How to Get Rid of Weeds in a New Lawn

Updated February 21, 2017

Whether you are planting a new lawn for a newly constructed home or your lawn needs a complete overhaul and you have decided to start from scratch, your new grass is not immune to the invasion of weeds. When you plant a new lawn, it is important to start weed control methods immediately to ensure a lush green carpet of grass that is free of invasive weeds. Professional lawn services can offer protection from weeds, but cost more than the amount it would cost to control weeds yourself.

Begin your weed control efforts before the grass is even seeded. Use clean top soil or fill dirt if you are adding a soil layer prior to planting your grass and only used cleaned straw for covering the new seed, not hay. Top soil and hay that have not been cleaned may contain seeds or cuttings of weeds when you spread them.

Pull weeds by hand as they appear, using gardening gloves to avoid blisters or thorns. Start doing this about three weeks after you seed the lawn. If you attempt to do this too soon, you could crush new grass where you walk or kneel and cause it to die.

Spray weed killer onto the weeds that you see to kill them. Allow your grass to grow enough to mow it three times before you attempt to use spray-on weed killer, otherwise the fragile new grass growth will die-off along with the weeds.
