Weed killer before laying lawn

I have had my old lawn removed and am going to turf it. I have some "grass"? coming through, but because the lawn was like a meadow and covered in moss, they sprayed with weed killer.
I feel I should give it one more go, but want to be able to lay the turfs in the next 7/14 days. I have brought Resolva 24hr action, is this ok to use and can I turf a few days later? If not what is the best thing?
I will add, I'm not a gardener so I don't know about these things! any help will be appreciated.

 

Two thoughts:

yes apply weed killer. Resolver is "quick" because it contains a desiccant that makes the tops dry out, and appear dead, so you can see where you have been within 24hours (and respray anything that you missed) but the desiccant doesn't kill the plants thoroughly, for that purpose Resolva also contains Glyphosate which translocates to the roots and provides a pretty effective "kill", but that takes a couple of weeks.

However, the ground needs preparing for turf - that means digging or rotavating, levelling and firming - then you can lay turf. If you just put it on top of the ground, where the old lawn was removed, it won't grow / won't grow well.

The preparation is the same for a seed-sown lawn, and the timing now is coming up to the best time of the year for seed sowing, so you could consider that as an alternative:

The Pro's & Con's are:

Seed is much cheaper
Lots of varieties of seed mix available - from bowling green to hard wearing for kids football pitch!! but also shady-mix for any areas that have tree cover, or even wild flower mix ...
Turf is very environmentally unfriendly - an inch of best fenland topsoil stolen from the field and transported half way across the country ...
Turf is quick. You will be able to walk on it in, say, a month. Seed grown would be better not walked on until next spring, or being careful where / how much you walk on it.

 

Thanks for that. If I use the Resolve how long should I leave it before I lay my turf? there is just a light thin growth of grass coming through in places. Would there be anything better to use? I have a dog and cat.

 

Hiya Alta.
If it were me, I wouldn't bother with using weedkiller if it's only a thin growth of grass. I'd carry on and prepare the ground prior to laying turf/sowing seed. Of course, Kristen is much more knowledgeable than myself, and may suggest otherwise, but that's what I would do

 

Yes, I agree ... although there will be opinions and opinions!!

If its just grass then worst case it will pop up and grow through the new turf ... adding more grass to your ... grass! What you don't want is any pernicious weeds left behind, so if it looks like you have any of those then Nuke Them!

Resolva is expensive, so unless you need to be able to see where you have been, within 24 hours, (which I expect you do, this time around) then just use a generic Glyphosate-based weedkiller.
