Quackgrass is more complicated to control than other weeds. Many weeds can be controlled with "selective" herbicides - ones that kill specific plants and leave all others unaffected. Unfortunately, there is no selective herbicide available to control quackgrass in lawns. To control quackgrass chemically, a "non-selective herbicide" is required. A non-selective herbicide will kill all growth it contacts.

You can try spot treating the quackgrass, knowing that adjacent grass will be killed, or you can try starving it out. Frequent, close mowing can be an effective way to control quackgrass. Quackgrass grows faster than bluegrass and fescue and is therefore more susceptible to damage from the mowing. If you use this method, fertilize and water your lawn on a regular basis. A healthy lawn is less likely to be damaged from the stress of close, frequent mowing - though there is always the risk of some damage, even to a healthy lawn. For fescue lawns, mow not closer than 1.5 in.

Best wishes with your lawn!
