How to Kill Dandelions and Not Your Grass
Dandelions! You dig them… they grow back. You put down a crabgrass preventer earlier this spring, but you still got dandelions now. You try to dig them and they just pop up again. You ask, “So… what’s the secret to killing dandelions and other weeds in my lawn without hurting my grass?
Dandelions and other weeds like thistles have long taproots that can go down a foot or more. If you try to dig them and don’t get all the root, it will simply send up a new weed to replace the one you thought you got rid of. So digging can be hit or miss.
Some folks think you need to put the weed & feed down before the weeds appear. Not true. Unlike the crabgrass preventer that goes down before you see the crabgrass, most weeds are perennials and can’t be prevented because they grow back from their root as well as from seed. So for dandelions and many of the weeds in your lawn you kill them after you see them. Here are your options.
For lawns with lots of dandelions and other weeds: Spread Scotts Turf Builder Weed and Feed to a wet lawn. That’s because the weed control enters the dandelions through the leaves and is transported to all parts of the plant including the roots. Then within a few days, the dandelions will begin to curl up and wither. Gradually over a period of about 3 or 4 weeks, they’ll fade away, roots and all, so they can’t grow back. If rain is expected within 24 hours, wait until another day. I find it best to apply early in the morning when the lawn is covered with dew.
For lawns with a few dandelions and other weeds: If you only have a few weeds, you may not need the weed & feed on your entire lawn. You can spot treat weeds with Ortho Weed-B-Gon MAX plus Crabgrass Killer and then keep your grass healthy with a feeding of Scotts Turf Builder. The Turf Builder Lawn Food is important as it helps your grass grow to fill in the spots where the dandelions once hung out.
Also keep this in mind: getting rid of the weeds is only half the battle. Your lawn will be a stronger competitor against new weeds if you feed your lawn regularly (about 4 times a year) and mow your grass a little bit taller. Most lawns are healthier if the grass height is 2-1/2 to 3 inches tall after you mow.
