Can I roundup on naked dirt, before lying sod?

Question

I had a ivy vines eveywhere (i'm not sure if it's call ivy mat) in my yard. I pulled all out and digged to soften the dirt. but I can see there are so many tiny roots still under and mixed in the dirt. I am planning on lying sod in mt yard but I am very concern that the vines might come after i lyed the sods. What can I do to make sure that the mini roots are not going turn into long vines in future. There's no way I could get rid of every little roots.
Is Roundup only for growing plant or can I spray on naked dirt? So stressed out! I am lost in full of dirt in my yard.
Thanks so much for your time.

Answer 1

put down newspaper over the old vines, then lay a thick layer of top soil before laying the sod. about 10 sheets will kill it off, and it will rot down. the roots will die within a couple of months because they will have no photosynthesis to keep them alive. You could also use landscape cloth, but newspaper is cheaper and works as well if not better, and you won't have to worry about drainage. It will be a pain, but this is the best way to ensure the ivy (which is very invasive once established) doesn't return. Round up won't work on roots, and it can stay in the soil long enough to harm the new sod.

Answer 2

it only works on vegetation not on dirt, let it grow again and give it a good spray. you can buy a once a year herbicide for soil but nothing will grow for a year.

Answer 3

No, please don't. Loosen the soil a little, sod, roll moderately, apply starter fertilizer, water, and keep moist until rooted in. Do weeds in a couple of months.

Answer 4

Just make sure that it has a pre emergent in it
