I want to lay centipede grass sod down in my back yard, but I have a weed issue back there.?
Question:Can I just lay the sod down on top of the existing weeds or should I remove them first. Its a new home and the weeds grew in my unsodded back yard. I would say the weeds cover about 60% of the ground and they are mixed with some bermuda grass that I tried to grow by dropping seed. Any suggestions??
Answers:
You want to kill off any weeds that are actively growing. Otherwise, they'll grow up through the sod. In this case, the Bermuda grass is also a weed, since you want a Centipede lawn. So you want to kill that too.
Buy some Round Up concentrate and a 2 gallon pump sprayer. Mix up your Roundup and spray the entire back yard. In about a week, everything should be dead. Then, cut the dead grass and weeds on a very low setting and pick up the clippings. Voila! You're ready to put down your sod.
if i were you i would take out alll the weeds first so they wont mess up your yard!
i would mow down or weedeat all the weeds before putting down the sod. once the grass takes it will take over and choke out all of the weeds. centipede will run but you have to keep it mowed but do not cut it too short.
I suggest that you first pull out any of the tougher weeds (dandilions, thistle, etc), as well as the invasive ones (creeping charlie!), then mow what you have left over with the lawn mower. Then you should be able to lay your sod down, and if you keep it watered, while giving you a good looking lawn, it should also kill anything that's underneath it!
Kill the weeds first.
