Controlling Clover and Thistles in Your Lawn

Controlling Clover and Thistles in Your Lawn


Controlling broadleaf weeds in a lawn can be a frustrating task, especially when the broadleaf weeds are the difficult-to-control types like white clover and thistle. The most effective method of controlling them is to maintain a dense and healthy stand of grass. Proper maintenance of a lawn is a combined program of adequate fertilization, proper mowing practices, adequate watering, and any necessary disease and insect controls. However, even the best-maintained lawns can be invaded by weeds.


Any area of a lawn that is stressed, thin or has bare ground showing is susceptible to weed seeds getting started and then weeds to consequently get a foothold in that area. When this happens, careful use of selective post-emergent herbicides can control the unwanted weeds.

Zamzows Ultimate weed control for lawns is the perfect choice to kill any weed in your lawn. Unlike many of the other weed control option out there, Zamzows Ultimate can be used at temperatures in the 40's. Because it is still effective at these cooler temperatures you can begin spraying earlier in the year, giving you a jump start to making your lawn weed free as early as possible.


Applications during July and August are not generally recommended because weed control is often poor and it is possible to damage the lawn and surrounding vegetation. This would be especially true when applying liquid herbicides in a hose-end sprayer. However, if applications are desired in July or August, spot spraying individual weeds with liquid herbicides from a tank type sprayer. temperatures


Adding Zamzows Stay Put helps the mixture adhere to the leaf so more herbicide is absorbed into the leaf. Spot spray the leaves of each weed to run off, spraying only the weeds needing control. Clover will most likely require two applications to eradicate it entirely. Thistle is more difficult to eradicate and may require three or more applications. Multiple applications should be made approximately 7-10 days apart.

During fall, herbicides quickly move through the entire plant and new weeds are less likely to fill in the open areas left by the dead weeds. It is the perfect time to reseed those open areas with grass seed and restore the thick healthy lawn.
