Speedzone is a post-emergent herbicide only: it does not contain any fertilizer. You can apply fertilizer as needed since it should not interfere with your herbicide application. Just be sure you do not mow within 2 days of an application of Speedzone.

SpeedZone Lawn Weed Killer Concentrate is labeled for and will treat for PA Smartweed. Please reveiw the product label to make sure your turf grass is tolerant of this product. ? You can help prevent the smartweed from coming back by using a pre-emergent such as Weed Impede to help prevent it from growing. We recommend that you consult with your local cooperative extension office Master Gardener on uses of lime and specific fertilizers needed on your turf based on the needs.
SpeedZone Lawn Weed Killer Concentrate is not labeled to treat Lesser Celadine. Herbicides which contain the active ingredient glyphosate, such as Round Up, are effective in controlling (but not necessarily eradicating) lesser celandine. Applications should be made in late winter or early spring when leaves are visible, but prior to full flowering, and when temperatures are above 40°F. Glyphosate will impact other vegetation so try to target only the celandine. It may take 1-2 weeks before the full effects of the treatment are visible.
Yes, SpeedZone Lawn Weed Killer Concentrate is labelled for deadnettle. Please refer to the product label for mix rates depending on the turf type you have.
SpeedZone Lawn Weed Killer Concentrate is not labeled to treat rescuegrass.
Unfortunately, there is nothing labeled to treat rescuegrass post emergently in your Bermudagrass. For post emergent control, you would need to spot treat with a non-selective like Roundup QuikPro and reseed/sod. You can use a pre-emergent labeled for rescuegrass to help prevent it from coming up the following season. You would apply it in the spring and the fall and it will prevent the rescuegrass and other weeds from germinating and coming up.
The product label for SpeedZone Lawn Weed Killer Concentrate does not list whether it will harm liriope, monkey grass, or mondo grass. These grasses are generally very hardy and only killed with non-selective herbicides such as glyphosate. We would recommend testing a small area first to be sure.
SpeedZone Lawn Weed Killer Concentrate should be mixed at 1oz per gallon to cover 1000sq feet.
SpeedZone Lawn Weed Killer Concentrate already contains a small percentage of surfactant so you do not add another one. It could cause permanant damage to the lawn or it may only be temporary, it really depends on the rate you use and if your lawn is under any type of stress such as drought or heat.
Since SpeedZone Lawn Weed Killer Concentrate already contains a small percentage of surfactant and an additional surfactant is not advised on the product label and Drive XLR8 DOES require the use of a Methylated Seed Oil Surfactant for best results to treat crabgrass, we would not advise to tank mix these together for one application unless you test a small area of the lawn first.
If adding a surfactant to SpeedZone Lawn Weed Killer, you could possibly temorarily or permanently damage your lawn. We would recommend doing a small test spot application to the lawn to see if your turfgrass would be tolerant to using both in one application.

If you're trying to kill Quackgrass in your flower garden, then we wouldn't recommend using SpeedZone Lawn Weed Killer Contrate as it is not recommended to be used over flower beds.
