Not Too Late to Kill Lawn Weeds

October 17, 2011

If your daytime temps are getting into the 60’s, this is a great time to kill weeds in your lawn. Turf experts agree that fall is a great time to kill lawn weeds. The cooler weather and shorter days in fall cause perennial plants (grass, shrubs, trees and perennial weeds) to restock their roots for the coming winter. This means weeds like Ground Ivy, also known as Creeping Charlie (see photo), as well as Clover and Dandelion are easy to kill this time of year.

Creeping Charlie

The reason: with all “the flow” inside the weed going to the roots, the weed zapping stuff gets soaked up by the leaves and goes to the roots killing the weed completely. And you are also “knocking-off” all those new weeds that germinated in late summer before they become big problems next spring.

So here’s what you do. If you have lots of weeds, one of your two fall feedings can include a weed control to kill the weeds without harming your good grass. Scotts Turf Builder WinterGuard with Plus 2 Weed Control does the trick for most lawns (for St. Augustine grass use Scotts Bonus S Southern Weed & Feed instead). The Turf Builder WinterGuard in the product grows the roots of your grass nice and strong to sustain your lawn through the winter months. And the Plus 2 weed control kills dandelions and other major lawn weeds. Here’s more good news: getting them now before they can spread will dramatically reduce the number of weeds next spring. A note of caution: If you seeded this fall, it is best to delay your weed control until your new grass has been mowed 4 times or if you are not able to get 4 mowings in before winter, delay your weed control until next spring.

Apply the WinterGuard Plus 2 to moist foliage (like when the dew is on the grass in early morning) on a day when rain is not expected for 24 hours and do not water after application. Daytime temperatures should reach at least 60 degrees the day you apply. For St. Augustine grass, Bonus S should be watered-in after application.

If you only have a few weeds, then spot spray them with Ortho Weed-B-Gon MAX plus Crabgrass Killer and feed your lawn Turf Builder WinterGuard (without the weed control.)  (Note:  If you have St. Augustinegrass, Bahia or Centipede; check the Ortho Weed B Gon label to make sure you get the right product for your lawn.)
