a product to kill of the Veronica (is it called speedwell too?), this product has worked best so far and hasn't hurt the grass. I'll put a 2nd application soon,my lawn is overrun by it.but I got impressive results from the first run using my 2gal sprayer at 1oz per gallon mix.

Only 50% effective on the clover and less on on dandelions & etc. Not very satisfied at all!!
We are sorry that you are unhappy with your purchase. Many post-emergent herbicides will require a second treatment, especially in the summer months when weeds may not be actively growing. Per the product label: "Spray when broadleaf weeds are young and actively growing for best results. Speed-Zone Lawn Weed Killer may be applied in the spring, summer, or fall. Spring and fall treatments under adequate soil moisture conditions are preferred to the summer treatments. Broadcast (entire areas) applications or follow-up applications at 2-6 week intervals are recommended for more mature weeds, for dense infestations, and for adverse environmental conditions. Spot treatments during the summer may be appropriate for sparse infestations, or as a follow-up treatment, or any time broadleaf weeds are susceptible." Please let us know if you have further questions by calling us at 866-581-7378 M-F 9a-6p EST.

QDoes SpeedZone contain a surfactant?
I plan to use SpeedZone for spot treatment of Ground Ivy. Addition of a non-ionic surfactant is typically recommended for liquid herbicide application to broadleaf weeds. I do not see this recommendation on the label, nor do I recognize a surfactant on the ingredient list.
ASpeedZone Lawn Weed Killer Concentrate does not contain a surfactant. We do highly recommend adding a surfactant to increase the sticking and penetration power of SpeedZone Lawn Weed Killer Concentrate. You can use a surfactant like Non Ionic Surfactant For Herbicides.

QHow soon can Speed Zone be re-applied?
I sprayed the yard about 10 days ago and I don't see any signs that the creeping Charlie is dying. I don't think I used enough product when I mixed it.
A The SpeedZone Lawn Weed Killer Concentrate may be reapplied at 2-6 week intervals for more mature weeds, dense infestations, and for adverse environmental conditions. Make sure that you have measured the lawn area to be sprayed. Once you have the square footage of the treatment area you may then mix the labeled amount of SpeedZone (depends on your grass type) with water. Please note that the amount of water that is used is not important, what is most important is that you use the labeled amount of SpeedZone over the area you are treating. How to Calibrate Sprayers 1. Mark an area of 1,000 square feet (i.e. 20 by 50 feet, or 25 by 40 feet). 2. Place the sprayer on a level surface and add water noting the final level of water in the spray tank. 3. Spray the marked area with a sufficient volume of water to provide uniform coverage. Refill the sprayer to the same level as before measuring the amount of water added. The measured water added to the sprayer is the volume needed to cover 1,000 square feet. 4. Determine the application rate (fl oz/1000 sq ft) - 1.1 oz per 1,000 sq ft up to 1.5 oz per 1,000 sq ft (depends on grass type) 5. To each volume of water used, as measured in step 3, add the amount of SpeedZone as determined in step 4. Example: If the sprayer used 2 gallons of water to cover 1,000 square feet and the desired application rate of SpeedZone is 1.4 oz/1,000 square feet, then you would add 1.4 ounces of SpeedZone to every 2 gallons of water to be used.

QHow safe is this product around trees and shrubs?
I have 4+ acres to treat and many trees, some ornamental and specimen hybrid conifers. There is a lot of lawn area however needing treatment.
ASpeedZone Lawn Weed Killer Concentrate is reasonably safe around trees and shrubs. However, you should be careful not to get any overspray onto any desirable plants. trees, or shrubs. If you are treating your lawn that is close to desirables then it would be recommended to use a shield of sorts to prevent drift from getting on your desirables.
