to seed or not

So I clear an area of an overgrown garden - bramble, willow herb etc.

One section which was mostly grasses has been turned over to veg. The other section more problamatic. Had intended to grass seed it this year. However I am digging a lot of roots and I am sure I have missed a lot. Would I be better not seeding this year but instead leaving bare and dig or spray up any bramble etc that appear.

I’d give it a bit longer ... see what brambles etc grow this summer ... spray the leaves with Roundup while its growing strongly ... this means the glyphosate will be fed back into the roots and kill them. 

Don’t touch until all the leaves are brown ... this means the roots are dead. 

It may need two or even three applications to get it all.  

Then you can prepare the ground to sow the grass in September ... IME absolutely the best month for sowing a lawn 😊

To make it a bit more appealing, if it's in full sight of your house or patio, you can fill a few large pots with summer bedding flowers.. and just move them well out of the way for 24 hours when you need to spray.  Just line them up along the edge of that area for something nice to look at while you wait for greener days.

Thanks for helpful replies. The area of ground adjacent to this has not been cleared as yet. My intention was to brushcut last years willow herb stems to approx 12" then spray the area to kill any new rosettes. What would be the best herbicide to ensure the roots are killed.
