Return of the Evil Lawn Weeds

September 17, 2012

It’s like part two of some bad movie you didn’t want to see the first time around.  It’s “The Return of the Evil Lawn Weeds!” starring dandelions, chickweed, clover, ground ivy and a bunch of other weeds you thought you did away with last spring.  What are they doing in your lawn this fall and more importantly, what can you do about them?

Ground Ivy, also called Creeping Charlie, is more easily killed in fall.

The weeds are out there because the wetter, cooler fall weather is the ideal time for them to grow.  The good news is you can terminate them the same time you feed your lawn this fall with Scotts Turf Builder WinterGuard Weed & Feed, or if you only have a few, you can spot spray them with Ortho Weed-B-Gon MAX plus Crabgrass Killer  OR Roundup For Lawns after you have fed your lawn with Turf Builder WinterGuard (the lawn food without the weed control in it).

Why is this a good time?  Because they’re growing right now, weeds really soak up what you put down right down to the root, so they’re completely destroyed.  Plus, getting them now, before they spread, will dramatically reduce the number of weeds in your lawn next spring.

Put down Turf Builder WinterGuard with Plus 2 on moist foliage on a day when rain is not expected and do not water the day you put it down.

If you have St. Augustinegrass, use Scotts Bonus S Weed & Feed to control your weeds.  Water after spreading this product.

One last bit of advice:  If you put down grass seed this fall, you should not put down weed controls is those areas you seeded until after your new grass has been mowed 4 times.

    Hey Ashton,
    I have already laid down a weed control product in my lawn(today to be more precise). I have Bermuda grass in North Texas. I have some patchy areas I’d like to repair via seeding. I have been advised if you you use weed control products, and attempt to seed afterwards, the weed control product can prevent the seeding from growing. Is this true? What are my options about seeding at this point?

    Thank you for your time.

    • Hi Jason You are correct that your fall applied weed preventer will prevent grass seed from germinating this fall. However since the best time to seed bermudagrass is spring, it will be ok to seed at that time. Just remember not to put down a preemergent next spring.

    My soil sample came back tell me to apply lime. We have had so much rain in Kentucky that I went ahead and put it down and have been waiting to kill my weeds. Is there an ideal amount of time to wait after putting down lime before I use ortho weed b gone plus crab grass control. Creeping Charlie and crab grass rule my life.

    • Hi Megan
      You can treat your weeds anytime. It is best to pick a day when rain is not forcasted. The crabgrass will die with a heavy frost, however the Creeping Charlie will continue to grow. This is a good time of year to kill Creeping Charlie.
